Mao Dun Shan Yu told his generals that he had his own clever strategy, and he could bypass Yin Mountain and take the hinterland of Great Qin directly, and kill the Qin army by surprise.

When the generals under his command thought of Daqin's flowery world, their eyes immediately lit up with lust, and they complimented Mao Dun: "Please Da Dan Yu guide us to the clear road, go to the fertile soil of Daqin, and enjoy the eternal bliss!" ”

Mao Dun was excited for a while: "Order the vanguard, tomorrow to the place where the Liyin Mountain is two hundred miles away, detour to the west, walk five hundred miles towards the place of sunset and then to the south, from the grassland of the old Dayue clan to the east, and divide into two roads, all the way to attack Yanmen Pass, all the way to attack Longxi, after we enter the Qin land, we will directly take the straight road repaired by the Great Qin Emperor, and go in to surround Xianyang, hahaha!" ”

Shan Yu was too proud of his shrewd strategy, and his subordinates complimented him again for a while, but they didn't know that Meng Tian's army had been waiting for them to die.

Mao Dunshan Yu said: "The 100,000 Xiongnu elites of the rear army are stationed fifty miles away from Yinshan, ready to meet the two armies in front at any time. After the generals received the order, they carried it out one after another.

On the night when the Xiongnu army was still 500 miles away from Yinshan, Meng Tian drove the cavalry and chariots of Yinshan out of Yinshan and advanced north for a hundred miles before resting.

The next day, the Xiongnu's vanguard army of more than 800,000 soldiers and horses marched south, and Meng Tian also marched north with a mixed army of 100,000 cavalry and military vehicles.

He concluded that it was the soldiers and horses used by the Qin general Meng Tian to lure the enemy, and ordered the former army to turn around and head west two hundred miles from Yinshan, so that they only needed to resist the Qin army that lured the enemy, and did not have to entangle with it.

Some Xiongnu generals wanted to take the opportunity to eat this Qin army, but they were all strictly ordered to stop Mao Dun Shan Yu, which shows that Mao Dun Shan was carrying a human head on his shoulder, not a pig's head, and he was not greedy for small profits, otherwise he would lose a lot because of a small loss.

Meng Tian's 100,000 army came into contact with the Xiongnu's vanguard troops, and the Xiongnu's 400,000 troops entered Meng Tian's preset ambush circle, and Meng Tian personally set up a formation to meet the Xiongnu front army.

These 100,000 soldiers and horses were secretly brought out by Meng Tian from Jiuyuan County, and they practiced in the city for more than two months.

In less than half an hour, the "Checheng Circle Array" was arranged, and his array was much better than Han Xin's previous layout, firstly, he was well prepared, and secondly, he was more thorough than Han Xin's research.

The generals of the Xiongnu front army couldn't help but be surprised when they saw the large array of the Qin army, how could the marching army suddenly become a "big city" in front of them? And this "big city" that stretches for miles is still slowly moving!!

When Mao Dun's order arrived, the command flag of the Xiongnu front army began to wave, the army began to charge forward, hundreds of thousands of war horses galloped to make the earth shake violently, and the banner in Meng Tian's circle array also waved, commanding freely.

In an instant, the crisp sound of Qin crossbows sounded in the east, west, and south directions of the Xiongnu, followed by the crossbow arrows that covered the sky and the sun and tilted down on the heads of the Xiongnu army.

The cavalry of the Xiongnu had heard that the power and range of Qin's crossbow were twice as far as their own bows and arrows, but at this moment, the hundreds of thousands of crossbow arrows shot from the grass on the east and west sides made them unable to guard against it???

These sudden sneak attacks, the Qin army shot countless crossbow arrows, and in the first round, more than 10,000 Xiongnu horses lay on this grass forever. The Hun cavalry, who was already very afraid of being ambushed, found countless crossbow arrows shooting from both wings at this moment, and knew in their hearts that they had fallen into the ambush of the Qin army again, but they still had to desperately beat their horses and rush forward to kill.

