Battle of Hong Kong

The Battle of Hong Kong (8–25 December 1941), also known as the Defence of Hong Kong and the Fall of Hong Kong, was one of the first battles of the Pacific War in World War II. On the same morning as the attack on Pearl Harbor, forces of the Empire of Japan attacked the British Crown colony of Hong Kong around the same time that Japan declared war on Britain. The Hong Kong garrison consisted of British, Indian and Canadian units, the Auxiliary Defence Units, and the Hong Kong Volunteer Defence Corps (HKVDC).

Of the three territories of Hong Kong, the defenders abandoned the two mainland territories of Kowloon and New Territories within a week. Less than two weeks later, with their last territory Hong Kong Island untenable, the colony surrendered. The fall of the city is regarded as Black Christmas as it marked the beginning of a brutal occupation by Japan that would last until its liberation in the summer of 1945. Britain's defeat in Hong Kong alongside the Fall of Singapore in 1942 would irreparably damage its reputation in Asia as a major military power.

Background

Britain first thought of Japan as a threat with the ending of the Anglo-Japanese Alliance in 1921, a threat that increased throughout the 1930s with the escalation of the Second Sino-Japanese War as well as the Japanese invasion of French Indochina. On 21 October 1938, the Japanese occupied Canton (Guangzhou) and Hong Kong was surrounded. British defence studies concluded that Hong Kong would be extremely hard to defend in the event of a Japanese attack, but in the mid-1930s work began on improvements to defences including along the Gin Drinkers' Line. By 1940, the British determined to reduce the Hong Kong Garrison to only a symbolic size.
