1, attack Chen Cang
In May of the first year of Han Dynasty (206 BC), in order to successfully seize Chen Cang, Hanwang took Cao Can's decision in advance, followed the old road, went out of the customs and went straight to Chen Cang.
Hanwang Liu Bang then led tens of thousands of Han troops from Nanzheng, where Hanzhong was stationed, crossed the Qinling Mountains through the old road and attacked Zhang Han, Wang Yong from the old road. At this time, Yong Wang Zhang Han led the army to stick to Chencang, with the intention of blocking the Han army in Chencang. When it was difficult for the Han army to capture Chencang, Zhao Yan provided Hanwang with a mountain road to bypass Chencang's front, and Liu Bang sent the Han army across the mountain road to bypass Chencang's front and raided Chencang from behind, and then the Han army was defeated in Chencang's attack.
Liu Bang sent Fan Kuai to defeat Xicheng Xiancheng's army in the north of Baishui, and defeated Wang Zhanghan in the south of Yongxian. Cao Can led the army to capture Yongcheng in the north. Zhang Han retreated to goodness _ and Hanwang fought and suffered a crushing defeat. He retreated to the abandoned mountain, and his brother Zhang Shou was about forty miles north of Shanxi, and the two armies fought. Liu bang led the Han army to surround the barren hills and rivers.
2. Take Xianyang
Liu Bang sent the Han army eastward to Xianyang, and sent Cao Can to capture _ County. Then Cao Shen attacked Zhangping in the north and defeated Zhangping in the south. So he sent frequency and Fan Kuai to conquer Li Huai, and then frequency, Cao Can, Fan Kuai and others attacked the city together. Zhou Bo and Fan Kuai surrounded Zhang Ping in Hao _; Cao Can went south to borrow soil alone, breaking the three Qin Jun and tall oak trees in Tudong; After that, Cao Can, Zhou Bo and Fan Kuai attacked Zhangping, which was surrounded by Hao, attacked Hao, and Zhangping fled.
The Han army occupied _ and opened the gate of Xianyang. Next, Cao Can led the troops to attack Xianyang with frequency and Fan Kuai, and fought fiercely with the troops of He Neibao near Xianyang, defeated them and conquered Xianyang, the capital of Qin State.
3. Shimonoseki Valley Pass
After the Han army captured Xianyang, Liu Bang first captured Hangu Pass and isolated the connection between Sanqin and Kanto. Sima Xin, the King of Sai, is very kind to Xiang Liang. Relatively speaking, the king of Sanqin is the real eyes and ears of Xiangjia. He wants to talk to the East, and the West monitors Xianyang.
In view of this, Liu Bang sent Guan Ying, who had made outstanding achievements, to destroy Sima Xin, one of the three Qin Dynasties in the East. When Liu Bang sent Guan Ying to lead the Han army to attack Liyang, the capital of Sima Xin, he also sent an army to attack Qixian in the north. After success, he pursued the defeated Yao Angjun, pacified counties such as _ _ _, and promoted Fan Kuai to the west.
At this time, it has been found that the situation is wrong, and the other side of the second Qin for help. Sanqin reinforcements joined forces to attack the Han army. However, Liu Bang let Cao Can defend in Jingling, blocking the attack of Zhangping and San Qin Jun for more than 20 days, which provided time for the Han army to destroy Sima Xin. Then the Han army returned to Cao Can and other countries to fight back against Zhang Ping and San Qin Jun.
4. Points from all over the country
After Sima Xin was destroyed, Liu Bangpa sent Cao Can, Guan Ying and Fan Kuai back to the army to continue the siege.
Li Shangyin was sent to pacify the northern land, and Li Shangyin led an army to pacify the monk army in the northern land, which is today's northern Shaanxi and western Inner Mongolia.

In addition, Ding Fu and Zhu Qiuping were sent to the county. Ding Fu and Zhu Qiuping led the army to attack the king of Beizhai in Gao Nu, and the king of Zhai captured Gao Nu and surrendered.
Zhou Bo and Jin Kui were sent to pacify Longxi, and Zhou Bo and Jin Kui led the army into Gansu, where they defeated the army led by Xian Cheng and occupied the county seat. Defeat the thief army and capture Tianshui Shang County, Gansu Province.
At this point, the Han army pacified most of Guanzhong, but the hills could not be abandoned.
In June of the second year of the Han Dynasty (205 BC), Fan Kuai was submerged by a deserted mountain, and Zhang Han committed suicide. The Han army completely pacified Guanzhong.
The battle of Sanqin lasted for eight months. After the victory, Liu Bang basically occupied the territory of Qin State during the Warring States Period, and had the capital of Qin Shihuang to destroy the six countries and unify the whole country, thus establishing a strong foundation for unifying China from Xianyang like Qin Shihuang.
Extended data
Analysis of the Battle of Chencang: Does it matter whether the battle of Sanqin is decided in Han Xin? Is the relationship between Yu Hanxin and the Battle of Sanqin important? Han Xin said Hanzhong was right, Han Wangxin also said the same thing, and Xiao He also said a similar Sanqin plan. Han Xin's Hanzhong theory is the least credible, and it is entirely possible that Sima's artistic creation transferred the story of Han Xin, the king of Korea, to Han Xin.
Xiao He's strategy of pacifying Sanqin: "May King Wang Hanzhong raise his people and make them wise, use Bashu to settle Sanqin, and make the world have a plan." -Liu accepted this strategy.
Hanzhong in Han Xin, Wang Han; "With Zhu Jin, Wang lived here and moved to the left today. The foot soldiers are all from Shandong, looking forward to returning, and can compete for the world. "Worship a letter to the Han Taiwei, soldiers will be slightly in Korea. -Han Wangxin finished Hanzhong, Liu Bang worshipped as Qiu, and Qiu was equivalent to the position of general, while Gao Zu had no general position at all.
And there is a record of going out after worshiping Qiu, and there is no record of going out after Huaiyin Hou Han Xin, indicating that Han Xin worshiped Qiu. It is obvious that Sima Qian put the worship of Qiu by Han Wang Hanxin on the head of Han Xin, the Hou of Huaiyin, and changed Qiu into a general, while Gaozu had no general position at all.
What Han Xin said is essentially the same as what Xiao He and Han Wangxin said, and nothing determines the strategy and tactics of Sanqin. In August, Hanwang used Han Xin's plan to return from the old road and attacked Zhang Han, the king of harmony. Han Xin put forward the plan of returning to the old road, but after Liu Bang led the army out of Hanzhong to return to the old road, Zhao Yan put forward other plans, which showed that Liu Bang used Zhao's plan of "returning to the old road" to defeat Chen Cang. Hanwang's plan to use Han Xin is the so-called "Hanzhong Right", not a plan to return from the old road. Moreover, Chencang Road was one of the roads leading from Hanzhong to Guanzhong at that time, which was basically a well-known road, so there was no need to give up the plan of taking the old road again.
