On 2 August, Wurmser's 4,000-man advance guard under GM Anton Lipthay de Kisfalud drove General of Brigade (BG) Antoine Valette's brigade out of Castiglione. The next day, Augereau attacked Lipthay with 11,000 troops. In a bitter fight, the French forced Lipthay back to Solferino where he was reinforced by Davidovich. At length, Wurmser came up with his entire field army and stopped Augereau's drive. The Austrians suffered 1,000 casualties and GM Franz Nicoletti wounded. French losses may have exceeded 1,000 men, including BG Martial Beyrand killed. At the time, Wurmser and Quasdanovich's forces were about eight kilometers apart. On 3 August, the French inflicted crippling defeats on the Austrian Right Column in the Battle of Lonato. Quasdanovich finally ordered a retreat to the north. Sending Sauret to watch the withdrawing Right Column, Bonaparte now massed against Wurmser.
