My great-great grandfather was a munitions worker during world war one. I found a newspaper article that indicates that he was on his way from Canada to England when the ship he was on was torpedoed. The article does not indicate whether this was a military or civilian ship or what the name of the ship is. I'd like to try to find out what ship it was. Does anyone now a website with a thorough list of ships that were sunk, or does anyone know if there is a database of passenger lists for ships travelling during wartime?

Here is the article;

London Evening News Tuesday, October 9, 1917, London, Middlesex Back to the Old Love: A munition worker, Henry Ferdinand Platt, 38, plead guilty to bigamy and was bound voer to-day at the Old Bailey. Prisoner was in Canada when the war broke out. On the way to England his ship was torpedoed. He was in the water five hours, but was rescued. After that, counsel said "he seemed to go a little crazy". He met a girl in a munition factor and "married" her. His real wife, with whom he had lived happily for seventeen years, came to England and brought her large family with her. Prisoner went back to her and confessed bigamy to the authorities.
