Decisive Battles: Frontiers 1914 - Part 7: Discussion and Conclusions.

We've finally reached the end of our long trail through the "Battle of the Frontiers" in August 1914. 


Working backwards from here we looked at the final portion of the "crisis" of mid-to-late August just this past January when we looked at the engagements along the Franco-Belgian frontier between the German right and Anglo-French left.

Before that we had a long lacuna - my fault and I apologize for it - before we discussed the other two engagement areas, the Southeast (where the French attacks into Lorraine were beaten back but the German counterattacks stalled in the Trouée de Charmes) and the Central "Battle of the Ardennes" that was perhaps the single biggest driving force behind the failure of the French Plan XVII and MAR Joffre's grand tactical operations, way back in July of 2025.

In May 2025 we took a side arc to look at SIGINT after taking a dive into the first meeting engagements that were the main event during the second two weeks of August.

February 2025 took us to the mobilization and deployment of the combatant armies during the first week of August. 

In 2024 we broke down the opposing sides' aerial reconnaissance assets in  November and the ground reconnaissance elements in September. We detailed French war planning and German war planning over the summer of 2024, and began with a brief scene-setting discussion of the geopolitical setting of Western Europe at sunrise on 1 AUG 1914.


To cite myself from the first entry in this series, the reason we did all this is because:

 "The origins of this series go back over a decade, to the 2009 piece on the...First Battle of the Marne

In the course of researching and writing that article my attention was drawn to the tactical issues that arose from both combatants' mis- (or lack of) understanding of their opponents. A lot of the "whys" of the Marne ran directly from the failure of strategic and/or tactical reconnaissance.

Neither side really accomplished either of their reconnaissance or security objectives, and the result was the chaotic collision that we call the Marne.

The question that I kept coming back to was...why not?

Was the problem baked into the larger operational or even the strategic planning? 

Was this the result of both sides' failure to anticipate the tactical "facts on the ground" affecting reconnaissance and making plans that assumed conditions that no longer existed?

Or was it technical, the conditions themselves, that had changed beyond the ability of clever plans to account for them? Was the problem that the older means and methods of reconnaissance - horse cavalry and light infantry - and security were just no longer effective in the tactical environment of 1914, and the new techniques - air reconnaissance - un- or under-developed to the point where the commanders didn't receive (or were unable to process) the intelligence?"

Well, now we've looked at the events of August 1914 to a fairly granular level of detail, and we need to discuss what, if anything, they tell us about our hypotheses. 


Were there critical failures - either of the physical reconnaissance activities of the respective armies, or of the interpretation (or lack of interpretation) of the intelligence those activities generated? And did those failures, assuming they occurred, result in combat results that led to the failure of the presumably-war-winning plans of one or both opponents.

Before we can answer that question, we need to take a look at the combat results that appear to show the effects of those reconnaissance or intelligence-analysis failures.

So...

Where can we find combat actions that reflect reconnaissance failures/analysis failures in August 1914?

Starting from bottom to top (in reverse order of the post list we started from), then, I'm going to pull out the following by area: location and (army affected) as the proofs of our hypotheses:

Center: Eastern Belgium (Germany) - Belgian defenses, including the setup of the fortress belt around Liege and their effect on available/practical German axes of attack.

Southeast: Lorraine (France) - Failure of the French 1er and 2eme Armee recon units to detect the German counterstroke that became the defeats of Morhange-Sarrebourg.

Southeast: Lorraine (Germany) - Failure of 6. and 7. Feldarmee to detect the French defenses that resulted in futile bloody attacks on the Charmes gap.

Center: Ardennes (France) - Failure to discover the presence of the three German field armies which resulted in the brutal defeats of 22-23 AUG during the Battle of the Ardennes.

Northwest: Central Belgium/Northern France (Germany) - Failure to find the BEF/western end of the Franco-British MLR in a timely fashion.

Northwest: Northern France (Germany) - Several failures to find (or correctly interpret reports of) Allied defenses at, then movements from, Mons, and the Sambre-Meuse lines, to the Marne.

Let's take a look at each in a bit more detail.


Eastern Belgium (1-16 AUG):
There seems to be some agreement amongst military historians that OHL's timetable for the passage of eastern Belgium around Liege was a bit overoptimistic, but the actual time that the combination of Belgian resistance and German tactical and logistical foul-ups cost the right-wing advance isn't a fixed value.

Showalter (2019) - who's thesis, remember, is that reconnaissance problems in August cost Germany the campaign, at least, if not the war - says that, yes, recon (and operational/movement) problems did hold up the three right-wing field armies, and provides estimates for the delay ranging from two days to 4-5 days to none (citing the German official history that the predicted date of arrival for 1. Feldarmee at Mons was 23 AUG, so right on time).

The other element here is the question of what operational or tactical problems did reconnaissance failures lead to, and how did - or did - they impact the German offensive.

Certainly the failure to find the Belgian field fortifications between the fixed forts around Liege cost the Maasarmee in lives. How that impacted the larger campaign, though? That seems difficult to exaggerate. All the combatants were unprepared for the bloody cost of assaulting dug-in defenses, of which Liege was just the first of many. And when the German infantry finally did overrun the inter-fort defense lines and seize the city center it had little effect, if any, on the fortresses themselves; the heavy siege guns were still required to blow open the steel and concrete and reduce the Liege strongpoints before the right wing maneuver forces could proceed west.

So my thought is that the first of our recon-failure problems didn't have much of a campaign-level (much less war-outcome level) impact. 


Lorraine (14-26 AUG):
I think we can lump both the French failures of mid-August (the "Battle of Lorraine" or Morhange-Sarrebourg) and the German failure at the Charmes Gap in the third week of August (the "Battle of Trouée de Charmes") together.

I also think that we can relegate both to the same sort of "fairly minimal impact" bin we put Liege.

Yes, both the 1er and 2eme Armee, and the 6. and 7. Feldarmee, recon units made some tactically (and in human terms) lethal errors.

Had those errors been avoided? I don't see either making a real operational or strategic difference.

Both French and German offensives in Lorraine were going to be limited by the opposing fortress belts, as well as by the impact of operations elsewhere along the frontier and the tactical realities of 1914 combat. I see the possibility of a decisive French breakthrough around Sarrebourg, or a Bavarian breakout through Trouée de Charmes, as somewhere between unlikely and impossible even had the aviators and cavalrymen on both sides absolutely nailed it.

So, again, ugly in human cost, fairly minimal in the "battles that could have changed history" value.

Meaning we're left with the other three third-week-of-August failures; the German failures find and fix the Anglo-French left in Flanders - both before and after Mons/Charleroi - and the French failure to figure out what was going on in the Ardennes before the horrific collisions of 22-24 AUG.


Flanders (19-24 AUG):
This takes in both the initial failure to find the open left flank of the Anglo-French defenses and the repeated failure to cut off the Allied retreats.

The German recon failures can be attributed to several issues; 1) the tactical mis-employment/poor logistical management of the strategic HKK cavalry units, 2) misdirection of aviation patrols, and 3) poor transmission of, or incorrect analysis of, aerial reconnaissance reports when they did arrive.

We'll discuss this in depth after we go through the scenarios, but the bottom line is OHL's management - from initial deployment to movement orders to logistical support - of the HKKs was generally poor. The cavalry units in the field seem to have tried their best to accomplish their missions (with the caveat that engagements like Waremme and Haelen were a cautionary tale that shouldn't have taken the lives of men and horses to have figured out beforehand) but OHL's overall strategic/grand tactical direction was appalling. 

HKK 1 was useless for most of August, not because of it's (or it's commander's) fault but because OHL's initial deployment was fucked up as a football bat. HKK 2 did better (and was tactically outstanding at Le Cateau) but was still largely wasted through poor command and control from its OHL higher as well as a poor (or lack of) coordination with the field army commands that should have been getting information from the HKK's work.

German aviation seems to have been on top of reconnaissance in the field - the feldfliegerabteilungen were on top of it, anyway, though there was a larger issue with aerial assets that we'll discuss below - but the problem there was, as we discussed, a combination of poorly organized staff work (specifically the lack of a Ic aviation intelligence officer on the corps and field army staff) and an unwillingness of the field army commanders - Kluck and Bulow - to abandon preconceived ideas when presented either with contradicting intelligence or conflicting intelligence when some of the reports supported their convictions regardless of the relative number or value of the report they wanted to be correct.

That said...the larger operational/logistical/time-and-space questions that surround the whole "strong right wing" concept are hard to avoid.

As we discussed back when we talked about First Marne, the real question seems to be whether the entire right wing sweep originally envisioned by Schleiffen was militarily practical.

The lack of usable road axes of advance, and the problem of road-logistical mobility away from the railheads (and the inability of the eisenbahnbautruppen to extend those railheads in real time to keep up with the maneuver units), has been pointed out since 1918 and brings into question whether, even had the German horsemen and fliers quickly found the BEF and identified the open country west of the British, the German right wing could have effectively enveloped the Allied left with enough force to have shattered the defenses and forced a French capitulation.

So...troubling?

Yes.

Decisive?

I'm not convinced.

Let's look at the final scenario.


The Ardennes (14-24 AUG):
This really was the "crisis" of the Battle of the Frontiers. If you can point to one single failure of reconnaissance that impacted the Battle of the Frontiers it's the French failure to find the German 3., 4., and 5.Feldarmee in the Ardennes before the French FLOT was hammered flat.

Mind you, the French failures in the Ardennes are multifarious and cascading, beginning with the poorly directed, seemingly random wanderings of Sordet's cavalry corps.

They include flawed grand tactical and tactical concepts of operations, from GQG down to battalion level. Top-down, rigid, orders-driven command and control and a punitively slow orders-issue-cycle timeline that commonly meant that even when intelligence was received and analyzed in a timely manner the resulting orders were issued hours, or even days, too late. Crude tactics, including a lamentable inability of many French maneuver commanders to understand and conduct combined arms operations.

