 After eight months of bloody fighting it was decided to evacuate the entire force on the Gallipoli peninsula . Troop numbers were progressively reduced from 7 December and cunning ruses were performed to fool the Turks and to prevent them from discovering the Allies that were departing . At Anzac , the troops would maintain utter silence for an hour or more until the curious Turks would venture out to inspect the trenches , whereupon the Anzacs would open fire . As the numbers in the trenches were thinned , rifles were rigged to fire by water dripped into a pan attached to the trigger . In what was ironically the best planned operation of the campaign , the evacuation was completed by dawn on 20 December 1915 , without a single casualty .
