evidence: On January 16, 1974, the Republic of Vietnam Navy (RVN) discovered the presence of the Chinese People’s Liberation Army (PLA) in the Crescent Group in the western Paracel Islands, which was held by South Vietnam. This was an unexpected development, because notwithstanding the reduced U.S. military assistance to Saigon after the signing of the Paris Peace Accords in 1973, and subsequent reduction of South Vietnamese garrisons on the islands, the Chinese had not taken unilateral actions to subvert the status quo – by which the Amphitrite Group in the eastern Paracels and the Crescent Group were respectively under Chinese and South Vietnamese control. Over the next two days, the opposing naval forces jostled with one another in close-proximity maneuvers off the islands, before a firefight erupted as the South Vietnamese troops attempted to recapture Duncan Island. The skirmish subsequently escalated with overwhelming Chinese reinforcements deployed to the clash zone, including close air support staged from nearby Hainan Island and missile-armed Hainan-class patrol vessels. Shorn of American naval support, given that the U.S. Navy Seventh Fleet was then scaling down its presence in the South China Sea following the peace accords of 1973, the RVN was utterly defeated. Beijing swiftly exploited the naval victory with an amphibious landing in force to complete its control of all the Paracel Islands.
