In the Battle of Castiglione on 5 August 1796, the French Army of Italy under the command of General Napoleon Bonaparte defeated an Austrian army led by Field Marshal Dagobert Sigmund von Wurmser. Castiglione and the Battle of Lonato were the major actions in a campaign which marked the first attempted relief of the Siege of Mantua. While Wurmser advanced east of Lake Garda with three columns, Peter Quasdanovich moved his column into the area west of Lake Garda. The Austrians pushed back the French forces and forced Bonaparte to raise the siege. However, the French commander massed against Quasdanovich and forced him to retreat after a week of see-saw fighting. After disposing of Quasdanovich, Bonaparte turned on Wurmser and defeated the main army also. In the sequel, the French pushed the Mantua garrison back and blockaded the city.
