forces to the north would tire themselves out trying to link up with the beachhead. Should the Chinese collapse in the face of a Japanese attack, then an Allied campaign to recapture Hong Kong would be jeopardized.
Japan had an incentive to retain Hong Kong. Besides being a part of Japanese-held China, Hong Kong also lay just outside Japan's Inner Zone. This zone included Japan Proper, Korea, Manchuria, North China, Formosa, the Pescadores, the Ryukyus, and the Japanese half of Sakhalin Island. Well before the war, the British had already gained an appreciation that a Hong Kong in Japanese hands would augment the defence of the Inner Zone. Moreover, Hong Kong helped guard Japan's LoC to points west and her oil supplies in the Dutch East Indies. The Japanese could still afford to trade space for time by forfeiting many other parts of their Pacific empire to the Allies, but they were certain to defend their Inner Zone and the positions that anchored their LoC to and from it with the utmost vigour. If the Japanese lost Hong Kong, this would provide hope to people living under Japanese rule elsewhere, while it would send a message to the Japanese people that the war was proceeding unfavourably for them.
By late 1943, the Allies had gained the upper hand over the Japanese in the Pacific. It was the Allies who could dictate where the next move would fall. As China was still in the game, Allied planners began to take a closer look at the feasibility of a Hong Kong campaign. One opponent the Allies couldn't overcome, however, was Mother Nature, so heed was paid to Hong Kong's weather and how it could affect an Allied campaign there.
A timeless enemy
Nature at its cruellest is a phenomenon that humanity's best efforts still cannot match. Even during a high-technology conflict like World War II, the weather proved to be as indomitable a nemesis as it had been throughout the history of war.
With World War II being fought over a greater expanse of the planet than any other war in history, its participants had to endure extreme variations in the weather, like the freezing cold of the Arctic and the Soviet Union to the sweltering heat of New Guinea, or the oppressive humidity of the South Pacific to the barren aridity of North
