This dynamic campaign for 4.09m+UP2.01 tries to model typical fighter sweeps performed by No.41 and No.91 Squadron across the English Channel, over German occupied France.
Both units were based at Westhampnett during July 1943, when action takes place, flying early Spitfire Mk.XII.
Normandy map used in game fakes it by "British base" on island off French coast.
I tried to get historical order of battle for all units involved.
