28th JUNE 1944 - Luftwaffe attack on ALG B7 Martragny
 

Hi all,
according to RAF records – 6 or 8 Fw190´s attacked at „lunch time“ British Advanced Landing Ground B7 in Martragny. Two of them were shot down by allied AA.
Can anybody helps with identification of Luftwaffe unit which attacked Martragny ALG and confirmation of loss of 2 Fw190´s during the attack.
TIA
Munro