The overall narrative of the Ardennes is the French offensive bumbling blind into the woods to be surprised and decimated by a German advance that had better intelligence and more rapid, more responsive tactical reactions to the encounter battles of August.

Given the larger operational situation I don't see how Joffre's Plan XVII concept would have resulted in the "breaking the hinge" between the German left and right he envisioned even had French cavalry and aviation recon work been immaculate.

But had his central front armies been better aware of the buzzsaw they were walking into Joffre might have been able to at least stabilize the front lines much closer to the French borders and prevented the loss of so much of the coal- and iron-ore fields and manufacturing capacity in northeastern France that handicapped the French war effort.

So those failures?

Pretty damaging.

Now that we've discussed the where and when, let's talk the "whys".

Performance of the reconnaissance elements in August 1914

Infantry In our look at who was doing the recon work along the Frontiers we quickly dismissed the historically-oldest "recon" units on the ground, the "light infantry" scouts, and I'll stand by that assessment.

While still useful for local tactical recon the riflemen, jagers, and chasseurs/voltigeurs were simply too slow to contribute much more than that. A smart infantry battalion or regiment or brigade commander still had his scouts out, but for doing things like finding BEFs or preventing Ardennes disasters?

Nope. The guys just didn't have the legs anymore.

Cavalry Here we have to separate the "local" cavalry - for the French, and British, the corps and for the Belgian and French the divisional cavalry squadrons - which did just slightly more than the light infantry did, and the "strategic" cavalry; the German HKKs, the French Sordet's 1er Corps de Cavalrie, and (to some extent) the British Cavalry Division.

And here we also have to distinguish between the overall physical/technical constraints to all cavalry operations in 1914, the tactical abilities of the opposing sides' mounted units, and the operational control exerted (or failure to exert) by OHL GQG, and the BEF GHQ.

All cavalry in 1914 suffered from several problems imposed simply by the conditions of warfare at the time.

Scale, for one. The distances the horses were asked to move, and the short time require to move through them, were punitive. "Modern" war meant that human and animal endurance was pushed to, and beyond, their limits. All the "strategic" cavalry commanders, French and German, complained of the losses their units suffered simply from the wear on legs and backs, the loss of horseshoes and lack of fodder, from long march days and distance from - or lack of - resupply sources. 

Several whole days in August were lost because it was a hard choice between stopping operations to rest the horses or pushing ahead and ruining, or killing, them. 

Another was the greatly improved range, accuracy, and lethality, of both direct and indirect, fire of 1914 compared to the last big European wars of the 1860s and 1870s.

Simply stated, in August 1914 a man-sized target that could be seen could be hit, and, if hit, killed or badly wounded in a way that in 1870 would have been a challenge if possible at all. A horse-sized target? Damn near unmissable.

A mounted cavalryman in 1820 or 1870 took a chance scouting out his enemy's infantry position.

In 1914? The chances had become damn near certainties.

Lethal. And that's without even considering artillery.

So the option of cavalrymen "fighting for intelligence"? On foot, maybe. But that meant that once within rifle- or artillery-range of possible enemy main force elements the cavalry's mobility was reduced to a slow foot-pace sneak-and-peek to avoid blundering mounted into someone's machinegun beaten zone.


So both sides had over-optimistic ideas of how effective at reconnaissance their cavalry (and their enemy's cavalry) would be.

That said, there do seem to have been some issues that affected the French and British cavalry differently than the German.

On the operational level, the French GQG and British GHQ seem to have done a very poor job determining the objectives and directing the employment of, and collecting the information from, their mounted units.

We've discussed the futile wanderings of Sordet's troopers. The British cavalry seem to have been poorly used, although the scatterbrained deployment of the Cavalry Division doesn't seem that much more scatterbrained than Field Marshal French's August work in general.

OHL misallocated (as we also discussed) the HKKs initially, leaving the right flank spaces largely vacant and shoving four of the five into areas where they were either hemmed in by vegetation (HKK 1) or simply crowded out by infantry masses (all the others except HKK 2), and then freeing up the one that could have been useful (HKK 1) too late.

Better than GQG, which seemed to forget about Sordet altogether for days at a time. But that's a damn low bar.

At the tactical level the French cavalry, in particular, seems to have performed poorly. This 2020 article reports that in the Ardennes:

"The inability of the French cavalry divisions to obtain an accurate picture of the advance of the German 4th and 5th Armies led to serious mistakes in French operational and tactical planning. Due in great part to IR88’s success at Longlier, the French 4th and 9th Cavalry Divisions were pushed out of the way of XVIII AK and were not able to determine what the Germans were doing, nor hinder their movements. The anonymous author of the FAR (Feldartillerie Regiment) 25 regimental history said that the French cavalry simply would not fight. (italics mine) 
From the smallest patrol up to the level of cavalry corps, the French cavalry avoided combat and when it unexpectedly did meet German forces, such as at Longlier, the French cavalry withdrew. The German cavalry was able to screen the movements of its own forces, while on 21 and 22 August it provided accurate information concerning the French advance."

The British cavalry, at least according to Zuber, was similarly averse to fighting for intelligence (or fighting at all but, then, Zuber...):

"In reconnaissance, counter-reconnaissance and rear-guard operations the British cavalry from 21 to 27 August was utterly ineffectual. Whether the British cavalry was superior fighting dismounted, as Jones contends, is a moot point, because it didn’t fight dismounted, but made a practice of withdrawing before the Germans could make contact.

Before Mons the British Cavalry Division failed to perform its reconnaissance and counter-reconnaissance missions. On 24 August it left the II Corps left flank floating in the air. On 25 August it failed to delay HKK 2 and IV AK. At Le Cateau it failed to provide even local security and, citing exhaustion, did nothing. The British Cavalry Division in August 1914 was an operational liability."

Much as German infantry/artillery tactical doctrine and training seem to have been more effective than the Belgian, British, or French, the Imperial cavalry seems to have been better prepared for August 1914 than their enemies.

(How much of this was, at least in part, owed to the attachment of the jager battalions I'm not sure...but at least some must have been. The German HKK cavalry divisions had in their light battalions a serious direct-fire force multiplier that neither the British nor the French had in August 1914.)

So some of the cavalry reconnaissance difference - both in general capabilities, and in increasing (for the Allies) or decreasing (for the German) the impact of the errors - looks like it was directly related to the organizational, doctrine, and training advantages of the German reiter.


Aviation
This is where I suffer from a source disparity.

Bowden (2017) is a comprehensive source for all fixed-wing-aviation-things German. I have a highly detailed account of what the Fliegertruppen des deutschen Kaiserreiches did, how well (or poorly) they did it, and what impact it had.

I have several fairly decent on-line sources for the Royal Flying Corps. Not nearly as exhaustive, but at least covering the general activities of the British fliers.

I've even got some okay-ish sources for the Belgian air element. 

France?

Nothing. Zero. Zip. Nada. 

Okay, now...here's the thing. As we've discussed, the "most dangerous enemy course of action" for France in August 1914 was the Ardennes offensive/counteroffensive, and we know that particular sector was the least conducive for, and most poorly visible to, aerial reconnaissance.

So it's entirely possible that the Armee de l'Air was busting it's Farman ass over the wooded hills of the Ardennes but it just wasn't helpful in seeing through the canopy.

But given my lack of French sources?

I've got no idea one way or the other.

Here's what I do know, specifically about the German aviation efforts.

Technically the German fliers seem to have been solid, at least as good or better, than their French or British counterparts.

(The caveat being that in August 1914 "aerial reconnaissance" was entirely about reconnaissance; the idea of "security" - that is, denying your enemy's eyes in the sky access to your positions on the ground - was not only impossible in fact but hadn't really even occurred to anyone as a practical concept yet. 

The first "fighter"-type aircraft (that is, specifically designed to attack and destroy other aircraft to deny air recon patrols) first appeared in April 1915, and the first real designed-from-the-ground up "fighter" was the Fokker E.1 in July.

Where German aerial recon issues appeared they seemed to revolve more around a combination of 1) staff organization - specifically the overworked German corps- and field army-level Ic and the lack of an aviation-specific staff pogue - and 2) poor or deliberately obtuse interpretation by the receiving maneuver commanders.

What we know of the French and British leadership's decision-making suggests similar problems there, too.


However. I'm a bit baffled by the absence of one bit of aerial reconnaissance specifically; zeppelins.

Seriously.

When you consider the enormous time and effort OHL and the Imperial Navy put into the England raids - 51 bombing raids over two years involving 84 airships (of which 30 were lost to British fire or mishaps) dropping almost 6,000 bombs - for such meager returns, you have to wonder.

Here was a huge, stable platform, capable of carrying a radio, which (by January 1915, anyway) was capable of overflying the southeastern counties of England.

Yes, the gasbags seem to have had issues with ground fire (we discussed the three that were shot down in August when we talked about aviation assets in 1914) though the England raiders seemed to have significantly less trouble, losing only about four or five out of the thirty-odd to anti-aircraft guns.

You'd think that the combination of stability, loiter time, and radio commo would make an airship, at least one with a respectable operational ceiling, a perfect strategic reconnaissance asset.

Apparently they weren't. Was the problem low ceiling? (that certainly was a problem for Z VI, VII, and VIII) Size and speed? (even at high altitude an airship is a goddamn big, slow target). Observation? (was the "high enough to be safe" also "too high to see tiny stuff on the ground"?)

Whatever the reason, despite having and using them for reconnaissance missions at sea, the Heer had no use for them over the Western Front after the third week of August.

Go figure. 

Conclusions

Criticality: Were there any potential "war-winning" actions/event along the French frontiers in August 1914 that poor reconnaissance (or poor interpretation of/reaction to recon reports) caused one side or the other to fumble? Or "war-losing" moments that poor German recon (since Germany "lost" the war, at least in conventional terms) led to?

