On 9th January 1916, the Battle of Gallipoli concluded after over 8 months of fighting. Allied forces had launched full-scale amphibious assaults on the Gallipoli Peninsula in 1915 but were met with strong resistance and failed to make significant advances. With great losses on both sides and the evacuation of the Allies by early 1916, a campaign that might have ended the war two years earlier on Allied terms instead heralded victory for the Ottomans.
In the below photograph, taken just before the evacuation at Anzac, Australian troops can be seen charging near a Turkish trench; when they got there the Turks had already left.
If you're interested in finding out more about the Gallipoli campaign why not pre-order Dr Edward J. Erickson's new book, Gallipoli: Command Under Fire, available March 2015? Erickson's new history examines the campaign at the level of operational language, departing from emotive first-hand accounts to offer a broader perspective of the large scale military planning and maneuvering involved in the conflict.
