WATCH: Forces News has been meeting veterans in Yorkshire as they reflect on that famous day in 1944.
On the 74th anniversary of the D-Day landings, veterans are being asked to register for events planned for next year's commemorations.
The Normandy Landings, commonly referred to as D-Day, began on June 6 in 1944 when allied forces launched a combined naval, air and land assault on Nazi-occupied Europe.
The Government, the Royal British Legion and organisations including the Commonwealth War Graves Commission, the Normandy Memorial Trust and the Spirit of Normandy Trust are planning commemorations to mark D-Day 75, both in France and across the UK.
They want as many veterans as possible to make the trip and they're calling on the public to spread the message.
Veterans too poorly to travel to Normandy for this year's event have attended a service at the National Memorial Arboretum:
Defence Secretary Gavin Williamson said: "The Normandy Landings were the vital springboard to the liberation of Europe and the end of the Second World War.
"The breath-taking bravery and ingenuity shown during those days still echo through today's armed forces.
"At D-Day 75 the eyes of the world will be on these men once more. To enable us to do them justice it's important we find as many veterans as possible and let them know how to participate.
"We will never forget the debt we owe for the peace and freedom we now enjoy on this continent."
Memorial services are set to take place in Normandy, the south coast of England, the National Memorial Arboretum, Scotland, Wales and Northern Ireland.
The Royal British Legion says veterans and their families that register on the D-Day 75 website will be kept updated as plans are confirmed and more details are released.
