Burma prisoner transport

[Rick W]

Have a friend who wears a her grandfathers medals to remembrance Sunday. One of them is the Burma Star, but he was lost at sea. Im wondering if he was a POW on board one of the prisoner freighters transferring POWs to Burma. I cant remember what the freighter was called, but do recall one being torpedoed by the US. Can anyone tell me what the ship was called and if there are any links to the men lost on board?
