Predecessor units trace their origins to 1795, and since 1949 Royal Newfoundland Regiment has been a unit of the Canadian Army. During the First World War the battalion-sized regiment was the only North American unit to fight in the Gallipoli campaign of 1915. Later in the war the regiment was virtually wiped out at Beaumont Hamel on July 1, 1916, the first day of the Battle of the Somme, but was rebuilt and continued to serve throughout France and Belgium until the armistice, serving as part of the British Army of the Rhine in 1919. Since 1916, July 1 has been marked as Memorial Day in Newfoundland and Labrador.
