 In early 1915, however, it was decided to carry out an amphibious landing on the Gallipoli peninsula with the goal of opening up a second front and securing the passage of the Dardanelles.The Australians and New Zealanders, grouped together as the Australian and New Zealand Army Corps (ANZAC), went ashore on 25 April 1915 and for the next eight months the Anzacs, alongside their British, French and other allies, fought a costly and ultimately unsuccessful campaign against the Turks.The force was evacuated from the peninsula in December 1915 and returned to Egypt, where the AIF was expanded.
