After being released in a prisoner exchange, Ocskay led a brigade in Paul Davidovich's Tyrol Corps during the third attempt to relieve Mantua. During these operations, he fought in the action at Cembra on 2 November, the Battle of Calliano on 6–7 November, and the combat of Rivoli Veronese on 17 November. Before the latter action, he led his soldiers over snow-covered mountain trails to reach the battlefield. He then launched a successful attack that helped rout the French. These victories proved hollow when the French defeated the main Habsburg army at the Battle of Arcole on 15–17 November. On 22 November, Bonaparte fell on the Tyrol Corps with most of his strength and drove it back toward Trento.
