Jochen, I think you misread Foreman's book. 331 Sqn had only one loss (Spitfire IX BS144 hit and returned to base one fire, CAt C then B, Lt. Svein Heglund safe) while the Germans claimed 3 kills. The claim/loss table for the day shows only one loss (Cat E) for the squadron.
Situation is complicated by the fact that St Omer and Ghent were raided at the same time. From German claims it seems to me that JG 26 opposed the St Omer raid while JG 1 intercepted the Holland raid. But it may be not so simple.
According to Tony Wood (to quote him: "These lists
are my interpretations of "Allied Combats & Casualties" which were taken from the official RAF Fighter Command records held at PRO/Kew. The Lists or Tables give every Mission flown by Fighter Command, and later USAAF Fighter Command, from the end of the Battle of Britain [1.11.40] to the eve of the Invasion of Normandy [5.6.44] at present"), the RAF side of the show was following:
