Die Katastrophe Von 1806
Part II

Jena/Auerstadt
The Destruction of Frederick's Legacy

By Major J.E. Lawson, USA

Part I:

Discussed in the last article were the inherent weaknesses of the Prussian Army of 1806. Many of these can be attributed to the stubborn refusal of the military hierarchy in Prussia to bend with the winds of reform; other weaknesses were the result of over two decades of partial neglect of the military by the Prussian civilian bureaucracy. British General Henry Lloyd succinctly describes, and then prophetically characterizes what was to happen to Frederick's great army when he wrote in 1781, "The Prussian army, being composed chiefly of strangers of different countries, manners, and religion, are united only by the strong chain of military discipline; this and a most rigid attention to keep up all the forms and discipline established, constitutes a vast and regular machine, which being animated by the vigorous and powerful genius of their leader, may be justly accounted one of the most respectable armies in Europe; but should this spring, however, languish but for an instant only, the machine itself, being composed of such heterogeneous matter, would probably fall to pieces, and leave nothing but the traces of its ancient glory behind." [1]

Such was to be the fate of the Prussians on 14 October 1806. Neither Frederick WiIIiam III, nor any of the old campaigners who composed the Ober Kriegs Collegium (a council of old soldiers supervising the Prussian Army) would prove capable of utilizing, much less animating, the Prussian soldier as Frederick had done.

The Prussian King had preferred to rely on neutrality against the threat of French domination in Europe, but when he was informed of Napoleon's intention to offer England the Prussian's holdings in Hanover behind his back, this final insult to the already muchtrampled Hohenzollern honor was too much for even the dilatory Frederick William III.

Thus on 9 August 1806, the cabinet ordered the army from its garrisons. Prussia had finally emerged from her neutrality; notably she could not have picked a much less advantageous time to do so. Prussia could not depend on England for support; it was highly unlikely that Austria would face Napoleon again, and although the Tsar had promised support, Russian forces were far removed from the area of operations. Prussia would face Napoleon's victorious Frenchmen essentially alone.

On 25 September, Frederick was to send an ultimatum to Napoleon: all French troops must withdraw behind the Rhine leaving Prussia free to organize a North German Confederation. it was hardly an ultimatum that the French Emperor would accept, yet, for some unexplained reason, Frederick still believed there was a good chance for compromise with the French. Worse still, the Prussian King allowed his senior officers to believe that the chance for accomodation with Napoleon was likely. Thus, at a time when super-human efforts were required of Prussia, both the army and the nation responded feebly at best.

Preparations for war were poorly coordinated in the Prussian camp. The mobilization had been inefficient, for out of a possible strength of over 200,000 troops, nearly half were to remain in their garrisons, depots, and fortresses. Worse still, over 30,000 troops were left in East Prussia as if there were a threat from their Russian allies. Frederick William III also put little pressure on the smaller German states for support; other than a small Saxon contingent, there was to be no other support for the Prussians from this quarter. Thus the possibility for a further 30,000+ men to fight on the Prussian side was unrealized.

If the political leadership of the state was inept, the Prussian army was even worse off. This was because it was burdened with three almost independent commanders. Three separate armies were deployed into Saxony. Frederick had entrusted overall command to the over-aged Duke of Brunswick, who also commanded the largest of the three separate elements. However, Prince Hohenlohe, who had had considerable command experience in 1794 and now commanded his own army, decided not to subordinate himself to the Duke, and proceeded on his own semi-independent course of action. General Ruchel, commanding a corpssized army, was essentially caught in the middle between the devisiveness of his two royal counterparts.

Hence, the Prussian field force was divided into two uncoordinated main armies, a weaker third element, and a distant reserve at Magdeburg commanded by Wurttemberg. As Napoleon began his advance through the Thuringian Forest in the direction of Dresden on 6 October, the Prussian forces were deployed as depicted on Map 1.

Each of the Prussian armies was sub-divided into divisions, which as stated in our first article, had undergone reorganization into the combined arms pattern of the French corps. However, none of the Prussian commanders had any experience in handling this new kind of organization, and all persisted in the Frederickian convention of issuing detailed orders to every regiment.

In addition to this outdated method of tactical organization, there was no question that the higher generalship of the Prussian Army had fallen below the acceptable standard of the past. Brunswick refused to make a major decision without referring the problem to councils of war, in which the King's many advisors played an argumentative and disruptive role. Hohenlohe offered non-compliance, if not outright disobedience to Brunswick's orders. Furthermore, Frederick William determined to stay at Brunswick's headquarters, thus superimposing his sizeable military and diplomatic suite on an already overburdened operational agency. The result was confusion and indecision. [2]

Each of the Prussian commanders also had his own idea on how the campaign should be conducted. Brunswick urged a general advance on what was considered to be the French line of communications centered on Wurzburg; while Hohenlohe argued for an offensive on the east side of the River Saale. Both commanders had positioned their forces to support their particular scheme of maneuver, resulting in a dangerous dispersion of the two main Prussian elements.

