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 5c (Interlude) SIGINT

 

On the last Frontiers post commentor Carsten reminded me (Thanks, Carstens!) of another August 1914-thing that changed how armies fought; "Signals Intelligence", or in the term the U.S. Army uses, SIGINT.

Now you could say that SIGINT wasn't exactly a new 1914-thing. Enemies had been trying to steal each others' secrets and communications since, well, probably the Late Stone Age. After all, when you know what your enemy is going to do, and when and where, you can be there (or not be there...) sooner, in greater force, and with surprise.

And both battles and campaigns before the 20th Century were affected by the loss (or gain) of communications, obviously in the form of things like written orders. Back in 2008 we discussed the 1862 Battle of Antietam, where the accidental discovery of the Confederate operations orders ("Special Order 191") should have resulted in a crushing U.S. victory.

The big difference between 1862 SIGINT and 1914 SIGINT was the invention of "wireless telegraphy" (principally) by Guglielmo Marconi around 1895.

Of course the use of electrical power - which the new "WT" or "Radio" depended on - to send signals was as old as the mid-19th Century, when the electrical telegraph had replace the "optical" telegraph (stuff like this thing, a signal station with movable panels or arms to send semaphore signals...)...

...and telegraph wires were strung all over the world.

The problem with wires - and all the armies of 1914 still strung and used miles and miles of wire, mind! - were multifarious. First you had to string them, which took people and time, since existing wires often didn't run where the armies needed them.

Then you had to protect them, particularly from artillery fire, which as you can imagine was a very "1914" kind of problem.

And third, the wires literally tied you in place. If you moved away from the existing wires you'd be voiceless and deaf until you reached (or ran) a new set of wires,

So the ideal way to use electricity would be to power some sort of equipment capable of sending and receiving electrical pulses (since that's all the telegraph was; turning "on" the current for a signal, turning it off for a gap or pause) through the air, without the wires.

Marconi did that, building on the work Hertz had done, using a form of electromagnetic radiation; "radio waves".

Here's the thing about those early radio sets, though.

They were big and heavy. They were also fairly fragile, and didn't like rough handling which, as you can imagine, is kind of a "war thing". And they required a steady supply of electricity, meaning if you couldn't just plug into the wall socket (not a "war thing", either) you needed a generator, also big, heavy, and fragile (or two guys riding a stationary bike...


...which is kind of weird when you think of it as "war", but, then, war is fucking weird.)

Which is why the first radio SIGINT was by navies and directed at warships.


Which is where we talked about this in our 2013 discussion of the Scarborough Raid and the activities of the British "Room 40" naval SIGINT people involved.

By the time the first rounds went downrange in 1914 the armies of all the major combatants had radio, though, and were developing their own SIGINT capabilities. The U.S. Naval Institute has a good little summary of early radio warfare, including the drawbacks, including that...

"...its use alone might reveal one’s presence and position to the enemy. (T)he very presence of wireless messages in the air will enable the enemy to guess that something is happening. By the time World War I broke, radio-direction-finders were coming into existence, which would enable the enemy to pinpoint one’s forces."

What didn't help was the crudity of the early radio transmitters:

"(I)n the early days of radio...any time one sent a message over the air, practically any one with a set could pick it up. (W)ith the spark system and the primitive receivers, there was no selectivity of stations...as late as 1914 the equipment in use emitted a signal many kilocycles wide, one signal covering perhaps the whole of the present broadcast band."

To a former GI used to the frequency-hopping sophistication of modern military commo gear that's utterly horrifying, the COMSEC equivalent of adorning your foxhole with flags and streamers and ginormous speakers blaring Bohemian Rhapsody whilst you prance around it in a pink tulle' tutu. 

Why not just paste a sticker on the front of your helmet reading Just Shoot Me Now!?


The SIGINT people of 1914 kind of had to figure this out for themselves, though. 

