Bonaparte saw the Siege of Mantua to a successful conclusion when Dagobert Sigmund von Wurmser surrendered on 2 February 1797. The French commander cleared his south flank by Claude Perrin Victor's victory over the Papal States at the Battle of Faenza the following day. Meanwhile, Emperor Francis II of Austria recalled Archduke Charles from Germany to hold northeast Italy. In March Bonaparte launched an offensive designed to break through the Austrian army's defenses. At Valvasone, the French encountered part of their opponents' army and drove it back. For the loss of 500 men, the French inflicted 700 casualties on the Austrians and captured six guns.
