Singapore is both the turning point that places Australian prisoners in Japanese hands and the last known point of contact for many families before the men disappear into the forced-labour system. The city’s fall in February 1942 leads, in the novel’s account, toward Changi, the transfer of Evans’ J Force, and the later effort to reckon with the human cost of the railway built far to the north.

Strategic Turning Point

The story’s historical frame begins with the fall of Singapore on 15 February 1942, when one empire ends and another rises. By 1943, the Japanese Empire is losing ground and needs a land route through Burma to supply its forces and threaten India. The Allies supply China through Burma, while American control of the seas makes a railway increasingly important to Japanese strategy. Japan lacks the machinery, money, and time to build it by ordinary means; the project instead depends on the forced labour of prisoners and other enslaved workers.

The scale of that system makes Singapore consequential beyond the island itself. The Japanese Empire holds 22,000 Australian prisoners of war, most of them surrendered at Singapore as a strategic necessity before the fighting had properly begun. Nine thousand are sent to work on the railway. The line’s eventual completion therefore reaches back to the surrender: men captured at Singapore are made part of an immense engineering project whose military purpose does not lessen its human cost.

Changi and the Transfer of Evans’ J Force

Singapore becomes a transit point in the movement of prisoners from Java toward work in Siam. After six months, a thousand men are taken by boat to Singapore and marched to Changi Gaol. Their arrival exposes a sharp disparity among Australian prisoners. Changi’s established inmates occupy airy barracks and have access to gardens and provisions; the newly arrived men are emaciated, dressed in mismatched Australian and Dutch uniforms, and often without shoes. The commander of the Australian prisoners at Changi, Brigadier Crowbar Callaghan, calls them Java Scum and refuses Dorrigo Evans’ requests for clothes, boots, and supplies. He also tries, unsuccessfully, to remove Dorrigo as commander because of his insistence that the stores be opened.

The men’s stay at Changi is brief. Two weeks later they leave in the same rags in which they arrived, now officially designated Evans’ J Force. They are packed into small steel railway wagons built to carry rice, with twenty-seven men in each wagon and too little room to sit. The journey takes five days; they travel without food, make six stops, and three men die before the survivors are taken off at Ban Pong. Singapore is thus neither their final destination nor the site of the railway works. It is the passage through which a named military unit becomes a captive labour force bound for the interior.

Captivity, Absence, and the Record of Atrocity

The movement from Singapore also marks a break in communication. Families can correspond with Australian prisoners in Germany, but the men held in Asia are beyond reliable news. Nine months after the surrender, there has been no word of Dorrigo’s unit; people are told that thousands of prisoners may have died, though there is no proof that Dorrigo himself is dead. Singapore remains the reference point from which that silence is measured: the surrender is known, but the fate of those carried away from it is not.

The city also appears as a place where the violence of occupation is recorded and remembered. When Bonox Baker opens a book to an ink drawing of Chinese men executed after the Japanese occupation of Singapore, the image prompts Dorrigo to confront the distance between documenting atrocity and recovering the dead. He cannot summon the face he tries to remember. The scene links Singapore’s record of occupation to the novel’s wider concern with memory: a written or drawn account can preserve evidence, but it cannot restore what has been lost or make remembrance complete.

The Railway’s Human Cost and Singapore’s Afterlife

The railway that begins as survey pegs and a projected route becomes a completed line on 25 October 1943, when locomotive C 5631 travels its length with Japanese and Thai dignitaries aboard. The construction has consumed the lives of prisoners and Asian labourers. Of the Australians sent to work on it, one in three will die. The full toll remains uncertain: Allied prisoners are only part of a labour force that also includes a quarter of a million Tamils, Chinese, Javanese, Malayans, Thais, and Burmese, or more. Estimates of deaths among these labourers vary widely, and no agreed total exists.

That uncertainty gives Singapore’s historical role a double edge. It is the place associated with a decisive surrender and the departure of prisoners, but it cannot contain the whole story of what followed. The railway is later abandoned and dismantled; its traces are gradually reclaimed by the landscape. The memorial display of C 5631 at the Yasukuni Shrine in Tokyo preserves the locomotive, yet its plaque does not name the horrors of construction or the dead who built the line. Singapore’s place in the novel is therefore less a monument than a point of departure: from the captured men who leave Changi to the lives and deaths that official records, incomplete testimony, and uncertain counts struggle to encompass.
