1. The overall situation and operational guidance before the war were due to the second year of Chu and Han Dynasties. In August 205 BC, Liu Bang was defeated by Cheng Peng. After completing the layout of Guanzhong in the rear area and returning to Xingyang, Wei, who was in the west, abandoned his illness when Pengcheng was defeated. When crossing the river, cut off Hejin and rebel against Han and attach Chu. So he left a deep impression on the traffic in Guanzhong, Xingyang, Chengdu and Weihe in the rear area. In order to remove this great threat and stabilize and consolidate the situation of refusing Chu, Wei is the only way. So he said to him, "You have the cheek to say Wei slowly. If you can come down, there will be Wei Qianhu. " Li Chiqi told the leopard that the leopard thanked him and said, "Life is like a blink of an eye. Today, Hanwang slowly humiliated people and called the princes of this department slaves. I can't bear to watch it again. " In return, Liu Bang sent Han Xin to attack it, and the battle of Wei started. 2. The geographical situation of the battlefield and the operational strategies of both sides: Pingyang, Dewey, Liyang and Handu, with the Yellow River as the boundary. Crossing the Donghe River from Liyang to Wei, you must pass an important ferry at Linjinguan. When crossing the Jin Dynasty, you can go to Anyi, an important town in Hedong since the Warring States Period, with today's Zhongtiao Mountain in the south, Jishan Mountain and Fenshui as barriers in the north. "The Warring States Policy" says: "If there is Anyi in Qin, then Han is not the supreme party, which is the disaster of Sanjin. Gai began outside the river and ended in Anyi. " "Yu Fang Minutes" said: "There is a stone gate on the state surface, but there is a warning sign on the back. The risk of controlling the bottom column is outside, and the advantage of good salt pond is included, as is Dong' ao District. " We can see its importance from these two books. Pingyang "connects the Party in the east, the Yellow River in the west, Bianluo in Nantong and Jinyang in the north". Kong Suoyun also said that "Huozhijing is the city and the source of Fenhe River", and Zigong also has the so-called "people who build rivers and mountains". From the situation of the two places, we can see the status of Wei and its importance in resisting Chu in the Han Dynasty, which is also the reason why Liu Bang was eager to control Wei when he laid out the core defense lines of Xingyang and Chengdu after the home front was set in Xiaguan. Tactics of both sides: Weibei allied with Zhao, west of the moat of the Yellow River, guarding the turn of Jin and Longmen, taking Anyi as the command center, preventing the invasion of the Han army, and completely adopting defensive and lasting operations. In order to avoid being blocked by the allied forces of Wei and Dai, quickly eliminate Wei Bao's resistance and avoid being delayed by Wei Jun along the Yellow River, Han Xin adopted a surprise attack strategy. One is to attack Anyi, the command center of Wei Jun, and then advance to Zhao and Dai. After the Chu-Han August War, Liu Bang wanted to feed his reward to Wei, so he decided to send troops to attack. Then, Han Xin was worshipped as the left prime minister, and he commanded the cavalry, such as Ru and Qijiang, to attack Wei. Liu Bang sent a general to assess the situation and asked, "Who is General Wei?" ? Yes, white matter. Liu Bang said, "You can't be my Han Xin, because you still smell of milk." . Ask again: "Who will ride?" ? Yes: Feng Jing. Liu Bang said, "Feng Ke is a general of Qin, and he doesn't choose his son. Although he is virtuous, he can't be a baby nurse. " Question 3: "Who will be the pawn"? Right: "other things". Liu Bang said, "If I can't be Cao Can, I will be safe." . Han Xin also asked Li Shichi: "Does Wei need Zhou Shu to be a general?" ? Yes, white. Han Xin said, "Stubborn ears". Liu Bang and Han Xin made the above judgment on the situation of the enemy. Later, Han Xin led Cao Can and Guan Ying. To the west of Xingyang, Linjin and xia yang are selected as the intersection.

The fact is that it is impossible to get in touch with the timber merchant. If this happens, Han Xin will make a surprise attack with infantry, and under no doubt, sneak into xia yang, so that it can attack Wei Jun's flank in the gold and gold in the south and attack Wei Jun in the east. Judging from this, Han Xin will continue to break through the main force of Wei Jun in the Jin Dynasty and nurse babies. He said that when the troops of the Han Dynasty arrived, Wei was afraid and led his troops into battle. Han Xin broke through again and captured Jiang Xiang alive. As a result, Wang Wei led the defeated troops to retreat eastward, and the Han army rushed to Quyang, which was once again breached, and the Han army continued to catch up. In September, Wei was captured in Dongyuan and returned to China. 4. Post-war political situation and comments: Han Xin has captured Wei, that is, he led his troops north to take Pingyang, the capital of Wei, and married Xingyang. So he appointed fifty-two counties in Hedong, and set up Hedong County, and sent the captured elite Wei Bing to Xingyang for reinforcements and garrison. In this battle, the strength history of both sides is not recorded. Judging from the total strength of Wei Jun, it far exceeds Xin-jun Han; However, Wei Jun's strength in the two major battles does not seem to be better than that of Han Xinqiang; Because of Han Xin's actions and Wei Jun's intentions, its resistance soon collapsed. Han Xin sent troops in August and captured Wang Wei in September, which shows that the war is fast. This battle in Han Xin is a surprise attack strategy of "defeating the enemy", "mistaking the enemy" and "luring the enemy". But "mistaken enemy" and "lured enemy" must be used according to "because of the enemy". For example, Han Xin concentrated his forces on Linjin Ferry because of Wei Jun, and devoted himself to the fortress of this ferry. As a result, Wei Jun was lured by the "suspicious soldiers" who crossed the river, so that he ignored his defense against xia yang and was able to sneak into xia yang. From this, we can get a concrete example and understanding of Sun Tzu's famous saying "defeating the enemy". It can be seen that "Principles of War" must be read in parallel with the history of war, so as to have a deeper understanding of the principles of war and not fall into "an armchair strategist". Then we can get new ideas and higher theories. Military scholars should pay attention to it!
