D-Day is underway, but at Omaha Beach, 'the Bedford Boys', volunteers of the US 29th Infantry Division, find themselves thrown into freezing surf and a murderous German cross-fire. As the first assault waves are mown down on the ramps of their landing craft, it looks like the Allied invasion of Europe might be careering towards disaster. But at other beaches the British, Canadian and US troops are soon able to advance inland. For the local French population it is a moment of joy, but also great danger. Hundreds are killed when the RAF bombs the Norman town of Caen – one of their D-Day objectives. The fighting inland is no less fierce than on the beaches. As 'the Longest Day' draws to a close, rumours circulate on both sides that the enemy is shooting its prisoners.
