For the third relief of Mantua, Emperor Francis II appointed József Alvinczi commander of a newly formed army. Alvinczi planned to advance on Mantua from the east with 28,000 soldiers while Davidovich and 19,500 troops moved from the Adige valley in the north. Davidovich's Tyrol Corps comprised the brigades of Sporck, Vukassovich, Johann Laudon, and Joseph Ocskay, plus a small reserve. After a bloody clash at Cembra on 2 November, he recaptured Trento. He routed Claude Vaubois' outnumbered French division at the Battle of Calliano on 7 November. Despite being urged by Alvinczi to attack again, he proved very slow to follow up his success. One reason was the 3,500 casualties suffered at Cembra and Calliano. Other difficulties included a false report that placed André Masséna's division in his front, heavy snow in the mountains, and the fact that messages took two days to arrive from Alvinczi. He routed Vaubois again at Rivoli Veronese on 17 November, but this victory came two days too late. After the French defeated Alvinczi on 15–17 November at the Battle of Arcole, Bonaparte turned on Davidovich in great strength. The French beat him in a second clash at Rivoli on 22 November. With Davidovich's corps in flight northward, Alvinczi was forced to abandon the campaign.
