In early May, Bonaparte's French army won the battles of Fombio and Lodi and overran the Austrian province of Lombardy. Beaulieu evacuated Milan except for a 2,000-man garrison that he left in the citadel. In mid-May, the French occupied Milan and Brescia. At this time, the army had to pause to put down a revolt in Pavia. At the village of Binasco, the French atrociously massacred the adult male population. Beaulieu pulled his army back behind the Mincio, with strong patrols west of the river. He urgently tried to put the fortress of Mantua into a state where it could sustain a siege. This action compelled the Austrian army to retreat north up the Adige valley to Trento, leaving the fortress of Mantua to be besieged by the French.
