There are two small countries along the ancient Qing Fashui coast, one is called the second country, and the other is called the Zhen country. The second country is located in the southwest of Yingshan in present-day Hubei, on the east side of Qingfa Shui; Zhenguo is located in the south of present-day Anlu County, Hubei, on the west side of Qingfa Shui. There is also a small country called Yun between the two and the second. Yun Guo had a point of conflict with the two countries, so he asked the people of the country to retaliate against the two countries. Considering that their own strength was too weak, even if they united, they would not be able to confront the accompanying army, so they sent people to ask for help from the state of Chu.

In the spring of the eleventh year of Duke Lu Huan (the year of the death of Duke Zheng Zhuang), the state of Chu accepted the request of the two countries. However, since the two sides did not have diplomatic relations, the Chu people were prepared to enter into an alliance with the two countries first. The location of the alliance was set in the triangle where the Qingfa Water and the Han River meet. King Wu of Chu disdained to meet the king of a small country, so he sent the crown prince Mo Ao Qu to attend in his place; The three kingdoms planned to attack Yun after signing the alliance.

The people of Yun were not willing to sit idly by, and they went to Sui, Hang, Zhou, and Yufang to ask for help. The four countries believed that if the state of Chu formed an alliance with the two countries, it would be equivalent to opening the door to the east; The Chu army can bypass Suiguo to cross the Qingfa River to the east, reach the Huai River valley to the north, enter the Dabie Mountains to the east, and enter the Yangyue region to the south; At that time, all countries in Handong will suffer greatly. Shikoku agreed without hesitation.

The armies of the four kingdoms had already set out separately, and the Yun army had driven out of the city and was stationed at a place called Pusao on the outskirts, and they planned to wait for the reinforcements to arrive and fight a decisive battle with the Chu army, driving the enemy into the Han River to feed Wang Ba.

The time for the alliance has not yet arrived, and the two people are blocked by the Yun people in the east of Qingfa Shui, unable to reach the alliance land; The sedent did not dare to rush to go alone.

As soon as the Chu army crossed the Han River, unfavorable news came one after another. Qu Bin had to order a halt to the march and convene a military meeting on the spot.

Qu Bin is a headache from the current situation. Dou Lian disagreed, he said: "The Yun people are stationed in the suburbs, and behind them is the city, and the reinforcements are about to arrive; In the event of a fight, they can safely retreat into the city immediately, so their guards must be relaxed. Therefore, please lead the prince to retreat to the suburbs to intercept the reinforcements of the four countries, and I will lead a sharp division to launch a surprise attack on the Yun people at night, and the Yun people will inevitably fail if they are unprepared. Once the Yun State is defeated, the Four-Power Alliance will return without a fight. ”

"I think it's better to ask the king for more troops," Qu said. ”

Dou Lian said: "Winning lies in the unity of hearts, not in the quantity." Back then, King Wu Keshang broke hundreds of thousands of merchant troops with 3,000 tigers, and you also know it. What does it matter if the enemy is already in formation? ”

Qu Bin said, "Then do divination." ”

Dou Lian said: "Divination is to solve doubts, what is divination without doubts?" ”

The battle plan was thus decided, and Qu Fang led the large army to cross the Han River to the west again; Yun Ren found out that the Chu army was turning around and returning to the division, and his psychology was completely relaxed.

With an elite army of veterans of many battles, Dou Lian quietly approached the enemy camp under the cover of night. Thinking that the crisis had been resolved, Yun Ren began to celebrate the victory in advance. The generals ordered the wine and meat to be brought from the city, and everyone got drunk, and then fell asleep wherever they wanted, and some even deserted and returned home.

The Chu army launched a surprise attack at midnight, and the Yun people had absolutely no idea what was happening, and many were killed in their sleep; The drunks could not find weapons or sequences in the confusion, so they stumbled and fled in the direction of the city. The Yun division suffered heavy casualties, and the reason why they were not completely annihilated was entirely because the Chu army was too small in number.

The reinforcements from the four countries turned around and returned home after hearing the unfavorable news. After the defeat of the Yun people, the second and second armies were able to reach the territory of the alliance. Qu Bin also rushed back from the suburbs, and the three kingdoms formally formed an alliance.

After the alliance, the people of Chu decided to break the anti-Chu alliance one by one. The first to retaliate was the Hangguo, which was located west of Yunxian County, Hubei Province and north of Hanshui, a small and remote country, isolated and helpless.

In the summer of the twelfth year of Lu Huan (BC700), the state of Chu sent out to fight and hang.

The most convenient way for the Chu army to march was to travel upstream by boat, but it had to pass through the section of the river controlled by Deng and Lu. However, King Wu of Chu did not trust the people of Lu and Deng; The reason is that when the troop carriers of the Hangshi Division came and went on the Han River last year, Lu and Deng knew that the purpose of the Hangren's trip was to fight against the Chu State, but they still turned a blind eye to them and allowed the enemy ships to pass back and forth.

The Chu army was afraid that the trip would be intercepted by the two countries, so they abandoned the water route and took the land route instead.

The commander of this operation is still Mo Aoqu. King Wu of Chu was in his sixties at this time, and he did not know how much time he had left, and he only hoped that the crown prince would be able to lead the army to victory independently, and gain status and prestige by establishing military exploits.

The overland march was a chore, with many mountains and rivers to cross along the way from Danyang to the country of Hangguo. The hot and humid climate of summer makes people breathless, and the soldiers are often sweating profusely, and they have to watch out for the ubiquitous mosquitoes, poisonous snakes and cannibals. The Chu army marched with great difficulty, and the army was exhausted by the time it entered the border of the Hangan State.

The city is small and strong (because there are many nearby mountains), and the terrain outside the city is complex and narrow, so that even a complete queue can not be arranged, let alone arrange a large number of siege equipment.

There was not much time left for the Chu army, and the generals kept scratching their heads. Due to the difficulty of the march, the Chu army brought very little baggage. Qu Bin ordered the army to be stationed outside the south gate, and the generals inspected the terrain near the Hangguo and then launched several small attacks; Because the attacks were all tentative, they were all repelled by the hangers. Qu Bin found that the hangers were particularly fierce and greedy, and they hardly spared any enemy: they treated their prey like ants, dragging them into the city, dead or alive.

Qu Fang decided to develop a battle plan based on the characteristics of the hangers. He said at the pre-war conference: "If you are greedy and rash, greed will see profit and forget danger, and rashness will be reckless." We ordered some woodcutters to go to the mountains to chop wood, but instead of protecting them, we used them as bait, and when the enemy took the bait, the main force of our army was able to destroy the enemy outside the city. ”

The Chu people then released a batch of bait. The woodcutters ran in droves to the woods near the city gate and cut branches. The hangers watched the city with great joy and found that there were no soldiers around the woodcutter to protect him; They immediately ran out and robbed about thirty woodcutters as trophies. Those who grabbed it lost sleep excitedly, and those who didn't grab it suffered insomnia depressedly; The hanging people thought that the Chu people were short of firewood, and they would definitely send more people to chop firewood on a cloudy day, so they all wanted to grab another handful of firewood.
