Royal Newfoundland Regiment
During the First World War the battalion-sized Newfoundland 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 1 July 1916, the first day of the Battle of the Somme, but was rebuilt and continued to serve throughout France and Belgium until the armistice, then serving as part of the British Army of the Rhine in 1919. In December 1917, George V bestowed the regiment with the right to use the prefix "Royal" before its name. It was the only military unit to receive this honour during the First World War.
