 Reginald <unk> 's <unk> Gate was the first memorial to the missing located in Europe to be completed , and was unveiled on 24 July 1927 . The <unk> Gate ( <unk> ) was found to have insufficient space to contain all the names as originally planned and 34 @,@ <unk> names of the missing were instead inscribed on Herbert Baker 's <unk> <unk> Memorial to the Missing . Other memorials followed : the Helles Memorial in Gallipoli designed by John James <unk> ; the <unk> Memorial on the Somme and the <unk> Memorial designed by Edwin <unk> ; and the Basra Memorial in Iraq designed by Edward <unk> Warren .
