. Some POWs became delirious and unresponsive in their environment of heat, humidity and lack of oxygen, food, and water. These transports carried a mixture of POWs and regular Japanese troops and cargo, and thus were not eligible to be marked as non-combatants. As a result, such vessels could be attacked by Allied submarines and aircraft, meaning they were at risk of being sunk before they even reached their destination. More than 20,000 Allied POWs died at sea when the transport ships carrying them were attacked by Allied submarines and aircraft.

Only nine of the prisoners aboard survived the event. Five escaped and made their way to China in one of the ship's two life boats.
