The German Army in The Ardennes 1914

Strategy and Tactics

The defeat of the French 4th Army by the German 4th Army in the Battle of the Frontiers spelled the failure of the French war plan. Combined with the Russian defeat at Tannenberg, the Entente strategy for simultaneous Russian and French attacks against Germany had also failed. French losses were far higher than German, and the resulting disparity in combat power meant that the French were not even able to hold the last significant terrain obstacle, the Meuse.

These victories were not accomplished by superior war planning or by operational excellence. The French had anticipated the German advance to the north of the Meuse and had devised an excellent means defeating it. The German advance through Belgium was hardly the thing of wonder that it has been made it out to be. That the French plan did not succeed, while the German plan did, had nothing to do with strategy, but was solely the product of German superiority at the tactical level.

There is a school of thought which maintains that the German ‘genius for war’ was the product of the excellence of the German Great General Staff, that is, German victories were due to superiority at the operational and particularly at the strategic levels. There is no evidence to be found for this proposition either in the Battle of the Frontiers as a whole or in the Ardennes on 22 August. The Chief of the General Staff, the younger Moltke, did nothing to give German planning operational coherence: the seven German armies acted virtually independently of each other. The German 5th Army attack plan for 22 August, written by a General Staff major general, left a corps-sized gap in the army centre that was not filled until late afternoon, and which nearly resulted in a French breakthrough, while the army right flank was hanging completely in the air. The 5th Army plan was not coordinated with the 4th Army. The 4th Army moved to the south on its own initiative at the last minute to cover the 5th Army right flank, in turn leaving the 4th Army’s own centre outnumbered and dangerously thin. Due to the 5th Army’s poorly thought-out attack, of the ten German corps in these two armies, two corps could only be brought into action late in the day and one not at all, while all the French corps were engaged. The only German senior officer to display sound operational ability in the Ardennes was the commander of the 4th Army, the Duke of Württemberg, a capable professional soldier but also the hereditary ruler of a German state and hardly the prototypical General Staff officer. But the real victors on 22 August in the Ardennes were the officers and soldiers of the divisions of the German 4th Army, which dealt the French 4th Army – the French main attack – the most stinging defeats in the entire Battle of the Frontiers.

The German Army

The German army’s 1906 infantry regulation presented an effective tactical doctrine based on the need to gain fire superiority as well as on offensive action based on fire and movement. German training in this doctrine was realistic and thorough, and concluded every year by several weeks of live-fire gunnery exercises and tactical problems conducted at MTA. French doctrine did not include the concept of fire superiority and the French did not have adequate training areas. German doctrine and training also emphasised the meeting engagement and individual initiative at the tactical level; the French, on the other hand, emphasised linear engagements tightly controlled at the division, corps and army levels.

The German army won the Battle of the Frontiers because of superior peacetime doctrine and training. German patrolling and reconnaissance were vastly superior to the French. In almost every instance, German reconnaissance provided excellent reports on French movements while blinding French cavalry reconnaissance. French air reconnaissance was largely ineffective in the forested Ardennes; the French senior headquarters formed an entirely erroneous impression of German movements and intentions. On 22 August none of the French divisions had any idea that major German forces were in their immediate vicinity.

On 22 August the two French armies were advancing to the northeast, while the two German armies were attacking to the west. All of the subsequent battles were meeting engagements. German units moved quickly and deployed smoothly. French movements suffered from friction and their deployment was slow and uncertain. Once engaged the Germans smothered the French with rifle, MG and artillery fire and gained fire superiority. If the Germans were on the defence, this fire stopped the French attack. If attacking, the Germans then closed with and destroyed the French infantry by fire and movement. Widespread myths notwithstanding, there were no trenches, and the only barbed wire encountered was that which the Belgian farmers used to fence in their livestock.

German Infantry

Prior to the war there had been considerable concern that the nerves of the troops would not stand up to the terrors of modern combat. As Otto von Moser noted, these battles proved beyond a doubt that the German troops were equal to the task. To Moser’s observations it must be added that the French troops were often not equal to the requirements of the modern battlefield; after a few hours of combat, most French units cracked. This was due to inadequacies in French training.

This was not to say that everything went flawlessly. In particular, the infantry often attacked without waiting for the fire support of MG and artillery to soften the enemy up. Losses were even higher than the most sobering peacetime projections: in Moser’s units more than a third of the officers and nearly a third of the enlisted men became casualties on 22 August. But French casualties were even higher. As The commander of the 25 ID, speaking of IR 116 and IR 117 at Anloy, said:

‘In spite of these (terrain) difficulties, in spite of the casualties and the intense enemy fire our troops worked their way forwards. As was characteristic of our men at this time, they got the bit in their teeth and pushed forward, which cost us a great many casualties … Nevertheless! Who would dare to criticise the wonderful aggressive spirit of our soldiers?’

