1958 Taiwan Strait Crisis, was a conflict between the People’s Republic of China (PRC) and the Republic of China (ROC).

The PRC shelled the islands of Kinmen(Quemoy) and the Matsu Islands along the east coast of mainland China in the Taiwan Strait to “liberate” Taiwan and probe the extent of US defense of Taiwan’s territory. A naval battle also took place around Dongding Island when the ROC Navy repelled an attempted amphibious landing by the PRC Navy.