We've agreed that of the six occasions where there seem to have been problems with reconnaissance in one form or another two look like they had some larger implications; for France in the Ardennes, and for Germany in Flanders.

So..? 

Ardennes, definitely a huge problem for France; failure to find, and prepare for, the German attacks in the third week of August put paid to any hope - slim as it probably was - of Plan XVII "working" as it was supposed to.

The effect, however, was really less of a 'war-losing disaster" and more of a "forced to give up illusions of a war-winning victory". So troublesome, but not really "critical" to the larger outcome of the war. Gemany didn't lose, or France win, the war in the Ardennes in August 1914.

Flanders, a problem for Germany, yes, though more of a "limited the gains" problem than a "totally changed the outcomes/lost the war" between Mons/Charleroi and the Marne.

And in effect the reconnaissance failures seem likely to have balanced each other out; the French failure in the Ardennes was somewhat offset by the German failures to catch and kill 5er Armee and the BEF. Between them both they set the table for the collision along the Marne in September that effectively stopped the German invasion and started the grind of positional warfare that lasted for the following four years.


Responsibility:
 Why did the recon work that was unsatisfactory - for France in the Ardennes, for Germany in Flanders - fail? Was there an individual, or a branch, or an organization, training, or doctrine responsible?

Let's look at it by reconnaissance asset type. 

Infantry? No, other than poor overall French infantry/artillery training and doctrine. Infantry recon was a purely local task, and doesn't seem to have been involved significantly in either critical failure event.

Cavalry? Yes. To an extent, both in general and specific to one of the combatants.

The physical realities of modern war in 1914 meant that mounted cavalry couldn't possibly as effective at reconnaissance (tho at dismounted security both sides' cavalry was still fairly effective) as it had been, or that the highest levels of command thought it would be. Plans that depended on ground recon by cavalry units were destined to produce less-than-optimal results.

However, the degree to which those results were suboptimal seems to have varied based on national differences in organization, training, doctrine, and leadership. The German cavalry seems to have been better prepared that either the British or French mounted units. We simply don't have enough combat encounters to say anything about the Belgian cavalry.

Aviation? Also sort of yes-and-no. 

The actual flying contingents for which I have good or at least decent information - Germany and Great Britain - appear to have been technically competent and effective in the field to the extent which the state of their fragile and weather-dependent aircraft allowed. For the Belgian fliers, like their cavalry, I simply lack data, and the French fliers are a mystery shrouded in a source-free enigma. 

What was lacking was at the command and staff levels. The organization for collecting, analyzing, and reporting aerial recon information was either rudimentary or, often, so poor that it broke down under combat stress. And the maneuver commanders - the German field army commanders and OHL, the French army commanders and GQG, the British corps commanders and GHQ - often disbelieved, or misinterpreted, or just ignored, the aerial recon stuff.

And, as we've mentioned, the closest to a "one simple war-winning trick" the air recon work seems to have come was the retreat from Mons/Charleroi, where if some of the sources are to be believed, quick and correct analysis of, and operations based on, several reports might have bagged 5re Armee and the BEF.

Might have.

After looking at all these events I'm not really convinced, though, and even less convinced that it was a problem of poor reconnaissance alone rather than a messy collision of the "fog of war", some poor field recon, and equally poor intelligence analyses.

In the end I think the culmination of the battles along the frontiers that August - stalemate and prolonged trench warfare - was likely from the outset.


The vastly increased lethality of both direct and indirect fire, and the increased logistical capacity to sustain it, meant that without a similar increase in tactical mobility (armored vehicles, aircraft) and speed of communication (tactical radio) the ability of any attack to produce a large enough, sustained enough, and damaging enough breakthrough to completely destroy a modern army was diminished to the point of near-nullity, as the Western Front demonstrated for the following four-odd years.

Add to that the problems inherent in the German "strong right wing" plan; van Creveld and  Liddell-Hart weren't wrong. 

The conditions on the ground, and the military technologies, of 1914 meant that it would have required several fortuitous, linked events - a linkage that the "friction" of war (drink!) made something between highly improbable to damn near impossible - going Germany's way to have resulted in the decisive envelopment that the generation of Schleiffen and Moltke had anticipated.

Instead we got the result of the actual August 1914 that set in motion the Western Front of World War 1 and all the changes and consequences that come from it down to our present day.

Among the military changes were several involving "reconnaissance".

Perhaps the single biggest - certainly to the minds of the military planners and commanders of the 1914 generation - of these was the final separation of cavalry and ground reconnaissance, or, indeed, of ground troops in general as the primary element of reconnaissance altogether. Above the purely local tactical level, anyway.

Armies of 1915 and later would still use infantry patrols, and, after the development of practical armored vehicles, light armored/mounted recon units, to learn about nearby enemy positions, strengths, and activities.

But field intelligence above the grand tactical level now meant aerial (and, today, satellite) eyes-on. Which, in turn, meant a progression of reconnaissance and counter-reconnaissance developments; better observation aircraft and tools such as aerial cameras, then counter-reconnaissance aircraft ("pursuit" or "fighter") to keep the enemy's aircraft out, then counter-fighter-fighters - escorts or sweeps - to clear those skies for the recon birds.

Better AAA defenses. Radar. Better aircraft. Better radar. Even better aircraft.

Satellites. Computers. And so on and on.

At least one thing hasn't changed, however.

All the people who led their nations, and armies, into war in the late summer of 1914 believed they could "win". That armed force, military power, would bring material benefits to their nation. Increased wealth. More economic and political power. 

More "happiness", if you will, if by that you mean more of the things that they, and the people of the nations they led, wanted and believed would make their lives better in some form, whether material, emotional, political, or spiritual.

All of them were wrong.

Catastrophically, horrifically, appallingly wrong.

Not just in beginning the years of war they set in immediate train, but in everything that cascaded down from there; the chaotic post-war disasters in eastern and southern Europe that followed the devolution of Austria-Hungary, Germany, and Russia, the inevitability of the brutal Soviet, Nazi, and Italian Fascist dictatorships (and all the other little dictators in places like the Balkans and Spain). Wars, rumors of wars, deaths, starvation, depression and inflation, disease and epidemic, every conceivable human misery.

All of it, all that unhappiness, because the political and military leaders and peoples of that last summer of the Long Peace couldn't not believe that "war works". 

That there were, indeed, "good wars and bad peace".

That hasn't changed a bit.

Every war, every rebellion, every armed conflict ever begun was, and is, begun because the people who began, or will begin, them believed with all their hearts that those wars will "work" and will get them what they think they want.

They have no thoughts of "unintended consequences", although those consequences are inevitable and inescapable and follow every war as surely as night follows the day. 


Perhaps the best exposition of how utterly ruinous their collective delusions were comes from the pen of G. M. Fraser, in the words he puts in the mouth of his character Harry Flashman, from the novel Mister American:

 "Mr. Franklin replied noncommittally, and asked the General what he thought of the war situation. The old man shrugged.

"Contemptible - but of course it always is. We should stay out, and to hell with Belgium. After all, it's stretching things to say we're committed to 'em, and we'd be doing 'em a favor - and the Frogs, too."

"By not protecting them, you mean? I don't quite see that."

"You wouldn't - because like most idiots you think of war as being between states - colored blobs on the map. You think if we can keep Belgium green, or whatever color it is, instead of Prussian blue, then hurrah for everyone. But war ain't between colored blobs - it's between people. You know what people are, I suppose - chaps in trousers, and women in skirts, and kids in small clothes."

The General took a pull at his wine and grimaced. "I wish to God that someone would tell the Hungarians that their wine would be greatly improved if they didn't eat the grapes first. Anyway, imagine yourself a Belgian - in Liege, say. Along come the Prussians and invade you. What about it? A few cars commandeered, a shop or two looted, half a dozen girls knocked up, a provost marshal installed, and the storm's passed. Fierce fighting with the Frogs, who squeal like hell because Britain refuses to help, the Germans reach Paris, peace concluded, and that's that."

"And there you are, getting on with your garden in Liege. But..." - the General wagged a bony finger - "...suppose Britain helps, sends forces to aid little Belgium - and the Frogs - against the Teuton horde? What then? Belgian resistance is stiffened, the Frogs manage to stop the invaders, a hell of a war is waged all over Belgium and northeast France, and after God knows how much slaughter and destruction the Germans are beat - or not, as the case may be. How's Liege doing? I'll tell you - it's a bloody shambles. You're lying mangled in your cabbage patch, your wife's had her legs blown off, your daughters have been raped, and your house is a mass of rubble. You're a lot better off for British intervention, ain't you?" He sat back, grinning sardonically.

(There's a bit more of this discussion, which, if you like, is well worth reading and not just for this bit. It's a fun book in a lot of ways, and worth a look if you can find a copy, long out of print as it is. Anyway, our author has his spokesman conclude...)

He drowned this wistful reminiscence with a hearty gulp of wine, shuddered with distaste, and went on: "I'd also like to remind our jingo-drunk public that they haven't the least notion what a war with modern weapons will be like and the only fellows who can even guess are your American survivors from places like Antietam and Shiloh - that's the only real war that's been in a hundred years."

The General pointed an accusing spoon at Mr. Franklin. "Know how many men went down at Gettysburg? Fifty thousand - and if I hadn't moved damned lively I'd have been one of 'em. Well, how many Gettysburgs d'you think it will take to settle a scrap between the kind of forces under arms in Europe today? I don't know - perhaps a month of it would make everyone cry quits, but knowing the sort of clowns who'll be in command - who are always in command - I take leave to doubt it." 

The ironic part of this little sermon, and what moves it from cynicism to genuine tragedy, is that those in command, in the palaces and the ministries and the field headquarters, were not clowns. They were, for the most part, serious, learned, accomplished, well-intentioned men who genuinely wanted and hoped and tried what they thought was the best for what they thought of as their nations and peoples.

And they were wrong.

Wrong about cavalry. Wrong about aviation. Wrong about reconnaissance. 