Famously the German radio intel people were reading Russian e-mails in August that provided extremely useful intelligence about the Russian offensive in East Prussia that led to the thumping win in the Battle of Tannenberg, but as noted in this NSA briefing,

"When the war broke out...there was no fixed organization in either the German or Austrian side for intercepting foreign radio traffic...field regulations for German telegraph troops did foresee the the possibility of listening in...when their own was dormant.

At the time there were two rather large fortress radio stations in eastern Germany which had relatively little traffic of their own and were consequently in a position to listen to the enemy...(e)ntirely on their own initiative a few operators (at the fortresses of Konigsburg and Thorn (Note: this 19th Century fortification was located near the current Polish city of Toruń), and the former civilian station at Breslau) attempted...to listen to Russian army traffic as a sporting proposition, so to speak; it was not long before the first messages were intercepted but no one knew quite what to do with them..."

Fortunately for 8. Feldarmee commander GEN von Hindenburg the fortress CO at Thorn decided to send these intercepts on to Army HQ on his own hook. 



But you get the idea; this was an ad hoc sort of thing for the German Army.

It sounds like the French were a bit better organized. Here's what the WarHistory.org article about SIGINT on the Western Front says:

"The French Deuxième Bureau on the Western Front was well prepared for the signals war...even though they did not have the benefit of the plain text messages that Hindenburg enjoyed reading during his campaign in the east. However, they were able to decipher the German messages quite easily."
Some of the French SIGINT was simplified by sloppiness in German COMSEC brought on by the stress and pace of the "right wing sweep".
"(German 1. Feldarmee commander) Von Kluck’s rapid advance...used radio extensively to co-ordinate the units of his army according to plan. German radio operators...sent transmissions correctly in cipher to begin with, but as the heat of battle increased, messages were sometimes sent in plain text and security procedures began to flag."

Apparently the German Höheres Kavallerie-Kommandos (the HKKs) were the big problem:

"The Cabinet Noir was the cryptographic department of the Deuxième Bureau (French Military Intelligence) and intercepted over 350 radiograms transmitted by the German cavalry corps over a two-week period during the campaign. Radio station staff had no clear instruction on wireless security so the call-signs of each station in the army invariably started with the same letter and remained unchanged as their advance progressed, nor was there any change in wavelength of the broadcasts. 

Cavalry units were the worst offenders, probably due to stress of their fast-moving formations...Each German cavalry control station, for instance, had an identifying letter: ‘S’ was the designation of units in Belgium, ‘G’ in Luxembourg, ‘L’ in the Woëvre and ‘D’ in Lorraine. Confirmation from some messages came in plain text and could even be clearly signed by the sender with their rank and name"

I'm not an intel weenie but even I can figure out that's not good. 

As you can imagine, the Eiffel Tower made a terrific radio listening post

It's difficult for me at this distance to tell how each element affected the course of the Battle of the Frontiers. Certainly reconnaissance and counter-reconnaissance on the ground made differences, both from what the aviators and cavalrymen discovered...and what they probably should have and didn't.

Certainly SIGINT (and it's "opponent", COMSEC) made differences, too. The author of the War History piece certainly thinks that French SIGINT was crucial:

"Von der Marwitz’s cavalry were ordered by radio to provide a thin screen of lancers to cover the widening gap between First and Second armies. The French identified this as a weak spot in the German front that began to stretch for miles as the two armies advanced at an uneven pace. Using signals intelligence gleaned by the Deuxième Bureau on 8 September, the French general struck at the critical point between the two German armies’ line of advance. They soon began to threaten the German First Army with encirclement and outflank von Bulow’s Second Army in the process, causing both German armies to retreat...the German Army retreating in the face of a desperate French resistance became known as ‘The Miracle’ in public parlance. The French High Command and the Deuxième Bureau, however, knew better."

As we'll see in the next several parts, reconnaissance troops on the ground and in the air played a big part in the "Miracle" as well as the engagements leading up to it, so...is there a definitive "answer"?

