The Sergeant Harry Mullin Plaque was erected by the Saskatchewan Heritage Foundation, Government of Saskatchewan in 1995. This was the location of Mullin's homestead.
George Harry Mullin was born in Portland, United States, on 15 August 1891. When he was two, his family moved to Canada, settling in Moosomin, Saskatchewan. During the First World War, Mullin served in the scout and sniper section of Princess Patricia’s Canadian Light Infantry, Canadian Expeditionary Force. For his conduct on the occasion of the successful attack by the Canadian Corps on Vimy Ridge in April 1917, he received the Military Medal.
On 30 October 1917 near Passchendaele in Belgium, a company of the PPCLI was attempting to eliminate a German “pillbox” fortification that was blocking its advance and causing heavy casualties. While one group of Patricias led by Lieutenant Hugh McKenzie made a frontal attack on the pillbox and drew its fire, Sergeant Mullin approached from the flank and crawled onto the top of the concrete structure, disposing of an enemy sniper’s position on the way. From this vantage point, Mullin shot two German machine gunners with his revolver before compelling the other ten occupants of the pillbox to surrender.
For the courage he demonstrated in this action, Sergeant Mullin was awarded the Victoria Cross.
Mullin died in Regina, Saskatchewan on 5 April 1963.
