Nevertheless, he was at the head of the regiment when it deployed on the left wing in the Battle of Leuthen. In the Battle of Hochkirch, he fought with the Cuirassier Regiment "Jung-Schönaich" No. 6 against the advancing Austrians. He was shot at the beginning of that battle in the shoulder. Despite the injury, he fought until he was forced off his horse. He was later found alive by his soldiers and taken to Bautzen. From there he went to Schweidnitz, where his wound became infected and killed him on 25 February 1759.
