Major-General Malcolm Smith Mercer (17/9/1859-3/6/1916) was the highest ranking Canadian born officer to die in combat in either the First or Second World Wars. Compared to those generals who survived, and were able to write memoirs, very little has been written on Mercer. Two articles I came upon were:
“Malcolm Mercer“, from Wikipedia (not entirely sure who contributed to this article)
Gordon MacKinnon, “Major-General Malcolm Smith Mercer: The Highest Ranking Canadian Officer Killed in the Great War by Friendly Fire”, Canadian Military Journal, Spring 2007.
Mercer was born just outside of Toronto in 1859 in what then was Upper Canada. He attended the University of Toronto in 1881 and was called to the bar in 1885.(a) While at university he enrolled in the Queen’s Own Rifles as a private, and by 1911 he became Lieutenant-Colonel Commandant of the regiment.(b) In 1913 Mercer was aide-de-camp to Defense Minister Sir Sam Hughes during a military tour of Europe where he inspected the German Army first hand.(c) In 1914 Mercer, probably because of his close association with Sir Sam Hughes , was one of those who was called upon to help in the establishment of the Canadian Expeditionary Force that was being organized for overseas. Within days he was promoted Brigadier-General in command of the First Brigade, and in January 1916 he was made a Major-General in command of the 3rd. Division. He was killed in action at Mount Sorrel June 3, 1916.(d)
