Heading for Halifax to join a convoy, she struck an unknown object near Sambro Island and soon sank. Her crew took to lifeboats and all safely reached the Sambro lighthouse. The cause was first thought to be a torpedo, but no German submarines reported an attack and none were recorded in the area. More likely she was off course and struck one of the ledges aground Sambro. Her wreck was salvaged after the war. Today it attracts divers and underwater photographers, especially for the tanks carried as deck cargo.
