The Great War documents the first world wide conflict; from the assassination of Archduke Franz Ferdinand to the Armistice on 11th November, 1918. In between, millions perished at Ypres, Verdun, the Somme and globally. It saw the introduction of the tank, the airplane, submarine warfare and the use of poison gas; and on the home front the Women's Army Auxiliary Corps and the first raids. Mutiny in Russia's ranks forced her withdrawal from the conflict. However, morale was restored by a strinc of Allied successes. Spectacular gains were achieved by Canadian forces at Vimy Ridge and the Battle of Messines allowed for the much larger third Battle of Ypres. In November, the Battle of Cambrai heralded the first time tanks were used with marked success.
