The Amoy Operation, also known as the Battle of Xiamen (Chinese: 廈門戰鬥) was part of a campaign by Japan during the Second Sino-Japanese War to blockade China to prevent it from communicating with the outside world and importing needed arms and materials. Control of Amoy Island would provide a base to make the blockade of Fujian province more effective.

Like the Canton Operation, the Amoy Operation was overseen by Koichi Shiozawa (1881-1943), who was the commander-in-chief of the Fifth Fleet during the Second Sino-Japanese War (1937-1945).^[1] The fleets warships bombarded the city to cover the landing of more than 2,000 invading troops.^[2] The poorly equipped defenders of the city were forced to withdraw and move to Sung-yu.^[2] The blockade was successful so that China's ability to counterattack was effectively crippled.^[3]
