The unusual squat columnar memorial was designed by Sir Mark Sykes, 6th Baronet and built in 1919–20.
Most were sent to serve on the Western Front in France, with little or no military training, and given the important logistical task of moving essential materiel: food, ammunition and equipment.
Sykes attended the 1919 Paris Peace Conference, but contracted Spanish flu and died in February 1919, before the memorial was completed.
The masonry was built by Alfred Barr and the naive art sculptures made by Carlo Domenico Magnoni, curving around a central column in three sections, similar to Trajan's Column, showing scenes from the history of the Wagoners, from Sykes enlisting them, through them being called up, travelling to France, and graphic scenes of conflict.
The memorial was unveiled on 5 September 1920 by Sir Ivor Maxse, General Officer Commanding-in-Chief Northern Command.
