Operation Overlord was the largest amphibious military operation ever launched, with a vast armada transporting over 150,000 Allied soldiers across the Channel. Just after dawn on 6 June 1944, the Allied troops assaulted the beaches of the Cotentin peninsula against stiff German resistance. Coordinated with the amphibious landings were a number of aerial assaults that carried out crucial missions to take key areas, enable the vital link up between the beaches. Casualties during the invasion were horrendous, but the assaults were successful. This book looks in detail at the plans and build-up to the operation, and discusses the events of D-Day in each of the key areas of the operation.
