The Gallipoli Campaign, also known as the Dardanelles Campaign or the Battle of Gallipoli or the Battle of Canakkale, took place on the Gallipoli peninsula in the Ottoman Empire (now Gelibolu in modern day Turkey) between 25 April 1915 and 9 January 1916, during the First World War. A joint British and French operation was mounted to capture the Ottoman capital of Constantinople (Istanbul) and secure a sea route to Russia. The attempt failed, with heavy casualties on both sides. The campaign was considered one of the greatest victories of the Turks and was reflected on as a major failure by the Allies.
