Battle of Dunkirk (may 26, 1940 – jun 4, 1940)
Description:
Battle of Dunkirk from May 26 to June 4, 1940A German invasion around the French coastal town of Dunkirk separates the French and British armies, marooning Allied forces. But with Adolf Hitler halting Germany's advance there, the Allies are able to perform a daring—and successful—evacuation, called Operation Dynamo. Germany claims victory with remaining Allied troops surrendering, but the evacuation serves to boost British morale, still referred to as the "Dunkirk spirit."
