British and Allied forces are pushed back by an overwhelming German Army. 400,000 Allied troops are trapped in the French town of Dunkirk. After several failed attempts at rescue, the British Navy was able to rescue 330,000 troops.
Early in the war, the Germans decide they need to guarantee access to the Norwegian port of Narvik to ensure their supplies of Swedish iron ore. The British, however, send destroyers to up-end the German plan.