No. Like much of modern warfare - indeed, like much of warfare, period - the real effects and impacts of all the various factors; physical, emotional, intellectual, as well as things like weather, terrain, organizations and equipment, doctrine...are all related and interacting with each other.

All we can do from a distance is try and tease out how and why each affected the outcomes.

Certainly the radios, both as part of each side's "C3I" (command, control, communications, and intelligence) as well as the SIGINT people's use of them as enemy intelligence sources, played a role. Befitting the relative unfamiliarity all the armies had with radio, though? My guess is that those roles varied significantly, from critical to marginal to overlooked entirely.

Anyway...I thought the SIGINT part of the story was worth discussing. Thanks again, Carstens, and we'll be back later in May with the "big story" of the Frontiers; the critical Battle of the Ardennes that kicked off in the third week of August 1914.

Decisive Battles: Frontiers 1914 - Part 5b: First Encounters

We're a week or so into the Great War - 7 AUG or so - and the German Imperial forces and those of the Republic of France and the Kingdom of Belgium have fought the first encounters of the opening moves of that war, the so-called "Battle of the Frontiers".

Recall in the previous post we divided the timespan of this opening engagement into four parts:
1. "Preparations" (1 AUG - 7/8 AUG) - covered in Part 5a,
2. "First Encounters" (8 AUG - 21 AUG) - which is covered in this post,
3. "The Crisis" (21-24 AUG), and
4. "The Great Retreat" (24 AUG - 5 SEP)

And the geographic space into three areas:
1. "Northwest" - primarily central and eastern Belgium (and, later, northern France)
2. "Center" - southeastern Belgium, Luxembourg, and north-central France, and
3. "Southeast" - the Franco-German border between roughly Nancy and the Swiss frontier.

In the previous post we discussed:

The German invasion of Belgium that centered on the assault on the Belgian fortress city of Liege (in the Northwest area) as well as the small engagement west of that city where reconnaissance elements of the German 4te Kavalriedivision found out the hard way that mounted fighting for intelligence was a non-starter in 1914, and

The initial French assault around the town of Mulhouse in Alsace (in the Southeast), which gained back some ground lost in 1870 and, seemingly, validated the concept of GEN Joffre's Plan XVII.

In the center the opposing forces had not yet collided. The primary activity we discussed was the long ride of Sordet's Cavalry Corps, which pushed into Belgium as far as just south of Liege but found no major German units there, suggesting to Joffre that his attack plan for 3eme and 4eme Armee was workable in driving into the flank of the German drive into Belgium and dislocating the "hinge" of the big Schlieffen right wing.

Now we're going to try and quickly review the actions over the next two weeks - between the end of the first week and the beginning of the third week of August 1914 - because they involve a lot of moving and searching and not a whole lot of fighting across the general frontier.

Oh, there was fighting, but largely at the ends of the lines. The middle of August was largely a time of movement and maneuver as the two (and, later in the month, the British becoming the third) powers pushed through their operational plans.

Remember that the principal focus of this series of posts is on the contributions to the operations along the frontiers of the elements tasked with reconnaissance (and counter-reconnaissance), which in 1914 largely meant the traditional horse cavalry but now included aviation, both heavier- and lighter-than-air; aircraft and dirigibles.

Let's look first at the places where actual fighting was going on.

First Encounters - Northwest (8 AUG - 21/22 AUG)

It's not really correct to call the operations in this and the Southeast areas as "First Encounters"; both sectors had seen action in the first week of the war. 

In the Northwest the German Maasarmee - a reinforced armeekorps - had invested Liege, and the strategic reconnaissance elements of Höhere Kavallerie-Kommando (HKK) 2 pushed into east-central Belgium.

In the Southeast a reinforced French corps - VII Corps d'Armee (VII CA) - pushed into the German marches around the Alsatian town of Mulhouse. This attack succeeded in pushing the advance units of the German 7. Feldarmee back, but good recon by both ground and air elements discovered vulnerabilities in the French deployment that Generaloberst von Heeringen, commander of 7. Feldarmee, planned to use to give the impudent Frogs their conge'.

