Some links about this battle:

All the above gives a number of German "losses" going from Allied sources, that is probably inflated.
IIRC the Ju 88 fighters of KG 40/ZG 1 were at the time escorting this kind of raid over the Medditerranean, and there may be something in the book 'Bloody Biscay', but I don't have it at hand today.
