1949 In May, the Second Field Army of the Chinese People's Liberation Army 19 Army was established under the order of the Central Plains Front Committee. On May 8, the 19 Army received a telegram from the Central Military Commission: "The First Field Army began to seize Tongguan, Xi and Baoji in June. It is best to take Hanzhong directly and cut off Hu Zongnan's retreat to northern Sichuan. I received a telegram from Liu and Deng, the heads of the Second Field Army, saying, "On May 8, with the strength of the Central Committee, we made active preparations. "12 July, the 55th division of 19 Army moved westward from Nuwa Mountain area to Ankang, with the 55th division of 65433. Niu Dahua Brick is located in the southeast of the outer city of Ankang City, and it is named because it looks like a cow's hoof. It faces Daba Mountain in the south and the surging Han River in the north. The terrain is dangerous, easy to defend but difficult to attack. Han (Central) Bai (River) Highway leads to Ankang from Jiaoling, which is the gate outside Ankang. Niutiling is blocked, and Ankang is difficult to keep. So the three forces defending Ankang are all fortified here. On 24th 1 hour, 1 63rd regiment 1 battalion engaged in fierce fighting1hour, and captured the main position of Niutuling. By 0400 hours, the enemy was repelled five times in a row. Because of heavy casualties, it was replaced by the third battalion, and the position changed hands several times. After dawn, more than half of the 3rd Battalion was killed and wounded, and they withdrew from the battle. At the same time, the 55th Division164th Regiment, after seizing Shitou Village in Daniuling, took three hills to the north and was killed by the enemy's main position and flank fire. Meng, deputy head of the regiment, died in the battle. The whole Niutiling battlefield was full of gunfire, the smoke covered the sky, the killing was deafening, the blood was dripping, and the fighting was unprecedented cruel. My face-to-face enemy is the New Third Army, the main force of Hu Zongnan, and the automatic artillery regiment. In order to ensure the Qinling defense line, the enemy dispatched 1 10 troops from Sichuan to reinforce. After 10 hours of bloody fighting, the position is still being repeatedly sawed. At 1 pm, the 2nd Battalion of 163 Regiment, under the personal command of Colonel Niu Yuchuan, courageously attacked and retaken all the positions of Niutuiling in one fell swoop, and the regimental headquarters was located on the ridge. The enemy retaliated crazily. 100 guns were concentrated in Niutuiling, and the enemy of the whole battalion stormed the mountain under the threat of the overseers. 163 regiment beat off the enemy's group charge five times in a row until 6 or 7 o'clock in the afternoon. 169 The 3rd Battalion was reinforced by its head Dong Mingrui, and finally defeated the enemy. 164 regiment stabilized the position of Shitouzhai with the reinforcements of 17 1 2nd battalion. After dark, the 57th Division 164 Regiment and 169 Regiment launched an attack on the enemy, driving the enemy to the north bank of the Han River in one breath and occupying Ankang New Town. In order to keep the enemy stranded in southern Shaanxi, prevent Hu Zongnan's troops from shrinking prematurely in the direction of Sichuan and Yunnan, and ensure that the main force of the Second Field Army detoured to the southwest, closing the door and beating dogs. Before dawn on the 25th, the troops withdrew from Ankang, returned to Pingli and transferred to training and consolidation. The battle in Niutiling is very fierce and cruel. In this campaign, the 55th Division * * * annihilated more than 2,550 people from the 69th Army, the 27th Army and the New 3rd Army, with casualties of 1250 people. Although he sacrificed a lot, he cooperated strategically with our main force in the northwest battlefield and retreated to the southwest, which not only dealt a heavy blow to the fourth enemy army, but also realized the strategic intention of the Central Military Commission to contain and contain Hu Zongnan Group in the Qinling area with 18 Corps and 19 Corps.
