Summary of career
Aerial victory claims
Matthews and Foreman, authors of Luftwaffe Aces — Biographies and Victory Claims, researched the German Federal Archives and found records for 181 aerial victory claims, plus five further unconfirmed claims. This figure includes 162 aerial victories on the Eastern Front and 19 over the Western Allies. Victory claims were logged to a map-reference, for example "PQ 39362". The Luftwaffe grid map 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. These sectors were then subdivided into 36 smaller units to give a location area 3 × 4 km in size.
