More than 300 veterans are sailing back to the beaches of Normandy to mark the 75th Anniversary of D-Day.

The pivotal battle began on June 6, 1944, on the shores of northwestern France, where about 14,000 Canadian soldiers joined British and American troops to smash through Nazi forces.

CTV’s Todd Battis is travelling with the veterans aboard the cruise ship MV Boudicca to share their stories.

The trip, which is being organized by the British Royal Legoin, will take the group to D-Day events in England and France -- including the commemorative ceremony in Portsmouth, U.K., where the Queen will be joined by U.S. President Donald Trump. On Thursday, MV Boudicca will dock at Normandy for a memorial service at Bayeux Cathedral.

Many of the veterans aboard the ship are now in their 90s, some over the age of 100. Legion spokesperson Nicole Cook acknowledged this could be the last chance some have to return to Normandy.

"It's about recognizing people's sacrifice, recognizing the commitment and losses that all of the forces internationally suffered,” she said.
