There were no FW 190 fighters operating over Anzio in the first month, only S.G. 4 fighter-bombers.
As for Bf 110s over the Bay of Biscay, on 8 October 1943 there were three engagements between II./Z.G. 1 and Allied fighters. Spitfires were sent out on dedicated anti-Bf 110 patrols, and eight Bf 110s were shot down, with two others landing with damage. In return, the RAF lost two Spitfires destroyed and one damaged. II./Z.G. 1 left France for Austria in October/November 1943.