Let's start in the northwest.

The city of Liege itself was occupied on 8 AUG - the Belgian 3rd Army (along with assorted maneuver elements defending the city proper) had pulled out to safety in the west - but the ring forts around it held out. Between 8 and 12 AUG the true siege train including the superheavy 350mm/420mm artillery and two additional armeekorps, arrived and started hammering the Belgian fortresses.


Finally on 8 AUG the aviation unit attached to the German X. Armeekorps - Feldfliegerabteilung (FFA) 9 - began operations over Liege. These expanded on 11 AUG when the FFA's attached to the arriving armeekorps began operating. 

Two of these; FFA 1 (attached to the Gardekorps), and FFA 9, were tasked with strategic reconnaissance deep into central Belgium. According to Bowden (2017) these flights were generally successful; the German fliers located the bulk of the Belgian field army as well as determining that the French maneuver forces had not crossed the Belgian frontier in strength.

The remaining fixed-wing units were tasked with local reconnaissance over Liege, which Bowden (2017) says:

"...often saved the siege batteries from needlessly wasting their valuable armor-piercing ammunition on an already neutralized target."

So well done, flyboys.

Meanwhile, things weren't going so well for German recon troopers on the ground.

On 11 AUG elements of HKK 2 were pushing northwest towards the line of the Gette River towards the Belgian left and the main roads to Brussels. To hold down this flank the Belgian Cavalry Division posted the crossings of the Gette, including the most dangerous avenue of approach that led northwest from the town of Diest through the town of Halen (sometimes spelled Haelen), about 47km northwest of Liege.

The Belgian engineers failed to drop the bridge at Halen and four cavalry regiments of 4te Kavalriedivision from HKK 2, attached jäger infantry from 2te and 4te Kavalriedivisionen, and two battalions of horse artillery got across the Gette the following day.

Then, however, the German cavalry learned the hard lesson their counterparts had learned earlier at Waremme; that dismounted rifle and machinegun fire made mounted reconnaissance both unenlightening and lethal. 

Apparently the German cavalry - dragoons, cuirassiers, and uhlans - made as many as eight mounted attacks on the Belgian troops - cyclist infantry and dismounted Guide and lancer cavalry, with regular infantry arriving later in the day - and were shot to pieces.

The Belgians were roughly handled but the attackers lost some 500 troopers and over 800 horses (effectively ruining the four cavalry regiments involved), learned nothing they hadn't known before, and had to leave the Belgians in temporary possession of the ground.


It was turning out that mounted operations were pretty dangerous in the presence of 20th Century munitions. The setback ended what might have developed into a turning maneuver of the Belgian field army's left by HKK 2.

But in the big picture German operations in the Northwest weren't really going anywhere until Liege was reduced. That meant a German major-operational pause between 8 AUG and 16 AUG, when the siege was closed out and the German right wing forces released to push into central Belgium.

As Bowden (2017) notes, "...as of August 17th the German leadership was entirely unaware of where the allied forces opposite their right wing were located. Only the Belgian Army, standing opposite (German) First Army along the Gette River, was known..."

The map below gives you an idea of the progress of the German cavalry between 16 and 24 AUG. HKK 2 (operating in concert with 1. Feldarmee) is to the north of the green line, HKK 1 (with 2. Feldarmee) to the south. 

The Bowden (2017) assessment continues:

 "...in order for the German right wing's grand enveloping attack..to be successful, it was absolutely critical that the...allied left wing (was) located as quickly as possible. (W)hile the position of the French left could be safely assumed to be in the vicinity of Namur, the location of the BEF was a complete mystery."

The possibilities ranged from far to the west, to threaten 1. Feldarmee's "open" right flank, to tucked in next to the French 5eme Armee, or even hovering offshore to land behind the German advance. Bowden (2017) concludes:

"Only after the BEF was located could (1. Feldarmee commander) Kluck begin to concentrate his widely dispersed forces and take the offensive. Thus, with the success of the right wing's offensive at stake, it was imperative for the Fliegertruppe to locate the BEF as well as French Fifth Army as quickly as possible."

