Strange Victory by Steven Cunliffe is a solitaire design that that illustrates how just a few crack German panzer divisions in the battle for France in 1940 paralyzed the Allied decision cycle to produce a catastrophic failure on the Allied side. Amusingly, the attack was so successful it panicked the German High Command as well!
This was also the operation that gave birth to the idea that Blitzkrieg idea of warfare was simply unstoppable (which the Germans found to be completely untrue the following year in Russia).
Players will have no difficulty cutting through Allied lines in this game. But the better the German player does may well panic his own High Command into ordering a halt! Possibly leading to “The Miracle of Dunkirk.”
