task of evaluating the then new Dornier Do 335, a twin-engine heavy fighter with a unique "push-pull" layout, for its suitability as night fighter. Disobeying his ban from combat flying, he flew his last mission of the war on 9 April 1945. Attempting to chase a Lancaster, he took off from Faßberg Air Base at 22:00 and landed after 79 minutes at 23:19 without success. Prisoner of war Schnaufer was taken prisoner of war by the British Army in Schleswig-Holstein in May 1945. According to Schumann, he was taken to England for interrogation. In this account British authorities were especially interested in knowing whether his achievements had been made under the influence of methamphetamine or other stimulating psychoactive drugs which induce temporary improvements in either mental or physical functions or both, as had been documented in widespread Wehrmacht use and made for the German military by the Temmler-Werke GmbH firm, under the name Pervitin.

The German prisoners were brought to Eggebek. Here they conducted a number of interviews with various members of the night fighter force. Later life and death Following his release from the hospital and as a prisoner of war—the exact date is unknown—Schnaufer took over the family wine business. He had never planned to run the family winery as his ambition had always been to pursue an officer's career in the Luftwaffe. However, in the immediate aftermath of World War II the business had virtually ceased to exist and Schnaufer was given the task of rebuilding it from scratch. He had to re-establish business links to suppliers and customers and to consolidate them. Then he had to make new contacts in order to facilitate expansion and growth of the business. Lastly, he had to create an infrastructure which supported the growth of the business. As the wine business began to prosper, Schnaufer also gave thought
