In all, eleven members of the contingent were captured and brought to Outram Road Prison in Singapore.
One commando, Marsh, died of malaria.
During the imprisonment the men were tortured and provided starvation rations similar to those provided to other prisoners in the facility.

On 3 July 1945, they were put on trial for perfidy and espionage.
They were found guilty and sentenced to death.

Official Japanese records state that the ten men were beheaded at Pasir Panjang on 7 July 1945, approximately one month before World War II in the Pacific came to an end.
Later evidence stated it took guards more than half an hour to execute the men, sometimes requiring two or three blows to complete beheading.

The men executed were
Major Reginald Ingleton,
Captain Robert Page,
Lieutenant Albert Sargent,
Lieutenant Walter Carey,
Warrant Officer Alfred Warren,
Sergeant David Gooley,
Corporal Clair Stewart,
Corporal Roland Fletcher,
Able Seaman Walter Falls,
Lance Corporal John Hardy
The bodies were dumped in three unmarked graves.

Nineteen of the Rimau commandos, including Lyon, are buried at Kranji War Memorial in Singapore.
The bodies of two men (Riggs and Cameron) were discovered on Merapas Island in 1993 with the help of locals present on the island at the time of their death and transferred to Singapore for burial in August 1994.
