In the spring of 1940, the Germans invaded France, and the British army crossed the English Channel to fight alongside its ally. But the blitzkrieg quickly punched through French defenses and threatened to cut off and trap the British in France—until the British managed to escape at Dunkirk. The dashing Henry de la Falaise, a French marquis, World War I hero, and Hollywood director, served in a British armored car regiment, with which he fought in the Battle of France, the retreat to the Channel, and the miraculous evacuation from Dunkirk. This is his story: a dramatic firsthand account of one of the pivotal moments of World War II.