Wrong about technology, tactics, strategies, casualties, logistics, politics, economics. Wrong about war, and, through that, wrong about everything that came from it and, through their mistakes and misconceptions then, created so much of what is wrong in our today.

Decisive Battles: Frontiers 1914 - Part 6b: The Crisis (Flanders)

First, I apologize for the long delay. 

I have no excuse except laziness and the appalling condition of my nation and its government; I've just been too angry and frustrated and depressed watching the fucking MAGANazis speed-run 1933-1939 in the so-called "Land of the Free".


I haven't felt much like discussing battles long ago when I felt more like we should be fighting Confederate scum here and now.

But.

I do want to wrap up the "Frontiers" series before the New Year 2027, and we're at the critical point in the narrative, the collision of the Imperial German right - the "strong right wing" of Schlieffen dreaming - and the Franco-British left in the lowland areas between the Ardennes and the Channel.


The last time we discussed the actions along the French frontier was back in July (Part 6a), when we went over the events that too place in the "central" (Ardennes) and "southeastern" (Lorraine) parts of the front.

Before that we digressed to discuss SIGINT (Part 5c) and then went back to addressing the initial meeting engagements (Part 5b) in May. 

We went over the "Opening Moves" of early August 1914 (Part 5a) in February 2025. 

Two years ago we talked about aerial reconnaissance assets and organization in November 2024 (Part 4b) and ground reconnaissance (mostly cavalry, since the much larger range and lethality of direct fire weapon had made the "light infantry" effectively nothing more than a local patrolling asset) in September (Part 4a).

We went over war plans; the French GQG's road to what eventually became "Plan XVII" in August (Part 3) and the German OHL's plan - a derivative of von Schlieffen's 1905 memo that's usually referred to simply as the "Schlieffen Plan" - in July (Part 2), and started the whole thing off earlier in the same month by setting up the geopolitical and military setting of 1914 (Part 1).

Here's where we come to what Frank Zappa would have called the Crux of the Biscuit; the collision of the German "strong right wing" that was the supposed decisive element of the plans that formed the basis of the OHL grand tactical operations in August 1914 with the Allied left, by this time largely composed of the British Army in France, the British Expeditionary Force or BEF, and the northwestern-most French field army, 5re Armee.


Because we've come a ways since we talked about our "forces engaged" we should probably stop and discuss the maneuver elements and - since our thesis here revolves around the successes (and failures) of the various combatant reconnaissance efforts - the organizations and units involved in obtaining the tactical, grand tactical, and even strategic intelligence that, at least in theory, would drive the movement, and engagement, of those maneuver units.

Forces Engaged (western Belgium and northern France): 20-30 AUG, 1914

German Empire (Kaiserliche Deutsches Heer):

The principal maneuver units were the two right-wing armies; 1. Armee and 2.Armee, composed of a total of 24 infantry divisions in 12 armeekorps

(A brief note on terminology: The German term for what the U.S. Army would would call an "Army" (as in 3rd U.S. Army, Georgie Patton's old outfit) was Armeeoberkommando, abbreviated A.O.K. For the purposes of this post to distinguish these "armies" from the overall "German Army" - what in German would have been termed the Heer - we'll use the term "feldarmee", field army. That's not correct per Imperial German usage, but it's easier to remember than A.O.K. - which sounds like something Major Kong would say - or Armee, which is way too much like the French term for field army. It's my fault, and if you want to slap me upside the head for it I'm okay with that.) 

Since we're focused in reconnaissance, each of the major units is listed with the aviation units assigned to it.

1.Feldarmee: 12 Feldfliegerabteilung (FFA)
II Armeekorps (II.AK); 20FFA, 3ID, 4ID
III.AK; 7FFA, 5ID, 6ID
IV.AK; 9FFA, 7ID, 8ID
IX.AK; 11FFA, 17ID, 18ID
III.Reserve-Korps (III.RK); 5RD, 6RD
IV.RK; 7RD, 22RD

Couple of notes here for the German armies:

1. As we discussed in the "aviation" post in this series, a typical FFA fielded six operational aircraft. Typically one FFA was assigned directly to the feldarmee, and one was assigned to each subordinate active armeekorps.

2. However, the reserve-korps, presumably because of their lack of familiarity with the fliegertruppen, were not assigned an aviation unit.

2.Feldarmee: 23 FFA
Gardekorps; 1FFA, 1GD, 2GD
VII.AK; 18 FFA, 13ID, 14ID
X.AK; 21 FFA, 19ID, 20ID
Garde RK; 3GD, 1GRD
VII.RK; 13RD, 14RD
X.RK; 2GRD, 19RD

Notes for 2.Feldarmee:

1. So far as I can tell the "Guard" designation did not mean a significantly better-quality unit. As with most "royal" militaries the Guard got first pick of equipment and recruits, and, presumably, more money for training. In the 19th Century and earlier this likely translated into notably better combat performance by individual Guards units, but by 1914 I suspect that the difference in quality between a regular "Guard" division and a regular line infantry division was pretty marginal.

2. The "2. Garde-Reserve-Division" was an oddball outfit; despite the name only one regiment of the four-line-battalions-plus-a-jager-battalion was formed from pre-1914 guardsmen. That's why it was thrown into a reserve armeekorps.


Army Cavalry:
The German right wing ground reconnaissance was the primary responsibility of one of the Höhere Kavallerie-Kommando (HKK) units, in this case HKK 2, composed of three kavalrie-division (KD); 2KD, 4KD, and 9KD. HKK 2 also contained seven battalions of infantry, specifically jager "light infantry". As we noted in the earlier post, this added significant direct fire strength to the German cavalry corps.

The HKKs were directly under the Imperial Army flagpole, assigned to the Army HQ, Oberste Heersleitung (OHL). In practice they were opconned to the field army commander they were tasked to support, so in this case largely GEN von Kluck of 1. Feldarmee. Later in the campaign HKK 1, tasked to support 3. Feldarmee, turned up adjacent to the French 5eme Armee, but until then von Bulow's 2. Feldarmee had only the divisional cavalry which - as noted below - was not much more than a local recon force.

Interestingly, OHL did not assign aviation units to any of these cavalry corps. Presumably this was because the horse soldiers were supposed to be the "recon" element itself, but you have to wonder whether the fliers would have been useful scouting ahead of the horse soldiers.

It's also worth noting that per the Imperial MTO&E each infantry division had an assigned cavalry regiment. So far as I can tell these units were typically used for purely local reconnaissance and security; the overall grand tactical and operational intelligence gathering function depended on the HKKs and the FFAs.

So two field armies, one cavalry corps, 9 aviation detachments; something like 580,000 troops in the two feldarmees and 22,000 in HKK 2, with about 54 aircraft. By late August this would have included some of 3. Feldarmee's 180,000 troops as well as HKK 1's 13,000.

Third French Republic (Armée de terre, Troisième République Française):

The main force that GQG deployed to met the German right wing was the Fifth Army, 5re Armee, under GEN Lanrezac. Five corps, each of two infantry divisions (division d'infantrie, DI) plus corps and army troops.

5re Armee:
1er Corps d'Armée (ICdA); 1DI, 2DI
II CdA; 3DI, 4DI
III CdA: 5DI, 6DI
X CdA; 19DI, 20DI
XI CdA; 21DI, 22DI

Army troops included two reserve divisions, 52DR and 60DR, and a cavalry division, 4DC.

Aviation (Aéronautique Militaire): Six aviation squadrons (escadrille) were directly attached to 5re Armee; DO 4, DO 6, C.11, N 12, REP 15, and V 24. As we discussed in the "aviation post", these squadrons were authorized six active aircraft each, and the abbreviation before the squadron number indicated the aircraft type; Dorand DO-1 two-seat biplanes for Escadrilles 4 and 6, Caudron G.3 single-seat biplanes in Escadrille 11 (the only squadron flying this aircraft in 1914), Nieuport VI.M monoplanes in Escadrille 12 (also the only French squadron outfitted with this type**), REP Type N two-seat monoplanes for Escadrille 15, and Voison L two-seat pusher biplanes in Escadrille 24.

**(Note - I can't find a definite answer to the complement of the Nieuport VI M. The earlier civilian version (VI G) is supposed to have had a capacity for three; pilot and two passengers. This could easily have been adapted to a pilot-observer two-seat configuration for wartime service, and several sites imply this was the case but I can't find any online source that definitively states the service crew.).


Army Cavalry:
We'll talk about this in some detail when we get to the engagement narrative, but the Franco-British left wing included the only true "strategic cavalry" force on the Allied strength, the French 1er Corps d' Cavalrie (1CdC), usually and better known as "Sordet's Cavalry Corps" after its commander, Général de Division Andre Sordet. 

At the beginning of the last phase of the Battle of Frontiers 1CdC consisted of three cavalry divisions, 1DC, 3DC, and 5DC, originally probably about 5-6,000 troops each (including engineers, bicycle troops, and horse artillery) so about 15,000-18,000 for the corps but by the third week in August 1CdC was suffering badly from hard marching, poor resupply and maintenance, and attrition.

The unit was bolstered by the attachment of an infantry brigade around the time of the Battle of the Sambre (21 AUG).

So roughly one field army, 300,000 troops in 5re Armee, and another 15,000-odd in 1CdC, a total of 36 active aircraft of varying types, notionally under the overall control of GEN Joffre' of GQG, but, as we'll see, with some fairly significant command-and-control issues.

Great Britain (British Expeditionary Force):

The "contemptible little army"*** that landed at Le Havre between 7 and 16 AUG comprised the bulk of the professional Royal Army then serving in the Home Islands; four infantry divisions in two corps and a single cavalry division.

The two infantry corps amassed roughly 40,000 all arms each and the cavalry came to roughly 10,000, so about 90,000 total. With army troops, aviation assets, ash and trash thrown in it all probably added up to something like 100,000 or so, which as you can tell, really was "little" by continental standards.

