In the closing stages of WWII a group of top British and Australian commandos were selected for the biggest covert operation of the Pacific War. Operation Rimau (Malay for "Tiger") was an ambitious plan to penetrate Singapore Harbour in top-secret one-man submarines called "Sleeping Beauties" and launch an attack on 60 Japanese ships at anchor.
Led by a Harrow-educated veteran, Lieutenant Colonel Ivan Lyon, Operation Rimau was designed as a body blow to the Japanese. But, as the commandos infiltrated Japanese-occupied waters near Singapore, things went horribly wrong.
Due to bureaucratic fumbling and incompetence, the submarine detailed to pick up the men did not arrive. All of them were captured and eventually executed by the Japanese. The authors reveal for the first time what really happened to the Rimau commandos, their betrayal and brave last stand.
