flak regiment at nantes
 

I look for the LUFTWAFFE flak regiment based at Nantes during WW2 used for the defence of Chateau-Bougon Airfield.
I know only that several flakship were based in the Nantes harbour and equiped with large calibre. Near the airfield several postswere installed ( one with 88mm at Rezé and several 37mm (?)on tanks on the airfield )
PLease can you help me ?
Many thanks
