A Great War Pair and Plaque awarded to Private John Edward Warren, 4th Canadian Mounted Rifles (Central Ontario Regiment), who was killed in action on 2 June 1916 during the Battle of Mount Sorrel – where 4 huge German mines were exploded beneath their position in addition to an artillery barrage, and only 76 of the 402 men of the 4th C.M.R. avoided being taken casualty, comprising: British War & Victory Medals (113621 Pte. J. Warren. C.M.R.); Memorial Plaque (John Warren); Group loose, uneven tone, extremely fine (3). Private John Warren was born 27 April 1893 in Poplar, London, and had worked as a Farmer in early life. He enlisted for Great War service at Ottawa, Ontario, on 29 July 1915, and served initially with the 8th Battalion C.M.R., before joining the 4th Battalion Canadian Mounted Rifles on 29 January 1916 for service in France and Flanders. He was present during the Battle of Mount Sorrel, and after initially being reported missing, he was confirmed as being killed in action on 2 June 1916. An online source records that: 'On the morning of June 2, 1916 a furious bombardment was unleashed against the Canadian positions, and simultaneously four huge mines were exploded under Mount Sorrel. Trenches and their defenders vanished, and those who survived offered virtually no resistance to the German infantry as they attacked. Of 702 men in the 4th Canadian Mounted Rifles, only 76 survived unwounded.' He is remembered on the Menin Gate Memorial, Ypres.
