Short answers, pulled from the story.
The Habsburg Austrian forces won the Battle of Caldiero on the 12th of November 1796. The Austrian army, initially led by Generalmajor Prince Friedrich Franz Xaver of Hohenzollern-Hechingen and later reinforced by additional brigades, repelled the French assault and forced Napoleon Bonaparte's divisions back into Verona.
The French suffered 1,000 killed and wounded, plus 800 men and two artillery pieces captured, for a total of approximately 1,800 losses. The Austrians lost 950 killed and wounded and 350 captured.
Several factors combined against the French. A violent rain and hailstorm blew into the faces of French troops, making it difficult to prime their muskets. Austrian reinforcements under Generalmajore Adolf Brabeck and Anton Schübirz von Chobinin arrived in the afternoon and pushed back Masséna's division, while Provera drove back Augereau on the other flank.
The Battle of Caldiero was part of the third Austrian attempt to relieve the Siege of Mantua during the War of the First Coalition, itself a phase of the broader French Revolutionary Wars. Two Austrian forces converged on Mantua, with Alvinczi advancing from the east and Davidovich from the north.
After withdrawing into Verona following the defeat at Caldiero, Bonaparte stripped forces from Generals Vaubois and Kilmaine and launched a new offensive. He defeated the Austrian army under Alvinczi at the Battle of Arcola on the 15th to the 17th of November 1796, reversing the setback of Caldiero.
Caldiero is a town located approximately 15 kilometres east of Verona in northern Italy. Its importance in 1796 stemmed from its position on the route Alvinczi's Austrian army was using to advance on Verona, which was the key French position guarding the road to the besieged city of Mantua.
