There is a list of French claims in the late Christian-Jacques Ehrengardt's « À la Reconquête de la France (01.43–08.44) » in Aéro Journal No. 23 (February–March 2002). This gives the claimants for the He 111 on 18 June (Gouachon, Ducru, Gauthier and Bernard) but says nothing about any Bf 109s. Obviously, I don't know what sources he was using.

There are no corresponding Bf 109 losses for 18 June in Jean-Bernard Frappé « La Luftwaffe Face au Débarquement Allié » either.
