This interactive diagram shows the number of fatal and non-fatal casualties for Allied and Ottoman forces during the Gallipoli campaign (April 1915–January 1916).
The Gallipoli campaign was a costly failure for the Allies, with an estimated 27,000 French, and 115,000 British and dominion troops (Great Britain and Ireland, Australia, New Zealand, India, and Newfoundland) killed or wounded. Over half these casualties (73,485) were British and Irish troops. New Zealand suffered around 8000 killed and wounded, about 5.6 percent of Allied casualties on Gallipoli. The Ottoman Empire paid a heavy price for their victory: an estimated 250,000 Turkish and Arab troops were killed or wounded defending Gallipoli.
Note: It is difficult to determine exact casualty figures for the Gallipoli campaign as numbers vary in different publications. The statistics used for this graphic are based on casualty figures in Richard Stowers, Bloody Gallipoli (2005).
