Battle of Dunkirk
Dunkirk, and the evacuation associated with the troops trapped on Dunkirk, was called a "miracle" by Winston Churchill. As the Wehrmacht swept through western Europe in the spring of 1940, using Blitzkrieg, both the French and British armies could not stop the onslaught. For the people in western Europe, World War Two was about to start for real. The "Phoney War" was now over.
