I've seen plenty of BoB setups, but never a Dunkirk setup. If you took the map Jester did recently and altered it to reflect 4 or 5 ports on the French coast and placed the allied bases in England and the German bases in Belgium, Holland and Germany equidistant from the ports it would be historically representative of the era.
The idea is for the axis to try and capture the ports preventing allied escape. Plane Set:
Allies
Hurri I
Spit I
M3
M16
M8
Axis
Bf109E4
Bf110C4(restricted to rear fields)
Ju87
M3
Panzer IV
This might work better as a scenario, but I wouldn't mind given it a try in the CT even though I'm a PAC fan.
