I've recently purchased Osprey's "Dunkirk 1940" and I am beginning to think this would be a possible campaign theme. Beginning on May 22 it would encompass Guderian's advance on Boulogne and Calais, the investment of said towns (with plenty of mission potential) and of course the actual attacks on the Dunkirk perimeter (anti-shipping ops, anti-artillery ops, attacks on german supply lines by Blenheims, fighter escort and sweeps etc). Problem is the german planeset would be limited to the Bf 109 E-1, E-3, Bf 110 C-4 and the Ju 87 - no fighter-bombers whatsoever and all tactical bombers would have airstarts. Would that be feasible?

There is no where for the Germans to realistically take off from. I think it might make a good Red single player campaign but apart from that, the map just lets it down.

Not really. The airfields in the area of Baupaume and Arras would be useful ... exact historical accuracy is not achievable anyway.
