The classic battle of the war of liberation:

I. Battle of the Soviet Union (Commander: Su Yu)

After the war of liberation broke out in an all-round way, the Kuomintang troops concentrated their forces to invade the liberated areas in central Jiangsu. Under the command of Su Yu, the Central China Field Army adopted the operational policy of relying on the interior lines of the Soviet liberated areas to wipe out the enemy, used 55,000 People's Liberation Army to deal with 1.2 million Kuomintang troops, and adopted flexible tactics to win seven battles.

More than 53,000 Kuomintang troops were wiped out, and all kinds of guns 160 were seized, which won the battle of the Soviet Union and set up a model for the PLA to rely on insiders. It can be called a surprise soldier in the history of war. The Central Military Commission called the campaign a "great victory" and "hoped that all regions would follow suit".

2. Battle of Meng Lianggu (Commander: Su Yu)

After the plan of all-round attack on Shandong liberated areas failed, the Kuomintang army launched a key attack on Shandong liberated areas. Under the command of Su Yu, the East China Field Army fought the invasion of 450,000 Kuomintang troops with 200,000 People's Liberation Army. First, it found the soldiers by luring the enemy in depth, and then with the courage and courage of "a million troops take the head of the general", it concentrated its superior forces to cut off the attack of the main body of the enemy.

In Meng Lianggu, the 74th Division of the reorganization of the Kuomintang Army was annihilated, 38,000 Kuomintang troops were annihilated, and 267 guns of various kinds were seized, which set a precedent for the People's Liberation Army to cut off the main offensive force from the center of the enemy front when the enemy's heavily armed groups went hand in hand intensively. At the same time, it initiated the People's Liberation Army to annihilate the five main forces of Chiang Kai-shek Group, and initially smashed the key attack of Kuomintang troops on Shandong liberated areas.

Three. Southwest Shandong Campaign (Commander in Chief: Liu Bocheng)

Southwest Shandong is the key point for Liu Dengjun, the field army of the Central Plains, to cross the Yellow River to carry out strategic attack. According to the Central Committee of the Communist Party of China's instructions, Liu Dengjun, the field army of the Central Plains, crossed the Yellow River to advance to the southwest of Shandong Province, which started the strategic offensive of the People's Liberation Army. In this campaign, in order to prevent Liu Deng's troops from going south and ensure the safety of Longhai Road, the Kuomintang mobilized troops to attack Liu Deng's troops crossing the Yellow River in the south.

Liu Bocheng commanded 120000 The People's Liberation Army faced the invasion of 180000 Kuomintang troops, calmly assessed the situation, firmly grasped the weakness of coming to help the enemy, concentrated its forces one by one to annihilate the enemy, annihilated more than 60,000 Kuomintang troops, and seized 872 guns of all kinds, thus winning the battle in southwest Shandong and effectively cooperating with the key attack of crushing the enemy by the East China Field Army.
