On 22 August 1796, Charles and Friedrich Joseph, Count of Nauendorf, encountered Bernadotte's division at Neumarkt. The outnumbered French were driven northwest through Altdorf bei Nürnberg to the river Pegnitz. Leaving Friedrich Freiherr von Hotze with a division to pursue Bernadotte, Charles thrust north at Jourdan's right flank. The French general 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 rearguard. The Austrians lost 400 killed and wounded out of 40,000 troops. Of a total of 34,000 soldiers, the French suffered losses of 1,200 killed and wounded plus 800 men and two colors captured. Jourdan retreated first to Sulzbach and then behind the river Wiesent where Bernadotte joined him on 28 August. Meanwhile, Hotze reoccupied Nürnberg. Jourdan, who had expected Moreau to keep Charles occupied in the south, now found himself facing a numerically superior enemy.
