At the age of 20 he graduated from one of the Luftwaffe's fighter pilot schools just in time to participate in the Battle of Britain, without notable success. A charming person, he had such a busy night life that sometimes he was too tired to be allowed to fly the next morning. As a result of poor discipline, he was transferred to Jagdgeschwader 27 (Fighter Wing 27, JG 27), which relocated to North Africa in April 1941.
