The regiment left their horses in Egypt, and arrived at the Gallipoli peninsula on 12 May, joining the Allied forces there as reinforcements. Assigned to the New Zealand and Australian Division, the regiment fought around Anzac Cove, and during the Battle of Sari Bair, but spent most of the campaign in a defensive posture except for one attack they made on the Turkish position at "Quinn's Post" in mid-May, where they lost 25 men killed and 21 wounded before the assault was called off. The regiment left Gallipoli for Mudros, on the island of Lemnos, on 18 December 1915 as part of the Allied evacuation of the peninsula. For their involvement in the campaign, the regiment earned four battle honours.