As you can see, this was a task for the fliers; it would take almost a week for the weary horse soldiers just to get to where the French and British might be.

 

 We'll discuss what happened when these forces met in the next part of this series. In between the fall of Liege and the end of the third week of August;

The Belgian Army eluded German encirclement to fort up in Antwerp. This was annoying for the OHL because it meant having to drop off a full armeekorps to mask the Belgians and prevent raids on German supply lines. 

German air recon units searched to the west, south, and southwest...but were largely confined to the immediate front of the 1. and 2. Feldarmee. This meant that while 2. Feldarmee aviation located advance elements of the French defenses around Dinant and Charleroi, 1. Feldarmee's fliers weren't far enough forward to find the British. 

French reconnaissance appears to have been either absent - the Armee de l'Air doesn't appear to have been very active over the German operational areas - or timid, in the case of the Sordet unit. As we mentioned earlier, the French cavalry reached the southern outskirts of Liege late on 8 AUG. The lead elements bumped into German lines, and rather than attempt to fight through them, pulled back to the southwest.

The worst part of that operation was the weather conditions - extremely hot and dry - and the distance covered, as much as 100km or more that day. Most of the cavalry mounts got little fodder and no water that day, and the long, hot march was hard on the relatively fragile troop horses.

Worse, Sordet's units got little rest after that; by 12 AUG the corps had retired southwest to Neufchateau. Still no Germans, so by 15 AUG Sordet's command had re-crossed the French border to fall in with 5eme Armee.


Interlude: Horses and Industrial War

One thing worth noting about the anabasis of Sordet's cavalrymen; the scope of war in 1914 was becoming too big, and the pace too demanding, for the most vulnerable piece of the recon elements, the animals that made cavalrymen what they were. Not just the French cavalry. All cavalry, and the horse-drawn armies it supported.

European cavalry (as opposed to the sort of horse-nomad riders of the Asian steppes) depended on big, "warm-blooded" horses bred to the work. These had to be strong enough to carry the heavily-equipped trooper, and sturdy enough to stand up to the hard riding of campaigning.

But horses are surprisingly fragile. Their legs and hooves didn't evolve to stand up to long plodding road marches, and the wear of even the best saddlery and tack caused galls and similar injuries. Cavalry mounts were also raised on grains - primarily oats - and couldn't and didn't stay healthy on browse alone. The war diary of HKK 2 noted that:

 "...nothing (from logistical support) happened to supply enough oats. Repeatedly it was asked for help...and finally, when we were told that there would be no oat supplies for three days, (we were directed to) slow down movement, if necessary..."

All the major combatants on the Western Front had similar problems with their mounts even before encountering enemy fire at places like Waremme and Halen. The problem with 1914 logistics was that once away from the railheads supplies had to be transported primarily by horse-drawn wagons; none of the armies had enough trucks (and France and Belgium largely lacked truck-passable roads) to move significant supplies.


That meant that the draft horses were under much the same constraints as the cavalry mounts; they needed water, fodder, and rest that the relentless pace and brutal marches demanded of 20th Century warfare just didn't allow. 

(The always-invaluable Bret Devereaux describes this as "the tyranny of the wagon" and does a terrific job explaining it here).

The opening month of the Great War showed how hard modern war was on the recon vehicle of the pre-industrial era. Horses were lamed, broken, and killed by more than bullets and shells; simply moving at the pace and over the distances required of operations in 1914 was debilitating, crippling, or lethal to the cavalry mounts if not their riders.

The track of the armies was signposted with the bodies of dead animals as well as people.


The BEF landed in the second week of August. This included the Cavalry Division as well as the four squadrons of the Royal Flying Corps. These air reconnaissance units assembled in Amiens on 11-13 AUG and from there transferred northeast to forward airfields around Maubeuge between 16-19 AUG. The first reconnaissance flights began after 19 AUG to find German troop units approaching the BEF position around the town of Mons.

