The Eisenhower administration worried that the surrender of any Taiwanese territory would have such a demoralizing effect on the Republic of China government that it could cause the collapse of Chiang Kai Shek's regime. A second crisis erupted in 1958 to a considerably more deadly effect. A Chinese attempt to seize the small island of Dongding was repulsed, which triggered a massive PLA artillery response that killed over 500 Taiwanese soldiers. This time the crisis also involved aircraft, as dozens of Chinese MiGs fought against US-build Taiwanese F-86 Sabres.
Due to advantages in missile technology, the Taiwanese prevailed with something along the lines of a 15-1 kill ratio. By October the United States had sufficiently demonstrated its commitment to defending the islands that the PRC backed down. Taiwan and China settled into a desultory pattern of bombarding one another on alternate days of the week, a practice that continued into the 1970s.
