Qiongzhou Strait
Battle of Nanpéng Island (南鹏岛战斗) was a battle fought between the nationalists and the communists during the Chinese Civil War and resulted in the communist victory. After Guangdong fell into communist hands, a detachment of the nationalist troops held out on Nanpéng Island (南鹏岛) of Yangjiang. This remnant of the nationalist force proved to be a major headache the communists because the island is strategically located between the Pearl River mouth and the Qiongzhou Strait, controlling the shipping line that was vital to the local economy.
