The battalion proceeded to Egypt, arriving on 2 December and after a period of training it took part in the Landing at Anzac Cove on 25 April 1915, where it went ashore as part of the second wave. Shortly after the landing the 2nd Brigade was transferred from Anzac Cove to Cape Helles to assist in the attack on Krithia. During the unsuccessful attack, the 6th Battalion suffered heavy casualties, losing 133 men killed or died of wounds. Afterwards, they returned to Anzac Cove, arriving there on 17 May, to take part in defending the beachhead that had been established. In August, when the Allies attempted a break out, the battalion took part in the attack on Lone Pine. In September they were withdrawn for a period of rest to Lemnos. They returned in November and resumed defensive duties. By that time, due to the failure of August Offensive, the campaign evolved into a stalemate. They remained in the line December, when the Allies carried out a successful evacuation. During the campaign they lost 22 officers and 398 other ranks killed.