Meng Tian's army, except for a large circle in front of it that spanned several miles, slowly moved to the back, turning into several smaller circles. However, there was still a large "Checheng Circle Array" slowly moving towards the two wings, as if it had been agreed, moving along the grass in front of the grass that kept shooting crossbow arrows and moving north, and kept shooting crossbow arrows.

The Hun cavalry was continuously shot by the Qin crossbow for half an hour, and the Xiongnu's front army failed to move forward, but paid the price of more than 50,000 people.

The herald of the front army reported to Mao Dun that the front army was ambushed and shot on three sides three hundred miles from Yinshan, and Shan Yu immediately ordered the whole army to stop advancing, and the Chinese army rushed up to rescue the front army and retreat, and rearranged the strategy of marching.

When the order to retreat came, two hours had passed, and the crossbow arrow attack of the Qin army, the former army of the Huns, was suppressed, and there was no way, and they also tried to rush left and right. But as soon as they rushed over, the crossbow bolts immediately encrypted and fired at the horses, and the cavalry trampled on each other and suffered more casualties.

Finally got the order to withdraw the army, and the Xiongnu had already lost more than 100,000 soldiers and horses. The Huns just began to retreat, Meng Tian's "Checheng Circle Array" rear flag waved again, the front of the car array "city wall" instantly spread to both sides, the cavalry behind were arranged into three arrows in a long formation, the overall fan-shaped array rushed forward to kill and move.

These charging cavalry are the elite cavalry that Meng Tian has trained in Jiuyuan for many years, and neither the equipment in their hands nor their combat effectiveness are comparable to the Hun soldiers. They also have the cooperation of the battle formation, like a wolf entering a flock of sheep, frantically slashing and killing the Hun soldiers.

The chariots that retreated on both sides drove to the Qin army in the ambush circle on both sides, and where the Qin cavalry arrived, the crossbowmen who had been in ambush for more than two months ran out one after another, loaded the Qin crossbow and the remaining crossbow arrows onto the chariots, and retreated south one after another.

The former army, which was devastated by the cavalry of the Qin army, ran north like a lost dog, and just collided with the Chinese army that came to meet them, and at the same time, there were crossbow archers of the Qin army who had not retreated at their junction lying in ambush on both sides and shooting wildly.

Suddenly, the Xiongnu were in chaos, they could not form an army, trampled on each other, and even slashed each other in order to escape for their lives, and the chaos lasted until late at night, and then slowly stopped.

After an overnight count, the Xiongnu lost more than 200,000 soldiers and horses. Due to the preparation of this unexpected ambush shooting and cavalry charge in advance, Meng Tian ended the pursuit before dark, and the crossbowmen who had been in ambush for more than two months on both sides returned to the cave of Yinshan on the chariot.

The cavalry that the rear army charged and the crossbowmen who originally cooperated with the cavalry on both sides rode or brought back the war horses left by the Huns when they withdrew. According to statistics, the Jiuyuan army lost more than 10,000 soldiers and horses, and brought back nearly 100,000 Hun war horses, which can be regarded as a complete victory.

It turned out that when Meng Tian was in Xianyang, the military order issued to Li Xin was to ask Li Xin and the veterans of the Jiuyuan army to carry a map of 500 miles around Yinshan drawn by Meng Tian, which recorded all the surrounding mountains and rivers, and arranged ambush caves 300 miles north of Yinshan, and repeatedly emphasized the places where the Xiongnu went south and passed, and the layout of ambush caves.

Meng Tian also detailed the way to avoid the Xiongnu Tanma, that is, to make the long grass in the grass hang irregularly, as if it was chaotic, so that the Hun Tanma did not want to go up. The soldiers' daily training and the plan of cooking and drinking at night were exactly the same as in Yinshan in those years.

