On 15 April 1799, the veteran Russian field marshal Alexander Suvorov formally took command of the combined Austro-Russian army in Italy. On 27 April Suvorov defeated the French, now under Jean Victor Marie Moreau, at the Battle of Cassano. The Allies suffered 2,000 casualties while the French sustained losses of 2,500 killed and wounded plus 5,000 soldiers, 27 guns and three colors captured. The next day a 3,000-man French division was trapped and surrendered at Verderio Superiore. The next major action was the Battle of Trebbia from 17 to 20 June where Suvorov's 37,000-strong Austro-Russian army mauled Jacques MacDonald's 33,000-man French army. The Allies suffered 5,500 casualties while inflicting 16,500 on the French including the taking of 7,000 prisoners. Meanwhile, Coalition forces successfully besieged a number of key fortresses. Peschiera fell on 6 May, Milan was captured on 24 May and Turin fell on 20 June after a nine-day siege. Suvorov and his Austrian allies had evicted the French from almost all of Italy, while Archduke Charles, Duke of Teschen beat André Masséna's French army at the First Battle of Zurich on 4–6 June.
