The conflict was a continuation of the Chinese Civil War and First Taiwan Strait Crisis. The Republic of China had begun to build military installations on the island of Kinmen and the Matsu archipelago. The Chinese People's Liberation Army began firing artillery at both Kinmen and some of the nearby Matsu islands. On August 24 and 25, 1958 Chinese Communist and Chinese Nationalist forces clashed in the vicinity of Dongding Island, which the Nationalist troops controlled. 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. The American Eisenhower Administration responded to the request for aid from the ROC according to its obligations in the ROC-United States mutual defense treaty that had been ratified in 1954. President Dwight D. Eisenhower ordered the reinforcement of the U.S. Navy Seventh Fleet in the area, and he ordered American naval vessels to help the Nationalist Chinese government to protect the supply lines to the islands. In addition, the U.S. Air Force deployed F-100D Super Sabres, F-101C Voodoos, F-104A Starfighters, and B-57B Canberras to Taiwan to demonstrate support for the republic. The F-104s were disassembled and airlifted to Taiwan in C-124 Globemaster II transport aircraft, marking the first time such a method was used to move fighter aircraft over a long distance. in September 1958. Also, under a secret effort called "Operation Black Magic", the U.S. Navy modified some of the F-86 Sabre fighters of the Nationalist Chinese Air Force with its newly developed early AIM-9 Sidewinderair-to-air missiles. These missiles gave the Nationalist Chinese pilots a decisive edge over the Chinese Communists' Soviet-made MiG-15 and MiG-17 fighters in the skies over the Matsu Islands and the Taiwan Strait. The Nationalist Chinese pilots used the Sidewinder missiles to score numerous kills on People's Liberation Army Air Force MiG aircraft. The US Army's contribution reinforced the strategic air defense capability of the Republic of China. A provisional Nike missile battalion was organized at Fort Bliss, TX, and sent via USMTS to Nationalist China. The 2nd Missile Battalion was augmented with detachments of signal, ordnance and engineers, totaling some 704 personnel. Twelve long-range M115 howitzer artillery pieces and numerous 155 mm howitzers were transferred from the U.S. Marine Corps to the Army of the Nationalist China. These were sent west to Kinmen Island to gain superiority in the artillery duel back and forth over the straits there. Soon, the Soviet Union dispatched its foreign minister, Andrei Gromyko, to Beijing to discuss the actions of the PLA and the PLAAF, with advice of caution to the Communist Chinese. On, the Sidewinder missile was used for the first time in air-to-air combat as 32 Republic of China F-86s clashed with 100 PLAAF MiGs in a series of aerial engagements. Numerous MiGs were shot down by Sidewinders, the first "kills" to be scored by air-to-air missiles in combat. Soon, the People's Republic of China was faced with a stalemate, as the PLA's artillerymen had run out of artillery shells. The Communist Chinese government announced a large decrease in bombardment levels on. U.S. Marine Corps Marine Air Group 11 stationed at NAS Atsugi, Japan was sent to Taiwan in August and landed at Kaohsiung, Taiwan and moved via trucks to Ping Tung Air Base about 25 miles north of Kaohsiung. They remained there, conducting air operations from the WWII Japanese air strip until sometime in the spring of 1959 when they returned to Atsugi. They were joined at Ping Tung by a reinforced rifle company from the Ninth Marines based on Okinawa.
Aftermath
Afterwards, both sides continued to bombard each other with shells containing propaganda leaflets on alternate days of the week. This strange informal arrangement continued until the normalization of diplomatic relations between the United States and the Communist People's Republic of China in 1979. The timed shelling created little damage and casualties; it was mainly aimed at military compounds and artillery pieces. On August 23, 2019, the sixty-first anniversary of the beginning of the Second Taiwan Strait Crisis, President Tsai Ing-wen visited the Taiwushan Martyrs' Shrine where she placed flowers and offered incense.