By the time the days-consuming Prussian Councils of War had decided on a plan, the initiative had been snatched away by Napoleon's clebouchment in the vicinity of Saalburg. Scharnhorst wrote of his disgust with the constant haggling at Prussian Headquarters, "What ought to be done, I know quite well, what will be done, only the gods know." [3]

Napoleon, too, had had problems in initiating his campaign as rapidly as desired. Having reached Wurzburg on 2 October, he found his army beset with logistic problems and confusion. Through super-human effort, and thanks to Prussian indecision, he was able to quickly put things right and begin his advance. Passing through the Thuringian defiles with three Corps abreast in their classic V-formation behind a cavalry screen of light horse, Napoleon found the eastern exits from the forest guarded by dispersed detachments of General Tauenzien's division. Tauenzien, finding himself beset by a flood of Frenchmen, withdrew, leaving the door open for Napoleon's consolidation on the east side of the forest.

The Prussian dispositions (see Map 2) were dangerously dispersed. The threat was obvious; nonetheless, another wrangling Council of War was called to decide what would be the response to it. A concentration around the town of Blankenhain was eventually ordered, but in perfect 18th century form, Brunswick also decided to send a force of some 11,000 troops under the Duke of Saxe-Weimar to maneuver behind the French to harass their lines of communications.

Along with this force went a disproportionate amount of light infantry. As was discussed in the previous article, the Prussians were sadly lacking in light forces, and the 6 battalions which accompanied Saxe-Weimar were to be sorely missed on the plains of Jena.

Meanwhile Hohenlohe continued to advance, contrary to the orders received from his superior. A short, but decisive engagement on 10 October was to shatter his offensive spirit. Prince Louis Ferdinand, the hotblooded nephew of Frederick William, commanded the advanced units of Hohenlohe's army. Although ordered to defend behind the Saale River, the impetuous Prince advanced across the river to confront the advanced guard of Lannes' Corps.

Advancing with his 8300 Prussians and Saxons in perfect Frederickian order-two ranks deep and the left flank refused forward, Louis' force was fixed by energetic skirmishing by the French advanced guard while Marshall Lannes maneuvered with his lead division to flank the Prussian left. The battle lasted a mere four hours, and only 5500 Frenchmen were ever engaged, yet the Prussians lost roughly one third of their strength, 27 guns and the life of their commander. French losses were approximately 200. [4]The foundation of the Prussian military machine was beginning to crumble.

The importance of this sharp skirmish at Saalfeld lay less in the tactical or strategic sense than in the psychological effect it had on the defeated soldiers and on the Prussian high command. After confused marches and counter-marches which seemed to have no other purpose than exhausting the soldier's energy, the poorly supplied Saxon troops began to wonder whether they had joined the wrong cause. Stories spread that the Prussian generals planned to sacrifice the Saxons to cover their own retreat.

While Brunswick concentrated the main army near Weimar, Prussians and Saxons at Jena fought over supplies, firewood, and bivouac areas. Suspicion quickly turned to outright lack of confidence. During a march through Jena on 12 October, one column panicked at the totally groundless report that French troops were between Jena and Weimar. By night fall, Hohenlohe managed to settle his troops in unreconnoitered assembly areas, and prepared to defend against Lannes' driving advance from the south. No one knew for sure where the French Army was; rumor ruled the Prussian camp. In the confusion, both Hohenlohe and Brunswick failed to act on the one most important piece of news the Prussians received that day: French cavalry was in Naumburg, fifteen miles north of Jena. [5] Prussian forces consolidate around J Weimar (12 October).

The Prussian High command had been shocked by the defeat and the death of Louis Ferdinand. Both Ruchel and Saxe-Weimar were ordered to join Brunswick as quickly as possible. Hohenlohe withdrew his scattered forces to Jena, where, with his Saxons almost mutinous and his Prussians in disorder, he finally managed to rally his forces. Ruche[ and Brunswick achieved a confused concentration around Weimar, but SaxeWeimar was still a great distance away (see Map 3).

Throughout these two days of hard marching, the sluggish Prussians had managed to average just over half the distance covered by the French. As previously mentioned, major French elements under Davout and Murat were already converging on Naumberg, far north of the Prussian positions. Staff work had been poor, and the Prussian Headquarters was absolutely ignorant of the location of most of the Grande Armee.

