In December of the first year of Tongzhi (1862), the Qing court dismissed the command of Shengbao, the commander-in-chief of the Gan-Shaanxi battlefield, and took Duolong'a, a famous general of the Eight Banners from the Hunan Army, as the minister of the Qincha to supervise the military affairs of Shaanxi, and was fully responsible for the Gan-Shaanxi war. In order to unify the command, the Qing court specially issued an edict to transfer the sergeants of the Shengbao Department to the command of Duolonga, and General Duolonga became the supreme commander of the Qing army on the Ganshan battlefield.
Duolonga carefully analyzed the situation on the battlefield in Gansu and Shaanxi, as well as the distribution characteristics of the rebels, and formulated a steady and steady tactic. In January of the second year of Tongzhi (1863), Duolonga defeated the rebels in Tongzhou, beheaded more than 1,000 ranks, and the siege of Tongzhou was lifted. Then, Duolonga led the Daur cavalry, Jilin cavalry, Suolun cavalry, Heilongjiang Three Banners Horse Team, Shengjing Eight Banners Horse Team and other elite Qing army to attack Qiangbai Town, the rebel lair south of Luoshui. Qiangbai Town is the largest rebel stronghold in the Guanzhong region, and the defender of Qiangbai Town is also the most fierce and cunning Bai Yanhu of the Ganshan rebels, and Bai Yanhu has built a tight fortification in Qiangbai Town:
The walled fort wall stands thousands of feet, the antler dolphin fence, the dense row is several heavy, the surrounding is surrounded by thorns, and the fort police tower is high and cloudy.
There are more than 20,000 rebels in Qiangbai Town, all of whom are veterans of battle, and their combat effectiveness is comparable to that of ordinary rebels. Obviously, this is a difficult bone to gnaw, and Duolonga commanded the Qing army to attack, but it was all in vain. After a long time, Bai Yanhu also had a contempt, Duolonga grasped Bai Yanhu's psychological characteristics, pretended to be defeated, Bai Yanhu has been "abused" by Duolonga, thinking of finding some face to come back. So, Bai Yanhu led the army out of Qiangbai Town to pursue Duolonga, Duolonga saw the rebels out of the village, so he commanded the Qing army to turn the gun, counterattack the rebels, and immediately killed more than 2,000 rebels, Bai Yanhu led the remnants to flee into Qiangbai Town.
On the first day of the first month of February, when the rebels were newly defeated and their morale was low, Duolonga led the Qing army from all walks of life to launch a general attack on Qiangbai Town. At the critical moment, the logistics troops of the Qing army transported the newly imported Armstarang cannon, which was extremely powerful and a sharp weapon for attacking fortifications. With the roar of the Armstarang cannon, the fortifications built by the rebels were quickly destroyed, and the Qing army rushed into Qiangbai Town along the impact point of the Armstarang cannon, and the rebels quickly collapsed, and the Qing army successfully captured Qiangbai Town. Because the Qing army paid a heavy price in the battle of Qiangbai Town, the Qing army then executed all the rebels in the town to comfort the souls of their fallen comrades.
"All the rebels in the fort were slaughtered" - (Chen Kangqi. "Lang Qian's Chronicles")
After the Qing army captured Qiangbai Town, Bai Yanhu still led more than 10,000 remnants to retreat to the nearby Wangge Village. In line with the principle of eliminating all evil, Duolong Ah ordered all units of the Qing army to attack Wangge Village. The rebels were afraid of the strong combat effectiveness of the Qing army, and they did not dare to fight, so Duolong Ah calmly commanded the Qing army to break the rebel strongholds in Wangge Village, and more than 10,000 rebels in Wangge Village were wiped out, and the only regret was that Bai Yanhu "slipped away" in advance. After the Qing army entered Wangge Village, they rescued more than 10,000 Han women and children who were imprisoned. When Dorona saw the remains of a large number of civilians who had been executed by the rebels, the fierce Dorona ordered the beheading of all the more than 1,000 rebels who had surrendered, regardless of battlefield discipline.
The Battle of Qiangbai Town was the first major victory since Duolong'a entered Shaanxi, which annihilated more than 20,000 elite rebels and wiped out the largest rebel nest in Guanzhong in one fell swoop. Then, relying on the aftermath of the Battle of Qiangbaizhen, Dolonga launched a larger-scale attack on the rebels, who fearfully called Dolonga "Grandpa Duo".
