Although World War 2 began in September 1939, when Great Britain and France declared war on Germany after the invasion of Poland, eight uneventful months of ‘Phoney War’ followed, as the Axis powers and the Allies readied themselves for another confrontation in north-west Europe. The battlefront would be much more fluid than in World War 1, with faster-moving tanks on the ground and more destructive fighters and bombers in the air. The similarity was that, Poland aside, both conflicts began with a German attack on Belgium.
