Back in 2014, the 70th anniversary of the D-Day invasion of France, Jean-Christophe Rosé produced this 90-minute documentary for France Télévisions. It uses archival footage that was remastered and colorized, and is probably one of the best sources to understand what the run-up to D-Day involved (with training and other preparations) and the reality of combat on that day.I'll also mention my father, who was not part of D-Day itself, but served in the Royal Air Force throughout World War II, and shouldered his share of the burden.Finally, may all those who died on D-Day, on all sides, rest in peace. There's no enmity beyond the grave.(Oh - and for those wondering about the headline: the D-Day invasion, known at the time as Operation Neptune, was the largest in history so far, in terms of numbers of people [on land, at sea and in the air], numbers of ships and aircraft, etc. The largest invasions of the Pacific War were Operation Musketeer (the invasion of the Philippines), Operation Detachment (the invasion of Iwo Jima) and Operation Iceberg (the invasion of Okinawa), but none of them were as large as Operation Neptune in Normandy. The planned invasion of Japan in Operations Olympic and Coronet would have been larger, by a significant degree, but those invasions never took place, thanks to the dropping of atomic bombs on Hiroshima and Nagasaki.)Peter