Fortunately for the hapless Prussians, the French troops were to receive a rest on the 13th, with the exception of the corps now consolidating. Napoleon issued orders to speed up the movements of Soult's Corps and the Guard infantry, which were now converging on Jena. At the same time, he sent orders to Davout and Bernadotte covering two contingencies. If they heard firing at Jena, they were to march via Naumburg on the west bank of the Saale to envelop the enemy's flank. If no enemy attack developed, they would receive further orders on the morn.[6] He then was to conduct a personal recon of the Prussian forces in the vicinityof Jena.

He was to see a great deal, thanks to the Prussian surrender of the heights on the west bank of the Saale. Hohenlohe's covering force had given up this difficult terrain feature and withdrawn in search of more level ground for fighting. This was again indicative of the Fredrickian mentality which was so pervasive in the minds of the senior Prussian commanders, Lannes' arriving at daybreak with his advance guard, promptly took possession of the Landgrafenberg, a high plateau overlooking Jena to the south and dominated by a round hill, the Dornberg, to the north.

At 1600 on the 13th, the Emperor arrived, dismounted, and walked forward over this ground with Lannes until they came under fire from the enemy outposts. Napoleon had a clear view to the west where nearly 30,000 Prussian troops were visible. He estimated that Hohenlohe's troops comprised the whole Prussian army. Without checking this presumption, he immediately ordered all of Lannes' corps and the Guard Infantry to occupy the Landgrafenberg that night.

And what were the Prussians doing during this nearly two-day respite they had been granted since their arrival at Jena. Naturally, another Prussian Council of War was called to decide upon a course of action. With Davout's threatening position at Naumberg having finally become too obvious to overlook, it was decided late on 13 October to withdraw. Orders went out for the retreat of the main Prussian army to Merseburg along the road on the west bank of the Saale, while Hohenlohe's smaller force covered the withdrawal from positions near Jena. In contrast to the vigorous French advance, the Prussians failed to send out security forces to clear the intended escape route and were accordingly ill-informed of Davout's dispositions.

This was partly due to the lack of light troops available for this mission. Thus, on the evening of 13 October, Napoleon was maneuvering to bring the bulk of the Grande Armee to bear on the Prussian rear guard at Jena while Brunswick and 63,000 men struggled along a single road toward Auerstadt and Davout's thoroughly aroused III Corps. The stage was now set for one of the most decisive battles in the annals of military history. [7]

At 0630hrs on the morning of the 14th, Napoleon gave the signal to advance. The dense fog caused Lannes' attack to swerve too far to the left, thus blocking Augereau's deployment. When Augereau was finally able to bring his forces to bear, he found the terrain on the left extremely compartmentalized by deep ravines and wooded areas.

Had the Prussians had sufficient light forces in this area, the going could have been made extremely unpleasant for Augereau's VII Corps. Meanwhile, on the right Soult had managed to advance as far as Rodigen, where he halted for his artillery to catch up. As Ney's VI Corps marched onto the battlefield, a hole had developed in the French line on Augereau's left. Without waiting for orders, the impetuous Marshal plunged into the melee in time to ward off a counterattack by the Prussians and to retake what little ground had been lost.

On the Prussian side, activity ranged from organized panic among the Saxons to pure sloth on the part of Hohenlohe. Prussian artillery fired aimlessly, exploding a Saxon ammunition wagon near Lutzeroda, and occasionally felling a clump of French soldiers. Hohenlohe's forward defenses were alert and ready for the attack, repulsing several of Lannes' assaults in hand-to- hand fighting around the Closwitz Woods.

The Prussian division commander, Tauenzien, sent back several calls for help, but Hohenlohe only responded after an intrepid attack by Lannes and Ney had already won the western slopes of the Dornberg and the burning town of Vierzehnheiligen. Prussian infantry, attacking in rigid waves, was badly mauled by a battery of twenty-five guns personally assembled by Napoleon on the Landgrafenberg. Throughout the morning, Brunswick's slow march had snailed through Auerstadt; 13,000 men under Ruchel were trudging through Weimar; Saxe Weimar's 11,000 men were thirty miles away; and the Duke of Wurttemberg with 15,000 men in Halle in reserve would have been no farther removed from the battle if he had stayed in Berlin. [8]

Towards 1100hrs, Hohenlohe finally mounted a coordinated counterattack in the vicinity of Vierzehnheiligen. With band playing and flags flying, Hohenlohe was to make his major effort, advancing in Potsdam parade ground order, in echelon from the left with his artillery moving between his battalions. This concerted effort might well have succeeded, for French troops were now somewhat in disarray.

