On the third day of October, the last barrier for warm water to flow into the Kunming Basin, Kunze County.

Zhang Fei, who pacified the six counties around Dianchi, finally left only a few hundred people in each county to guard Anmin, and the rest all gathered in front of the Kunze battlefield to block the river valley with Li Su and Wang Ping. Zhou Tai was transferred by Zhang Fei and went to Dianchi to guard the town, taking into account the deterrence of the newly attached people and the tribal chieftains.

With the arrival of Zhang Fei, the strength of the Han army on the frontal battlefield reached 4,000 people. But just because he had to wait for Zhang Fei to arrive, Jing Yi's main force of Jianning County soldiers also arrived one after another, so Zhang Fei's 4,000 people had to face 20,000 people. Although 20,000 people were blocked in the valley by the closed door and beating dogs.

If you take out a map of Jianning County and look down, you can find that Guan Yu blocked the north entrance of the Wenshui River Valley in the valley between Cunma County and Wei County, while Zhang Fei blocked the south entrance of Kunze.

Of the 40,000 people in Jing Yi's coalition army, 20,000 of the guests stayed in Wei County (Qujing) on the north side of this river valley, and Jing Yi's own 20,000 people stayed in Tonglao County (Luliang) between Kunze and Wei County.

But because Yunnan in this era did not open terraced fields after all, the grain output of Weixian and Tonglao must be far from being compared with Qujing and Luliang in later generations - a small half of the fields in Qujing, a prefecture-level city in later generations, were terraced fields, and now they are completely barren mountains and forests.

At this point in the war, the situation was already very good for the Han army, although it was necessary to deal with five times as many enemy troops on each road, but as long as they were blocked and defended to avoid the battle, the enemy could be dragged to death sooner or later.

As long as the Han army controls the grain storage in the Kunming Basin, it can do it as many reinforcements as it wants to send from the waterway to reinforce in the future, and there is no need to worry about the problem of insufficient food to eat.

However, Zhang Fei, who has always liked quick battles, when he arrived in Kunze on the first day, he couldn't help but immediately go up to the city to check the enemy camp, and made a statement:

"What a chance! When the three or four thousand men of the vanguard had just arrived, they had come down the river for nearly two hundred miles in one day and one night, and all the soldiers were exhausted.

If Yuhei and Zi had been allowed to take the initiative to attack, or set up ambushes on the mountain roads on both sides in advance, and beat him with a hooded head and tail while the enemy had just come to gain a foothold, at least 2,000 enemies could be annihilated!

It's a pity, we missed it in vain, although we rushed back, Jing Yi's rear army also came one after another. Boya, the eldest brother has always said that you have no last resort, and you have also been too cautious and missed the fighter! ”

Zhang Fei's words, judging from the results, are indeed correct.

The Art of War: When Jing Yi was in such a hurry to return to help, and the troops were stretched out into a long snake formation and could not take care of each other, Zhou Tai and Wang Ping really fought radically and set up an ambush, and it was entirely possible to annihilate the enemy's vanguard at a very low cost.

It's all because Li Su is too stable, he missed the fighter in vain, and he can only wait for the enemy to attack the city and camp, and Zhou Tai Wang Ping to defend it, so that the lethal ratio is not as good as the first wave of sneak attacks while the enemy is not firmly established.

Li Su's heart is also full of groins: Is it wrong for Lao Tzu to seek stability? You're a complete hindsight! How do I know that Jing Yi will have more than Zhang He's grass bag? Isn't it right to anticipate the enemy's wideness and leave more margin?

Li Su was angry in his heart, and he was not polite to Zhang Fei, and directly retorted: "It is a small matter to miss the fighter plane and fail to annihilate the vanguard of the two thousand enemy troops first, and to frustrate its sharpness, the key is to be stable!"

If there was a mistake in the ambush at the beginning, causing the enemy army to take advantage of the situation and sneak over the dangerous place from the east bank of the warm water in the east of the city and enter the Dianchi Basin, it would be called a catastrophe! In that case, we, a few thousand, will have to fight against 20,000 rebels in the open field on the shore of Dianchi Lake! ”

Li Su was beating his words, and he still secretly thought in his heart: Zhang Fei's tactical acumen is good, but he is still greedy for merit, and he is reluctant to miss it when he sees a fighter. Especially in the past two years, Liu Bei's camp has been too smooth, he was injured twice and was in distress again, and the scar forgot the pain.

