Hellfire Pass was an important part of the Burma-Thailand Railway. The railway was built to create a land route between Burma and Thailand, avoiding sea routes that were risky due to Allied attacks.

This route was established to help the Imperial Japanese Army operations in Burma by allowing troops, weapons, and supplies to move safely between Thailand and Burma.

Work on the section of railway that includes Hellfire Pass started on Anzac Day 1943 in the thick jungles. Large amounts of rock had to be cleared to lay the railway tracks. Allied prisoners of war and rōmusha were forced to do this hard work.

Without appropriate tools for such work, the men had to use hammers and chisels to break through solid rock. The ordeal was made worse by a lack of food, cruel and brutal treatment, and the spread of disease.

Prisoners and rōmusha often toiled for up to 18 hours a day under the constant threat of violence. The name ‘Hellfire Pass’ comes from the sight of the sick, starving men who worked by torchlight, which resembled a scene from hell.

The railway through Hellfire Pass was finished quickly, but at great human cost. The horrific treatment and poor conditions caused great suffering and many deaths during the building of the Burma-Thailand Railway.

Prior to World War II

Initial concept by the British Government

The British colonial government first considered building a railway through the thick jungles of the Tenasserim Hills. The hills separate Thailand and Burma (present day Myanmar). Upon review it was decided that the railway would be too difficult and costly to build due to the rough terrain and the safety risk to workers.

Japanese invasion

With the onset of war in the Pacific, Japanese forces launched their initial attacks across South-East Asia, including by invading the Malay Peninsula and Thailand. They subsequently also invaded other areas, including the Netherlands East Indies. In all areas, they quickly overpowered the defences.

Japanese decision and planning

By mid-1942, the Japanese forces had control of Thailand and parts of Burma. To support their military efforts, the Imperial Japanese Army decided to build the Burma-Thailand Railway because transporting men and material to Burma by sea was too dangerous.

Work begins on Burma-Thailand Railway

Construction on the railway began in October 1942. For 12 months, prisoners and rōmusha suffered in brutal conditions with limited food, fresh water, medical supplies, or shelter. Physical violence was used towards the prisoners and rōmusha to speed up process and ensure compliance.

Hellfire Pass

On 25 April 1943, work began on the Konyu cutting, known as Hellfire Pass. From July, prisoners were forced to work 12-18 hours shifts with no rest day. This period, known to prisoners as ‘speedo’, remained until the completion of the Hellfire Pass section in August 1943. The death rate at Hellfire Pass was 8 to 10 per cent higher than other parts of the railway.

Completion of the Railway

The railway was finished in just 12 months due to the exploitation and cruel treatment of the prisoners and rōmusha. Sadly, many died from malnutrition, harsh conditions, brutality and disease.

Railway use

Once complete, Japanese forces used the railway to move troops and supplies. Allied forces bombed it often to disrupt these operations. Some prisoners and rōmusha were retained to repair and work on the railway after it was completed. The rest of the prisoners were transferred to other camps in the Pacific.
