Zhang Handan was out of Guanzhong for a few months, destroying Chen Sheng, the king of Zhang Chu, Wu Guang the false king, Wu Chen the king of Zhao, Wang Gui of Wei, and Tian Dan, the king of Qi, and killed the corpses of Zhongyuan all over the field. What Zhou Wen and Xiang Liang, who had made great achievements in the front of the battle, could only lead the neck to kill in front of Zhang Handan. However, Xiang Yu divided the princes, and Zhang Handan was named the Yong King, one of the Three Qins, and after that, facing Liu Bang, it seemed that he was defeated very quickly.
The Three Qins were the Yong King Zhang Handan, the Sai King Sima Xin, and the Zhai King Dong Feng, of which the Sai Kingdom and the Yong Kingdom were divided into Guanzhong East and West, and several passages from Hanzhong to the north almost all pointed to the Yong Kingdom, and the Yong King Zhang Handan was also the strongest of the Three Qins, and his strategic layout determined the overall situation of Guanzhong.
In addition to defending Against Liu Bang, the King of Han, Zhang Handan also had to defend against The Western Wei King Leopard, the Yin King Sima Jiao, the Henan King Shenyang, and the Marquis of Yong.
When the time king Zhao Xie and Chen Yudong jointly attacked Zhang Er, the king of Changshan, Zhao Xie was King Xie of Zhao before Xiang Yu was divided, and most of the fiefdoms were given to Zhang Er by Xiang Yu, and Wang Xie only got the dai land in the northwest of the Zhao state, of course, he was resentful.
To the east of the kingdoms of Zhai and Sai was the State of Western Wei, and the Western Wei King Leopard was the Wei King Leopard before Xiang Yu was divided, and his original territory was merged into the Western Chu State of Xiang Yu, the overlord of Xiang Yu. Dai Wang Xie led his army east across the Taihang Mountains, but the Western Wei state did not attack the empty Dai state north, indicating that the Dissatisfaction of the Western Wei King Leopard with Xiang Yu was already traceable. If the Western Wei king Leopard wanted to oppose Xiang Yu, perhaps he would not dare to cross the Taihang Mountains to expedition to Dong County and Yan County, would he cross the Yellow River to attack Zhai guo or Sai guo? If you only look at the strength of the troops, the western Wei king leopard's men and horses are no less than Liu Bang in Hanzhong. For Sanqin and Zhang Handan, it was necessary to guard against Liu Bang, and even more to prevent Wei Leopard.
In the Three Qins, the state of Sai, on the east side were the state of Yin and the state of Henan, the king of Yin, Sima Wei, and the king of Henan, Shenyang, who were still sworn enemies of Sima Xin, the king of Sai, a year ago, who could guarantee that they would not enter Guanzhong in the west. East of wuguan in the state of Sai, that is, the sphere of influence of the Marquis of Yong, he and Liu Bang raised troops in Pei County at the same time, will they attack Guanzhong from the direction of Wuguan?
No matter who attacked the kingdom, Sima Xin knew best with a few pounds and a few chapters and two chapters, and when the time came, he would definitely have to fight the Yong King's personal conquest.
Zhang Handan not only had external troubles, but also many internal contradictions, after all, he was not the Qin State Sect, his father was still Korean, 200,000 Qin troops were buried in his hands, and the Qin people could not bow down. For example, Zhao Ben and Nei Shi Bao, two of Zhao Gao's cronies, commanded 20,000 Qin soldiers and occupied a large area of land near Xianyang, the old capital of the Qin Dynasty, which was considered to be the state of Yongguo.
Zhang Handan's most urgent task now was to first replace the defenders of the cities and towns in various parts of the Yong Kingdom with his own cronies, gradually control the Yong Kingdom, and then find a way to digest and annex the territory of Zhao Ben and Nei Shi Bao. Of course, during this period, Zhang Handan did not have many troops to guard against the Western Wei king Leopard, the Han king Liu Bang, the Yin king Sima Jiao, the Henan king Shenyang, and the Marquis of Yong.
After several months of layout, Zhang Handan himself sat in the ruins of the hill, his brother Zhang Pingtun bing Haoxi, Xianyang in the hands of Zhao Ben and Nei Shi Bao, Chen Cang and Dasanguan were still controlled by the original shou generals. North of Guanzhong, the Longdong Plateau, the former Qin Dynasty in the north and north of the northern region, Zhang Handan controlled about half of the city. His subordinates shouqi county (姚卬镇守柒县); Zhou (周類镇守栒邑; Su (苏駔镇) shou niyang (苏駔镇) and Wu (武氏) submitted to Zhang Handan (章邯) and worshiped him as the general of Yong.
Xi County in Longxi was the territory of Baima Qiang, whose leader, Thief Ba, submitted to Zhang Handan.
What Zhang Handan lacked most now was time, if he gave Zhang Handan two more years, he should be able to control most of the territory of the Yong Kingdom, and perhaps also annex Zhao Ben and Nei Shi Bao, at that time, even if Han Xin commanded the Han army to go north, it would not be easy to eat Zhang Handan.
Judging from the layout of Zhang Handan, internal and external troubles, in the face of the Han army in the north, the Yongguo army surrendered quite a lot, this is not entirely The problem of Zhang Handan, this is also the time, luck, and fate.
