Prior to being shot down, Ewald claimed a B-24 bomber. He made two attacks on the bomber. The first, head on, attack, damaged the bomber and separated it from its combat box. The second attack, which flown from the stern, was observed to have shot down the B-24 bomber with its left wing on fire. Flying a third attack on the bomber formation, Ewald was hit by the defensive fire of another bomber. His engine caught fire and he was forced to bail out. Fearing to be shot in his parachute by an escorting fighter, he let himself fall to approximately before opening his parachute. On 30 September, II. Gruppe moved to Nagyrábé. Here on 6 October, Ewald claimed his first aerial victory following his injuries sustained on 24 June when he shot down a Yakovlev Yak-11 aircraft. He received the German Cross in Gold () on 30 November.

Gruppe moved to Veszprém where they stayed until 21 March. Here the Gruppe supported the 6th Army fighting in Operation Konrad III to relieve the siege of Budapest. Ewald claimed an aerial victory over an Ilyushin Il-2 ground-attack aircraft the next day, a Douglas A-20 Havoc bomber, also named "Boston", on 20 January. On 22 January, he was credited with four La-5 fighters shot down near Stuhlweißenburg, now Székesfehérvár, followed by another La-5 on 30 January. Credited with 67 aerial victories, he was the third most successful active fighter pilot in II. Gruppe.

Summary of career

Aerial victory claims According to US historian David T. Zabecki, Ewald was credited with 84 aerial victories. Spick also lists Ewald with 84 aerial victories claimed in 396 combat missions and a mission-to-claim ratio of 4.71. Mathews and Foreman, authors of Luftwaffe Aces — Biographies and Victory Claims, researched the German Federal Archives and found records for 82 aerial victory claims, including one P-51 fighter, plus 16 further unconfirmed claims. All of his confirmed victories were claimed on the Eastern Front.

Victory claims were logged to a map-reference (PQ = Planquadrat), for example "PQ 34 Ost 66562". 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 in size.
