 After sinking NICHINAN MARU, Lt Pelly took HMS STRATAGEM to lie in ambush off the port of Malacca, Malaya, but on 22 Nov '44 she was detected by an aircraft, depth-charged by a surface vessel (presumably CH-35) and sunk. Ten of her crew escaped and, suffering from the "bends", were picked by the Japanese. Seven died in captivity.
4 One Japanese source (Komamiya) lists the destination as Saei rather than St Jacques, but this is probably an error since it is unlikely the convoy could make Formosa in three days even sailing direct and another Japanese source confirms St Jacques with an exact arrival time.
Thanks to Mr. Gilbert Casse of France for general assistance.
