The 25th of April, 1915 marked the beginning of the "Gallipoli Campaign" - a military invasion of Ottoman Turkey with ground forces predominately from Australia and New Zealand. The combined force from these two countries was officially called the "Australian and New Zealand Army Corps", or "ANZAC" for short. The campaign was a complete failure, and the ground troops were ultimately unable to capture the Gallipoli peninsula, let alone proceed to invade Constantinople. By November of 1915 the British command had abandoned the plan and begun evacuations.