Does Zhang Fei have to be seriously injured every three years to have a long memory? A cautious shelf life of only three years for a serious injury?

Of course, Li Su also admitted in his heart that the reason why he was so stable this time was that he was frightened by Zhuge Liang Ma Tan's lesson, and he became more and more reluctant to make moves under the psychological shadow.

Fortunately, Zhang Fei still remembered Liu Bei's explanation, and his mood was okay, so he quickly obeyed: "Okay, the eldest brother said that you are a military advisor and you are the governor, and they all listen to you!" Then you say, now that you have lost the opportunity to take advantage of the unstable foothold, how can you fight the battle in the future? We're here to stay? ”

Li Su also quickly had a countermeasure: "First hold on for ten days and eight days, so that the enemy army will be tired and frustrated." We shout from the city every night, but we don't send troops to harass, and we carry a truth in the nine falsehoods, and we can kill as many people as we can rob the camp. The enemy organized resistance and immediately withdrew.

When the enemy army can't stand it anymore, we will take the initiative to attack the city, and we will kill and wound them in the defense. Either they will retreat and set up camp and distance themselves from us a little more - when they retreat and set up camp, you will rush forward with your cavalry, kill some lone enemy soldiers behind the palace, take some prisoners, and confirm the composition of the enemy army.

I want to know whether Jing Yi's main force is on our side or Yun Chang's side. When the time comes, the side facing Jing Yi's troops will be mainly defended. In the face of the distant side of the Yue Barbarian Qin Zangman, he focused on attacking, and he had to attack while attacking, spreading the divine soldiers of our army from the sky and having divine help to ward off poison.

The barbarian soldiers are more superstitious than the Han soldiers, as long as they add fuel and vinegar to see our feats, they will definitely regret the military heart to help Jing Yi. Let's not divide and surrender much, just give the first one who surrenders Xu a benefit, and then immediately start to break that side, and the follow-up will be easy to say.

Jing Yi can still hold on now, because the two county towns in the valley, Wei County, Tonglao, still have some grain reserves, and if we arbitrarily seize the grain reserves of one county, their 40,000 soldiers and horses will not be able to eat the spring famine next year and will starve to death. ”

"Use rumors of gods and ghosts to scare the barbarians into surrendering? Okay, let's arrange it. Zhang Fei's mind couldn't turn for a while, but after a little pondering, he had to admit that Li Su was too vicious, and even used ghosts and gods to attack his heart.

……

In the next few days, everything went according to Li Su's plan, and Zhang Fei let the soldiers sleep at the head of Kunze City for three consecutive nights, similar to what Zhuge Liang did in the historical Battle of Hanshui when he was tired and forced Cao Cao to retreat.

But who knew that the effect of exhausting the enemy in the first two days was better, and every time the noise sounded, Jing Yijun got up in a hurry and lined up, and found that no one went back to sleep, and the toss was very unbearable.

But for two consecutive nights, the Han army did not really encounter the robbery of the camp, and on the third night, Jing Yi actually let the soldiers sleep directly, and they couldn't get up after listening to the drums. Zhang Feibai knocked all night.

So on the fourth day, Li Su judged that Jing Yi was used to bluffing, and couldn't help but shake his head secretly: "Lao Tzu really thinks highly of you, and treats you as cautiously as Cao Cao." Cao Cao also knows that we must beware of the nine falsehoods with a truth, and you can't be lazy with the truth and the truth, you actually sleep directly, okay, fulfill you. ”

Li Su, who was once tossed in vain because of his steadiness, was of course a little angry, and the consequences were also very serious.

If you don't let you have some blood, next time Yide sees us cautiously and laughs at us for fighting wits and courage with the air, then how can we hold the scene?

Jing Yi must be allowed to pay tribute to Li Su's prudence! In this way, the generals of the Han army knew that Li Su's caution was necessary!

