The D Day landings at Normandy

There being so much on the MSM plus the net, this will be a commemoration but the fine detail can be found in most western publications. For those born on the Planet Zog:

The Normandy landings were the landing operations and associated airborne operations on 6 June 1944 of the Allied invasion of Normandy in Operation Overlord during the Second World War. Codenamed Operation Neptune and often referred to as D-Day (after the military term), it is the largest seaborne invasion in history. The operation began the liberation of France, and the rest of Western Europe, and laid the foundations of the Allied victory on the Western Front.

Naturally we commemorate the planning, decoys, assembly and operation … especially the bravery of those participating … most westerners, plus others have at least some family connection with the event.