However, Hohenlohe's men were untrained for street fighting, and upon reaching the outskirts of Vierzehnheiligen were ordered to halt. Confronted with a dilemma for which their doctrine and training had ill prepared them, the Prussian commanders ordered their men to do what they best knew how-battalion volley on command in the open. For two hours, 20,000 infantrymen remained exposed to French marksmen who were nearly untouched behind the cover of garden walls and village masonry. Hohenlohe could think of nothing better to do than to wait for reinforcement from Hotzenclorf and Ruchel. [9]

Between 1200 and 1230, Napoleon judged the time to be right for a final push. With the cavalry divisions of Klein, Nansonty and d'Hautpoul nearing the field, he ordered a general advance. For the first hour, though going back steadily and despite heavy casualties, the Prussians maintained some semblance of a front. "Extreme measures" were required to keep some of the regiments from breaking. To the credit of the Prussian officer corps, commanders at almost all levels exposed themselves without regard to safety to try and inspire their men.

It was, however, too little and much too late. By 1430, Hohenlohe's army had been reduced to fugitives, only one or two units holding together in squares. The Prussian Colonel von Hopfner described the scene, "Those [Prussian] troops withdrawing on Weimar were in full flight; only one unit remained steady-it was the Saxon Grenadier Battalion Winkel with whom the Prince [Hohenlohe] was and who commanded it personally for a time. In this terrible moment, when defeat and confusion was everywhere, only this battalion stood like a rock." [10]

As a final encore to this disaster, one must not forget the valiant but vain attack by General Ruchel. "Ruchel came tramping onto the lost battlefield, plowing his way through the rout with difficulty," wrote John Elting. [11]

Ruchel's attack did manage to initially stagger the French as he managed to gain the plateau in the vicinity of Kapellendorf. Once again, however, the Prussians halted to deliver their touted volley-fire, and soon they were exposed to the withering fire of almost the entire French army. By mid-afternoon, Ruchel's troops were in full retreat and the Battle of Jena had become a total rout. Clausewitz probably best critiqued the Prussian performance at Jena when he wrote, it was "when the Prussian generals . . . all threw themselves into the open jaws of destruction in the oblique order of Frederick the Great, and managed to ruin Hohenlohe's army in a way that no other army has ever been ruined on the actual field of battle-all this was due not merely to a manner which had outlived its day, but to the most downright stupidity to which methodism has ever led." [12]

Jena had seen approximately 50,000 Prussians and Saxons matched against some 96,000 French (40,000 of whom were not ever engaged). The French losses were estimated at somewhat over 5,000; the Prussians lost over 11,000 killed, 15,000 taken prisoner, 200 cannon and over 30 flags. But even worse was the fact that what remained to Hohenlohe had been reduced to nothing less than a horde of fugitives, where no rally could be accomplished nor any semblance of a rear guard action was possible.

Auerstadt

To the north around the small village of Auerstadt, the results were even more remarkable. In accordance with his orders, Davout had discovered that, after crossing the Saale River, there was no way to march on the enemy other than by the long, steep slope which led to the Hassenhausen Plateau. This road, which crossed the Pass of Kosen, ran directly into the road to Freiburg, which was the escape route as prescribed by Brunswick for the Prussian army. [13]

After colliding with the Prussian advanced guard, the imperturbable Davout seized the heights and then began to race his troops forward across the Kosen bridge to support his position.

The Prussians, however, were not as quick to seize the initiative. General Schmettau, commander of the lead division, halted his troops to form up and then stood in the open volleying at Hassenhausen. Had he advanced to try and push the French from their tenuous positions, he might very well have saved the day. As it was, all he accomplished was to give Davout sufficient time to deploy his forces to block further deployment of the Prussian elements to his rear. By now the road behind could only be described a massed traffic jam as the Prussian divisions jockeyed to deploy forward.

The problem was further exacerbated as the flinty sixty-year-old hussar General, by the name of Blucher, pushed his unit to the front. Unsupported, he conducted furious charges against the French flank, but was beaten off with heavy losses. As successive Prussian units came into action, Davout fed his trailing divisions into the battle, always keeping just one step ahead of the desperate Prussians.

As the Prussian divisions of Orange and Wartensleben, supported by the cavalry and Guard infantry, made one final determined effort on the French left, Davout was forced to commit his last unit, the division of General Morand, into the fray. Why did the "Iron Marshal" have no further reserves to call on? Simply stated, the 20,000 men of Bernadotte's I Corps, who could have come to his support, were now busily counter- marching to the south. Bernadotte was later to receive the ire of his Emperor for this inexplicable action (a case of following orders with no flexibility).

