The Second Battle of Bassano was fought on the 6th of November 1796 between a Habsburg army under Feldzeugmeister József Alvinczi and Napoleon Bonaparte's French Army of Italy, near Bassano del Grappa and Cittadella in Northern Italy. The Austrians repulsed persistent French attacks, with both sides suffering heavy losses. It was the first tactical defeat of Bonaparte's career.
Feldzeugmeister József Alvinczi commanded the Habsburg army overall. Key subordinates included Feldmarschall-Leutnant Peter Vitus von Quosdanovich, who led the 28,000-strong Friaul Corps, and Feldmarschall-Leutnant Giovanni Provera, who held the Austrian left flank near Fontaniva.
French casualties totalled 3,000, including 508 men and 1 howitzer captured. Austrian losses numbered 2,823, plus two cannons captured. Provera's left wing lost 208 killed, 873 wounded, and 109 captured; Quosdanovich's right wing suffered 326 killed, 858 wounded, and 449 captured.
The battle was part of the Austrian third attempt to relieve the siege of Mantua during the War of the First Coalition. Emperor Francis II had appointed Alvinczi to assemble a new field army after earlier relief attempts had failed, most recently when Bonaparte defeated Würmser at the Battle of Bassano on the 8th of September 1796.
The defeat placed Bonaparte in a dangerous position, as both arms of the Austrian two-pronged offensive threatened to encircle him, while Würmser's large garrison remained blockaded in Mantua behind him. Bonaparte unsuccessfully attacked at the Battle of Caldiero on the 12th of November before the campaign reached its climax at the Battle of Arcole on the 15th-the 17th of November.
One battalion of the Samuel Gyulai Infantry Regiment Nr. 32 suffered 390 casualties during the fighting around Bassano, which amounted to nearly 50 percent of its strength. The 2nd and 3rd battalions of Splényi Infantry Regiment Nr. 51 also suffered heavily at Fontaniva, losing 9 officers and 657 men out of 2,000 soldiers.