That night, the second time there was a noise in the middle of the night and Jing Yi was still sleeping, Zhang Fei really rushed out with Li Su's more than 1,000 escort cavalry - as mentioned earlier, the Han army's 7,000 troops around the rear this time, 5,000 barbarian mountain infantry, and 2,000 cavalry. So far, it is still possible to make up more than 1,000 cavalry to rob the battalion and attack at night.

Jing Yi, who had been paralyzed for three and a half nights, was directly rushed by Zhang Fei to bomb the camp, and even some soldiers didn't realize that it was Zhang Feizhen's cavalry who stepped on the camp when their comrades had begun to be slashed and killed, and thought it was an empty shout, and many screams were covered by shouts.

Well, at this moment, there is no need to wait for Jing Yi to move the camp on his own, overnight, those who were trampled and killed by the cavalry, plus those who trampled on each other in the desertion and chaos, the total loss exceeded 5,000 people! One or two thousand of them were taken prisoner.

Jing Yi was robbed of a camp of 1,000 people, knocked out 30% of his troops, and fled back to Tonglao County with the remaining 10,000 people, and closed the city gate to station, which can be regarded as stabilizing his position.

They all retreated forty miles and returned directly to the city, which saved the trouble of camping. The tents in the camp and the food that was finally transported to the front line were all directly seized by Zhang Fei.

As for the captured prisoners, it couldn't be easier to pry out the military intelligence information from their mouths, and after a little isolation and review, it was immediately asked:

The troops here are all Jing Yi's Jianning County soldiers, and Jing Yi has transferred almost all the Jianning County soldiers, and less than one or two thousand people remain in Wei County, and more than eighty percent of Wei County's defense is carried out by reinforcements and brute soldiers.

I have to say that it is quite a coincidence, Guan Yu and Zhang Fei originally planned to scratch their tongues and torture the military situation, but every time they originally planned to explore the military situation, they were all because of the enemy's carelessness and ignorance of the soldiers, and the result was a battle of overcoming and defeat.

Investigating the military situation and finding out that he directly kicked the enemy's checkpoints and camps, there was no one.

"Okay, it seems that everything is as we expected, find a way to send the order to Yun Chang, let him be the main attacker, divide and disintegrate the barbarians." After Li Su understood it thoroughly, he immediately decided.

In fact, he estimated that Guan Yu himself could figure out that "the northern front will be the main attack in the final stage" - although since Li Su entered the Kunming Basin, the news between Guan Yu and Guan Yu's army on the northern front has been cut off, and Guan Yu has never directly received the news that "Li Su has succeeded". But I believe that with Guan Yu's knowledge of the soldiers and the observation of the clues of the frontal enemy mobilization, he will definitely be able to guess.

But Li Su still had to find a way to delay the time to make an appointment with Guan Yu, after all, he needed to explain his courage and the details of how to break through the natural danger of smearing water, and how to improvisate and use ghosts and gods to scare the barbarians, and these details of his words were clearly explained to Guan Yu.

On the day the messenger sent it, Zhang Fei couldn't help but complain: "We can't send a letter directly to the second brother along the mountain road, doesn't the messenger have to go back with water first, and then abandon the ship and land on the shore halfway and go around in a big circle?"

Even if it is much faster to go down the river than to go upstream, the second brother will not be able to receive our letter in more than ten days, so it is better to directly attack Tonglao County. ”

Li Su was angry and funny: "You won't kick the camp and win a battle, right?" Only after kicking the camp to win did he defeat Jing Yi with 30% of his troops, who gave you the confidence to use 4,000 elite soldiers to attack a city defended by 15,000 miscellaneous soldiers? Don't worry, we originally planned to spend the whole winter and spring to recover Jianning County and Yongchang County, but now it's only early October, and there is still time. ”

Li Su and Zhang Fei continued to lead troops to block the road, they squatted in Kunze County, Jing Yi squatted in Tonglao County, separated by forty miles of river valley mountain roads, no one took the initiative to attack, and they held on to each other peacefully.

But ten days later, Guan Yu finally received the latest military information from Li Su's side, painted a voice, and taught him how to bluff and brag about attacking the reinforcements in the letter.

Guan Yu looked at it again and again, and finally knew what to do.

Anyway, the two counties where the enemy is trapped in the mountain road will die early and die late, so it's better to end their suffering as soon as possible.
