The Helles Memorial serves the dual function of Commonwealth battle memorial for the whole Gallipoli campaign and place of commemoration for many of those Commonwealth servicemen who died there and have no known grave.
The United Kingdom and Indian forces named on the memorial died in operations throughout the peninsula, the Australians at Helles. There are also panels for those who died or were buried at sea in Gallipoli waters.
There are four other Memorials to the Missing at Gallipoli. The Lone Pine, Hill 60, and Chunuk Bair Memorials commemorate Australian and New Zealanders at Anzac. The Twelve Tree Copse Memorial commemorates the New Zealanders at Helles. Naval casualties of the United Kingdom lost or buried at sea are recorded on their respective Memorials at Portsmouth, Plymouth and Chatham, in the United Kingdom.
There are 20956 names commemorated on the Memorial
