TheBattle of Kaiserslautern (28–30 November 1793) saw a Coalition army underCharles William Ferdinand, Duke of Brunswick-Wolfenbüttel oppose aRepublican French army led byLazare Hoche. Three days of conflict resulted in a victory by thePrussians and theirElectoral Saxon allies as they turned back repeated French attacks. TheWar of the First Coalition combat was fought near the city ofKaiserslautern in the modern-day state ofRhineland-Palatinate,Germany, which is located about 60 kilometres (37 mi) west ofMannheim.
In theFirst Battle of Wissembourg, the Coalition army ofDagobert Sigmund von Wurmser broke through the frontier defenses and drove the FrenchArmy of the Rhine south toStrasbourg. In response to this crisis, the French government appointed Hoche to command theArmy of the Moselle andJean-Charles Pichegru to lead theArmy of the Rhine, while urging them to relieve thesiege 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 inAlsace. The next engagement was theBattle of Froeschwiller in December.
The 36,850-man Coalition army ofCharles William Ferdinand, Duke of Brunswick successfully concluded thesiege 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 internalWar in the Vendée. During the siege, the French suffered approximately 4,000 casualties while the Coalition lost about 3,000.[1] The 60,000-strongArmy of the Rhine underAlexandre de Beauharnais and the 40,000-strongArmy of the Moselle underJean 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, theArmy of the Rhine toWissembourg and theArmy of the Moselle to theSaar 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 byBalthazar Alexis Henri Schauenburg on 5 August. Beauharnais was executed byguillotine on 23 July 1794.[3] His widowJoséphine de Beauharnais later marriedNapoleon Bonaparte.[4]
Landremont was soon ordered to send 12,000 soldiers to theArmy 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 underJean-Charles Pichegru.[5] Brunswick pressed forward toward the fortress ofBitche, driving back theCorps of the Vosges and theArmy 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 theCorps of the VosgesJean 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 thesiege of Landau. Pichegru was offered command of theArmy 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 theArmy 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 byDagobert Sigmund von Wurmser defeated Carlenc's 34,400-strong army in theFirst Battle of Wissembourg. The government ordered Carlenc's arrest on the 23rd.[8] TheArmy of the Rhine withdrew to the Zorn River nearStrasbourg while Wurmser's army occupied northernAlsace.[9] On 22 October, Delauney sent six battalions toSaverne where they helped repel an attack by one of Wurmser's divisions.[10] Pichegru took command of theArmy of the Rhine on 29 October.[11] That same day Delaunay was dismissed from command of theArmy of the Moselle. Therepresentatives on mission wantedEustache Charles d'Aoust to replace Delauney butLazare Hoche arrived fromParis to take command on 31 October. His rank wasgeneral 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 theBattle of Haguenau.[13]
The French government reinforced theArmy of the Moselle with 15,000 troops taken from theArmy of the Rhine and 5,000 from theArmy of the Ardennes. Both Hoche and Pichegru were well aware that the main objective was the relief ofLandau. In mid-November 1793, Hoche advanced from the Saar with 36,000 troops while the rest of the army guarded the passes through theVosges. Hoche used rough language with his subordinates; at this time he wrote one of his division commandersJean-Jacques Ambert, "Listen, bugger of asans-culotte...".[14] On 17 November, a Prussian raid on the fort atBitche 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 ofAlexandre Camille Taponier and Louis Pierre Huet bumped into 13,000 Prussians underFriedrich Adolf, Count von Kalckreuth at Biesingen, north ofMandelbachtal. 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 enteredBlieskastel on 18 November. The Prussians abandoned the camp ofHornbach 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 viaPirmasens, Brunswick made up his mind to offer battle atKaiserslautern.[14] In fact, Hoche hoped to raise the siege of Landau by striking east fromZweibrücken (Deux-Ponts) and then down theQueich 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 throughNeunkirchen am Potzberg andReichenbach-Steegen towardOtterberg, north of Kaiserslautern. On the right, Taponier marched directly on Kaiserslautern viaLandstuhl, with instructions to seize the Hoheneck heights. Hoche with the main body advanced throughSchönenberg-Kübelberg towardRodenbach. Rémy Vincent was posted in Pirmasens to watch the Prussians and to shield the army's movement.[16]
The Duke of Brunswick's army consisted of 35¾ battalions, 54 squadrons and 10 artillery batteries, a total of 26,000 Prussians, Saxons and allies. There were three Prussian divisions led byGeneral-Leutnants Ludwig Karl von Kalckstein,Nikolaus Heinrich von Schönfeld andFriedrich Adolf, Count von Kalckreuth, one Saxon division, an Advanced Guard led byColonel Szekely and a Guards brigade underGeneral-major Friedrich Adrian von Roeder.

