Tyne Cot UK missing lost in the Ypres Salient are commemorated at the Menin Gate memorial to the missing in Ypres and the Tyne Cot Memorial. Upon completion of the Menin Gate, builders discovered it was not large enough to contain all the names as originally planned. They selected an arbitrary cut-off date of 15 August 1917 and the names of the UK missing after this date were inscribed on the Tyne Cot memorial instead. Additionally, the New Zealand contingent of the Commonwealth War Graves Commission declined to have its missing soldiers names listed on the main memorials, choosing instead to have
Pozières Memorial and incorporating a Cross of Sacrifice. The names of the missing are inscribed on the panels, arranged by regiment or other unit. The fourth side of the cemetery, on the road frontage, is formed by an open arcade, with the entrance archway at its centre: the inscription is over this. The memorial was unveiled on 4 August 1930 by Sir Horace Smith-Dorrien, who had served as a general commanding the British II Corps and the British Second Army during the war. The memorial encloses a Commonwealth War Graves Commission cemetery, in which 2,758 Commonwealth servicemen are either buried or commemorated.
