Hong Kong fell to Japanese forces on Christmas Day, 1941, after 18 days of fighting. The British crown colony's surrender was one of the largest in British military history, with nearly 11,000 soldiers — British, Canadian, Indian, and local Hong Kong volunteers — taken prisoner. They needed to be housed somewhere.

Argyle Street Camp had originally been built by the Hong Kong government as a refugee camp before the war. Its purpose shifted immediately after Kowloon and the New Territories were abandoned to Japanese forces. Within weeks of the surrender, it became a prisoner-of-war camp. In January 1942 it was briefly emptied, its prisoners transferred to Shamshuipo, North Point, and Ma Tau Chung Camps as the Japanese reorganized their detention arrangements. The camp then stood empty for a few months — but not for long.

A series of escapes changed Argyle Street's function. After Allied officers and other ranks broke out of Shamshuipo, Japanese authorities decided that officers required a more controlled environment. Argyle Street was reopened in mid-1942 specifically as an officers' camp — a distinction that mattered in the hierarchies of prisoner-of-war administration, where officers were technically entitled to separate conditions under the Geneva Convention, though Japan had not ratified that convention.

For the officers held there, captivity at Argyle Street meant years of crowded, under-resourced confinement on the Kowloon peninsula they had failed to defend. Rations were inadequate, disease was constant, and the uncertainty of the war's outcome hung over every day. In 1944 the officers were moved again — this time to Camp N at Shamshuipo — and their place was taken by Indian POWs transferred from Ma Tau Chung Camp, a different population with its own story of displacement and imprisonment far from home.

When Japan surrendered in August 1945, the camp's function changed again, but the camp itself did not. It became a processing centre for displaced people returning to Hong Kong — a transit point in a city trying to reconstitute itself after nearly four years of occupation. The population cycling through its gates shifted with the politics of the surrounding region, as upheaval in mainland China and Southeast Asia sent successive waves of people toward the colony.

By the late 1970s, the camp was absorbing a new emergency. Vietnam's wars and their aftermath sent hundreds of thousands of people by boat toward the coast of Southeast Asia. Hong Kong became one of the primary destinations for Vietnamese boat people, and Argyle Street Camp was pressed into service as a refugee facility. In June 1979, it began accepting Vietnamese refugees, with authorities planning for a capacity of 20,000 people in a site built for far fewer.

What is striking about Argyle Street Camp today is not what remains but what does not. Other sites of wartime imprisonment in Hong Kong have been marked — the Stanley Internment Camp has plaques and a museum; Shamshuipo has memorials. Argyle Street has nothing. The site lies in a busy urban neighbourhood, overlooked by a working hospital, and the ground gives no indication of what it held: the Allied officers counting days in 1942, the Indian prisoners who replaced them, the Vietnamese families who waited there for resettlement decisions that would determine the rest of their lives.

History tends to accumulate memorials around places associated with great battles or famous dead. The quieter suffering of detention — the years of waiting, the slow erosion of captivity, the lives suspended inside wire — leaves less visible marks. At Argyle Street, it has left none at all.
