The landing at Cape Helles was part of the Gallipoli Campaign, the amphibious landings on the Gallipoli peninsula by British and French forces on 25 April 1915 during the First World War. Helles, at the foot of the peninsula, was the main landing area. With gunfire support from the Royal Navy, the 29th Division was to advance six mi (9.7 km) along the peninsula on the first day and seize the heights of Achi Baba. The British then planned to capture the forts that guarded the straits of the Dardanelles.

The Hampshire Regiment was a line infantry regiment of the British Army, created as part of the Childers Reforms in 1881 by the amalgamation of the 37th Regiment of Foot and the 67th Regiment of Foot. The regiment existed continuously for 111 years and served in the Second Boer War, World War I and World War II. An Army Order of the 28 November 1946 stated, due to distinguished service in the Second World War, the regiment would be re-titled as the Royal Hampshire Regiment.