The army artillery train was made up of 26 6-pound cannons in four foot batteries, eight 12-pound cannons in one foot battery and one battery of eight mortars.[17]
Lazare Hoche'sArmy of the Moselle numbered 29,115 infantry, 5,046 cavalry and 52 field guns.[17] These were organized into an Advance Guard underGeneral of BrigadePaul-Alexis Dubois and divisions underGenerals of Division Ambert, Huet, Taponier and Vincent. In the list that follows, the numbered units are regulars while the italicized units areNational Guard volunteer battalions and free companies. The Advance Guard included one company of the 89th Line Infantry, theGérard,Guillaume,Louvre andMetz Free Companies, four squadrons each of the 1st Carabinier and 1st Dragoon Regiments, three squadrons of the 3rd Hussars, one squadron of the 7th Hussars, a half squadron each of theJemappes Hussars and the 6th and 16thChasseurs à Cheval and 12 guns in two horse artillery batteries.[15]
Ambert's division was organized into brigades underJean-Baptiste Olivier, Henri Simon and Joinville. Olivier led one battalion of the 13th Line Infantry, one battalion and four squadrons of theMoselle Legion, four squadrons of the 2nd Carabinier Regiment and six guns in one horse artillery battery. Simon commanded the 1st Battalion of the 30th Line, the 2nd Battalion of the 55th Line, the 3rd Battalion of theRépublique, the 4th Battalions of theHaute-Saône andMeurthe and the 5th Battalion of theOrne. The Joinville brigade comprised the 2nd Battalion of the 99th Line and one battalion of theJoinville. Huet's division was divided into brigades led byAntoine Morlot and Nicolas Augustin Paillard. Morlot directed the 1st Battalions of the 44th and 81st Line, the 2nd Battalion of the 71st Line, the 1st Battalion of theArdennes, the 2nd Battalion of theHaute-Marne, the 6th Battalion of theMeurthe and 16 guns in two foot artillery batteries.

Vincent's advance guard included one battalion of theChasseurs de Rheims, five squadrons each of the 1st Chasseurs à Cheval and Gendarmerie Regiments and six guns in one horse artillery battery.[15]
Brunswick's army was deployed with its right flank resting on the city of Kaiserslautern and its flank covered by the marshy banks of theLauter 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 atLauterecken well to the north. Another division was posted atTrippstadt to the south. The Trippstadt force maintained communications withFrederick Louis, Prince of Hohenlohe-Ingelfingen's corps near Pirmasens. Hohenlohe blocked the eastward routes to Landau viaNeustadt an der Weinstrasse andAnnweiler am Trifels. Another Prussian corps underWilhelm 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 ofWissembourg. Military theoristAntoine-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 Taponier leading the right, Hoche the center and Ambert the left. Taponier moved against the village of Vogelweh while Ambert aimed to cross the Lauter atHirschhorn. Taponier's column was the first to encounter the Prussians and to open the battle, meeting moderate success. The initial attack carried his troops onto the outer ridge of the Hoheneck heights.[19] Taponier also came up against the Galgenberg (Gallows Hill) which was defended by a Prussian redoubt.[9] Alarmed at the march of Ambert's column, Brunswick reacted by sending Kalckreuth north to block it. Kalckreuth's force took a new position with his left flank on the Lauter, his center at Morlautern and his right near Erlenbach. Another division was placed on the Kaiserberg, whileDuke Karl August of Saxe-Weimar was left to defend the western approaches to Kaiserslautern.[19]
After leaving Rodenbach, Hoche's column encountered impassable roads in the Voog Forest and had to detour around the obstacle. His troops stayed on the west bank of the Lauter and never got into action on the 28th. By strenuous efforts, Ambert crossed the Lauter and moved south through Katzweiler and Sambach. He gamely attacked across the Otterbach stream several times but his 6,000 men were outnumbered by Kalckreuth. Menaced with encirclement, Ambert retreated and came in close proximity to Hoche's center column near Sambach. Despite the lack of success, Hoche determined to deliver the main attack from his left wing the next day. Accordingly, he made preparations to cross the Sambach bridge to join Ambert.[20]
The next day the French army crossed the river in force. On the 29th, Dubois' advance guard crossed first and joined a brigade under Olivier in a costly attack on the Prussian entrenchments.[20] Meanwhile, Hoche established a 16-gun battery near Sambach[9] and a second battery near Erfenbach on the west bank. Ambert led the brigades of Simon and Paillard far to the left to turn the Prussian position at Otterberg. Huet moved against the enemy position with Morlot's brigade.[20] Under the crossfire of the Sambach and Erfenbach batteries, the Prussians fell back and the French crossed the Otterbach.[21]

