Hi
What date is this related to? Page 422 of previous source has Lt Waldemar Soffing of JG 26 claiming a Spitfire XIV on 14 Feb. 1945 for his 24th victory, however, the RAF did not lose any in the engagement concerned. Also page 518 has Soffing of 2.Staffel claiming a 'Griffon' Spitfire on 29 April, 1945 at 1253 hrs, only Merlin Spitfires were involved. However, at that time Fw Helmut Walter of 1 Staffel was shot down and killed (it appears to be a hint that there was a friendly fire incident?), two other German pilots were also shot down and killed.