As the final Prussian effort was ground to a halt by the advance of Morand's division, Prussian determination at last began to falter, partially because it had now become known that both Brunswick and Schmettau had fallen. Frederick William, himself, now took command of the Hohenzollern army. At around noon, he ordered one last assault on the shaken French left. Having no more reserves to bolster this flank, Davout rode to the site personally to rally his men. It proved to be just enough! By 1230 hrs., the spirit of the Prussian army had died.

Realizing that his army was crumbling, Frederick William lost heart and ordered the retreat from Auerstadt. The order was superfluous but the King hoped to fall back on Hohenlohe for support. From that quarter, however, there was to be no support, only the wreck of a dispirited army pouring west across turnip patches and potato fields through Weimar, every man for himself. On the other side of the Ilm River, the two streams of fugitives intermingled, rendering impossible any positive control by their commanders. Once the elaborate apparatus of discipline was demolished, the primordial instinct for survival reasserted itself and each man bent his remaining energy to ensuring that he remained a survivor rather than becoming a casualty. A proud army had lost its title to greatness; an era was conclusively ended. [14]

At Auerstadt, Davout had faced and defeated the main Prussian army of over 60,000 men. His losses had been heavy, over 8,000 men. But the Prussians had lost over 12,000 killed and wounded, 3,000 prisoners, and 115 guns. The pursuit that was to follow remains one of the classics of such operations in the annals of warfare. in three weeks of unrelenting maneuver, battle, and forced- marches, the French gathered 140,000 prisoners, 250 flags, and 800 field guns. Except for the units in East Prussia and Silesia, the long-feared Prussian Army ceased to exist, and the heir of Frederick the Great had been totally humiliated.

Recapitulation

Now for a brief recapitulation, not of the course of the battle itself, but relating how some of the events in the battle point out succinctly the various weaknesses of the Prussian army as mentioned in our first article.

Of prime importance was the ineffectual leadership provided by an over-aged and tradition-riddled officer corps. Overall leadership was nothing less than abysmal. But even worse, the Prussian tendency to rely on methodism developed under Frederick the Great proved a major deficiency. The fire-fight on the outskirts of Vierzehnheiligen provides a case in point. With absolutely no skirmishers deployed, 20,000 Prussians stood in the open for two hours conducting volley fire while the French sniped at them from behind cover.

The fact that the Prussian army consisted of nearly 40% foreign mercenaries, and that the remainder were "reservist" cantonists contributed greatly to the rapid disintegration of the army once the battle was lost. Contributing to this also was the overly harsh system of discipline that was extant in the Prussian army. Jornini writes in this regard, "Commanders cannot depend on discipline alone, but must instill in their soldiers a cohesion based upon mutual respect, an "espirit de corps", upon which both officer and soldier alike can depend in the darkest hour of battle." [15] Such sentiment was missing in the Prussian army of 1806.

The mobility of the Prussian army, adversely effected by the cumbersome supply services, also played a significant role in the outcome of the battles. The Prussians were slow to consolidate after the initial French onslaught, and could not even hope to out march the rapid moving French elements. The lack of adequate supplies in the Jena area also contributed greatly to the demoralization of the Prussian army long before the battle began.

Prussian artillery proved to be inferior to the French, both in employment and effectiveness. Nor did the Prussians have an appreciation for massed artillery support such as Napoleon utilized with his 25-gun battery situated on the Landgrafenberg. This might well be considered the forerunner of one of Napoleon's favorite tools of war-the Grand Battery.

Also significant was the lack of light troops with the Prussian army. Many of the fusilier battalions were detached from the main army on special duties during the battle. Of the 24 such battalions, only 10 were engaged in the double battles. Light troops screening for the Prussian forces in the defiles around Iserstadt or for the forces advancing on Vierzehnheiligen might well have given the French a nasty time of it. As it was, the Prussians were incapable, for the most part, in dealing with the French "tirailleur" tactics.

Lastly, the lack of appreciation among the Prussian hierarchy for the "combined arms concept" detracted greatly to the overall performance at Jena/Auerstadt ' Unsupported and piecemeal attacks, such as were conducted by Ruchel, Blucher and Hohenlohe, no matter how enthusiastically pressed by their commanders ' were doomed to failure. Only with the proper coordination of infantry, cavalry and artillery could the Prussians have hoped for success against the flexible French tactics.

Jena/Auerstadt provides a great lesson for even modern-day military professionals, this being that armies can never afford to become entrenched in the traditions and methodology of the past, but must be responsive to progressive changes of the present and future. The Prussian army, reincarnated after Tilsit, would reflect many of these reforms.
