The East Sea Campaign was a naval operation which took place during the closing days of the Vietnam War in April 1975. Even though it had no significant impact on the final outcome of the war, the capture of certain South Vietnamese-held Spratly Islands (Trường Sa) in the South China Sea (referred to by the Vietnamese as the East Sea), and other islands on the southeastern coast of Vietnam by the Vietnam People's Navy (VPN) and the Viet Cong helped the Socialist Republic of Vietnam assert its sovereignty over the various groups of islands after the reunification of the country in 1975. The North Vietnamese objective was to capture all the islands under the occupation of the Army of the Republic of Vietnam (ARVN), and it eventually ended in complete victory for the North Vietnamese.
