This blog answers the question, “Why was D Day significant ?” It also deals with several questions including what happened on that day. It highlights artefacts and displays in various museums in France and the D Day Story in Portsmouth. By 1944, all across Europe, people’s former freedoms were now denied them and Jews were rounded up to be executed in the “Holocaust”. The Nazis needed to be removed from all occupied areas and freedom restored. D Day in June 1944 was one of the events that turned the tide on German expansion. Invading France was no easy operation. In 1942, the British and Canadians had attempted an invasion of Dieppe which resulted in an embarrassing disaster. Far resources of all kinds were needed for a successful invasion. The coastal defences would have to be bombarded from the air and sea with a vast array of planes and ships. More planes would be needed to guarantee air superiority to allow troops to be landed unhindered. Numerous vehicles and contraptions would have to be invented and manufactured to clear away all of the beach devices to allow the men to land and have a clear way to getting ashore.
