Shule River originates in the Qilian Mountains, is the second largest river in the Hexi Corridor, the upstream water is abundant and rapid, after entering the corridor plain, the water flow begins to become gentle, all the way west to the downstream Guazhou, the water volume gradually weakens, the river narrows, and the river becomes shallow.

However, the Shule River is mainly fed by glacial meltwater and rainfall, so from June to September every year, it is the month when the volume of water in the Shule River is the largest, after September, the rainfall in the upper Qilian Mountains weakens, the temperature drops, the glacial meltwater decreases, and the Shule River begins to enter the dry period, especially in the Guazhou section of the downstream, and some places can even leap across the river.

It is said that Xu Jin left Guazhou on August 16 to return to Beijing, while Turpan Mansuer Khan sent troops south to attack Guazhou on August 20, trying to win it in one go before the new commander of the Ming army gained a firm foothold.

However, Man Suer thought that Yu Dayou, the new coach of the Ming army, was a soft persimmon, but he hit a hard nail and almost nodded and broke the bloodstream.

Let's say that on August 20, the two generals under the command of Man Suer, Hu Li Na We'er, and Ya Lan led their troops out of Hami and went south in a murderous manner. Huli Na'er led 20,000 troops as the vanguard, and Yalan led 50,000 troops as the main force of support, and the momentum was huge.

Only two days, Hu Li Na we led 20,000 cavalry galloped to the north of the city of Guazhou Shule River, just as he was about to cross the river with a sheepskin raft, but was surprised to find that the Ming army actually built a continuous water village on the opposite bank, and also sent a large number of wooden rafts and rafts, etc., cruising on the river surface to patrol, the Ming army on the wooden platoon one by one moved skillfully, and acted like walking on the ground, at a glance it was a water skillful water army.

Hu Li Na was dumbfounded, obviously he didn't expect the Ming army to play such a trick and easily block his 20,000 cavalry on the other side of the river!

At this time, the Shule River is still in the end of the wet period, the narrowest part of the river surface is also about ten meters, the water depth is not over the horse's head, it is impossible to swim across the river, use the raft to cross the river, the Ming army sailors who are eyeing the opposite side are not vegetarians, and if they don't get it, they will send people to their heads.

I have to say that Xu Jin is not wrong, Yu Dayou is indeed a handsome person who can take charge alone, knows how to use his strengths and avoid weaknesses, and easily blocked the menacing Turbo cavalry with one move, and won at least a month of running-in period for himself.

Because the Shule River will enter the dry period for about a month, before the dry period comes, the cavalry of Turbo should not think of crossing the Shule River, unless they make a detour of hundreds of miles downstream and cross the edge of the Lop Nur Desert.

For the water warfare ability of the Yu family's army, Yu Dayou can be said to be quite confident, plus Xu Jin left him a very rich family background, more than 200 Franc machine guns, nearly 20,000 flintlock guns, and grenades and other big killing weapons, not to mention 20,000 Turpan cavalry, even if it is 100,000, he is confident that the enemy will block the other side of the river in the future.

The next day he launched a tentative crossing of the river, covering the nurses with bows and arrows to cross the river on a raft.

Yu Jiajun on the other side of the river sneered when he saw this, most of the Turpan soldiers were landlubbers, and the action skills of paddling rafts were laymen at a glance, and in the eyes of Yu Jiajun, who was "white in the waves", everyone was "white in the waves", it was simply sneering and generous.

Yu Jiajun did not rush to counterattack, and waited until a few sheepskin rafts in Turpan reached the middle of the river, and then a wave of sharp arrows and bullets swept over, and dozens of Turpan soldiers were beaten into a sieve on the spot, and even the sheepskin rafts were pierced, and even if some were lucky enough to be injured and did not die, they sank into the river and drowned alive.

Looking at the river water stained red by blood, as well as the floating corpses on the river, Hu Li Na we were angry and anxious, but helpless, the water village of the Ming army on the opposite side was well defended, although their bows and arrows could shoot across the river, but they could not hurt the Ming army in the water village.

Huli Na we do not believe in evil, and launched the second wave of temptation again, but this time I learned well, ran to a few miles downstream to put a raft, avoiding the Ming army's water village, as a result, the raft just rowed to the middle of the river, the Ming army's water village killed a few bow clippers, rushed down the river, and killed in the blink of an eye, and it was another round of shooting, and the Turpan soldiers on the raft were slaughtered.

Hu Li Na we roared angrily on the other side, and ordered the soldiers to release arrows to cover, but the Yu family army on the fast boat was experienced, and had already prepared shields and the like, and the cooperation was very tacit, some people raised shields into a wall, some people were responsible for attacking, some people were responsible for rowing, and under the cover of the rain of arrows on the opposite side, they still slaughtered all the Turpan soldiers on the raft, and then quickly collected their troops and returned to Shuizhai.

