1In July, 949, the Central Military Commission of the Communist Party of China (CPC), presided over by Mao Zedong, sent a strategic intention to the Third Field Army of the People's Liberation Army and the East China Military Region, namely, "In order to ensure coastal security, smash the invasion of enemy planes and ships on our mainland, and facilitate future attempts to seize Taiwan Province Province, the first goal is to seize Dinghai and destroy the enemy of Zhoushan Islands." According to the above-mentioned strategic intention, the East China Military Region established the East Zhejiang Front Command, and Ji Pengfei, commander of the ninth corps, deputy commander of the seventh corps and deputy political commissar of the seventh corps, mobilized the 22nd and 21st armies to undertake the task of liberating Zhoushan. On June 4th of the same year, President Mao Zedong approved the Dinghai Operation Plan reported by the East China Military Region. In the telegram drafted for the Central Military Commission, he pointed out: "We think it is correct for you to adopt a cautious attitude, concentrate superior forces, make full preparations in advance, and try to avoid being arrogant and underestimating the enemy." 10 days later, Mao Zedong sent a telegram to three leaders of the East China Military Region, Chen Yi, Su Yu and Rao Shushi: "There are 50,000 enemy troops in Zhoushan Islands, and their fighting capacity is quite strong. Haven't you two and a half armies attacked enough? In view of the defeat of Jinmen Island and an island near Dinghai, you must pay close attention to the strength, deployment, preparation and attack timing of Dinghai, if you are not well prepared. In view of the fact that the air and sea control were in the hands of the enemy at that time, the frontline command post analyzed the preparation of troops and ships and temporarily stopped attacking the enemy-occupied islands. 65438+ In February of the same year, Chairman Mao decided to transfer some troops from the newly established People's Navy to participate in the Zhoushan Campaign. Since then, Chairman Mao has made four telegrams (inquiries) on ship preparation, attack timing and enemy situation.

On February 6th, 1950, the Kuomintang air force entrenched in Zhoushan dispatched 17 sorties from Dinghai and Daishan airports to attack Shanghai, killing and injuring 1352 citizens and damaging Yangshupu power plant. Mao Zedong, who is visiting Moscow, is very concerned about this. Zhoushan and Shanghai are as close as lips and teeth, and the relationship is too important. The telegram about "first fight dinghai, then fight kinmen, and after the sea is conquered, send troops to Fujian to fight kinmen" was drawn up by Chairman Mao in Moscow. In the Sino-Soviet negotiations on air strikes against Shanghai, Chairman Mao also asked the Soviet Union for air support. Before and after, Chairman Mao repeatedly instructed to strengthen the construction of the People's Air Force. By the end of February of that year, Xuzhou, Nanjing, Hangzhou, Quzhou, Ningbo and other military airports in East China had been built and put into use. On the eve of the liberation of Zhoushan, the People's Air Force, which took off from airports such as Shanghai and Hangzhou, shot down six enemy planes and seized local air superiority over East China.

On May 1950 and 16, the command post in front of eastern Zhejiang ordered a full-scale attack: 2 1 Army marched from Dembu Island in the east, 23 Army marched from Damo Island in Zhonglu, and 22 Army marched from Cizi Island in the west. /kloc-in June of 0/7, the Third Route Army joined forces with Zhoushan Island. By 19, Daishan, Changtu, Qushan and Putuo Mountain were all liberated. However, because the PLA did not have the right to control the sea at that time, it failed to intercept, pursue and annihilate the fleeing enemy. After reading the good news of Zhoushan's liberation, President Mao Zedong sent a telegram on 18 to advise on the disposal of enemy facilities, and congratulated Zhoushan's liberation on 2 1 in the name of China People's Revolutionary Military Commission. The cable pointed out: "This victory broke the plan of the remaining bandits in Taiwan Province Province to block, bomb and harass East China based on Zhoushan Islands, and further created conditions for the liberation of Taiwan Province Province." The above-mentioned manuscript of Chairman Mao's command of Zhoushan Campaign has left precious materials for future generations to study this campaign.

The main force of Kuomintang troops entrenched in Shengsi Islands also withdrew in mid-May. On July 7 of the same year, the 98th Division of the People's Liberation Army Songhu Guard sent four battalions to capture Yangshan, Sijiao, Shengshan and Lycium Islands on the same day, and the remaining pirates on the islands either surrendered or were all annihilated. At this point, Zhoushan Islands were completely liberated. In the whole campaign, more than 8,900 Kuomintang troops were annihilated, 83 guns of various types were sunk, 3,209 guns (cannons), 6 radio stations 10, 22 cars and 0 ships10. Nearly 2,000 people, including China People's Liberation Army combat hero and Luoyang battalion commander Lin, died.
