Operation Causeway
Operation Causeway was a planned United States invasion of Formosa (Taiwan), the Quemoys (Kinmen Islands), and Xiamen Bay on the southeastern coast of Mainland China during World War II. At that time, Formosa was a Japanese colony since the nineteenth century. The island was seen as a possible next step in the planned Allied "island-hopping" advance across the Pacific after the capture of the Marianas in mid-1944.
