In 1938, the Battle of Wuhan was fierce, the Kuomintang dispatched troops from various theaters to block the Japanese army in Anhui, Henan, Jiangsu, Hubei and other places to protect the Wuhan National Government, in order to maximize the containment of the Japanese army, the Kuomintang Third Theater ordered the New Fourth Army to advance into southern Jiangsu (mainly the second detachment of the New Fourth Army led by Su Yu, su Yu as deputy commander) to cooperate with the frontal battlefield to contain the Japanese army from Jiangsu to Wuhan.
Su Yu lived up to the expectations of the people and successively led his troops to sabotage the Japanese railway transportation in Dangtu, Wuhu and other places, and the Japanese army never expected that the New Fourth Army, which had entered southern Jiangsu for less than half a year, would soon have such a great destructive power, so it had to put away its contempt.
In August, the Japanese army launched a retaliatory encirclement and suppression, and the Japanese Central China dispatch army stationed in Nanjing drew 4,000 people, 500 cavalry, and divided the troops into eight roads to encircle and suppress the Xiaodanyang base area of the New Fourth Army (where Su Yu's second detachment was stationed).
Su Yu decided to use the strategy of "the enemy advancing and we are advancing", these four words are related to Chairman Mao
"The enemy advances and retreats, the enemy stays in me to disturb, the enemy is tired and I fight, and the enemy retreats and I chase"
As early as three years ago, during the guerrilla war in southern Zhejiang, Su Yu tried and failed repeatedly, and his main policy was not to strike head-on with the enemy, but to jump out of the enemy's encirclement, that is, the so-called battle jump from the inner line to the outer line, and then concentrate the main forces to annihilate the enemy all the way, turning passivity into initiative.
Can the four words "the enemy enter and I advance" still create miracles? Faced with several times the enemy's own strength, Su Yu ordered the first detachment of the two detachments to attack Dangtu in order to attract the Japanese troops to encircle and suppress the troops, and at the same time ordered the main force to disperse and conceal the breakthrough from the gap between the enemy troops, and sent a group of elite troops to assemble and attack Tao Wu and Yuhuatai south of Nanjing; at the same time, in order to cooperate with the two detachments in counter-encirclement and suppression, a detachment led by Chen Yi mobilized the vast number of local armed forces and the masses of the people to destroy the main communication arteries around Nanjing, such as Beijing-Shanghai, Beijing-Hangzhou, Zhenju, and Judan, in order to delay the reinforcement of the Japanese army; in order to increase the pressure on the Nanjing garrison, Chen Yi also ordered the armed engineering teams in the base areas to attack the major gates of Nanjing at the same time, and for a while the emergency telephone of the Japanese headquarters in Nanjing rang non-stop.
Just when the Japanese encirclement and suppression troops arrived in Xiaodanyang, not only did they not find the main force of the New Fourth Army, but also received an urgent telegram from the Nanjing side, informing them not to look for it, the flag of the New Fourth Army had been planted on the commanding heights of Yuhuatai, and the New Fourth Army was everywhere around Nanjing City; the Japanese encirclement and suppression troops quickly turned around to help, which was exactly the result of Su Yuyao, the various units of the New Fourth Army quickly gathered to bite the Japanese army to death, and when the Japanese army returned to Nanjing City, the attacking troops had long since withdrawn, and the nanjing city had returned to calm, and more than 50 Japanese troops were killed in this battle. Successfully smashed the Japanese encirclement and suppression plan.
This battle fully proves that the guerrilla thinking of "the enemy is advancing and we are advancing" summed up by Su Yu in practice is also applicable to the battlefield behind the enemy lines of the Anti-Japanese War; the Japanese army, which is accustomed to fighting regular warfare, cannot understand Su Yu's strategic intentions at all, and the fist that has been hard to clench up is empty with all its might, and when you retreat, the New Fourth Army suddenly all of them will suddenly appear to hit you, and even if it is armed with advanced weapons and equipment, it is difficult to organize an effective counterattack.
