The United States Army Air Forces and United States Navy conducted numerous air raids against Japanese-occupied Hong Kong and shipping near the city during World War II. The Royal Australian Air Force took part in efforts to lay naval mines in the Hong Kong area. These attacks began in 1942. In 1945 it was incorporated into the larger South China Sea raid. British Pacific Fleet aircraft also attacked Japanese suicide boats at Hong Kong as part of the reoccupation of the colony in late August 1945.
