Gallipoli - 28 April 1915
Marines were involved in both the initial, unopposed, landings on the peninsula and the subsequent amphibious operation to relieve troops once the Turks reinforced the position. Marines bore the brunt of Turkish attacks around Anzac Cove, where they had relieved the Australians. The Turks were also driven back a substantial distsance by a counter attack by marines in another part of the peninsula.
A Victoria Cross was also awarded to a Royal Marine during this campaign (Lance Corporal Parker, for evacuating wounded under fire).
