On May 1949 and 12, the troops of Sanye launched an attack on the defenders outside Shanghai. By 14, the Ninth Corps had captured Pinghu, jinshanwei, Fengxian, Nanhui, Songjiang and Qingpu, and advanced towards Chuansha, threatening the defenders. Tang was forced to deploy the 5 1 Army from the urban area to Bailong Port and Linjia Wharf to strengthen the defense. 10 Corps captured Kunshan, Taicang, Jiading, Liuhe and other places, and continued to storm the defenders of Yuepu, Yang Xing and Liu Xing. Relying on reinforced concrete bunkers, supported by naval guns and planes, the Kuomintang troops carried out continuous counterattacks. In June, 5438+05, the 2 1 Army and the 99th Division moved from the urban area to Yuepu, Yang Xing and Liu Xing to strengthen their defense and blocked the attacking troops.
Accordingly, the General Front Committee pointed out: Don't be impatient, take the initiative and make full preparations to conquer reinforced concrete fortifications. Sanye headquarters immediately issued tactical instructions, summed up the experience of attacking reinforced concrete bunkers and adjusted the deployment. Instead, small teams were the main actions, and the attack tactics of combining firepower, blasting and assault were implemented to seize the bunkers one by one, which accelerated the fighting process.
To 19 and 10, the Corps successively captured Yuepu and International Radio Station, and wiped out the defenders in Liuxing area. The 9th Corps captured Chuansha and Zhou Pu, annihilated the 5 1 Army in Bailonggang, compressed the Gao Qiao 12 Army, and cut off its contact with the 37th Army in Pudong, resulting in the situation that the 10 Corps attacked Wusongkou. In order to maintain the sea passage at Wusongkou, Tang Bowen moved the 75th Army to the east to increase the defense against Gao Qiao. Relying on the favorable conditions of the border area between the river and the sea, surrounded by water on three sides and narrow terrain, with the cooperation of the navy and air force, they frequently counterattack. The attacking troops fought fiercely with them. ?
On 23rd, long-range artillery of special forces column shelled Kuomintang warships on the northeast coast of Gao Qiao, hitting 7 ships, and the rest fled. At this point, the sea area east of Gao Qiao was blocked, and the main defenders were compressed in the areas on both sides of Wusongkou, which created favorable conditions for seizing the urban area and adowa the defenders. After 10 days of peripheral operations, the People's Liberation Army annihilated more than 20,000 Kuomintang troops and captured the peripheral positions and some major positions of the defenders. However, it takes a long time to carry out surprise attacks only from the two wings, and the geographical area is narrow, which is not convenient for troops to deploy. It takes a long time to attack every point, and it is difficult to work in a short time, but defenders can concentrate on sticking to it.
In view of the preliminary completion of the preparatory work for the East China Bureau to take over Shanghai, the Central Military Commission of the Communist Party of China (CPC) approved the proposal that Sanye first capture the urban area and then solve Wusong. The General Front Committee also instructed to attack the city from south to north at the same time to disperse the defenders. In order to strengthen the attack on the urban areas, the Third Field Army added all the artillery of the 23rd Army of the 7th Corps, the 25th Army of the 8th Corps and the special forces column, and placed them under the 9th Corps and 10 Corps respectively.
On the night of May 23rd, the first 29 army captured the highland in the southern suburbs of Yuepu, and the 28th Army approached Wusong, shelling Wusong Wharf. On the 24th, the 20th Army captured Pudong, and the 27th Army occupied Hongqiao and Xujiahui Station. At this time, Tang and his headquarters, who had boarded the 18 ship to escape, saw that the general trend was gone, and at the same time transferred the 6th Division of the 75th Army from Gao Qiao to Yuepu to strengthen the defense and ensure the safety of Wusong. At the same time, he commanded the main force north of Suzhou Creek to shrink to Wusong, ready to flee from the sea.
The headquarters of the Third Field Army immediately ordered all troops to pursue, boldly go deep into the depth of the defenders, and intercept and annihilate the fleeing enemies respectively. It was a day and a night. The 23rd Army and 27th Army entered the city from Xujiahui and Longhua respectively, and the 20th Army main force crossed the Huangpu River from Gaochang Temple to the west. All the troops jumped forward quickly, intrepidly surrounded by detours, went straight into every street, and seized the fire of barricades and buildings. By dawn on the 25th, they all controlled the city south of Suzhou River. Subsequently, the whole line continued to storm, and the 26th Army of 10 Corps captured Dachang and Jiangwan, and 29 army captured Wusong and Baoshan on 25th and 25th, while the 28th and 33rd Army captured Yang Xing and other places, and the 27th, 23rd and 20th Army of the 9th Corps crossed the Suzhou River by night and quickly occupied the urban area of Hebei. The defenders were wiped out one by one. At this time, Liu Changyi, the deputy commander of Shanghai and Shanghai garrison, who was in charge of commanding the remnants of the Kuomintang army in Shanghai, led his troops to surrender under the strong military pressure and political offensive of the People's Liberation Army.
On the night of 25th, 3 1 Army, with the cooperation of 30 troops, fought bloody battles to conquer Gao Qiao. By noon on 26th, the remnants of the defenders in Pudong area were destroyed.
On the 27th, Shanghai was completely liberated. Subsequently, the 25th Army launched an attack on Chongming Island, destroying the defenders 1 people and liberating the whole island on June 2nd. At this point, the battle of Shanghai ended successfully.