Army aviation: Four squadrons (#2, 3, 4, and 5) of 12 active aircraft each, mostly B.E. 2a and Farman F.20 two-seat biplanes, along with a smattering of Bleriot XI single-seat monoplanes and Avro 504 two-seat biplanes. All assigned directly to BEF HQ.

So about 100,000 all arms, and about 48 aircraft, under the command of Field Marshal Sir John French.

***(Note -  I've heard that term - "contemptible little army" - ever since I first learned anything about the Great War. It was attributed to some sort of public statement from Emperor Wilhelm II, with the caveat that supposedly the original wording was something like "...verächtlich klein..." which can be translated either as "contemptible little" or "contemptibly little", and that the German wording was intended to mean the latter and that British propagandists twisted it to read the former so as to insult the BEF and by inference the British in general.

Well.  

Apparently there is no "original German". Here's a long thread on the "Great War Forum" discussing the lack of any sort of German source despite over a century of investigation. So, no. Kaiser Bill (and no one else in Germany) called the BEF "contemptible", small or otherwise. It is British propaganda, pure and simple.)

Together the Allied totals were about 400,000 main force (5re Armee and the BEF's I and II Corps) troops, about 15,000 "strategic" cavalry, and about 80 aircraft against Germany's two (and, later, a third) feldarmee (about 580,000 all arms) and parts of two "strategic" (HKK) cavalry corps (probably about 25,000-odd including jager infantry) and 54-odd aircraft.

Now that we've got these two forces coming together along the Franco-Belgian border, to figure out where our reconnaissance elements fit in we need to discuss...


What were the opponents trying to do, and how was reconnaissance important to the success of each side's operations?

Germany: Remember we're out at the far right hand of the big swing around the French Séré de Rivières fortress line, the "strong right wing". The idea that had been presented, in Schlieffen's 1905 memo anyway, was to swing wide outside - west - of the end of the French (now including British) main forces defending the frontiers (and, presumably, attacking in Alsace and Lorraine) to get in behind the Allied armies.

Once between the Allied main line of resistance and the lines of supply and communication, largely running southwest towards Paris, the right wing could envelop and cut off the Allied defenses, much as the French armies of 1870 had been encircled at Sedan, and, presumably, cause a similarly speedy collapse and capitulation...before the Russian armies could fully mobilize and attack East Prussia in strength.

To do this OHL needed to know:

1. Where were the left-side Allied forces? And, in particular,

2. Where was the far-left-end of the Allied line (so as to know how much further west to go to loop around it)?

One thing that Schlieffen had added in his memo that he considered an important part of #2 was the need to cut off and destroy, or at least neutralize, the Belgian Army...meaning that there was a third somewhat secondary task,

3. Where were the Belgians? Specifically, find and crush them before they could fort up in Antwerp and force the right wing to divert troops to form a covering force there.  

That was pretty much it; find the far left end of the Allied line (while finding the rest of the Allied forces, mind you...) while keeping an eye on the Belgians.

This meant that at least one of the HKKs - in this case, HKK 2 - should have been sent out west in front of 1. Feldarmee underneath as big a cloud of aircraft as could be spared from searching for the Belgians as well as the French (and British) MLR. Better yet, HKK 1 should have been released from 3. Feldarmee, whose axis of advance was fairly narrow and well-defined as a search corridor. 

Did that happen? 

We'll see in a bit. 


Britain and France:
Kind of the reverse of the German problem. The "enemy's most dangerous course of action" was masking/engaging the Allied left-wing armies to keep the attention of GQG snd the BEF to their front while looping a significantly large force around the outside of the Allied left.

The Allies had to know that their left was pretty much "in the air". The left-most element - the BEF - had nobody to their left outside a fairly thin screen of French reservists and those not really active-reserve-type units, local "territorials", that would be capable of little more than defending in place, if that

The logical place for the cavalry - both Sordet's Corps as well as the BEF's small cavalry division - as well as the bulk of the RFC  and French aviation assets - would therefore be spun out to the north and west of the Allied MLR to find and report any German activity there. 

All the while sending local cavalry/aviation patrols out to the north and east to find the advance elements of the German main forces, mind. I'm not saying this was easy in execution, just simple in concept. 

(Insert Clausewitz's (drink!) observation about simple things in war here...)

Again, we'll see what actually happened in a bit.

Situation - 17 AUG 1914:

We'll start on the 17th because the last of the Liege forts capitulated on 16 AUG, freeing the right wing armies to drive west past the Meuse into the central Belgian plain.


The Belgian Army had dropped behind the line of the river Gete, outnumbered and outclassed by the German troops now approaching from the east. The Belgian command knew this, and didn't intend to die in place, given that their new Franco-British allies could offer little or no help.

On 17 AUG the 1. Feldarmee air and cavalry recon efforts had done well to locate the Belgian main line of resistance; Bowden (2017) cites the OHL orders on that date as identifying the MLR as "Diest-Tirlemont-Wavre" which was pretty close to correct (the Belgian right didn't quite extend quite as far south as Wavre).

This order directed 1. Feldarmee (and HKK 2) conform to the direction of 2. Feldarmee in order to "...drive the enemy troops...back from Antwerp, while covering on our left flank toward Namur."

This is where the first problems confronting the German right wing emerged, and they were operational, not because of reconnaissance or intelligence failures.

Remember, the "problem" the dinky little Belgian Army presented was just in being. If it was allowed to evade envelopment and capitulation by - as the 17 AUG OHL order noted - skipping back and north to Antwerp, it would be in position to make trouble for German rear areas and lines of supply and communications and force detachment of some body of German troops to mask it.


To prevent this the 1. Feldarmee staff (specifically the Stabschef, MG von Kuhl) proposed driving his army directly forward to engage the Belgians to tie them in place.

This worried the 2. Feldarmee command and staff; GEN Bulow directed 1. Feldarmee to detach one corps (II. Armekorps) to swing wide to the north to turn the Belgian left before the body of 1. Feldarmee went in to attack on 18 AUG.

Von Kuhl went off; the proposed maneuver would be too slow and too obvious. The Belgians would see it coming and grab a hat for Antwerp, the very thing OHL didn't want. 

No joy; Bulow insisted on the move, the unit ordered to swing wide, II. AK, got bogged in bad wet ground and was spotted there by Belgian cavalry scouts, and the Belgian Army march-ordered before the end of the day 18 AUG.

Situation - 18 AUG 1914:

So here we are, with the Belgians skating away to the northwest while the three German right-wing armies push directly west. The BEF is still assembling near Le Cateau off-map to the west.

Note the deployment of the German reconnaissance elements, though,

Aviation was directed entirely at the Belgian retreat (though supposedly 3. Feldarmee sent some of its FFA patrols out west and southwest, but not far enough to find the French 4eme and 5re Armee (and missing the French 1 CdC (Sordet) out in front of 2. Feldarmee). OHL, and the field army command and staff, didn't throw any air assets far enough out to the southwest and west to find where the left end of the Allied main force elements were.

The three cavalry divisions of HKK 2 were spread out all over the advancing German armies but were tucked in too close to the infantry; 2te Kavalrie Division (KD) on the right flank of 1. Feldarmee, largely to keep an eye on the Belgians, while 4te KD and 9te KD were too close to the German infantry columns of 2. Feldarmee to do more than skirmish with Sordet's retreating troopers. The entirety of HKK 1 was trying to work it's way forward through the clogged roads behind 2. Feldarmee.

Neither of the HKKs, the supposed "strategic cavalry" of the German right wing, were where they could be most useful, finding the positions of the Allies outfits most dangerous to the right wing sweep, 5re Armee and the BEF.

The German aviation units were doing their rather limited assignments well. Where the French aviators were I have no idea, but their contributions, if at all, seem to have been of limited usefulness; GQG still didn't seem to have grasped what was going on to their north, northwest, and northeast front. 


Situation - 19 AUG 1914:

The biggest difference in the overall conditions was the arrival of the first British maneuver units, and operational squadrons of the RFC, into their assembly areas around Maubeuge.

The British aviators flew patrols to the north as far as Brussels and northeast as far as Gembloux. The Roads to the Great War site has a nice post that provides narratives from the pilot and observer of one of the aircraft that helps us understand one of the technical troubles that made 1914 aerial reconnaissance so difficult:

"First reconnaissance, with Mapplebeck. Lost myself most thoroughly. Landed at Tournai, where I had lunch with the governor and again at Courtrai, where I was taken for a German, until rescued by the Irish inhabitants. Finally achieved my task and returned after six and a quarter hours flying."

On the other side of the hill, 1. Feldarmee's air tasking order sent aircraft from  FFA 12 (under the field army flagpole) patrolling southwest to Namur and from there northwest to Ostend along the Channel coast and from there looping back to Bruges...where another hazard of early military aviation showed up; the pilot overshot the Dutch border, ran out of fuel, and was interned after a successful dead-stick landing.

HKK 2's three cavalry divisions were still trying to fight their way out front; 2KD to the north of 1.Feldarmee, 4KD and 9KD out front of 2. Feldarmee; none of them were in position to make contact with French infantry, though Sordet's cavalry corps withdrew before the latter two KD's towards Gembloux.

2. Feldarmee's cavalry and aviation assets were employed close to the army's own FLOT; fortunately for OHL 3. Feldarmee's fliers were searching out to the west along the Meuse, where their reports placed several French heavy units, including several 5re Armee corps in the area.

This, in turn, produced several directives from the OHL staff:

2. and 3. Feldarmee were ordered to close up around Namur (which would be enveloped and besieged as Liege had been) to attack the French lines along the Sambre to the west and the Meuse to the south of the fortress city.

1. Feldarmee was tasked to continue moving west but, because the west end of the Allied MLR (particularly the BEF) hadn't been located, the army was forced to slow it's movements and refuse it's flanks ("echelon" the left and right flank units) in case the British turned up unexpectedly.

