The 33rd Division was an infantry division of the British Army that was raised in 1914, during the First World War. The division was raised from volunteers for Lord Kitchener's New Armies, that was originally made up of infantry battalions raised by public subscription or private patronage. The division was taken over by the War Office in September 1915. It served in France and Belgium in the trenches of the Western Front for the duration of the war. The division's insignia was the "double-three" from a set of dominoes.
