The summer of 1796 saw the two French armies of Jourdan and Jean Victor Marie Moreau advance into southern Germany. They were opposed by Archduke Charles, who supervised two weaker Austrian armies commanded by Wilhelm von Wartensleben and Maximilian Anton Karl, Count Baillet de Latour. At the Battle of Amberg on 24 August, Charles managed to concentrate superior numbers against Jourdan, forcing him to withdraw. At Würzburg, Jourdan attempted a counterattack in a bid to halt his retreat. After his defeat, Charles forced Jourdan's army back to the Rhine. With his colleague in retreat, Moreau was isolated and compelled to abandon southern Germany.
