Midnight had not long struck when the British and American airborne armada began its mission in the moonlight on 6 June 1944. They landed at the edges of the five invasion areas on the Normandy coast to secure the western and eastern flanks of the beachheads and protect them from German attacks. Failure would have given Hitler the opportunity to initiate an eleventh-hour attempt to save Germany and launch his new V-weapons against British cities. Success meant the beginning of the end of WW2 and one of the most important days in recent history. We meet an army doctor who will describe what happened, the problems he faced as part of the invasion, and the medical equipment he had to treat the wounded.