Even if someone accidentally falls into the water and immediately dives back to the shore like a fish, some people even simply dive under the opponent's sheepskin raft, take out a dagger and stab the raft through, and the Tulu soldiers on the raft fall into the river like dumplings......

After several attempts and the loss of nearly 100 people, Huli Na'er finally gave up crossing the river and stood still on the other side of the Shule River, probably thinking about a good way to cross the river.

Although there are not many enemies killed, it is a victory after all, the key is to successfully block the opponent's 20,000 cavalry, so Yu Dashuai's performance made Pei Xingjin and Jing Dachu and others shine, and the officers and soldiers of the three armies who originally doubted Yu Dayou's ability have also changed greatly.

Obviously, Yu Dayou's current performance has begun to be recognized by the officers and men of the three armies, and if there is another big victory, then the prestige of his new commander in the army can be gradually established.

However, Yu Dayou's mind is obviously very clear, although he desperately needs a big victory to prove himself, but he is not in a hurry, because now he can't make any mistakes, once he makes such a small mistake, the consequences are undoubtedly disastrous.

Yu Dayou knows very well that his age and qualifications are not good enough, and the group of people under his command are all proud soldiers who follow Xu Jin to sweep away the Tatars and subdue Warat, it is not easy to gain their recognition, on the contrary, it is easy for them to compare with Xu Jin, and the slightest setback will be infinitely magnified, and it will be even more difficult to bring the team.

Therefore, Yu Dayou has no plans to take further action for the time being, but fortunately, before the dry season of the Shule River arrives, it is not a problem to block the pace of the Turbo people, and there is still a month to plan properly.

In this way, Yu Dayou did not move, and the Huli Na'er on the opposite side wanted to move but couldn't, so the two sides faced each other across the river, until three days later, that is, on August 27, the veteran Yalan of Turva, who led the main army of 50,000, also arrived.

When Yalan learned that Huli Na'er had been blocked by the Shule River for several days, she couldn't help but be very dissatisfied, and called the latter to the tent and scolded her.

Originally, the status of Huli Na We and Ya Lan were equal, but Hu Li Na We lost Dunhuang and Guazhou and other places some time ago, and they were guilty of sin, and now they naturally have no confidence in front of Ya Lan, and they can only swallow their anger when they are scolded.

However, Hu Li Na'er is not a fuel-efficient lamp, although he swallowed his anger, but he also deliberately did not report to Yalan the details of his failure to cross the river, probably because he wanted to pit Yalan.

Sure enough, Yalan was fooled, and after playing his prestige in front of Huli Na Er, he immediately sent people to cross the river, and the result was naturally similar to Hu Li Na We'er, with a loss of nearly two hundred people, and a dozen sheepskin rafts, which was greater than Hu Li Na We'er's losses.

Glimpsing a trace of ridicule at the corner of Hu Li Na'er's mouth, Ya Lan finally understood that he was being put together, and he gritted his teeth in anger, but he was helpless, he glared at Hu Li Na Er'er fiercely, and suddenly collected his troops and returned to the camp.

In the big tent, Yalan called all the generals and staff under his command, and said in a deep voice: "It seems that the new commander of the Ming army is really not simple, he actually played such a hand, but he underestimated him before." Now that the Great Khan is in Hami, if our army is blocked here, it will inevitably make the Great Khan dissatisfied, do you have a clever plan to cross the river? ”

A staff member wearing a black hat said: "Actually, the general does not need to worry, it is now the end of August, and in about a month, the river will dry up, and then the river will narrow, and the prancing horse can pass, and the sailors of the Ming army will be useless." ”

Yalan frowned and said, "One month...... It's been too long, even if we wait, the Great Khan can't wait, if the army waits here for a month, and the army pays food and grass and doesn't talk about it first, the Great Khan will inevitably be angry, and then he will be blamed, and you don't think about it. ”

As soon as these words came out, all the generals and staff members were awe-inspiring, and the Great Khan was cruel and murderous, and once he was angry, he would kill people.

"General, why don't you take a detour downstream and attack Dunhuang directly? Even if you can't take Dunhuang for a while, you can temporarily give a message to the Great Khan if you take the Yumen Pass, right? A military general proposed.

Another general immediately chimed in: "The last general agrees, now that the main forces of the Ming army are gathered in Guazhou, the defense of Dunhuang must be empty. ”

Yalan's eyes lit up and said: "Good idea, which general is willing to lead his troops to attack Dunhuang?" ”

As soon as this remark came out, all the generals looked at each other, and the attack on Dunhuang had to take a detour through Lop Nur, and it was not a good errand to be caught in front and rear by the Ming army, if the supply of grain and grass could not be supplied, there was even a danger of annihilation.

Ya Lan couldn't help but look pale, and was about to have a seizure, when a flash of inspiration flashed in her mind, and she thought of a suitable candidate, and said coldly: "Come on, call the pioneer officer Hu Li Na and us." ”

The generals looked at each other and snickered when they heard the words, hehe, don't die poorly!