Keep your eyes on this part of the front, because we'll be back here in the next post.

First Encounters - The Center (8 AUG - 21/22 AUG)

The real story of the central area was, in the words of Conan Doyle's detective, the dog in the nighttime.

French planning assumed that German mobilization would put maneuver units along the LD sometime around 13 AUG. That was the premise behind the Sordet reconnaissance; to find and surveil these troops.

Instead, the French cavalry found nothing because there wasn't anything there yet to find. As this little article notes:

"In order to find the German 3rd, 4th and 5th Armies, the French cavalry would have had to advance across the Belgian Ardennes to the border with Germany and Luxembourg; it was unable to do so. The German deployment was not completed until 17 August and the German 5th and 4th Armies did not begin their advance until 18 August. The French had great difficulty understanding why the Germans were not as far to the west as they expected them to be."

The other difficulty with the Central area was the terrain; little developed, heavily wooded, badly broken with hill-and-valley topography, the Ardennes was a reconnaissance nightmare. The tree cover meant that troop movement or bivouac areas were nearly invisible to aerial observation, while the topography meant that sightlines were lethally short; a cavalry patrol could easily find itself practically on top of an enemy unit before hearing or seeing it. 

But if the cavalry didn't bump into that enemy, it was unlikely to hear or see it at all.

Terence Zuber's 2007 Ardennes 1914 does a good job of describing the issues that piled up at Joffre's GQG to precipitate the eventual disaster in the forests, a combination of tactical misallocation or mistakes and strategic fixation.

The strategic part was influenced by where the fighting was; it looked obvious that German forces were active - meaning, probably, concentrated - at the "ends" of the frontier lines; in Belgium around Liege, and in Lorraine near Mulhousen.

Zuber (2007) says that the French intelligence estimate on 16 AUG placed a total of seven German AKs - armeekorps - along the Meuse in two feldarmees, three AKs (one army) in the Belgian Ardennes, three more AKs (one army) in Luxembourg, and seven AKs (two armies) in the southeast around Alsace and Lorraine. Five AKs were assumed to be in the East, and one AK (Guard Reserve) couldn't be found.

This conformed to the apparent actions along the frontiers; weighted up in northwest and southeast, thin in the center. So for the French higher, GEN Joffre at GQG, the German Army dog was doing nothing in the Central area night (and day) time.

In fact, the estimate was off by a full three armeekorps in a whole army - 5. Armee - in the center near Metz along with the six AKs known to be there in 3. and 4. Armee

And, worse, that the mass of troops known to be in the central area was thought to be intended to reinforce the German right wing attack through Belgium:

"The French assumed that VIII AK and XVIII AK (that is, two of the three AKs in 4.Armee) were covering the movement of the German mass of maneuver from the area of Luxembourg and the rear of Metz to the northwest. (Zuber, 2007, p.95)"

The French central area maneuver units did themselves no favors tactically, either:

"General Arbonneau, with the 4th and 9th divisions of cavalry, was sent forward on 17 August to the area of Virton and Neufchateau and in 18 August pushed back the German 3. KD (kavalriedivision). No attempt at deep reconnaissance was made by either 4 DC or 9 DC, which stationed themselves a safe 10km in front of the French infantry corps." (Zuber, 2007, loc. cit.)

Again, the problem wasn't that there were no German maneuver units in the central front area; the problem was that the German units weren't where the French reconnaissance elements thought they should be;

"French cavalry and aerial reconnaissance could find no German units in the area of Longuyon-Virton-Tintingny-Arlon...which was essentially correct." (Zuber, 2007, loc. cit.)

You can kind of understand this. GQG was being carpet-bombed by paperwork; status reports, requests for orders (or amplification/explanation of earlier orders), intelligence reports. And the immediate attention of the higher was drawn to where the fighting was already; eastern central Belgium - the "Northwest" - and the Southeast in Lorraine and Alsace.