Finally realizing that the critical task of finding the BEF and the west end of the Allied MLR was understaffed OHL ordered HKK 1 released from 3. and 4. Feldarmee control to slide to the right to the north bank of the Meuse and operational control of 2. Feldarmee when it arrived.

Again, the German fliegertruppe seems to have been doing the best of the recon units. 

Neither side's "strategic cavalry" was well-employed (Sordet because his earlier anabasis had wrecked many of the 1CdC's horses and crippled it's mobility as well as neglect by GQG that often seemed ignorant of where Sordet's troopers were, the HKKs because of poor tactical positioning and similar issues with the pace of movement versus the endurance of the mounts; many German cavalry units reported problems with supply, too, including fodder and remounts. 

Remember, the HKKs were "Army" assets, so their logistical support didn't come from the closest major command - the feldarmees - but all the way from OHL to the east. Meaning "meager at best or not at all").


The Allied aviators were doing...something. The BEF/RFC seems to have had the right ideas but was struggling with navigation. Where the Armee de l'Air was, I have no idea. Whatever the activities, the result was that the Allied decision-making was brutally hampered by a lack of strategic information. GQG and Joffre were stuck in the pre-war Plan XVII mindset. As Stewart (1967) lays out;

"...despite the...intelligence appraisal of August 18th suggesting that thirteen to fifteen German army corps were engaged in Belgium, Joffre still held to his plan of attacking Neufchateau with his Third and Fourth Armies.

He both underestimated the size of the German forces engaged and was unduly overconfident that the British Expeditionary Force would arrive in time to contain the northernmost German elements."

Situation - 20 AUG 1914:

At this point the lack of strategic intelligence - on both sides - began to show effects on the western ends of both the combatants' maneuver forces.

On the German right, separation between the left flank units of 1. Feldarmee (still moving mostly westward trying to find the end of the Allied lines) and the right wing of 2. Feldarmee (beginning to pivot south around Namur to find and attack the French 5re Armee reported to be nearing the Sambre) was increasing.

The failure of German reconnaissance units to locate the BEF was largely responsible; until 1. Feldarmee could be sure that the British weren't out there to the west somewhere Kluck had to hedge his bets, casting eyes out to his right and right rear rather than closing up on Bulow's right. 

Further east 3. Feldarmee was lagging behind schedule, hindered by bad roads and congestion.

The strategic cavalry units were still fighting to get through the logistical mess on the Belgian roads. HKK 2 was finally clear of the infantry and artillery columns, but just barely, and spread out all over hell's half acre; 2 KD looping around northwest of Brussels, while 4 KD and 9 KD were moving north and west past the Sambre with the intent to reform the corps somewhere northwest of Mons.

HKK 1 was still trapped in the traffic behind 2. Feldarmee's maneuver forces. 

1. Feldarmee's fliegertruppe were still largely shadowing the Belgian retreat to Antwerp, while 2. Feldarmee's fliers were mostly patrolling the immediate front of the army's advance outside a single flight by FFA 21 (attached to 2. Feldarmee's X Armeekorps) that scouted the Belgian coast.

One bright spot was the work of 3. Feldarmee's fliers, who spotted "...trenches, artillery batteries, and bivouacs near Onhaye..." (Bowden, 2017) along the Meuse. 

But without understanding of the larger Allied deployment - that is, lacking the whereabouts of the BEF and the Allied movements west of the Sambre/Meuse confluence -  OHL was issuing orders based on a conviction that the area south and west of Namur would be the location of the decisive enveloping engagement. 

That area, Moltke believed, would be where the "strong right wing" won - or lost - the war.


The lack of solid reconnaissance and intelligence-collection
on the German right wing meant that the German overall command - OHL - took the absence of evidence of the British out to the west as evidence of absence.

The 1. Feldarmee commander von Kluck worried that the British were out there somewhere. Kluck wanted to keep moving west and southwest to find the BEF and envelop them and the Allied left.

Moltke at OHL was more concerned about the developing contacts along (as we'll see below) the Sambre and Meuse, between 2. and 3. Feldarmee and the French 5th Armee

Kluck kept bugging OHL about moving west, OHL kept insisting Kluck's 1. Feldarmee slide south and east to cover 2. Feldarmee's right because Moltke - in perhaps what was the beginning of his descent into physical and emotional breakdown that would lead to his relief in September - seemed fixated on the enemies he knew about rather than the ones he didn't.

On the Allied left 5re Armee was pushing forward to the junction of the Sambre and Meuse, but the BEF was a godless stramash, columns of II Corps pushing slowly north of Maubeuge towards the "Canal du Centre" north of Mons while the 1 Corps was still strung out around Maubeuge behind them. 

The British cavalry division had moved north and east into the significant gap between II Corps and Lanrezac's leftmost corps (18 Corps d'armee) as Sordet's 1CdC drifted back, first to the open country between the BEF and 5re Armee, and from there into the rear areas behind the British and French forward infantry lines.


Allied reconnaissance failures
 included technical and tactical problems similar to those hampering the German aviators and cavalrymen, although particularly worsened on the ground by the combination of poor tactical and logistical planning, command and control that meant that Sordet's cavalry corps - the only true "strategic" Allied cavalry - was by this point utterly ineffective as anything beyond a local recon and security unit because of its aimless wanderings across Belgium and northern France as well as criminally inadequate C3I by its nominal "commander" Joffre at GQG. 

The British cavalry is said to have been poorly employed, as well. Terence Zuber is particularly scathing;

"In reconnaissance, counter-reconnaissance and rear-guard operations the British cavalry from 21 to 27 August was utterly ineffectual. Whether the British cavalry was superior fighting dismounted...is a moot point, because it didn’t fight dismounted, but made a practice of withdrawing before the Germans could make contact. Compared to the 2nd Cavalry Brigade fiasco at Audregnies, the Light Brigade’s charge at Balaclava was a signal success – at least some of the Light Brigade got to the Russian guns."

Keep in mind that Zuber's relentless admiration for German tactical training makes him a somewhat unreliable narrator. But the overall performance of the British cavalry in August 1914 makes his general point - that the BEF's commander French was badly served by his cavalry relative to the support the German cavalry gave their maneuver commanders - difficult to refute.

The British aerial recon efforts were, as we noted, hampered significantly by the difficulty of navigating above an unfamiliar landscape and the inexperience of the fliers. What the hell the French aviation units were doing I can't tell...but the difficulty with blaming the Allied aviation efforts is that when both Joffre at GQG and French at BEF were correctly informed of German activity they often disregarded that intelligence in favor of their own prejudices, hopes, or fears.


Summary of Operations, 20 AUG 1914:
It was this day that the real "crisis" of the western portion of the "Battle of the Frontiers" began to develop.

At 1430hrs OHL sent a message to the three right wing feldarmee commanders that read, in part:

"Both army headquarters (1. and 2. Feldarmee) must reach agreements to synchronize the imminent attack against the enemy west of Namur (principally 5re Armee) with Third Army's attack on the Meuse between Namur and Givet." (italics mine)

This, in turn, would shape the coming engagements between the French and British on the Allied left and the Imperial right wing, as we will see.


Situation - 21 AUG 1914: 
Several events, some by design, some by accident, made this and the following day something of a pause in operations. This is also typically considered the first day of the three-day engagement that is called the Battle of Charleroi

(I should note here that for the following several days I will use the wonderful tactical maps provided by Bowden (2017) to orient the descriptions of the actions of both the maneuver and reconnaissance elements.)

So the "story" of 21 AUG was the collision between what everyone planned, and what actually happened. 

The German Plan: OHL's thinking was that:
1) 1. and 2. Feldarmee would close up the gap between them and move south towards the Sambre, with 1.Feldarmee shuffling to it's left while continuing to refuse it's right just in case the damn Brits turned up to the west, but wouldn't engage the French defenses along the river lines.
2) 3. Feldarmee would complete it's advance to the Meuse.
3) HKK 1 would finally cut itself loose from opcon of 3. and 4. Feldarmee and loop around Namur where it would begin recon for 2. Feldarmee

The French Plan: as envisioned by GQG, was...
1) That 5re Armee would move forward to support the main attack of 3eme and 4eme Armee in the Ardennes - remember, Joffre's aggressive Plan XVII was still the overarching grand tactical concept of operations.
2) The BEF would move into line with 5re Armee and then the two would fix the German right with attacks until the Ardennes breakthrough would allow the French armies to pivot left and fall on the lines of communication and supply in Belgium (and the rear areas of the right wing feldarmees.


GEN Lanrezac's caveat
to GQG's offensive focus was based on 1) the slow meandering pace of the BEF's advance, and 2) the delay that GQG had nailed his army in place until late on 16 AUG, meaning that the lead elements of 5re Armee didn't reach the Sambre until 20 AUG.

This meant that Lanrezac had nobody to his left, and that created a terrain problem to his front.

The north bank of the Sambre was better, higher ground than the south.

But without support to the west pushing the bulk of his forces north of the river risked being outflanked and attacked from north and west with a river at his back.

So Lanrezac compromised, sending detachments across the Sambre to fortify the north bridge abutments while digging in the bulk of his army to the south (and refusing one corps to face 3. Feldarmee across the Meuse).


What actually happened:
Instead of pulling up on the north bank of the Sambre, the lead elements of Bulow's 2. Feldarmee - the 2te Garde Infantrie Division of the Imperial Guard - attacked right off the line of march and took the bridge crossing at the town of Auvelais and established a solid bridgehead on the south bank.

Later in the day another 2. Feldarmee infantry division from X Armeekorps did the same further east at Tergne. 

This German aggression bothered GEN Lanrezac not a whit; he'd instructed his corps and division commanders not to fight for the bridgeheads, preferring to dig in deep on the high ground some distance south of the Sambre. 

So, in theory, the actions on 21 AUG should have set up a German attack on French (or Anglo-French, had 1. Feldarmee and the BEF moved more quickly) defensive positions on 22 AUG.

