The Battle of Pungdo (Japanese: 豊島沖海戦, romanized: Hoto-oki kaisen) was the first naval battle of the First Sino-Japanese War. It took place on 25 July 1894 off Asan, Chungcheongnam-do, Korea, between cruisers of the Imperial Japanese Navy and components of the Chinese Beiyang Fleet. Both China and Japan had been intervening in Korea against the Donghak Peasant Revolution. While China tried to maintain its suzerain relationship with Korea, Japan wanted to increase its sphere of influence. Both countries had already sent troops to Korea as requested by different factions within the Korean government. Chinese troops from the Huai Army, were stationed in Asan, south of Seoul, numbering 3,000 men in early July, could be effectively supplied only by sea through the Bay of Asan. The Japanese plan was to blockade the entrance of the Bay of Asan, while its land forces moved overland to encircle the Chinese detachment in Asan before reinforcements arrived by sea.
