The campaign of 1796 was part of the French Revolutionary Wars in which republican France pitted itself against a fluid coalition of Prussians and Austrians and several other states of the Holy Roman Empire, the British,
Sardinians, Dutch and royalist French emigres. The French had won several victories but the campaigns of 1793 through 1795 had been less successful. The Coalition partners had difficulty coordinating their war aims and their efforts faltered. In 1794 and 1795, French victories in northern Italy salvaged French enthusiasm for the war and forced the Coalition to withdraw further into Central Europe. At the end of the Rhine Campaign of 1795, the
Habsburg Coalition and the
French Republicans called a truce between their forces that had been fighting in Germany. The agreement lasted until 20 May 1796, when the Austrians announced that the truce would end on 31 May. The Austrian Army of the Lower Rhine included 90,000 Habsburg and Imperial troops. The 20,000-man right wing, first under
Duke Ferdinand Frederick Augustus of Württemberg, then later under
Wilhelm von Wartensleben, stood on the east bank of the Rhine behind the
Sieg River, observing the French bridgehead at Düsseldorf. The garrisons of
Mainz Fortress and
Ehrenbreitstein Fortress included 10,000 more. The remainder of the Imperial and Coalition army, the 80,000-strong Army of the Upper Rhine, secured the west bank behind the
Nahe River. Commanded by
Dagobert Sigmund von Wurmser, this force anchored its right wing in
Kaiserslautern on the west bank, while the left wing under
Anton Sztáray,
Michael von Fröhlich and
Louis Joseph, Prince of Condé guarded the Rhine from Mannheim to
Switzerland. The original Austrian strategy was to capture
Trier and to use their position on the west bank to strike at each of the French armies in turn. After news arrived in Vienna of
Napoleon Bonaparte's successes in northern Italy, Wurmser was sent to there with 25,000 reinforcements and the
Aulic Council gave
Archduke Charles command over both Austrian armies in the Rhineland and ordered him to hold his ground. Two French armies opposed the Imperial and Coalition troops.
Jean Victor Moreau's commanded both armies, but the northern army, Sambre and Moselle, was large enough for a sub command: Jourdan. The 80,000-man Army of Sambre and Meuse held the west bank of the Rhine down to the Nahe and then southwest to
Sankt Wendel. On the army's left flank,
Jean Baptiste Kléber had 22,000 troops in an entrenched camp at Düsseldorf. The
Army of the Rhine and Moselle, directly commanded by Moreau, was positioned behind (west of) the Rhine from Hüningen, where
Pierre Marie Barthélemy Ferino commanded the furthest right wing, northward, along the
Queich River near
Landau, and with its left wing extended west toward
Saarbrücken. The far right wing under. The French plan called for a spring (April–May–June) offensive, during which two French armies would press against the flanks of the Coalition's northern armies in the German states and a third army approached Vienna through Italy. Jean-Baptiste Jourdan's army would push south from Düsseldorf, hopefully drawing troops toward themselves, while Moreau's army massed on the east side of the Rhine by Mannheim; a deft feint toward Mannheim caused Charles to reposition his troops. Once this occurred, Moreau's army executed a forced march south and, on 23 June, overwhelmed the bridgehead at Kehl. The Imperial troops there included only 7,000 troops recruited that spring from the
Swabian Circle polities; despite their lack of experience and training, they held the bridgehead for several hours before retreating toward
Rastatt. Moreau reinforced the bridgehead with his forward guard and his troops poured into Baden unhindered. In the south, by the Swiss city of Basel, Ferino's column moved quickly across the river and advanced (eastward) up the Rhine along the Swiss and German shoreline toward Lake Constance, spreading into the southern end of the Black Forest. Worried that his supply lines would be overextended or his army would be flanked, Charles retreated to the east. By the end of July, the entirety of the Swabian Circle, most of Bavaria, Franconia, Baden and Wuerttemberg had reached a separate peace with the French. which disarmed the Imperial army, and gave French free rein to demand supplies from the southern polities. With Charles absent from the north, Jourdan recrossed the Rhine and drove Wartensleben behind the Lahn river. The Army of Sambre and Meuse defeated its opponents at Friedberg, Hesse on 10 July, while Charles was busy at Ettlingen. Jourdan captured
