My girlfriends Grandfather (now deceased) was once in the Merchant Navy during the Second World War and was reportedly sunk twice. We are trying to find out more about what he did. Is there any way that we can get more information on the Merchant Navy convoys during the Second World War? I.e. what ships were involved, and maybe even a record of who sailed on those ships. ( I know the Merchant Navy is civvy but perhaps these things exist)? Also amongst his belongings we found what at first appeared to be a gold coin, however upon inspection i believe it to be some kind of medal(?). I have researched the ship, but wondered if this was a medal or a souvenir? There are no details on the edging of the coin, it is just blank. I wondered why this would be issued? Any information whatsoever (even links for the relevant websites) would be great, as i know nothing about shipping in the second world war.