Soon, Hu Li Na we were called to the tent, when he learned that Yalan actually sent him to make a detour to attack Dunhuang, he couldn't help but scold his mother, but the other party was the main general, the military order was like a mountain, he didn't dare to disobey, so he had to pinch his nose and admit it.

The next day, Huli Na'er set up camp and led 20,000 cavalry to make a detour downstream.

At the head of Guazhou City opposite, Yu Dayou held his clairvoyant eyes and observed the movement on the other side of the Shule River with a serious expression, and he watched 20,000 Tulubo cavalry gallop downstream, but his face was like an ancient well without waves.

"Dashuai, the Turbo people are estimated to want to attack from the downstream bypass, with about 20,000 troops, we must take precautions as soon as possible." Zhao Dahe said in a deep voice.

Yu Dayou's tiger eyes flickered, and he said in a deep voice: "If the Tulu people want to make a detour to cross the river, they must pass through Lop Nur, and they will not be far from Dunhuang after leaving Lop Nur. ”

The herald took the order flag and went to herald.

"Lao Zhao, Dacheng, the defense of Guazhou will be taken care of by you for the time being, and Ben Shuai will go back to Guannai." Yu Dayou said in a low voice.

Zhao Dahe and Chen Dacheng glanced at each other, and nodded in unison.

Yu Dayou called Jing Dachu, the chief soldier of Xuanfu, to give a few words, and then left Guazhou with Qiu Luan and headed in the direction of Jiayuguan.

Jing Dachu couldn't help but wonder, now that the enemy is present, he really can't figure out why Yu Dayou entered the customs at this time, and took away the 5,000 troops under Qiu Luan's command, plus Pei Xingshen also led his troops back to Dunhuang, Guazhou's troops suddenly decreased by more than 20,000 people, isn't he worried that the Turbo army on the other side will take the opportunity to kill it?

Jing Dachu was worried, but he was a Buddhist, Yu Dayou didn't say it explicitly, he didn't bother to ask, just do his duty, his task is to defend Guazhou City, and nothing else.

Let's say that Yu Dayou left Guazhou with Qiu Luan, and 5,000 men and horses went all the way to Jiayuguan, until noon, Yu Dayou suddenly ordered to go north, and came to the Shule River, which is estimated to be seventy or eighty miles away from Guazhou downstream.

At this time, Yu Dayou ordered the whole army to rest, and after eating and resting for half an hour, he set off again and continued the march upstream along the Shule River.

Qiu Luan was full of doubts, rode his horse and walked a few miles behind Yu Dayou, and finally couldn't help asking: "Dashuai, aren't we going back to Jiayuguan?" ”

Yu Dayou said lightly: "Don't go back!" After saying that, he clamped the horse's belly and trotted up.

Qiu Luanzhang and Er King Kong were confused, so they had to frown and chase after him.

After walking about twenty miles upstream, Yu Dayou suddenly stopped, and his eyes lit up and said, "Okay, this is it!" ”

Qiu Luan fixed his horse and looked curiously at Yu Dayou's gaze, only to see that the Shule River passed through the gorge between the two mountains, and the water was turbulent, and after passing the cheek mouth, it became flat again.

"General Qiu, give the order to set up camp, the camp is on the high ground over there." Yu Dayou pointed to a nearby mountain ramp.

Qiu Luan suppressed the doubts in his heart, hugged his fists and said, "The last general will be ordered." ”

When the 5,000 men and horses set up camp on the hillside, it was already evening, Yu Dayou took Qiu Luan and five thousand households to the gorge between the two mountains, and pointed out: "Ben Shuai wants to build a dam here, and it must be completed within 20 days, can it be done?" ”

Qiu Luan and the five thousand households looked at the turbulent river at the mouth of the gorge, their faces became a little difficult to see, although the mouth of the gorge in front of them is not wide, less than thirty meters, but the water is deep and rapid, it is too difficult to build a dam in twenty days!

Yu Dayou raised his eyebrows, stared at Qiu Luan with tiger eyes, and said: "General Qiu, can you do it, if you can't do it, Ben Shuai will replace someone else." ”

Qiu Luan suffered a defeat in the Northern Expedition, not only lost more than 100,000 stones, grain and grass, but also led to the annihilation of the whole army, and later even the title was deprived by Jiajing, and now he finally got a job, of course he didn't want to do it, and hurriedly gritted his teeth and said: "The last general can do it, please rest assured!" ”

Yu Dayou nodded, and said in a cold voice: "The army has no jokes, if you can't do it at that time, and you miss the big thing of the marshal, then don't blame the marshal for not being emotional!" ”

Qiu Luan and the five thousand households are all awe-inspiring!

The next day, Yu Dayou left with his own soldiers, and Qiu Luan went crazy and ordered people to collect timber and stones, and start building a barrage dam.
