At the end of September 1946, the Kuomintang army achieved a series of victories in the northeast region, especially the offensive commanded by Du Yuming and Zheng Dongguo, which was initially successful. At that time, the liberation of Northeast China was divided into two parts, Northern Manchuria and Southern Manchuria, and Southern Manchuria became the focus of liberation.
However, in October 1946, the Kuomintang army mobilized the elite forces of nine divisions to launch a fierce offensive against the Liberated Areas of Southern Manchuria. Unfortunately, the Liberated Areas of Southern Manchuria adopted a defensive strategy, a strategic mistake that led to a large number of casualties and loss of land. The Kuomintang troops captured 17 county towns in a row, rapidly reducing the territory of the Southern Manchuria Liberated Area to only 5 counties.
The situation was critical, and Southern Manchuria was in an unprecedented predicament. The leaders of the Liberated Areas of Southern Manchuria began to disagree, and some even refused to obey Lin Biao's orders. Lin Biao felt the crisis, so he took decisive action to change the leadership of Southern Manchuria and appointed Chen Yun and Xiao Jinguang to leadership positions.
At the Qidaojiang Conference, Chen Yun resolutely advocated defending the Liberated Areas of Southern Manchuria and resolutely refusing to back down. This decision changed the course of the war in the northeast. Lin Biao used the ingenious angle to form a strategy of fighting on the two fronts of Northern Manchuria and Southern Manchuria. This strategy put unprecedented pressure on the Kuomintang troops, as they had to divide their forces against the attacks of the Southern Manchuria Liberated Areas and Lin Biao.
Under Lin Biao's command, his subordinate Han Xianchu scored a series of important victories in western Liaoning, leaving the Kuomintang army in a difficult situation and fighting a battle. The Kuomintang was forced to mobilize more troops to deal with the attack of the Liberated Areas of Southern Manchuria and Lin Biao, but Southern Manchuria resolutely held its position and did not back down.
In the end, in the "One Protection Linjiang, One Jiangnan" campaign from the end of 1946 to the beginning of 1947, the Southern Manchuria Liberated Area successfully thwarted the attack of the Kuomintang troops. This victory not only brought confidence to the Liberated Areas of Southern Manchuria, but also brought the dawn of the entire Northeast Liberation War and passed the darkest hour.
This period of history vividly demonstrates Lin Biao's military talent and tenacity, as well as the persistence and wisdom of the Chinese Communist Party in the face of difficulties. This victory also laid the foundation for subsequent victories, proving the invincibility of the Chinese Communist Party on the road to liberating Northeast China.