Frankfurt am Main on 16 July. Leaving behind
François Séverin Marceau-Desgraviers with 28,000 troops to blockade Mainz and Ehrenbreitstein, Jourdan pressed up the Main River. Following Carnot's strategy, the French commander continually operated against Wartensleben's north flank, causing the Austrian general to fall back. Buoyed up by their forward movement and by the capture of Austrian supplies, the French captured
Würzburg on 4 August. Three days later, the Army of Sambre and Meuse, under the temporary direction of Kléber, won another clash with Wartensleben at
Forchheim on 7 August. Despite this success, though, the two French armies remained separated. The outnumbered French were driven north west through
Altdorf bei Nürnberg to the
Pegnitz River. Leaving
Friedrich Freiherr von Hotze with a division to pursue Bernadotte, the Archduke thrust north at Jourdan's right flank. The French fell back to
Amberg as Charles and Wartensleben's forces converged on the Army of Sambre and Meuse. On 20 August, Moreau sent Jourdan a message vowing to closely follow Charles, which he did not do. In the
Battle of Amberg on 24 August, Charles defeated the French and destroyed two battalions of their rear guard. The Austrians lost 400 killed and wounded out of 40,000 troops. Of a total of 34,000 soldiers, the French suffered greater losses of 1,200 killed and wounded plus 800 men and two colors captured. Jourdan retreated first to Sulzbach and then behind the
Regnitz river where Bernadotte joined him on 28 August. Hotze and his Habsburg troops reoccupied
Nürnberg and Jourdan, who had expected Moreau to keep Charles occupied in the south, found himself outnumbered. At this point, the petty jealousies and rivalries that had fostered in the Army over the summer came to a head. Jourdan had a spat with his wing commander Kléber and that officer suddenly resigned his command. Two generals from Kléber's clique, Bernadotte and Colaud, also made excuses to leave the army immediately. Faced with this mutiny, Jourdan replaced Bernadotte with General
Henri Simon and divided Colaud's rebellious units among the other divisions. Jourdan marched south with 30,000 men of the infantry divisions of Simon,
Jean Étienne Championnet,
Paul Grenier and with
Jacques Philippe Bonnaud's reserve cavalry. Lefebvre's division, 10,000-strong, remained at Schweinfurt to cover a possible retreat. The losses at Würzburg compelled the French to lift the siege of Mainz on 7 September and to move those troops to reinforce their lines further east. On 10 September, Marceau reinforced the Army of Sambre and Meuse with 12,000 troops that had been blockading the east side of Mainz.
Jean Hardy's division from the west side of Mainz retreated to the Nahe river and dug in. The French government belatedly recognized the difficulties in which the Army of the Sambre and Meuse struggled and transferred two divisions commanded by
Jacques MacDonald and
Jean Castelbert de Castelverd from the idle
Army of the North. MacDonald's division stopped at Düsseldorf while Castelverd's was placed in the French line on the lower Lahn. These reinforcements brought Jourdan's strength back to 50,000 but the French abandonment of the sieges at Mainz and later Mannheim and
Philippsburg, released about 27,000 Habsburg troops to reinforce Charles' now overwhelming numbers. Moreau continued in the south to press toward Vienna, seemingly oblivious to Jourdan's situation. Over the next few days, most of the Army of Sambre and Meuse returned to the west bank of the Rhine, except for a small rear guard. After his disastrous panic at Diez in which he prematurely abandoned a critical bridge position, Jean Castelbert de Castelverd held east bank entrenchments at Neuwied, Poncet crossed at
Bonn while the other divisions retired behind the Sieg river. Jourdan handed over command to
Pierre de Ruel, marquis de Beurnonville, on 22 September. Charles left 32,000 to 36,000 troops commanded by
Franz von Werneck in the north, 9,000 more in Mainz and Mannheim to insure the Army did not recross the Rhine, and moved south with 16,000 men to intercept Moreau. ==Reformation as the Army of Germany (1797)==
