He fought in WWII and managed to capture a German tank. Later on, one of his eyes was injured by a phosphorous grenade. He insisted that he only needed one eye to shoot and remained in the military. He stated that he “looked like a pirate”.

    He was assigned to a mission with his friend to find some missing recruits in a town. However, when his friend was ill, he had to go alone. He found the equipment of the missing recruits and assumed that they were captured. He hid in a house after it started raining and noticed two Nazi soldiers walking on the streets. He ambushed them and captured both of them. Leo managed to make the remaining soldiers surrender after he went to their commanding officer. Some nearby German troops saw that, and killed around 7 of them before Leo escaped with his captives. He captured around 93 prisoners by himself.

    Leo, armed with grenades and two Sten guns, single handedly invaded the twon of Zwolle and managed to scare off the German troops occupying the town. He was awarded a DCM twice in his life, the only Canadian to do so.
