The Second Taiwan Strait Crisis (the Taiwan Strait Crisis of 1958) was lasted for two months or so, was proved that Mao Zedong's intention to invade Kinmen was in the nature of test rather than a strong determination. It can be divided into four stages. First, it was ignited by the time PRC (People's Republic of China) started bombing, in a large scale, Kinmen on August 23. And on September 4 in that year, then U.S. Secretary of State, John F. Dulles issued a declaration on the situation across the Taiwan Strait. Second, on September 6, PRC made a positive gesture toward holding a talk with U.S. And then on September 15, two parties formally held the first round of talks in Warsaw. Third, after September 16, escorted by U.S. fleets, ROC's (Republic of China) naval supply ships could do their duty so smoothly that halted PRC's intention of blockading and even cutting Kimen's supply lines. On October 6, PRC declared, with a free hand, that it will stop bombing Kinmen for a week. Fourth, after October 7, PRC prolonged the suspense of its bombing and then on October 23, John F. Dulles finished his visit to Taiwan, ROC and U.S. issued a joint communiqué, in which ROC promised that ui1ess upheavals arose in PRC, ROC will not use force to recover mainlanders' freedom. Instead, it would achieve the goal through means of politics. From then on, the peaceful situation across the Taiwan Strait has been maintained for around fifty years.
