Tableau de chasse du sous-marin inconnu      A mysterious German submarine launches a torpedo that did not hit any ships and was sent to the bottom of the St. Lawrence River. Over 35 years later, the front of this torpedo was caught in a fishing net offshore les Méchins. The fishermen brought back the torpedo that the Royal Canadian Mounted Police exploded in a wasteland close to Rivière-aux-Renards. A fragment from this torpedo is kept at the Naval Museum of Quebec.
