The resumed siege was not without its problems. To move swiftly against Wurmser, Napoleon had abandoned his all his siege equipment, leaving it at Mantua. When he resumed the siege, it was much less effective without his guns. Furthermore, by early September, many of the scattered Austrian units had rejoined Wurmser's column. Even so, at the Battle of Bassano on 8 September, the Austrians were outnumbered almost two to one by the French. As the Austrian army retreated, Bonaparte ordered a pursuit that caused the Austrians to abandon their artillery and baggage. Most of the third battalion of the 59th "Jordis", and the first battalion of the Border Infantry Banat were captured and these units ceased to exist after this battle. The Austrians lost 600 killed and wounded, and 2,000 captured, plus lost 30 guns, eight colors, and 200 limbers and ammunition wagons. Wurmser's column fought its way to besieged Mantua, but emerged suddenly, in an effort to escape, at the Battle of La Favorita near there on 15 September. This was the second attempt to relieve the fortress; as the Austrians withdrew from the battle, they retreated into Mantua itself, and from 15 September until 2 February 1797, Wurmser was trapped inside the fortress while the city was besieged.
