retreat. After Dagobert von Wurmser's defeat at the Battle of Bassano on 8 September, Ott led the Austrian advance guard with great distinction during Wurmser's dash to Mantua. At Cerea, he held off a French intercepting column long enough for Wurmser to arrive and defeat it. The next day, Ott ambushed the 12th Light Demi-Brigade, killing its commander, Brigadier General Charles-François Charton and capturing 400 men. During the battle under the walls of Mantua on 15 September, he commanded the left flank at La Favorita. His force was the last part of the Austrian army to retreat. He led a sortie on 23 September which suffered heavy losses at Governolo. In February 1797, he surrendered with the garrison at the unsuccessful conclusion of the Siege of Mantua.

In the bitterly fought Battle of Montebello on 9 June, a French force led by Jean Lannes defeated Ott's corps. He had fought the battle against orders. When the Austrian chief of staff begged him to withdraw at the beginning of the action, Ott replied, "My outposts are attacked. I march to succor them." At the Battle of Marengo on 14 June, Ott commanded the Austrian left wing. Because of congestion in the bridgehead, it took a long time for the left wing to deploy. However, once his attack at mid-day got underway, it broke the French right flank and helped convince them to retreat from Marengo. Later in the battle, when French reinforcements defeated the Austrian main body, Ott withdrew in good order and brought his command off in safety. This was his
