Walter Carey, remained on Merapas as a guard. The rest of the party stayed in the Porpoise which moved off on the evening of 24 September 1944 to capture a native boat. It followed Karimato Strait along the Borneo coast. Capture of Mustika On the afternoon 28 September 1944 the Porpoise stopped a junk from Ketapang named the Mustika off the west coast of Borneo near Pontianak. Seven commandoes boarded the boat and nine Malay crew were taken aboard the submarine. Twelve minutes later, Porpoise submerged with both vessels making their way back west towards a forward operational base at Pedjantan Island. Over the next two nights, 29–30 September 1944, the Rimau commandoes, the SBs, folboats and other stores were transferred from Porpoise to Mustika. Once completed on 1 October 1944 the second conducting officer, Major Walter Chapman and Mustikas Malayan crew returned to Australia in HMS Porpoise. (The Malay crew would be transported to Fremantle where they stayed for the rest of the war.) Porpoise arrived safely back in Fremantle on 11 October 1944. On 15 October 1944, Chapman, along with Corporal Ronald Croton, embarked in the submarine under the command of Lieutenant Commander Hugh Mackenzie.

Return to Merapas Island Mustika returned via the Java Sea and Karimata Straits to Merapas Island. The Rimau Commandos disguised themselves as Malays by wearing sarongs and dyeing their skin. The Mustika had no engine though so the commandoes were dependent on winds. The Mustika arrived at Merapas on 4 October 1944. It appears Lyon decided to divide the party into two groups: 19 commandoes to take part in the raid, while four men would be left behind. These were meant to be Carey, Warren, Craft and Cameron or Pace. The Mustika then headed towards Singapore Harbour, reaching the vicinity of the harbour on or around 6 October 1944. It was thought to have been off the west coast of Pulau Batam. Pulau Laban is located at a distance of 11 miles from Keppel Harbour and was the intended forward point from which the attack was to be launched. Contact with Japanese On 10 October 1944, two hours before sunset and an hour before the raid was to commence, disaster struck. A coastal Malay Police patrol boat, the