Since, as the military aphorism says, no plan survives contact with the enemy, the reality was somewhat different.


Reconnaissance activities, 21 AUG:
So far as I can tell, these fall into two categories: German aerial reconnaissance, which was extremely successful in one area and largely absent in the rest, and Allied strategic reconnaissance (both air and ground) and German strategic cavalry recon, all of which did very little, and some random British infantry - specifically a bicycle recon unit of the 4th Middlesex Regiment - encountered German 1. Feldarmee cavalry patrols near Obourg north of Mons (which the BEF commander, French, seems to have ignored (see 22 AUG).

Both German HKKs were out of contact all day, HKK 2 ranging out to the west between Tournai and Ath, far from the nearest British units along the Canal de Centre near Mons, and (as we've mentioned) HKK 1 in the process of changing fronts.

The Allied cavalry - both Sordet's 1CdC and the British Cavalry Division - were out of position, behind their own infantry lines; Sordet between and behind 5re Armee's left and the BEF I Corps right, the British in behind their own II Corps.

German aviation did quite well - for 2. Feldarmee. FFA 1 (supporting the Guard corps) and FFA 30 (supporting X.AK) provided accurate intel that helped the attacks across the Sambre succeed. Later in the day all of 2. Feldarmee's fliers were involved in finding and reporting 5re Armee's defenses. 

However, 1. Feldarmee's aviation units seem to have been either unable to find, or unable to report, the whereabouts of the BEF, which contributed to the overall hesitancy of Kluck's army's move to the southeast.

Allied aerial reconnaissance seems to have informed the Allied commanders, from French and Lanrezac at the front up to Joffre at GQG, of German activities, locations, or strengths (as we'll see in just a bit...) but the information seems to have been incomplete, or possibly poorly understood. This wasn't really as much a problem as it could have been - Lanrezac pretty much knew where his enemies were coming from and French did but was too scatter-assed to benefit from that - but it added to the overall lack of focus and understanding at GQG.


Situation - 22 AUG 1914:

The "big story" of this day was the damn French infantry commanders screwing the pooch again as the Battle of Charleroi continued.


Here's how Bowden (2017) describes it:

"Lanrezac's corps commanders...expressed their intentions in their nightly reports of the 21st-22nd to order an immediate counterattack at dawn to reclaim the lost bridges. Despite vehemently disagreeing, Lanrezac felt it was too late in the evening to countermand his subordinates' orders before the attacks would begin."

The French corps commanders compounded their grand tactical incompetence with tactical clusterfuckery; their cunning plan was to try and "surprise" the German south-bank bridgeheads by a mass infantry rush, having not bothered to ascertain that the Gardekorps and X. Armeekorps defenses had been dug in and wired hard overnight and were well supported by artillery.

Predictably the French infantry was butchered.

And, equally predictably, the French infantry officers refused to accept defeat, instead bringing up their own artillery to try and shoot more infantry into the German defenses.

That failed, too.

Instead, 2. Feldarmee's armeekorps pushed out of their defenses and drove back the decimated French II and X corps d'armee, leaving Lanrezac's main line of resistance further south and in poorer ground than that he'd originally planned to defend.

Well, sod that for a game of soldiers.

Meanwhile, 3. Feldarmee was dragging ass, so OHL ordered 1. and 2. Feldarmee to hold in place, wait for their buddies to show up, and make a general attack along the Meuse/Sambre/Mons line on 23 AUG.


Reconnaissance activities, 22 AUG:
It's worth noting that, as is often the case, reconnaissance intelligence is only as valuable as the degree to which the receiving commander(s) credit it. Here's a summary of some of the British recon actions that day (from the Wiki article on the Battle of Mons):

"At 6:30 a.m. on 22 August the 4th Royal Irish Dragoons sent two officers' patrols from Obourg northwards towards Soignies and one drove off a German outpost. A troop advanced later and engaged German cavalry advancing south from Soignies towards Mons, repulsing it near Casteau and began a pursuit until stopped by German return-fire. Three to four German cavalry were killed and three taken prisoner from the 4th Cuirassiers of the 9th Cavalry Division (9KD was part of HKK 2, remember?). That day, having used British reconnaissance aircraft along with Lanrezac's messaging to his army staff, the BEF's chief of intelligence, Colonel George Macdonough, warned (Field Marshal) French that three German corps were advancing towards the BEF. French chose to ignore these claims, instead proposing to advance towards Soignies."

Yeah, well, there's a reason that French has been roundly spanked by many soldiers and historians familiar with his work in August 1914.


German aviation and cavalry
were doing hard work; HKK 2 was (as noted in the citation above) feeling out the BEF's positions along the canal near Mons (HKK 1 was still slogging around the besieged fortress of Namur). 2. Feldarmee's flying sections picked up the French counterattacks early and reported French movements and strengths in detail throughout the day.

Per Showalter (2019) Kluck at 1. Feldarmee was still worried about Brits popping up on his right:

"Focusing on the Lille expectation, all of the aviation assets of First Army were sent in that direction...(except) the flying section of Ninth Army Corps...(t)hat...was assigned to the area around Mons. All of these aviation elements reported negative contact with the BEF". 

This absence of evidence should have been broken both by 9KD's contact along with a patrol from FFA 11 (the IX Armeekorps feldfliegerabteilung mentioned above) that reported encountering formed troops as well as vehicles - trucks and wagons - on the roads leading toward Mons and the nearby centers of Bavai and Binche.


It didn't. Bowden (2017) doesn't mention this, but Showalter (2019) - whose thesis is that "reconnaissance failure" helped derail the German plans in 1914, remember - reports that this patrol report was somehow lost in transit and never reached Kluck's headquarters, reminding us that "...the intelligence section officers (Ic) of the German army corps...were heavily overworked and didn't forward an estimated fifty percent of the aviation reports to First Army."

Showalter (2019) goes into some depth about disagreement at the feldarmee-and-above command level that made the 1.Feldarmee recon situation worse, but we'll get to that when the morning of the next day dawns.

Situation - 23 AUG 1914: The Battle of Mons and the final day of the Battle of Charleroi.

The maneuver elements of both sides - BEF and 5re Armee for the Allies, all three German right wing feldarmee - get stuck into each other, so the first order of business for the reconnaissance troopers and fliers is tactical support for their infantry and artillery spotting.

And that turns out to be difficult; for the aviators by bad weather (mostly heavy fog in the morning and clouds and stormy weather all day), and the by-now-usual-1914-problem of fighting for intelligence against rifle, machinegun, and artillery fire for the cavalry...with what should have been some significant exceptions, as we'll discuss.


The German attacks
were pretty straightforward. 2. Feldarmee pushed south, either out of it's 21-22 AUG bridgeheads (for the Guard and X. AK) or from the north bank of the Sambre (for VII AK and X RK). 3. Feldarmee across the Meuse against the refused right flank of 5re Armee, and 1. Feldarmee across the Mons canal against the British II Corps. HKK 2 was busy out on the far right end of the German line of advance.

The Allied defense was likewise fairly straightforward; using river lines wherever possible. The two main element commanders' differing tactical abilities complicated things a bit, though.

Lanrezac had reorganized his defenses overnight, shifting units to provide relief for outfits like X CA that had been mauled on 22 AUG as well as to take advantage of good defensive terrain such as that which dominated the west bank of the Meuse.

French, on the other hand, set up the BEF poorly because of his fear of encirclement; his right-hand I Corps was echeloned southeast, useful in case of a 5re Armee collapse but unable to support II Corps along the canal and barely engaged all day.

Much has been written about the actions of 23 AUG, and I'll trust that as a student of military history (or why are you still reading thus far..?) you know most of them. Suffice to say that this time it was the German infantry's turn to experience the "World War 1 infantry attack" horrors of direct and indirect fire while struggling against terrain and man-made defenses such as wire and trenches.


The German attacks succeeded in taking the objectives on the ground at the expected cost in lives, and both 5re Armee and the BEF were forced back but in fairly good order; the elusive breakthrough-and-pursuit result of tactical victory (as all combatant armies would discover over the next four years or so) was unachievable given the constraints of distance, armaments, logistics, and casualties.

But the result was a problem for the Allies; both major commands had lost lives and equipment and control of the most promising defensive terrain, as well as contact with each other. Both Field Marshal French and GEN Lanrezac concluded separately that it was time to grab a hat, and orders for a general withdrawal south were issued on 23 AUG to be effected overnight. 

On the other side of the hill OHL yoicked the three feldarmee forward.


Reconnaissance activities, 23 AUG:
 The fliers on both sides were - when weather permitted - largely committed to tactical reconnaissance and maneuver unit support. 

The British Cavalry Division was pulling left flank security for the BEF, Sordet's troops still out of contact, and HKK 1 still struggling through the jammed traffic in the 1. Feldarmee rear. 

On the far right end of the German advance, though, reconnaissance, internal communications, and a failure of intelligence analysis were causing problems for the "right wing sweep".

During the day cavalry patrols of HKK 2 were ranging out west of the right wing of 1. Feldarmee. Despite their position, the German horse soldiers were under the control of Bulow's 2. Feldarmee rather then Kluck's HQ, and on 22 AUG Bulow had ordered patrolling to go northwest towards Courtrai to chase an air recon report of British cavalry there.

Kluck and Bulow fought over this; Kluck's troops, in contact, were confident that the aerial reports were wrong, and that HKK 2 was wide of the British left with mostly open country to the south. 

Ground recon reports supported this; forward HKK 2 cavalry patrols as well as infantry contacts along the far right of the 1. Feldarmee advance were finding not British regulars but French reservists, "territorials" between Conde' and Lille, and few of them at best. 

Kluck insisted that HKK 2 push south and west to fight through this thin screen and envelop the BEF left. Bulow and OHL resisted well into the day on 23 AUG before relenting and passing opcon of HKK 2 over to 1. Feldarmee.

