Qing notables on Taiwan disagreed with the concession of territory to Japan as stipulated by the treaty negotiated by the mainland. They vowed to resist Japanese occupation and proclaimed the establishment of a short-lived Republic of Formosa. Japan reacted to the news of the rebellion by deploying naval military forces stationed at Port Arthur for the Japanese invasion of Taiwan (Traditional Chinese: 乙未戰争) (May–October 1895), a five-month conflict that delayed Japanese control of the former Chinese territory. The quickness of the announcement of the rebellion and the Japanese military deployment from Port Arthur gave the Japanese little time to exchange the equipment on hand suitable for the northern climate of Manchuria and the port instead of the tropical climate of the ceded islands.
