Prince William will travel to France with Prince Charles and Prince Harry next month to mark the 100th anniversary of the Battle of Vimy Ridge.
The 34-year-old royal is set to join his younger brother Harry and their father Charles at the commemorations being held at the Canadian National Vimy Memorial on the site of the battle near Lille in Northern France, on April 9.
The Battle of Vimy Ridge took place over four days in 1917 during the First World War, and resulted in around 3,500 Canadian soldiers losing their lives, whilst another 10,000 were left wounded. The battle is regarded as Canada's most notable military victory and a symbol of the birth of the country's national pride.
Canada's victory at Vimy Ridge marked the start of a vital strategic breakthrough for the allied forces, as British and French soldiers had previously failed to take control of the ridge from German forces who seized control in 1914.
French soldiers attempted an attack on the ridge in 1915, but failed after suffering a staggering 150,000 casualties.
Prince Charles, 68, will attend the ceremony with his two sons on behalf of his mother Queen Elizabeth, who is also the Queen of Canada.
She last visited the site in 2007 for the 90th anniversary of the battle, where she praised the "courage and achievement" of the Canadian soldiers for their "stunning victory" over German forces.
Meanwhile, Prince William's attendance at the event will come as he recently snubbed celebrations of Commonwealth Day (13.03.17) in favour of a skiing holiday with his friends in Verbier, Switzerland.
Queen Elizabeth held the ceremony at Buckingham Palace, which was also attended by Prince Harry, 32, Prince Charles, Prince Philip, Duchess Camilla, Prince Andrew, and Prince Edward.
