The Phoney War was an eight-month period at the start of World War II, during which there were no major military land operations on the Western Front. It began with the declaration of war by the western Allies (the United Kingdom and France) against Nazi Germany on 3 September 1939, following the German invasion of Poland, and ended with the German attack on France and the Low Countries on 10 May 1940.