So if the Central area was quiet? Fine! Let's assume that the damned Boche are holding there to load up the northwestern attacks and southeastern defenses. We've got enough to do there without haring our recon troops after a corporal's guard holding down the lines in Luxembourg.

That was the French situation. What about the Germans?

Showalter (2020) notes that while the cavalry was struggling with dead, dying, and stricken horses the aviators were working hard; FFA 9 and other aviation units were doing good service tracking the Belgian main army west of Liege.

But the same short-range focus was affecting the Imperial commanders.

"While effective at the close reconnaissance, the airmen did nothing to extend out long-range and find the BEF or the left wing of the French Army. Due to the structural lack of an aviation staff officer, aviation reports, messages, and intelligence...frequently did not find their way to the army intelligence staff officer. It is claimed that (the German) First Army was never made aware of about fifty percent of the air reports."

This was true for the other armeekorps and feldarmee as well. So it's here that we should discuss headquarters staff organization and how that affected the reconnaissance operations of August 1914.


The Life of The Staff: One Long Loaf.

Let's take a random German armeekorps as an example.

The corps commander - an O-9/three-star generalleutnant, usually - had what a U.S. Army corps would call the "headquarters and headquarters company (HHC)" of about 300 all ranks. This included everyone, from the privates assigned as runners and guard-post rotations to the chief of the corps staff, probably a senior colonel/O-6.

Below the stabschef were three (or four) "operational" staff sections, presumably run by O-5 oberstleutnants;
Section Ia ("operations and tactics" - the equivalent of a U.S. ops section, or G-3); this was run by an officer designated the 1.GSO, who was considered the "senior staff" officer,
Section Ib ("affairs behind the lines" - seems to be sort of a combined G-1/G-4/G-5 position, personnel/supply and civil affairs)
Section Ic ("intelligence" - the G-2 equivalent)
Section Id ("assistant to Ic" - the source I have for this doesn't explain the duplication here. My guess is that this was a blank file activated in wartime if needed.

The problem here is two-fold.

In principle what a modern U.S. operation would call the "air-tasking order" would be generated by the Stabs Ia, operations staff from the corps commander's intent. 

Then the intelligence gathered by those aerial operations would be forwarded from the forward airfield to the Armeekorps Ic, intelligence, for use in preparation of the next operations order.

But both phases were complicated by the inadequate staff training and preconditions of 1914.

As reported in Bowdon, 2007:

"On many occasions the various HQ staffs failed to dispatch instructions to their flying sections. As a result, the airmen remained grounded during decisive moments in the fighting. In other cases...flying sections dispatched critically important intelligence that never reached...the army commander." (p. 123)

So overworked staffs - unfamiliar with the aviation branch and it's needs, capabilities, and limitations, failed to use it effectively - an operational failure - or collect the information it provided when it was well-used, an intelligence failure.

The same limitations would have affected the FFAs flying for the feldarmees.

This was largely remedied by the creation of an "aviation staff officer" (Stabsoffizier der Flieger, Stofl) at the feldarmee level in the spring of 1915, as well as presumably similar staff positions at the armeekorps.

But that didn't help our German - and, very likely, French and British - staff officers in August, 1914.

First Encounters - The Southwest (8 AUG - 21/22 AUG)

When we last looked at the activities in and around the Alsace/Lorraine vicinity these included:
1) a French offensive which pushed a portion of the 1er Armee - VII Corps (14re, and 41er Divisions de Infantrie (DI) and one brigade from 57eme Reserve DI) and 8eme Division de Cavalerie (DC) - across the border into the valley of the river Ill around Mulhouse, driving back the defenders from the 7.Feldarmee, and
2) German aerial and cavalry recon efforts that identified soft sectors in the French final advance lines that offered opportunities for counterattack.

This succeeded; the initial French incursion was successfully shoved bloodily back on 9-10 AUG.

