In the spring of 1759, when Dohna went to Berlin to recuperate from illness, Manteuffel assumed Dohna's command. In the middle of May, Manteuffel led the greater part of the troops to Stargard against the Russians. Here Dohna, now advised by Moritz Franz Kasimir von Wobersnow, resumed command briefly. Manteuffel fought at the Battle of Kay on 23 April 1759, and was wounded there while trying to break the Russian right flank; later, in Berlin, he was ordered to form a corps with which he was to expel the Swedes from the Prussian territory. In January 1760 he attempted to push the enemy back, he was attacked and wounded on the 28th of that month in the early morning hours at Anklam, while he and his troops engaged in hand-to-hand combat with the Swedes. An armistice of Ribnitz, concluded on 7 April 1762, ended the Pomeranian War. His injuries, though, proved sufficient to retire. He went to his estate Collatz in the district of Belgard in Hinterpommern, where he died on 10 July 1778.
