Napoleon's capture of Milan on 2 June found the Austrian army separated into three major and several minor concentrations. General Michael Melas held Turin with 18,000 men, Feldmarschall-Leutnant (FML) Peter Ott's 16,000 troops remained near Genoa where they secured the surrender of General of Division André Masséna's starving garrison on 4 June, and FML Anton von Elsnitz with 8,000 soldiers retreated from the Riviera. To the east of Milan, FML Josef Philipp Vukassovich had 4,000 men. South of the Po River, FML Andreas O'Reilly von Ballinlough marched east toward Piacenza with 3,000 men. Strong garrisons manned the fortresses of Alessandria, Coni and Casale. Melas believed he had plenty of time to mass his army and launch a counter-offensive north from Piacenza.