That's where the two sides paused until French deployment was completed on 13 AUG when, in accordance with Plan XVII and GEN Joffre's intent, the French 1er and 2eme Armees pushed across the German frontier.

Opposing this move were the 6. and 7. Feldarmee; notionally separate commands the two had been combined under the commander of 6.Feldarmee to ensure prompt coordination before the anticipated French offensive.

That commander was perhaps the most Imperial of all Imperial commanders, GEN Rupprecht Maria Luitpold Ferdinand, Crown Prince of Bavaria, Duke of Bavaria, Franconia and in Swabia, Count Palatine by the Rhine.


This boyo wasn't just an idle royal body, though. He's still considered one of the best of the Imperial general officers. He'd been instructed to fight a delaying action on the German left to suck the French maneuver forces into the kill sack for the "strong right wing" to encircle, and did.

From 14 AUG to 16 AUG the two German armies did just that. 

By 16 AUG, however, German reconnaissance (mostly aerial, augmented by cavalry patrols and ground contact reporting) had determined that the French strength attacking into Lorraine was much smaller that anticipated; seven corps d'armee rather than fifteen. Bowdon (2017) says that:

"It was at this moment that the mentally weak Moltke started to lose control over his subordinates and the overall situation. Instead of firmly ordering Rupprecht to continue the withdrawal and take up a defensive position...he dispatched a cryptic message that allowed Sixth Army HQ to...launch a counter-offensive whenever the opportunity presented itself." (p.76-77)

Bowdon (2017) notes that poor weather and the press of retrograde displacements had limited air activity between 15 and 17 AUG, but that on 18 AUG a patrol from FFA 20 (the XIV.Armeekorps flying detachment) found an untenanted gap in the French FLOT. The 1er Armee was still attacking to the east towards Strassburg, while 2eme Armee had turned north to envelop Metz.

After a day to prepare the counterattack, now known as the "Battle of Morhange-Sarrebourg", kicked off on 20 AUG.


(This site, crafted by "Pierre Grande Guerre" in 2019, provides a terrific little tour of the Lorraine engagement sites and history of the actions here, if you want to take a look. I've stolen the little snapshot of the Oron Memorial above from him. Go; it's worth it.)

Bowdon (2017) notes that "(h)aving had plans to renew their advance...the French troops neglected to establish defensive positions during the evening of the 19th." so that when the 6.Feldarmee artillery prep began at 0400 20 AUG the surprised fantassins were hammered even before the German and Bavarian infantry tore into them.

By 21 AUG the French right was in headlong retreat. This would continue until the front stabilized inside French territory.


Summary: First Encounters - Reconnaissance Operations

Northwest: German air operations were locally quite successful, both spotting and directing artillery fire. The German cavalry was discovering how lethal modern weapons were for ginormous targets who couldn't low-crawl. French air operations were still nonexistent and Sordet's cavalry wandered around aimlessly. Belgian cavalry and aircraft appear to have, like the Germans, had local value but (unsurprisingly given their small numbers) little insight into the bigger grand tactical and strategic picture.

Center: The important things were the things that weren't happening; the French recon elements - air and particularly Sordet's Cavalry Corps - not looking hard enough for, and not finding, the German 3., 4. and 5. Feldarmee in the Ardennes sector, giving Joffre and GQG the confirmation they sought that German strength was meager and German operations largely confined to linking the left and right.

Southeast: Air recon, much the same as we saw in the preparation phase: German fliers kicking ass, the French aviators nonexistent. 

The German cavalry seems to have been doing what it could within the sort of tactical limitations we've discussed.

But here the French cavalry really began to show it's problems. There's no way the counter-offensive of 20 AUG should have been undetected until the moment the German howitzer rounds began to impact. Some sort of aggressive patrolling should have revealed the buildup of German and Bavarian infantry. You can ding the German horsemen for stuff like Waremme and Halen, but at least they were trying to follow their doctrine. We'll discuss this in detail in the next chapter, but the French cavalry seems to have been defeated before they mounted up.
