The Heroine of Singapore — Part 4: The battery, the blade and those who chose death over betrayal
In Extremis - Stories from the Edge of HistoryShow Notes
A warning before we start — this episode contains detailed descriptions of torture and extreme physical and psychological violence. Probably not one to have on in the car with the kids. Research for this episode comes from my book Survival in Singapore.
Summary By the time this episode begins, Sumida Haruzo's investigation has been running for months. Dozens of British internees have been arrested and interrogated. Scores — possibly hundreds — of Chinese civilians have passed through the cells of the YMCA on Stamford Road. And Sumida has almost nothing to show for it. The radios in Changi were receivers, not transmitters. The money was funding a black market, not a sabotage operation. Elizabeth Choy had been helping the internees. Robert Heatlie Scott had been running a news committee. There was no fifth column. There was no conspiracy. And yet Sumida pressed on. In this episode we examine why and the answer says something uncomfortable about the nature of confirmation bias, institutional pressure, and what happens when a man of intelligence and ambition becomes too invested in a theory to abandon it. But the heart of this episode belongs to the people in the cells. Elizabeth Choy is subjected to electrocution while bound to a wooden frame, unable to move. She does not break. Then she and her husband Choy Khun Heng are brought into the same room, and the sadist Sgt Monai Tadamori deploys the cruelest instrument available to him: he tortures Elizabeth in front of her husband, and her husband in front of her. Both are told that tomorrow they will be executed. Alone together in the room, they reach an agreement. If they are to die, they will die for the truth. It would be an honourable death. A confession, they know, would cost others their lives. Then there is Robert Heatlie Scott. Scott has spent three months preparing for what is coming. He has reframed torture not as a horror to be feared but as an enemy tactic to be countered. He knows he will probably not survive. What matters is that nothing he says broadens the investigation. Nothing he says costs anyone else their life. When Monai finally comes for him — six days of sustained physical violence, sleep deprivation, the rack, the instruments laid out across the floor — Scott doesn't break. His answers never waver. And on the sixth day, when Monai places a farewell letter on the ground before him and draws his sword, Scott remains unmoved. The fate of Elizabeth Choy and Robert Heatlie Scott — and the final reckoning of Sumida Haruzo's investigation — will be told in the concluding episode of the Heroine of Singapore arc, next week on In Extremis.

Nehvizdy, December 1941. Two parachutists land in an open field of snow, miles from their drop zone. One is injured. By first light, a stranger has found their buried parachutes and followed their footprints to the quarry where they’re hiding. Operation Anthropoid is only hours old, and already on the brink of disaster. In Part 2, we follow Jozef Gabčík and Jan Kubiš through five months in occupied Prague. They break the most important rule of their mission to survive, rely on the families who risk everything to hide them, and patiently track the most dangerous man in the Protectorate. As the day of the attack approaches, the Czech resistance begs London to call it off. Then we spend a final morning with Reinhard Heydrich, a man at the height of his power, with no idea what is waiting for him on the road into Prague.

Prague, 27 May 1942. Two men wait at a hairpin bend on a quiet suburban road. One carries a briefcase holding an anti-tank grenade. The other is assembling a Sten gun beneath a raincoat. Their target is Reinhard Heydrich, head of the Nazi security apparatus, ruler of occupied Bohemia and Moravia, and the man who chaired the Wannsee Conference. In Part 1, we go back to how Heydrich seized control of the Protectorate, the reign of terror that earned him the name “the Butcher of Prague,” and the political calculations in London that set Operation Anthropoid in motion. Then we board an overcrowded Halifax bomber over snow-covered Bohemia, as two Czechoslovak soldiers prepare to jump into the night.

February 1912. Lieutenant Teddy Evans is dying of scurvy in a tent on the Ross Ice Shelf. Hut Point is 56 km away. There is food for two days at most. Tom Crean pockets a few biscuits and a little chocolate, and starts walking. Part 2 picks up where we left off, with three men on a runaway sledge on the Shackleton Icefalls. Crean, Evans and William Lashly then pick their way down the Beardmore Glacier through a maze of crevasses, crossing one chasm on a knife-edged snow bridge with the sledge balanced on its peak. Far to the south, Scott reaches the Pole and finds Amundsen's tent waiting for him. Then scurvy takes hold of Evans. Crean and Lashly haul him on the sledge for around 100 km. Evans orders them to leave him and save themselves. They refuse. With the rations almost gone, one man has to go for help alone. Crean had done it before. A year earlier, adrift on breaking sea ice with Henry Bowers and Apsley Cherry-Garrard and killer whales circling, he leapt from floe to floe and climbed the face of the Barrier to raise the alarm. This time he sets out exhausted, half-starved and without water. He walks for around 18 hours with a single five-minute rest, and reaches Discovery Hut half an hour ahead of a blizzard.

Tom Crean's Long Walk, Part 1: The Last Supporting Party January 1912. Tom Crean stands 268 km from the South Pole, the dream of a decade within a fortnight's march. Then Captain Robert Falcon Scott sends him home. Tom Crean was the raw-boned Kerryman who served on Discovery, Terra Nova and Endurance, and was there for the defining moments of all three. In Part 1 we follow him up the Beardmore Glacier as Scott's party closes in on the Pole, unaware that Roald Amundsen has already beaten them to it. We look at Scott's controversial choice to keep his men guessing about who would make the final push, and his last-minute decision to take five men instead of four. That call upended a plan built around fours and left Crean, William Lashly and Lieutenant Edward Evans facing a 1,200 km journey home with a single navigator, thin air, failing bodies and a closing season. Along the way: a Christmas Day crevasse fall, Crean's wit at the lip of the abyss, the moment Crean wept, snow blindness on the plateau, and a desperate gamble at the Shackleton Ice Falls that sends three men hurtling towards a black void.

Tom Trumble speaks at Reflections at Bukit Chandu, a WW2 and social history museum in Singapore, on the subject of his fourth book, Survival in Singapore: Elizabeth Choiy, Operation Jaywick, and the Battle for Truth in Changi (Penguin Random House, 2025). The presentation occurred on 12 September, marking the 81st anniversary of the liberation of Singapore and the end of the Japanese Occupation. Bukit Chandu—Malay for Opium Hill—overlooks the harbour where Operation Jaywick, a devastating commando mission, mined and destroyed Japanese ships. The museum sits at the edge of the Battle of Pasir Panjang, where the First Malay Regiment made their last stand under Second Lieutenant Adnan bin Saidi before the British surrender. Bin Saidi was captured and executed by the Japanese, and is regarded as a national hero. This presentation examines the unforeseen consequences of Operation Jaywick and the stories of survival and resistance during the Japanese occupation of Singapore.
