Dagobert Sigmund von Wurmser in the context of "Battle of Castiglione"

The siege of Mantua lasted from 4 June 1796 to 2 February 1797 with a short break where French forces under the overall command of Napoleon Bonaparte besieged and blockaded a large Austrian garrison at Mantua for many months until it surrendered. The siege was the focal point of the Italian Campaign of 1796-1797, lasting the vast majority of the campaign and being the hinge point that would determine which side would control Northern Italy. The eventual surrender, together with the heavy losses incurred during four unsuccessful relief attempts, led to Napoleon invading Austria and convincing the Austrians to sue for peace in 1797. The siege occurred during the War of the First Coalition, which is part of the French Revolutionary Wars. Mantua, a city in the Lombardy region of Italy, lies on the Mincio River.

After driving the Austrian army out of northwest and north-central Italy, the French invested the fortress of Mantua starting in early June 1796. In late July, a new Austrian commander, Dagobert Sigmund von Wurmser, led an army to the relief of Joseph Canto d'Irles's garrison from the north. Mantua was reached and the French were forced to abandon the siege. However, the Austrians were subsequently beaten in the battles of Lonato and Castiglione. Forced to retreat, Wurmser resupplied and reinforced the fortress with food and able-bodied troops. After withdrawing north up the Adige River, Wurmser planned to move his main army through the mountains to Bassano via the Brenta valley. From there he would mount the second relief of Mantua from the northeast. In an exceedingly bold maneuver, Bonaparte smashed Paul Davidovich's covering force and followed Wurmser down the Brenta valley. Overcoming the Austrian army at Bassano in early September, Bonaparte tried to destroy Wurmser but failed. Instead he chased the bulk of the Austrian army into Mantua. The garrison now counted 30,000 men, but cut off from outside help, disease and starvation began mowing down Wurmser's troops.

The Battle of Bassano was fought on 8 September 1796, during the French Revolutionary Wars, in the territory of the Republic of Venice, between a French army under Napoleon Bonaparte and Austrian forces led by Count Dagobert von Wurmser. The engagement occurred during the second Austrian attempt to raise the siege of Mantua. It was a French victory; however, it was the last battle in Napoleon's perfect military career as two months later he would be defeated at the Second Battle of Bassano, ending his victorious streak. The Austrians abandoned their artillery and baggage, losing supplies, cannons, and battle standards to the French. The victory led to Wurmser being trapped in Mantua, but Napoleon would find his army now badly overstretched, due to holding both Trento and Bassano, meaning he could not support either of those locations without being drawn too far away from the other, something that would nearly allow the Austrians to win during the third attempt to raise the siege of Mantua in November.
