On 30 October 1917, at Passchendaele, Belgium, during the First World War, Sergeant Mullin was serving with the Princess Patricia’s Canadian Light Infantry, Canadian Expeditionary Force.
During battle, Sergeant Mullin single-handedly captured the enemy’s “pill box” position by rushing the sniper’s post in front.
He quickly ran to the other entrance of the fortification, forcing the garrison of 10 to surrender.
His heroics were achieved under constant enemy fire.
For this action he was awarded the Victoria Cross.
Prior to the war he lived and farmed on a homestead near Moosomin.
For most conspicuous bravery in attack, when single-handed he captured a commanding ‘Pill-box’ which had withstood the heavy bombardment and was causing heavy casualties to our forces and holding up the attack. He rushed a sniper’s post in front, destroyed the garrison with bombs, and, crawling on top of the ‘Pill-box,’ he shot the two machine-gunners with his revolver. Sjt. Mullin then rushed to another entrance and compelled the garrison of ten to surrender.
His gallantry and fearlessness were witnessed by many, and, although rapid fire was directed upon him, and his clothes riddled by bullets, he never faltered in his purpose and he not only helped to save the situation, but also indirectly saved many lives.
