Bonaparte's concentration of three divisions overwhelmed Davidovich at the Battle of Rovereto on 4 September. Leaving Vaubois in Trento to watch the remnants of Davidovich's corps, Bonaparte boldly decided to cut loose from his supply line and follow in Wurmser's wake. He directed Masséna and Augereau east through Levico and Borgo, then south down the Brenta valley. Augereau dispersed the Austrian rearguard at Primolano on 7 September. The two French divisions fell upon Wurmser and beat him badly at the Battle of Bassano on 8 September. Instead of retreating to the east, Wurmser joined the division of Mészáros and headed west for Mantua with Bonaparte in hot pursuit. Hoping to annihilate his adversary before he reached Mantua, the French commander sent Augereau to Padua to prevent Wurmser from escaping to the east and Masséna through Vicenza and Arcole.
