In September 1944, Peng Xuefeng was killed by a stray bullet while leading his troops to besiege the Li Guangming detachment of the Balizhuang recalcitrant army in Xiayi County. In mid-October, when Wang Yuwen, a diehard Kuomintang faction and commander of the Provisional First Army, heard the news of Peng Xuefeng's death, he thought that he had an opportunity to take advantage of it, and hastily led his cavalry Eighth Division, provisional Fourteenth Division, Provisional Thirtyth Division, and about 40,000 local troops to the Fourth Division of the New Fourth Army in two routes. Zhang Aiping, the main leader of the Fourth Division of the New Fourth Army, and other cadres at or above the group level decided to eat the enemy who attacked on the north road first, and then eliminate Wang Yuwen.
The enemy of the North Road was the Kuomintang diehard Yang Kunshan and Hu Sairu's "Sulu-Anhui Advance Army", and Before the War of Resistance, Yang Kunshan was a famous bandit in the area of Yanshan. Under the leadership of Deputy Division Commander Wei Guoqing, the Ninth Brigade of the Fourth Division of the New Fourth Army and the Cavalry Regiment of the Division, after a three-hour rapid march, quietly arrived at the yang kunshan garrison, the Twenty-sixth Regiment of the New Fourth Army set up a pocket array in the north, the cavalry regiment pursued from the north to the south, and the Twenty-fifth Regiment advanced from south to west. In the middle of the night, the enemy was sleeping heavily, and suddenly the gun was loud, and he grabbed the gun and ran south. After the enemy ran in a panic in the darkness for three hours, it was already dark, and many enemy smokers had also come up, all of them were gray and pale, their whole bodies were scattered, and some of them were lying on the fields, but they did not expect that they had completely entered the "pockets" of the New Fourth Army. Therefore, the New Fourth Army effortlessly captured all of Yang Kunshan's troops.
Wang Yuwen, the commander of the enemy army on the south road, heard the news that Yang Kunshan's troops had been annihilated, and hurriedly commanded his troops to cross the Vortex River and attack The Mountain. When his vanguard attacked the positions of the 11th Brigade at Mount Mangzhong and Bao'an Mountain, he was intercepted by the New Fourth Army, which had long been ambushed here. During the battle, a battalion of the New Fourth Army sneaked into the rear of the enemy army and directly inserted itself into Wang Yuwen's headquarters. After an hour of fierce fighting, Wang Yuwen's army was annihilated, and Wang Yuwen panicked, disguised himself as an ordinary soldier, and left his troops to abscond. After the army headquarters was destroyed, more than 20,000 people in the three divisions of the enemy army were like headless flies, running around.
The New Fourth Army took advantage of the victory to pursue, and at dusk, it found a battalion of the enemy's Fourteenth Division hiding by a pond west of Yongcheng resting. When the Nineteenth Regiment of the Seventh Brigade of the New Fourth Army arrived there, the commander of the enemy battalion did not expect the New Fourth Army to advance so quickly, and thought that it was his own people, and casually asked: "Which unit are you from?" The soldiers of the New Fourth Army replied, "Hu Tian Brigade!" Before the words could be heard, the commander of the enemy battalion knelt on the ground and begged for forgiveness: "The New Fourth Army spares its life, brothers, quickly lay down your weapons, we have encountered the Hutian Brigade!"
The Hutian Brigade was the Nineteenth Regiment of the Seventh Brigade of the New Fourth Army. In 1939, the Eighth Route Army went south and sent a brigade to Huaibei, and under the leadership of captain Hu Bingyun and political commissar Tian Weiyang, they fought three hard battles in the Area of Sihong and Yanghe, eliminating more than 1,000 Japanese and Pseudo-Japanese, and the enemy suffered heavy losses, and they were very afraid of this team. Later, the Hutian brigade was stationed in Yanghe Town for three years, and the Japanese puppet army never dared to step into Yanghe Town for half a step. For this reason, the soldiers and civilians in the anti-Japanese base areas also changed their tongues to satirize the enemy: "The sky is not afraid, the earth is not afraid; I was afraid of the New Fourth Army's Boss Hu, and Boss Hu moved from end to end. ”
In order not to let the Eighth Cavalry Division slip through the net, Zhou Chunlin, commander of the Cavalry Regiment of the New Fourth Army, led the troops to pursue them non-stop, chasing for 200 miles in one go, and catching up with the Recalcitrant Eighth Cavalry Division at the junction of Yongcheng and Woyang. Zhou Chunlin ordered the troops to set up the Eighty-Two Pursuit Artillery on horseback, bombarding the enemy, and then slashing and slashing, completely annihilating the Eighth Cavalry Division of the recalcitrant army. At the same time, the enemy's provisional fourteenth division and provisional thirty division were surrounded and annihilated by the seventh, ninth, and eleventh brigades of the New Fourth Army in the Yuyang area.
The campaign began on October 14 and ended on October 25, the New Fourth Army annihilated more than 15,000 Kuomintang diehard troops, captured 1 mountain artillery, 1 mortar, 44 grenadiers, 19 heavy machine guns, 63 light machine guns, 852 rifles, and 49 short guns; The New Fourth Army lost 4 casualties and wounded 225. After the end of the War of Counterattack in the North of the Vortex, the New Fourth Army controlled a vast area stretching from Jinpu Road in the east, to the Shanghao Highway in the west, to longhai Road in the north, and to the Vortex River in the south, liberating a population of 2.5 million, establishing an anti-Japanese democratic government in 8 counties, and basically restoring the Yuwan-Suzhou base area three years ago.
