On 11 November 1941, Zweigart made a forced landing at Sablin, near Lyuban, following combat damage sustained to his Messerschmitt Bf 109 F-2 (Werknummer 12943—factory number).[2]
On 27 July 1943, Zweigart was shot down in his Bf 109 G-6 (Werknummer 15678) by Supermarine Spitfire fighters, bailing out near Norden.[3]
According to US historian David T. Zabecki, Zweigart was credited with 69 aerial victories.[9] Spick also lists him with 69 aerial victories claimed in an unknown number of combat missions. This figure includes 54 aerial victories on the Eastern Front and 15 over the Western Allies.[1] Mathews and Foreman, authors of Luftwaffe Aces — Biographies and Victory Claims, researched the German Federal Archives and found records for 66 aerial victory claims plus two further unconfirmed claims. This figure includes 52 aerial victories on the Eastern Front and 14 on the Western Front, including ten four-engined bombers.[10]
Victory claims were logged to a map-reference (PQ = Planquadrat), for example "PQ 10131". The Luftwaffe grid map (Jägermeldenetz) covered all of Europe, western Russia and North Africa and was composed of rectangles measuring 15 minutes of latitude by 30 minutes of longitude, an area of about 360 square miles (930 km2). These sectors were then subdivided into 36 smaller units to give a location area 3 km × 4 km (1.9 mi × 2.5 mi) in size.[11]
