Today we are commemorating the 80th anniversary of D-Day – ‘Operation OVERLORD’ – with fitting ceremony and reverence, though, some polls suggest, without much understanding. Some confusion in the public mind about the precise meaning and importance of the Normandy landings is surely understandable. D-Day itself, 6 June, however vital, was the culmination of a long process, and the beginning, not the end, of a bloody and grinding struggle.
