Britain, France, and Belgium, 1939-1940 (Waterlow Publications)

The remarkable series of events that led to the campaign of May 1940 tended to be overshadowed, for the British, by the dramatic aftermath of Dunkirk; the Battle of Britain, the U-Boat War, and the operations in North Africa. Nevertheless, these events exerted a decisive influence on allied strategy and policy for the remainder of the war.
