The Battle of Kaiserslautern (28–30 November 1793) saw a Coalition army under Charles William Ferdinand, Duke of Brunswick-Wolfenbüttel oppose a Republican French army led by Lazare Hoche. Three days of conflict resulted in a victory by the Prussians and their Electoral Saxon allies as they turned back repeated French attacks. The War of the First Coalition combat was fought near the city of Kaiserslautern in the modern-day state of Rhineland-Palatinate, Germany, which is located about 60 kilometres (37 mi) west of Mannheim.

In the First Battle of Wissembourg, the Coalition army of Dagobert Sigmund von Wurmser broke through the frontier defenses and drove the French Army of the Rhine south to Strasbourg. In response to this crisis, the French government appointed Hoche to command the Army of the Moselle and Jean-Charles Pichegru to lead the Army of the Rhine, while urging then to relieve the Siege of Landau. In November, Hoche launched an offensive which pressed back the Duke of Brunswick's army to Kaiserslautern. On 28 November, French troops moved on Brunswick's defenses from the north, northwest and west, but for two days the Coalition army fended off the piecemeal attacks of their adversaries. Hoche finally got his entire army into action on the 30th, but the professional Prussian soldiers proved more than a match for the enthusiastic but indifferently-trained French. After the setback, Hoche changed his strategy and turned a large part of his army against Wurmser's exposed western flank in Alsace. The next engagement was the Battle of Froeschwiller in December.

Duke of Brunswick

The 36,850-man Coalition army of Charles William Ferdinand, Duke of Brunswick successfully concluded the Siege of Mainz on 23 July 1793. The French garrison of 18,675 men surrendered and was released on the promise of not fighting the Coalition for one year. The French government immediately sent the released troops to fight in the internal War in the Vendée. During the siege, the French suffered approximately 4,000 casualties while the Coalition lost about 3,000.[1] The 60,000-strong Army of the Rhine under Alexandre de Beauharnais and the 40,000-strong Army of the Moselle under Jean Nicolas Houchard were poised to march to the relief of Mainz. However, Beauharnais had not informed the Mainz garrison that help was on the way and then took too long to start his movement.[2] After the fall of Mainz, both French armies retreated, the Army of the Rhine to Wissembourg and the Army of the Moselle to the Saar River. Blamed for the loss of Mainz, Beauharnais fell into a funk, begged to be relieved of command and on 23 August 1793 he was replaced by Charles-Hyacinthe Le Clerc de Landremont. Meanwhile, Houchard had been replaced by Alexis Balthazar de Schauenburg on 5 August. Beauharnais was executed by guillotine on 23 July 1794.[3] His widow Joséphine de Beauharnais later married Napoleon Bonaparte.[4]

Landremont was soon ordered to send 12,000 soldiers to the Army of the North. This reduced the strength of his field force to 45,000 with an additional 39,000 in garrisons or in the Upper Rhine Division under Jean-Charles Pichegru.[5] Brunswick pressed forward toward the fortress of Bitche, driving back the Corps of the Vosges and the Army of the Moselle. At this moment, the French government dismissed Schauenburg for the crime of being an aristocrat. During his short tenure he had drilled the troops into better shape. The late commander of the Corps of the Vosges Jean René Moreaux was named to succeed him, but declined because an old wound had reopened.[6] A division commander, Jacques Charles René Delauney reluctantly took over the army on 30 September.[7] Landremont was also dismissed and arrested but his intended replacement, Antoine Guillaume Delmas was trapped in the Siege of Landau. Pichegru was offered command of the Army of the Rhine but he refused. Since the generals saw that leading the army led to arrest or execution, none wanted to accept the command. Finally on 2 October, Jean Pascal Carlenc took command of the Army of the Rhine. He would quickly prove to be completely unfitted for the job.[6]

On 13 October 1793, a 43,185-man Coalition army led by Dagobert Sigmund von Wurmser defeated Carlenc's 34,400-strong army in the First Battle of Wissembourg. The government ordered Carlenc's arrest on the 23rd.[8] The Army of the Rhine withdrew to the Zorn River near Strasbourg while Wurmser's army occupied northern Alsace.[9] On 22 October, Delauney sent six battalions to Saverne where they helped repel an attack by one of Wurmser's divisions.[10] Pichegru took command of the Army of the Rhine on 29 October.[11] That same day Delaunay was dismissed from command of the Army of the Moselle. The representatives on mission wanted Eustache Charles d'Aoust to replace Delauney but Lazare Hoche arrived from Paris to take command on 31 October. His rank was general of division rather than army commander because he was supposed to act under the orders of Pichegru.[12] On 18 November, Pichegru began a series of attacks on Wurmser's defensive lines in the Battle of Haguenau.[13]