Hoche set up a 29-gun battery on the Osterberg height, starting a mutual bombardment that went on for a few hours. The French general then hurled a column of 10,000 troops at the Prussian left flank.[21] This part of Kalckreuth's position between the Lauter and Morlautern was separated from the rest of his line by a ravine. Two regiments of Saxon cavalry charged[22] Huet's division in the left flank. Hoche'schief of staffGabriel Marie Joseph, comte d'Hédouville brought up some French cavalry squadrons from the Osterberg and hit the Saxons in their right flank.[23] More horsemen from both sides joined the melee and ultimately the Saxons prevailed.[22] Shaken by the cavalry charge, the French infantry withdrew to the Otterbach valley. The French attacks on Erlenbach also failed and by 6:00 PM the fusillade died down.[21]
On the left flank, Simon's brigade got lost and was unable to join Paillard's brigade at the old Otterberg glassworks until that evening. By then it was too late to mount an attack, so the 29th was Ambert's day to miss the action. Ambert had to march all night to rejoin the French main force. Unknown to the French, Kospoth's division marched south from Lauterecken toSchallodenbach, from which the Prussian could attack Ambert in the rear. So it was lucky that the French left wing shifted position.[22] On the right flank Taponier assaulted the Galgenberg but was unable to make any headway. The Prussian left wing was supported by artillery fire from the Kaiserberg. Brunswick directed Wartensleben at Trippstadt to march to Kaiserslautern with three battalions and 10 squadrons. During the day, Wartensleben's troops reinforced the Duke of Saxe-Weimar's position on the Galgenberg and helped drive Taponier's men back into the woods.[24]
Hoche persisted in his attacks on 30 November. At dawn, he directed his artillery to open a new barrage on the Prussian positions.[21] On the left flank, leading four battalions against the Buchberg near Erlenbach,Gabriel Jean Joseph Molitor failed to capture the position and was repulsed after a sanguinary fight with the Saxons. The appearance of Kospoth's troops near Otterberg in his rear compelled Molitor to make a rapid retreat.[24] The French assaulted the Galapfelberg height but this effort was also defeated.[21] This feature is located north of the Kaiserberg.[25] While holding the woods in the center, the division of Huet had difficulty maintaining its position, suffering under a storm ofgrapeshot. The cavalry of both armies was very active; the fighting took the form of charges and counter-charges of the French and Saxo-Prussian cavalry.[24] On the French right, Taponier made two more assaults on the Galgenberg, but Saxe-Weimar drove them off.[21]
After having secured his flanks, the Duke of Brunswick launched a counterattack against the Osterberg.[24] Seeing his left wing outflanked by the Saxons near Erlenbach, Hoche ordered a retreat. He detailed Ambert and five battalions to cover the withdrawal from the Mayberg height while the army filed to the west bank across the Sambach bridge and another span built near the Lamperts mill. Hoche's exhausted troops retreated to Zweibrücken, Hornbach and Pirmasens.[26] Following the passive strategy of his sovereign,King Frederick William II, Brunswick did not launch a pursuit.[17]
Jomini estimated that the French suffered 3,000 casualties while the Saxo-Prussians lost 1,300.[26] A second authority asserted that the French lost 1,300 killed and wounded plus an additional 700 men, two guns and one color captured, adding that Brunswick's army sustained losses of 44 officers and 785 soldiers killed and wounded, a total of 829.[14] A third source listed French losses as 2,400 killed and wounded with 700 men, two guns and one color captured, while the Prussians lost 32 officers and 584 men and the Saxons lost 12 officers and 178 men, a total of 806.[17]
Therepresentatives on mission were angry at Hoche and threatened to denounce him. He sarcastically told them to write an order declaring victory, then he went on, "Do not disturb yourselves, I have other means". Fortunately for him, Hoche remained in favor with theCommittee of Public Safety and was not arrested and executed like Custine and Houchard.Maximilien Robespierre declared that Hoche's behavior showed that he was a truesans-culotte and another 10,000 reinforcements were sent him from theArmy of the Ardennes. However, Hédouville who Hoche had kept as chief of staff for the battle was arrested as a nobleman.[27]François Joseph Lefebvre was promoted togeneral of brigade for excellent work, as was Édouard Huet for repelling the Prussian assault at Bitche. Louis Huet had shown himself incompetent and was shelved.[28]
Brunswick seemed baffled by Hoche's clumsy attack on his army. In his subsequent actions the Prussian failed to fully cooperate with his colleague Wurmser.[28] Despite its defeat, the morale of theArmy of the Moselle was unaffected. The French soldiers remained sure of themselves, perhaps because of their capture of enemy-held territory before the battle. Hoche fortified Pirmasens and Blieskastel and mounted a false attack against Brunswick. But this was a smokescreen to cover his real intentions which were to shift his strength against Wurmser's western flank. Already on 23 November, Philippe-Joseph Jacob's division was moved toNiederbronn-les-Bains. This was joined by Taponier's division on 5 December and Jean Grangeret's division a week later.[28] On 22 December 1793, Hoche defeated Wurmser in theBattle of Froeschwiller.[29]
