In the siege of Changchun and the uprising of the 60th Army and the surrender of the New 7th Army, our army annihilated 95,855 enemies. In September 1948, the main force of the Northeast Field Army went south to fight along the Beining Railway. With the adjustment of the overall deployment of the Liaoshen War Project, the 12th Column was transferred southward, and the independent 1st, 3rd, 4th, 12th, and 13th Divisions were added to the Changchun direction. Together with the 2nd Inner Mongolia Cavalry Division and 14 independent regiments, together with the original troops, 160,000 people participated in the siege, and the company camped for hundreds of miles, forming a tight siege and blockade.
The Changchun defenders were shaken by hunger, their morale was disorganized, war-weariness, and the phenomena of desertion and surrender were increasing day by day. By mid-October, the siege troops completely destroyed 18,000 defenders and annihilated more than 4,300 defenders who tried to break out. On October 15, after the main force of the Northeast Field Army captured Jinzhou, President Chiang Kai-shek of the Kuomintang government sent a plane to Changchun to deliver an airdrop order, strictly ordering Zheng Dongguo to lead his troops to break out of the encirclement and withdraw to the south.
The 1st Corps of the Northeast Field Army took advantage of the factional struggles within the defenders to step up their work. On the night of the 16th, Zeng Zesheng, commander of the 60th Army of the garrison, sent people out of the city to discuss the uprising with the 1st Corps of the Northeast Field Army. On the 17th, Gan led the military headquarters, the 183rd Division and the temporary 21st and 52nd Divisions to revolt with more than 26,000 people. That night, the Independent 6th and 8th Divisions of the Northeast Field Army quietly took over the 60th Army Defense Area in the eastern half of Changchun.
On the 19th, Li Hong, commander of the newly formed 7th Army of the garrison, led the military headquarters, the new 38th Division and the temporary 56th and 61st Divisions to surrender. Changchun was liberated. On the morning of the 21st, Zheng Dongguo led the 1st Corps headquarters to also lay down their weapons. Extended information
After the "September 18th Incident", Japan gathered a group of domestic first-class experts and adopted European and American construction theories to carry out planning and design in Changchun. The greening system not only absorbs Howard's garden city theory, but also pays attention to the overall environment.
The new area adopts a diversion drainage system to keep the water in the park green space clean, and uses natural ditches to create green belts that rely on the terrain. Electricity, telecommunications, and lighting lines will be made underground on major arterial roads, and power line corridors will be set up in new residential areas. In order to adapt to the urban transportation mode in the 1930s, planar roundabouts were adopted and many circular squares were designed.
