Summer, 1940, update:
Operation Sea Lion, the Nazi amphibious invasion of southern England, stalls in front of the GHQ line. The Royal Navy regains control of the English Channel, starving the invaders of supplies and reinforcements, and the British armoured divisions commence a thunderous run to the sea.
The German situation is desperate but not hopeless. Hitler has one last card to play - a mechanized invasion of northern England by air. Ride with the DEK down the Great North Road to London or join O'Connor Force and hit back, with new units, rules and scenario ideas.
