Charles William Ferdinand was part of the allied Anglo-German force at the Battle of Minden (1759), and the Battle of Warburg (1760). Both were decisive victories over the French, during which he proved himself an excellent subordinate commander. He continued to serve in the army commanded by his uncle for the remainder of the war, which was generally successful for the north German forces. The hereditary prince's reputation improved throughout, and he became an acknowledged master of irregular warfare. Peace was restored in 1763.
