Pls, help identify Jagdwaffe units involved

[Lagarto]

Recently I've been researching the subject of the Curtiss P-40's service in MTO. They were involved in several big clashes with the Luftwaffe. Could anyone help identify which German fighter units were involved in each case and possibly verify the number of credited victories?

18th April 1943 over Cap Bon, Tunisia, the famous "Palm Sunday Massacre" - several 109s were claimed downed, also six P-40s and one Spitfire lost

10th June 1943, over Pantelleria - apparently Warhawks twice bounced 109s escorting rescue flying boats; P-40 pilots were credited with 21 victories.

30th July 1943 over Sardinia - 325th FG's Warhawks were credited with destruction of as many as 21 Messerchmitts 109, for the loss of only one of their own.

Thank you in advance
