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. 1915 was characterised by deadlock and a widening of the conflict. British cities were bombed by Zeppelin airships, German U-Boats attacking neutral shipping and gas was used at the Battles of Bolimov, Ypres and Loos. The Italians faced awful hardships in the first of twelve battles along the Isonzo River and the year ended with the Allies' withdrawal from Gallipoli.
