By February 1915, the North America and West Indies Squadron consisted of "Glory", six cruisers, and one armed merchant cruiser. "Glory" transferred to the Mediterranean in May 1915 to participate in Dardanelles campaign, arriving at the Dardanelles in June 1915. This was after the British and French fleets had made their attempts to force the straits in February, March, and April; by the time "Glory" arrived, the ground forces had gone ashore. As a result, the ship saw comparatively little activity. This was in large part due to the fact that "Glory" was selected to send a large portion of her crew ashore to assist with the landing and distribution of weapons and stores. Since she did not have a full crew, she could not support the Landing at Suvla Bay in August. Indeed, "Glory" had not fired her guns at all until early October, when she joined the battleship to shell Ottoman positions at Gallipoli. At the end of 1915 she left the Dardanelles and joined the Suez Canal Patrol in the Mediterranean on 4 January 1916. In April 1916, she returned to the United Kingdom and began a refit at Portsmouth that lasted until July 1916.
