Paul,

the I./JG 4 could be left aside, because they were in combat with a P-38 formation some 50 to 70km southeast of Prüm.

Over the area around Prüm, the so called "Schnee Eifel" III. and IV./JG 4 lost together 10 Bf 109 during that dogfight. The losses listed in post #2 are only those, where the pilot was effected.
