During one of the practice flights Gratz was nearly shot down by his wingman "Leutnant" Dietrich Schultz-Sembten. Schultz-Sembten had mistakenly fired all of his rockets prematurely during the attack run. After the landing, Gratz is quoted with having said: "Schultz-Sembten, you must have gone mad! I have to say one  thing, you idiot: If you had hit me, I would have outmaneuvered you and shot you down." Summary of career. Aerial victory claims. According to US historian David T. Zabecki, Gratz was credited with 138 aerial victories. Obermaier and Spick also list Gratz with 138 aerial victories, including 17 on the Western Front of which three of them were USAAF four-engined bombers. Barbas states that Gratz claimed 18 aerial victories after 16 February, 14 of which are undocumented. Matthews and Foreman, authors of "Luftwaffe Aces — Biographies and Victory Claims", researched the German Federal Archives and state that Gratz was  credited with 138 aerial victories. This figure includes 132 aerial victories on the Eastern Front and six over the Western Allies, including one four-engined bomber. Victory claims were logged to a map-reference (PQ = "Planquadrat"), for example "PQ 44442". 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.
