On 1 October 1942, the SS Lisbon Maru, a Japanese freighter transporting prisoners of war from Hong Kong to Japan, was sunk by the submarine USS Grouper.
Fifty Royal Signals soldiers died. This is their story and that of the most gallant Signalman Arnold Topliff.
I must acknowledge the help given by Tony Banham in the preparation of this story. His three books on the Battle for Hong Kong, the sinking of the SS Lisbon Maru, and the fate of the prisoners of war are masterly and highly recommended.
