Frederick the Great's most notable and decisive military victories on the battlefield were the Battles of Hohenfriedberg, fought during the War of Austrian Succession in June 1745; the Battle of Rossbach, where Frederick defeated a combined Franco-Austrian army of 41,000 with only 21,000 soldiers (10,000 dead for the Franco-Austrian side with only 550 casualties for Prussia); and the Battle of Leuthen, a follow-up victory to Rossbach in which Frederick's 39,000 troops inflicted 22,000 casualties, including 12,000 prisoners, on Charles of Lorraine's Austrian force of 65,000.
