Other He 111s lost in Southern France that summer were transport/liaison machines retained by KG 26 but I don't know about this particular one. II./KG 26 did report a single aircraft missing in action and III./KG 26 was missing two that day but these were probably Ju 88s taking part in the torpedo attack off Normandy
I didn't find any evidence of a Bf 109 being claimed (and regrettably the material losses file covering JGr. 200 has not yet been digitised by the bundesarchiv). From UK National Archives AIR 23/6510
