The Hong Kong garrison competed with Singapore's wider strategy

The argument begins from the premise that Hong Kong could not be secured against a full Japanese attack. It then poses a counterfactual in which one credible supreme commander controlled the Indian Ocean, Southeast Asia, Australasia, and the South China Sea. Under that command structure, Hong Kong's reinforcements would have gone to Singapore. Concentration there would have matched the earlier British concept for defending the region and avoided dispersing scarce forces. The passage turns a local garrison question into a wider lesson about theater command, force allocation, and maritime strategy.
