The Huaihai Campaign entered the second stage, and the seven columns of the Central Plains Field Army attacked in an all-round way, encircling more than 100,000 regiments of 12 corps led by Huang Wei in a narrow area centered on shuangduiji in the southwest of Suxian County, with a vertical and horizontal area of only 7.5 kilometers. After being surrounded, Huang Wei commanded the troops to break through desperately. In the process of breaking through, Liao Yunzhou, commander of the 110th Division, led the troops to revolt, dealing a heavy blow to the 12th Corps.
Although the 110th Division's uprising dealt a heavy blow to the 12th Corps, Nakano could not fight due to the lack of heavy weapons, and there was a possibility of being broken through by the Huang Wei Corps. In order to support nakano's operations, two columns of Huaye also came with heavy weapons to attack Huang Wei's corps. The Battle of Shuangduiji was not easy to fight, because this corps was all a member of the Nationalist army, and the 18th Army, one of the five main forces, was also in this unit, and the combat effectiveness of this unit was very strong. In the final stages of the Battle of Shuangduiji, the two sides engaged in a fierce battle at Dawangzhuang.
Dawangzhuang was a barrier to the south of the core position of the Huang Wei Corps, and this place was only a few kilometers away from the headquarters of the 12th Corps, so Huang Wei and Hu Lian placed the 33rd Regiment of the 118th Division of the 18th Army, which they trusted most. The 33rd Regiment of the 118th Division is known as the Tiger Regiment, and this unit has more than 3,000 people in the regiment, all of whom are composed of veterans, with excellent weapons and strong combat effectiveness. After the 33rd Regiment entered Dawangzhuang, it began to build fortifications day and night, building a large number of bunkers, scattered pits, traffic trenches, and dismantling all the wood in the whole village to build fortifications, in order to clear the obstacles for the machine guns, and also cleared all the nearby obstacles.
The first to attack Dawangzhuang was the Seventh Column of Huaye, and after receiving the order, the 20th Division of the Seventh Column immediately carried out half an hour of artillery preparations for Dawangzhuang, and after the artillery preparations were completed, the 58th Regiment and the 60th Regiment launched a strong attack on Dawangzhuang from the south. At that time, the People's Liberation Army was very strong, and the forward troops drove the 33rd Regiment out of Zhuangnei in one turn, Hu Lian heard that Dawangzhuang was lost, and immediately ordered all the artillery of the 18th Army to shell Dawangzhuang, and the commander of the 33rd Regiment led the troops to launch a dozen consecutive attacks on Zhuangnei. The two sides fought one house after another, and in the end, only the 59th Regiment of the 20th Division of the Seventh Column remained in the southwest corner of the Village, and the 58th regiment and the 60th Regiment had to withdraw for rest due to too many casualties.
At a critical moment in the battle, the 46th Regiment of the 6th Column of Nakano rushed to the aid, and this regiment quickly contacted the 60th Regiment of the 7th Column of Nakano and joined forces to launch a large-scale counterattack against Shonai. The sound of grenades, explosive packs, mortar shells exploding on both sides never stopped. The 33rd Regiment finally sent the servicemen, the men, and the car soldiers, and finally the Seventh Column Command took the guard company up, which completely annihilated the Tiger Regiment and took the Great King Zhuang. After the end of the Battle of Dawangzhuang, the 12th Corps Headquarters was exposed to the attack range of the PLA units, and Huaye and Nakano moved quickly to attack the 12th Corps Headquarters. At the Time of the Battle of Dawangzhuang, a main regiment of the 85th Army was stationed in Xiaowangzhuang, which surrendered to the Seventh Column of Huaye after watching the battle.