The Xiongnu had only recently sent a horse south, and they could not find the ambush circle that had been arranged two months ago, so they fell for Meng Tian's plan to ambush the troops. In one day's battle, with a casualty ratio of more than 1 to 20, more than 200,000 Xiongnu soldiers and more war horses were lost.

When Meng Tian led the army to retreat to Yinshan, it was already late at night, so he ordered the army to rest and recuperate.

The next morning, Meng Tian raised his tent in the cave of Yinshan to arrange for the transfer of troops. Time was very short, Meng Tian did not discuss the change with his generals, and issued the battle plan agreed with Li Xin in Jiuyuan as an order:

"First, the herald immediately returned to Jiuyuan and ordered Li Xin to hang Meng Tian's flag on the Jiuyuan Great Wall, and the flags were densely covered under the Great Wall, and at the same time, the chariots were arranged into a large array, and more than 10,000 crossbow archers were arranged in case of accidents.

Second, Li Xi led 20,000 Jiuyuan cavalry to quickly hide outside the Yanmen Pass from the "Second Straight Road". Cheng Zhiyi and the Mongol army (the Mengtian general of the Mongol family) took the guide and led 50,000 crossbow archers and 30,000 Qin crossbows to the designated place on the map to ambush, and carried out sorties and shot the Xiongnu according to this tactic. ”

After finishing speaking, Meng Tian handed Li Xi a sheepskin full of words.

"Third, Bai Long and Zhao Sheng (Meng Tian's generals) took the guide and led 50,000 crossbow archers and 30,000 Qin crossbows to the designated place on the map to ambush." Saying that, Meng Tian also handed Bai Long a sheepskin full of words, "Qiang Yi (Qiang Diao's son) and Yang Hongxi (Yang Duanhe's son) led 50,000 cavalry to march to the grassland north of Yanmen Pass to wait. Meng Shan (a member of the Meng clan of the old Qin people, a general of Meng Tian) led 2,000 crossbow archers and 1,000 elite cavalry to ambush on both sides of Yinshan, and be sure to shoot and kill the Xiongnu Tanma who reached Yinshan and chased and killed the Tanma who returned close to Yinshan. ”

Meng Tian personally led 150,000 cavalry with Kunyue and other generals to transfer to Jiuyuan to Yanmen Pass. All the generals went out to order troops to carry out the order according to Meng Tian's general order.

Along the way, Kunyue admired Meng Tian's magic in using troops very much, and repeatedly said that he wanted to learn the art of war and battle formations from Meng Tian, and Meng Tian agreed one by one, saying that when he returned to Xianyang, he would choose the appropriate art of war and battle formations to teach the generals under his command.

Why did the descendants of many generals serve in the Mengtian army? By the way, at that time, many generals and officials sent their children to Meng Tian's army to learn Wen Taowu's strategy. Among them, Li Si's son Li You is also a disciple of Meng Tian, which shows that Meng Tian's popularity in Daqin is very good.

Mao Dun was ambushed by Meng Tian, and was defeated in the first battle, although his superiority over the Qin army's army had not changed, but the morale and battlefield advantage had changed.

Maudun was furious for a long time, and then he slowly calmed down, and he slept sadly all night before waking up. Hearing Tanma's report that Meng Tian's army had withdrawn to Yinshan, Tanma who made a detour to the past also found that Meng Tian's banner was hanging on the Jiuyuan Great Wall, and a strange array composed of the same chariots as yesterday was deployed under the Great Wall.

Therefore, Mao Dun left 100,000 soldiers and horses to protect the family and cattle, sheep and horses who went south with the army, pretending to be a million troops still looking for an opportunity to cross Yinshan to attack Jiuyuan, and personally led the remaining 600,000 troops to detour to the west, first sneak attack Yanmen Pass and then surround Longxi from behind.

As for what the plan of Maodun to sneak attack on Yanmen Pass will be, it will be broken down in the next chapter.
