(2) On the side of the Qing army:

1. Be able to seize the opportunity and take advantage of the weak strength of the Taiping Army to quickly encircle Anqing and take the lead.

Taking advantage of the absence of the main force of the Taiping army on the Western Front, Zeng Guofan quickly mobilized 90,000 troops to surround Anqing, and there were only more than 20,000 people in the city at this time.

2. Skillfully use the rebels of the Taiping Army as the guide to capture the key points outside the city of Anqing and form a closed door

Dog power. In the winter of 1859, the Qing Dynasty sent Zeng Guofan, the leader of the Hunan army, to besiege Anqing in four ways. In May 1860, Yang Zaifu, the commander of the Qing army's naval division, led the naval division to storm Zongyang, an important town in the lower reaches of Anqing. The Taiping rebel general Wei Jun dug up the dikes of Luozhou and Xiashou near Zongyang and diverted water into Houhu, allowing the Qing army to advance by land and water. The Taiping army guards Lian Tianfu and Wan Zongsheng led their divisions to fight and died one after another. On June 20, Zongyang fell, and Anqing was in danger. Wei Jun suddenly smashed straight into Liantan, cutting off the grain route of the Taiping army's reinforcements, and the Taiping army's reinforcements were killed

Chased back to Tongcheng.

3. Taking advantage of the weakness of the various units of the Taiping Army to do their own thing, not fighting resolutely, and dividing troops to meet the battle, concentrate forces to break the Taiping Army reinforcements and completely cut off the foreign aid of the Anqing defenders. Focusing on the anti-guest, fighting steadily and steadily, biting the vital parts of the Taiping Heavenly Kingdom, focusing on positional warfare, pressing forward step by step, avoiding the Taiping Army's advantages of flexibility, impermanence, and quick victory, and giving full play to its advantages of strong strength and better equipment. In April 1861, Chen Yucheng's army returned from eastern Hubei and personally led 30,000 main forces to arrive inside and outside Jixian Pass on the 27th. On the 29th, Chen Yucheng and Anqing guard general Ye Yunlai respectively built 18 fortifications on the north and south banks of Linghu Lake in the northeast of the city, communicated internal and external contacts by boat, and sent Wu Dingcai, the chief general of Pingxi, to lead 5,000 troops into the city to help defend it. At the beginning of May, more than 20,000 troops including Ganwang Hong Renji and others who came to the aid from Tianjing were stationed in the vicinity of Xin'andu and Liantan, seeking to join forces with Chen Yucheng and relieve the siege of Anqing. Later, it was blocked by the Hunan army and retreated to Tongcheng. Huang Wenjin, the chief general of the Taiping Army in Dingnan, came to the aid from Wuhu Beidu, united with the Twist Army and Hong Renji and other armies, re-attacked the Qing army of Xin'andu and Trailer River, and was defeated by Duolong Abe and retreated to Tongcheng Kongcheng. At this time, more than 10,000 people from the Hunan army Bao Chao and Cheng Daji were transferred from southern Anhui and Hubei to help, with the purpose of besieging Chen Yucheng's troops in Jixian Pass. After Chen Yucheng learned about it, he withdrew from Jixian Pass, and left thousands of elite soldiers such as Liu Xuanlin, the owner of Jingjing, to continue to guard the four bases such as Chigangling, and brought five or six thousand people to Tongcheng on May 19, and agreed to divide the three-way army to Anqing, but the plan was to detect that when the three-way army attacked, it was ambushed by the Hunan army that was waiting for it, and the remnants of the army retreated to Tongcheng. The Hunan army took the opportunity to counterattack, Bao Chao began to attack Chigangling, Liu Xuanlin and others led the army to fight, and finally ran out of ammunition and food, Liu Xuanlin was captured in the breakthrough and died. Chigangling was lost, and thousands of elite Taiping troops were wiped out. In early July, the Hunan army captured all the strongholds on the periphery of Anqing and approached the city of Anqing, and Anqing was in danger. At the beginning of August, Chen Yu became the last effort to relieve the siege of Anqing, and convened a meeting of generals from all walks of life, and then organized a counteroffensive by men and horses from all walks of life. Then, he attacked the enemy's rear trench in ten ways, one after the other, bravely attacked, and once broke through the first layer of the enemy's camp. The Taiping soldiers each carried a bunch of thatch, rushed to the trench of the Qing army, and while cutting and killing, they filled the ditch with thatch. The Qing army resisted stubbornly and concentrated all its artillery fire on the Taiping army. The Taiping Army followed one after another. The corpses in the trenches were pressed one layer after another, mixed with the thatch, and the trenches were filled; However, the Qing army relied on the base to block the attack, and there were naval artillery, and the Taiping army's repeated attacks failed to work.
