targets and later rendezvous with the junk to participate in the attack; two canoes would travel north to the vicinity of Labon Island to secure a hide for the junk and for another canoe to proceed to Subar; after darkness, the crew was to move the junk to an attack base at Labon using the "Sleeping Beauties", the party was to attach limpet mines to Japanese ships, sink thirty of them, damage another thirty, and escape to their base on Merapas Island by paddling their way back in two-man folboats (collapsible canoes), seventy miles to the east of Singapore; return to a rendezvous with the submarine on 7/8 November 1944 at Merapas Island; if the submarine failed to make contact with them it would stay in the area, returning to the designated point every night until 8 December 1944. The main differences from Operation Jaywick were: delivering mines by special one-man motorised submersible canoes (called ‘Sleeping Beauties’, or SBs); a larger operational team (23 as opposed to 14); capturing a boat rather than sailing in one from Australia; the boat captured did not have an engine. The members of the team were: Lieutenant Colonel Ivan Lyon*, Lieutenant Commander Donald Davidson, RNVR*; Major Reginald Ingleton, RM; Captain Robert Page*; Lieutenant Bruno Reymond, RANR; Lieutenant Walter Carey – conducting officer, Lieutenant Robert Ross, Lieutenant Albert Sargent, Lieutenant Walter Chapman – conducting officer; Sub-Lieutenant Gregor Riggs, RNVR Warrant Officer Alfred Warren; Warrant Officer Jeffrey Willersdorf – Maintenance Technician.; Sergeant Colin Cameron – Maintenance Technician; Sergeant David Gooley – Maintenance Technician; Corporal Archie Campbell; Corporal Colin Craft – signaller; Corporal Roland Fletcher – Infantry and Maintenance; Corporal Hugo Pace – Infantry and Maintenance; Corporal Clair Stewart – signaller; Lance Corporal John Hardy – Infantry and Maintenance; Able Seaman Walter Falls*; Able Seaman Andrew Huston; Able Seaman Frederick Marsh*; Private Douglas Warne – Infantry and Maintenance (* means participated in Operation Jaywick) Operation Lyon and his men left their base in Garden Island in Western Australia aboard the British submarine HMS Porpoise on 11 September 1944. The submarine reached the island of Merapas off the coast of Pulau Bintan on 23 September 1944. Although the island was believed to be uninhabited, a periscope reconnaissance the following day spotted three Malays beside a canoe on the beach. To ensure that their stores would remain undiscovered by the natives, one of the officers from the Porpoise, Lieutenant
