Whether Poon Lim understood this explicitly or simply did it because it was what a person in his situation would naturally do — because the alternative was to sit still and wait and lose the thread of himself — is not something the sources resolve. The outcome resolves it in the only way that matters: he maintained coherent function across one hundred and thirty-three days of solitary isolation, and the cognitive capacity that allowed him to give an account of his experience after rescue was the same cognitive capacity that had sustained his survival throughout.
## The Postwar Merchant Navy and Poon Lim’s Career
When Poon Lim joined United States Lines as a messman in the mid-1940s, he entered an institution that was itself undergoing significant transformation in the immediate postwar period. The American merchant marine had expanded dramatically during the war, producing a fleet that was by 1945 the largest in the world, built on the Liberty Ship and Victory Ship programs that had turned the country’s industrial capacity toward rapid production of standardized cargo vessels. The postwar period would see a significant contraction of this fleet as wartime production was retired and the shipping industry reconfigured for peacetime trade.
United States Lines was one of the established American shipping companies that survived and operated through this period. Its routes covered the North Atlantic passenger and cargo trade, and its vessels ranged from passenger liners to cargo ships of the type that would have been familiar to anyone trained in the wartime merchant marine. As a messman and eventually a steward, Poon Lim was working the same service and catering specialty that he had developed as Second Mess Steward on the Benlomond — the management of food service and hospitality for officers and passengers.