In the battle the general was describing, the terrain was very close and the action was taking place at 400m range or less. Artillery support was practically impossible. Using fire and movement, the German troops pushed back the French, one terrain feature at a time. There were no ‘bayonet charges’. The German infantry simply kept on battering the French, undeterred by casualties.

The performance of the German infantry on 22 August 1914 was exceptional, the result of high morale, intelligent doctrine, effective training and excellent leadership.

German Artillery

The commander of the VI RK listed the common complaints about the performance of the German artillery. The infantry pushed quickly forward and the artillery was too slow to keep up. The German artillery was especially slow in occupying covered positions. The result was that the German artillery often fired into its own infantry. The French gun had a maximum effective range 2,000m greater than the German gun. The French artillery was better trained and more tactically proficient; the French operated flexibly, by batteries, the Germans employed clumsy three-battery sections.

Most of these criticisms seem to have been coloured by experiences later in the Marne campaign. During the French withdrawal, their artillery was very effective as a rear-guard. During the battle of the Marne the French emptied their magazines, firing prodigious quantities of shells that smothered the German infantry.

But during the meeting engagements on 22 August in the Ardennes the German artillery was almost always superior to the French. If it was sometimes slow to get into action, the French artillery was slower. The Germans were usually able to fight combined-arms battles; the French infantry was often destroyed before the French artillery got into action. The Germans frequently brought individual guns right into the skirmisher line, where they provided highly effective fire support at point-blank range; the French never did so. The German light and heavy howitzers proved their worth.

Both the German and the French artillery soon discovered that frequently the terrain did not provide observation of enemy positions. Rather than do nothing, both artilleries employed unobserved area fire (Streufeuer) against suspected enemy locations. This was not provided for in either the French or German pre-war artillery doctrines, because it was felt to be ineffective and wasteful of ammunition. However, both sides used it from the first day of combat on, and to good effect.

German Cavalry

German doctrine emphasised that cavalry needed to be aggressive during the battle in developing opportunities to both participate in the battle as well as to operate against the enemy flank and rear. Doctrine also stated that cavalry was the arm best suited to conduct pursuit.

While the 3 KD and 6 KD had been very effective in the reconnaissance and counter-reconnaissance roles before the battle, during the battle they accomplished nothing. The 3 KD commander decided that the terrain prevented the division from accomplishing anything and resigned himself to inactivity. 6 KD was used to guard the army left flank. Neither division conducted a pursuit, either on 22 or 23 August, although the Colonial Corps would seem to have offered a fine target for 3 KD and the right flank of the French VI CA an even better target for 6 KD.

It appears that the cavalry learned during the approach march that a mounted man presented a fine target and that even small groups of infantry were capable of blocking cavalry movement. By 22 August the senior cavalry commanders were thoroughly intimidated: they avoided serious contact and were unwilling to attempt to move large bodies of cavalry anywhere that they might be subject to small arms or artillery fire. Coupled with the unimaginative operations of the 5th Army headquarters, the timidity of the cavalry leaders cost the cavalry the opportunity to have made a major impact in the battle.

Command and Control

The German army discovered that modern means of communications were unreliable, an observation that would be repeated by practically every subsequent army. This included the telephones that connected army headquarters to OHL, which utilised the seemingly infallible civilian telephone net. As Crown Prince Wilhelm complained, the telephones became so overloaded with traffic that the command and control system at times broke down completely. Nevertheless, German reporting was good and with the exception of the breakdown between V AK and XIII AK German senior HQs kept each other informed.

Liebmann’s Evaluation of German Doctrine and Training

In his study of how German doctrine and training withstood the test of combat in 1914, Liebmann concluded that ‘In 1914, none of our enemies possessed a doctrine which was superior in combat to that of the German army, even though we must acknowledge that German doctrine had weaknesses’.

‘Foremost among these errors was a failure to recognise the effect of firepower, even though German doctrine was based on firepower … It must also be recognised that even the most conscientious preparation in peacetime does not insulate against similar errors.’

‘The German infantry proved itself to be superior to that of the enemy. Its high morale and discipline and its powerful offensive spirit, the product of its traditions and decades of training, allowed it in many cases to simply overrun the enemy infantry’. But Liebmann said that this superiority applied only to mobile warfare, and contended that attacks later in the war against a prepared enemy defence failed disastrously.

Liebmann said that conducting the firefight with thick skirmisher lines was effective and that the casualties incurred were acceptable as were forward bounds by individuals or by squads. Casualties only became serious when long lines bounded forward or entire fronts conducted assaults. And although the German army emphasised fire superiority, gaining and using it in actual practice proved difficult. A much more serious deficiency in German doctrine and training was the failure to recognise the difficulties in infantry–artillery cooperation. In German exercises the problem was glossed over. On the other hand, the German cavalry performed its reconnaissance function everywhere with distinction.