By then it was too late. Had the German riders any chance to cut off the retreat from Mons if they'd been moving south on 23 AUG it was gone that evening as the "Great Retreat" had already begun.


Showalter (2019) insists that this was a - or THE - decisive failure of the right wing, quoting several German authors to that conclusion. His own conclusion states that;

"Had HKK 2 swung around into the rear area of the BEF near Mons, World War I might very well have taken a completely different course. Indeed, that result might have been certain."

I'm very much skeptical.

HKK 2, like all the German cavalry, had been marching and fighting for three weeks. The guys were tired, the horses even moreso. The British cavalry, holding down the BEF left, was relatively fresh and unblooded. The likelihood of HKK 2 smashing through into the British rear in strength seems unlikely, the probability of the British regular infantry coming apart in response seems improbable.

I think that had OHL passed control over the German cavalry sooner the fighting on 23 AUG, and the retreat on 24 AUG, might have been much nearer-run things. But changing the course of the war entirely?

Sorry. I don't buy it. 

Situation - 24 AUG 1914: The first day of what would become known as "The Great Retreat".


Now that the Allies were trying to break contact good recon - figuring out how and where the British and French defenders were retreating to cut them off if possible - was essential, and the reconnaissance burden was almost entirely on the German aviation units, the German strategic cavalry being either too far west (HKK 2) or to close to their own infantry (HKK 1).

Here again it seems like the German fliers did a lot of good fieldwork, finding the routes and direction of both the BEF and 5re Armee but, critically, that poor staff work in interpretation and analysis of reporting, screwed up the response on the ground.


On the German right 1. Feldarmee staff reacted to a single FFA 7 report received at 0200 on 24 AUG - which was in direct conflict with observations of all the other aerial patrols during the previous day - and altered the line of advance under the mistaken presumption that the BEF was falling back east/southeast into the fortress lines around the city of Maubeuge rather than south towards Le Cateau.

Meanwhile similarly good aviation scouting had given GEN Hauser and 3. Feldarmee a picture of the situation along 5re Armee's right that suggested a drive from the Meuse crossings southwest might bag a big portion of the French defenders.

But Bulow wasn't convinced. Instead, worried about the potential for disaster if a French counterattack hammered 2. Feldarmee, he ordered 3. Feldarmee to attack directly west.

There they found nothing but the debris of retreat and the silence of empty fields and woods. 

The Allied left - badly beaten and decimated as it was - had escaped.

Situation - 25-26 AUG 1914:  The Great Retreat continued, while OHL and the right wing feldarmees made the right moves too late.

As we discussed above, both Kluck at 1. Feldarmee and Bulow with 2. Feldarmee had made poor choices - and they were choices, not the direct result of misinformation; the aerial reconnaissance was solid overall, but the combination of overwhelmed corps intelligence staff and both army commanders' fixed ideas led them to either ignore the intel or seize on anomalous reports that supported their preconceived ideas - meant that the German armies moved in the wrong directions and the bulk of the French and British units evaded the German moves.

For a day or so; once reports came in from the feldfliegerabteilungen that had located the Allied lines of retreat the German armies came on with a rush.

The French left-flank armies, 5re and 4eme, fell back some 7 to 9 kilometers southwest in decent order. 


The British were a fucking shitshow, and FM French seems to have had either little or no understanding of that and/or little skill to change it had he known. 

II Corps, beat up along Mons canal, had staggered south and west towards Le Cateau through the wooded roads of the Forêt de Mormal. The Cavalry Division moved alongside and west of the infantry and artillery.

I Corps was straggling south along the roads south of the Sambre, several miles east of II Corps because of a combination of the BEF commander's failure to force his subordinates to coordinate their movement and GHQ's perception (not entirely unjustified) that the roads through the forest were too narrow to allow passage for both corps.

25 AUG, the I Corps rearguard was attacked near Landrecies. This force, mostly British foot guard infantry, fought a tough, and successful, little holding action before sloping off south on the morning of 26 AUG.


The fight seems to have shaken I Corps commander, GEN Haig, who fired off a message to GEN Lanrezac so dire that it put the wind up 5re Armee's command and staff. 

Whether or not Haig "panicked" (and historians differ on what happened with I Corps at and after Landrecies) his orders directing I Corps to retreat towards Guise to the south rather than join up with II Corps to the southwest meant that the BEF remained a patchwork shambles through 25 and into 26 AUG, when the other British corps, II, was attacked at Le Cateau.


26 AUG: Clusterfuck at Le Cateau

The commander of II Corps, GEN Smith-Dorrien, seems to have had no intention of fighting there, but his outfit arrived late on 25 AUG and on seeing how exhausted his troops were when their sergeants kicked them out of their blankets on the morning of 26 AUG Smith-Dorrien chose to remain in place around Le Cateau.

The disposition of the II Corps bivouac sites was a hot mess. Infantry were sprawled out on forward slopes, outside of supporting distance of each other, without field fortifications or other obstacles in place. Dead ground was left uncovered and unobserved. Royal Artillery batteries had dropped trails in open ground and often within several hundred meters of their infantry, making both arms big fat targets for the German gunners.


Neither II Corps or the Cavalry Division, or their opposite numbers in 1. Feldarmee, IV Armeekorps, seem to have expected the other to be where they were at Le Cateau, so neither FFA 9 (the IV.AK feldfliegerabteilung) nor the RFC outdid themselves there.

The respective French and German cavalries put in a good day's work, however; the three divisions of HKK 2 formed a large portion of 1. Feldarmee's attacking strength and were effective in dismounted attacks on the left side of the II Corps defense, while the tired troopers of Sordet's 1er Corps d'Cavalrie were rushed southwest to shore up the British left and is credited for ensuring that, when the British resistance eroded, II Corps withdrawal from Le Cateau was effectively covered.

Once the fighting at Le Cateau was underway, and until bad weather - heavy rain and thunderstorms - shut down aerial reconnaissance the German aviators did much better than they had in the leadup to Le Cateau; Bowden (2017) notes that 1. Feldarmee's fliers were effective in finding and detailing movement and direction of both British infantry corps, allowing Kluck's army to continue pursuit the following day.


Situation - 27-28 AUG 1914:
More Great Retreat and the Battle of Guise/St. Quentin.


So far as I can tell the two sides had few issues with reconnaissance or intelligence-collection during the two days following the engagements as Le Cateau/Landrecies, largely because the German forward elements - presumably both cavalry and infantry scouts - maintained contact with the British and French rearguards. The fliegertruppe were still busy, and per Bowden (2017) continued to provide useful information when the weather permitted - storms grounded the fliegerabteilungen several times on 27 and 28 AUG.

But...what did happen was that the three right wing feldarmees followed different axes of advance, the weather sucked as often as not, and German army staff intelligence analyses had some of the same problems we've seen.

On the far right 1. and 2. Feldarmee pursued 5re Armee and the BEF to the southwest.


3. Feldarmee
, however, was torn between that and pursuing the retreating French 4eme Armee to the southeast, opening (as you can see above) a considerable - 15-20 kilometer - gap between the 2. Feldarmee left and 3. Feldarmee right. 2. Feldarmee itself had an almost 12-klick internal break in contact, between the Gardekorps and X. AK on the left and VII. AK and X. RK on the right.

This spooked Bulow. A lot. He kept bugging Hauser over at 3. Feldarmee to skootch right to protect their open flanks. Hauser kept trying, but at the same time 4. Feldarmee was having a tough time with the fantassins of 4eme Armee and was screaming for help, too. On 28 AUG Hauser gave up and shifted to the left to link up with his pal Albrecht and 4. Feldarmee.

What between the weather problems and the general fog of war produced a German intelligence failure during this period - missing the 5re Armee's preparations between 27-28 AUG for a local counterattack on 29 AUG.

This attack was ordered by GQG to 1) take pressure off the BEF, which had been badly mishandled, and 2) buy time for Joffre to pull together the tag-ends of active and reserve units out beyond 1. Feldarmee's right that would become the 6eme Armee of the Marne.

It worked, at the usual gruesome cost.  


Situation - 29-30 AUG 1914:
The Great Retreat continued past the end of the Battle of Frontiers.

The fight at Guise/St. Quentin had bought GQG some time, but had also killed and wounded more of 5re Armee's infantrymen, contributed to the disorganization within the army, and had continued the erosion of trust and confidence between Field Marshal French of the BEF, Joffre at GQG, and 5re Armee's GEN Lanrezac.

(Joffre ended up relieving Lanrezac on 3 SEP 1914).

The Allied forces continued their withdrawal to the eventual positions where what would become known as the First Battle of the Marne began two days later, and the German right wing armies pursued, while failing to close the open country between 1. and 2. Feldarmee, providing a weakened "hinge" for the Anglo-French to target and create panic at OHL. 

This led directly to the resignation of Moltke as Chief of the General Staff, the appointment of Falkenhayn, and from there to the eventual charnel house of Verdun. 

But for the purposes of our inquiry, this ended the "maneuver" fighting that had dominated the beginning of World War 1 that we've called the Battle of the Frontires and began the brutal grind of positional trench war that we've come to think of when we think "World War 1".


Bowden (2017) says:

"...the German War Plan was predicated upon a quick and decisive victory featuring the destruction of a significant portion of the allied armies in the field. Thus, the continuation of the allied withdrawal in the aftermath of the battle was effectively a defeat by postponing another general engagement." 

This is specific to Guise/St. Quentin but much the same can be said for the Flanders portion of the Battle of the Frontiers in general, and to an extent to the entire Western Front in August, 1914.

To win the war Germany needed to largely, or completely, destroy the British and French field armies as they had the French in 1870 and as they did the allied armies in 1940. That didn't happen in August 1914, and some of the reasons for that can be laid to, as our initial hypothesis suggested, problems with the tactics and techniques of reconnaissance gathering.

But only some, and that's what we're going to discuss in the final post in this series. 


Last: The Battle of the Frontiers and the Failures of August 1914
