Olongapo is a city in the Philippines that houses the nearby Naval Base Subic of the United States Navy.
World War III
The city was attacked by Chinese air, naval, and special forces during the People's Republic of China's entry into World War III, which saw the destruction of some U.S. Navy and Philippine Navy ships. Both Filipino and American forces counterattacked the Chinese, in which the intense street-to-street, house-to-house fighting occurred. Parts of the city remained under Chinese control until they were reduced to a pocket, a remainder which survived to surrender to the local forces when the PRC fell and the Chinese Federated Union was established.