The French government reinforced the Army of the Moselle with 15,000 troops taken from the Army of the Rhine and 5,000 from the Army of the Ardennes. Both Hoche and Pichegru were well aware that the main objective was the relief of Landau. In mid-November 1793, Hoche advanced from the Saar with 36,000 troops while the rest of the army guarded the passes through the Vosges. Hoche used rough language with his subordinates; at this time he wrote one of his division commanders Jean-Jacques Ambert, "Listen, bugger of a sans-culotte...".[14] On 17 November, a Prussian raid on the fort at Bitche failed. Leopold Alexander von Wartensleben's column of 1,200 picked soldiers overran the outer defenses with the help of a French traitor. However, they were soon discovered and repulsed with casualties of 120 killed and 251 captured. The French lost 63 men captured and few other losses. The same day, the French divisions of Alexandre Camille Taponier and Louis Pierre Huet bumped into 13,000 Prussians under Friedrich Adolf, Count von Kalckreuth at Biesingen, north of Mandelbachtal. The 20,000 French troops were drubbed, losing 760 men killed or wounded and 42 captured against a Prussian loss of only 16 killed and 92 wounded.[15]

Despite the setback at Biesingen, Brunswick's troops were pulling back into winter quarters and Hoche entered Blieskastel on 18 November. The Prussians abandoned the camp of Hornbach and the French occupied it on the 19th. Believing that he had his enemies on the run, Hoche became very optimistic. Alarmed at the French offensive and anxious that they intended to relieve Landau by moving via Pirmasens, Brunswick made up his mind to offer battle at Kaiserslautern.[14] In fact, Hoche hoped to raise the siege of Landau by striking east from Zweibrücken (Deux-Ponts) and then down the Queich River.[9] Meanwhile, Hoche completely lost track of his enemies. From Zweibrücken he launched his army toward Pirmasens on the 24th only to have to march back to his starting point the next day when he did not find Brunswick. Finally, the French started northeast for Kaiserslautern in three columns. On the left, Ambert moved through Neunkirchen am Potzberg and Reichenbach-Steegen toward Otterberg, north of Kaiserslautern. On the right, Taponier marched directly on Kaiserslautern via Landstuhl, with instructions to seize the Hoheneck heights. Hoche with the main body advanced through Schönenberg-Kübelberg toward Rodenbach. Rémy Vincent was posted in Pirmasens to watch the Prussians and to shield the army's movement.[16]

First day[edit]

Brunswick's army was deployed with its right flank resting on the city of Kaiserslautern and its flank covered by the marshy banks of the Lauter River. Just to the north, a regiment was stationed on the castle hill at Otterberg in order to maintain a link with Ernst Christian von Kospoth's division at Lauterecken well to the north. Another division was posted at Trippstadt to the south. The Trippstadt force maintained communications with Frederick Louis, Prince of Hohenlohe-Ingelfingen's corps near Pirmasens. Hohenlohe blocked the eastward routes to Landau via Neustadt an der Weinstrasse and Annweiler am Trifels. Another Prussian corps under Wilhelm René de l'Homme de Courbière operated in the Rhine valley, supporting Wurmser's army and covering the passes in the Vosges. Finally, a brigade under Leopold Heinrich von der Goltz guarded the Pigeonnier height west of Wissembourg. Military theorist Antoine-Henri Jomini commented that Brunswick ought to have massed all these forces against Hoche. He also faulted Hoche for attacking in three separated columns.[18]

On 28 November the French army advanced in three columns against the Prussian position, with Alexandre Camille Taponier leading the right, Hoche the center and Jean-Jacques Ambert the left. Taponier's column was the first to encounter the Prussians and to open the battle, meeting moderate success. On the left, Ambert encountered problems crossing the Lauter with his 6,000 men and was soon faced by the corps of Kalckreuth which heavily outnumbered him. Menaced with encirclement, Ambert retreated and rejoined Hoche's center column.

Second day[edit]

The next day, having located the Prussians, the French army crossed the river in force. The advance force led by the generals Edmond Dubois de Crance and Gabriel Jean Joseph Molitor became stuck on the plateau of Erlebach and had to be rescued by Ambert. Hoche reformed his troops on the Otterberg and unsuccessfully attacked the Prussian left with several squadrons of cavalry. In the confusion several French units lost their way in the terrain and Ambert had to march all night to rejoin the French main force. On the right flank Taponier attacked Kaiserslautern but encountering stiff resistance he was pushed back into the woods.

Third Day[edit]

After a heavy morning cannonade, Hoche launched new piecemeal attacks on the Prussians. On the left flank, leading four battalions against the Buchberg, Molitor failed to capture the position and was repulsed. On the French right flank the division of Louis Pierre Huet had difficulty maintaining its position. In the center, the fighting took the form of charges and counter-charges of the French and Prussian cavalry. After having secured his flanks, the Duke of Brunswick launched a counterattack against the Otterberg and Hoche ordered a retreat, having lost 3,000 men in the course of the battle. As the Prussians did not follow up their success, the French army was able to retreat back towards the Moselle River.
