The Second Taiwan Strait Crisis, also called the 1958 Taiwan Strait Crisis, was a conflict that took place between the People's Republic of China (PRC) and the Republic of China (ROC). In this conflict, 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 from the Chinese Nationalist Party, also known as the Kuomintang (KMT); and to probe the extent of the United States 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. U.S. Secretary of State Christian Herter (1959–1961) is said to have later referred to the conflict as "the first serious nuclear crisis". Overview The conflict was a continuation of the Chinese Civil War and First Taiwan Strait Crisis. The Republic of China (ROC) had begun to build military installations on the island of Kinmen (Quemoy) and the Matsu archipelago.

The action was seen as an attempt by the communists to land on the island. This was the only naval and amphibious landing action during the crisis. The communist forces were repelled from taking the island. The action has also been seen as an attempt to draw Nationalist forces away from other areas. In the days after shelling began, the American Joint Chiefs of Staff had determined to defend the islands even if the defense necessitated a nuclear response. Throughout the following weeks as the crisis continued to unfold, contingency plans were developed as it became clear that the critical issue was supplying Kinmen. In a meeting on September 2, Secretary of State John Foster Dulles met with the Joint Chiefs of Staff and other top officials to formulate an ongoing American strategy. The group determined that the use of nuclear weapons would ultimately be necessary for the defense of Kinmen, but that the United States should initially limit itself to using conventional forces. Throughout the crisis, coordination between American policymakers and military commanders was hampered by communication delays of days at a time, but by September American officials had authorized naval
