The Battle of Kowloon (Chinese: 九龍海戰) was a skirmish between British and Chinese vessels off the Kowloon Peninsula, China, on 4 September 1839, located in Hong Kong, although Kowloon was then part of the Guangdong province. The skirmish was the first armed conflict of the First Opium War and occurred when British boats opened fire on Chinese war junks enforcing a food sales embargo on the British community. The ban was ordered after a Chinese man died in a drunken brawl with British sailors at Tsim Sha Tsui. The Chinese authorities did not consider the punishment to be sufficient as meted out by British officials, so they suspended food supplies in an attempt to force the British to turn over the culprit.
