In fact, the Mongolian army is the master of strategy. The harsh environment of the Mongolian plateau makes them tough and cunning.

Due to the lack of food, they often need to hunt for survival resources. Generations of battles with wild beasts have formed the innate combat skills of Mongolian soldiers.

In their view, war is also a kind of hunting, except that the prey becomes a man. The use of stratagem to obtain booty such as land, property, women and slaves at minimal cost was clearly a priority.

In fact, in the process of besieging Hengyuan Fort, the Mongolian army has always been full of stratagems, but it did not succeed.

For example, due to the heat, some people in the Mongolian army camp began to vomit and diarrhea, and they tried to carry the sick and dead into the mountains, but they were repelled by artillery fire.

The secret Huoli also sent spies to sneak into the mountains at night to sabotage, but they were discovered in front of Wanjiabao. He also considered a plan to attack flooding by fire, but he also gave up because he did not meet the conditions.

Zhu Zhu'er's plan was to send a small force over the mountains to attack the rear of the Thunderbolt army. This is to imitate the Three Kingdoms when Deng Ai bypassed the Jianmen Pass and attacked Shu from Yinping Road.

How could the generals of the Mongolian army who were waiting for the secret of this scheme not know? When it comes to roundabout attacks, the Mongols can be called masters.

With the help of the mobility of cavalry, the Mongolian army often carried out long-distance raids in the enemy's territory, and was a master of large depth and penetration.

The Great Khan of Ögedei was according to Genghis Khan

The plan of "Han belly" is to send a tow mine to force it

"Borrowing" the Southern Song Dynasty hit the Jin State hard. In the process of attacking the Southern Song Dynasty, the Mongolian army even passed through the harsh climate and steep terrain of the Tibetan region several times to destroy the Dali Kingdom, forming a siege of the Southern Song Dynasty.

Meng Ke Khan focused his strategy on the Sichuan battlefield, but also in order to bypass the heavily defended Jinghu and Lianghuai battlefields, and go down the river to the hinterland of the Southern Song Dynasty to drink horses and Lin'an.

Of course, the Secret Fire has also considered using it against the Thunderbolts

The plan of "Han belly", but the hinterland of the Perak army, Jiguan Mountain, is extremely steep and densely forested, and it is impossible to march at all.

And even if you enter the mountains, you obviously can't get to Wanjiaping, where the headquarters of the Thunderbolt Army is located, through Wanjiabao.

I heard that the defenders of Wanjiabao are much smaller than those of Yokohara Fort, but its terrain is more easy to defend and difficult to attack, and it is obviously not something that a lightly armed partial division can overcome.

"My lord, the Thunderbolts are nothing more than firearms. Although there are dozens of villages in Jiguan Mountain, the only ones that can produce firearms are Wanjiaping and Liuliba. This cockscomb mountain and the villain's perennial living Heming Mountain are back-to-back. My subordinates said that there is a small road leading to Liuliba, and although the road is extremely dangerous, it is still possible to try. Seeing that the secret is in the fire, Zhu Zhu'er said.

If it were an ordinary attack, the secret fire would definitely refuse this suggestion, and this sneak attack seemed reliable but was actually very risky.

But the situation is stronger than people, and the current Mongolian army has no good strategy for Hengyuan Fort, and the only way to use it is to dig tunnels.

Not to mention that the defenders of Yokohara Fort must have a way to deal with it, and it will take more than half a month to dig into the fortress just by tunneling.

Even if Yokohara Fort is successfully defeated, the mountain Wanjia Fort is also a difficult bone to gnaw. When there is nothing to do, the secret one's plan for Zhu Zhu'er in the fire is like a treasure, just like a drowning person encountering a floating straw, no matter what, you have to catch it to see if you can save your life.

The secret Huoli ordered the elite to be drawn from the army, and Zhu Zhu'er led the way to act according to the plan. In terms of the scale of the sneak attack on the partial division, the secret one Huoli had hesitated, the number was small and the strength was weak, even if the sneak attack was successful, it would be quickly counter-killed, and it would not have any effect on the war.

There are too many people to hide their whereabouts, so that the other party is prepared, and then the sneak attack will turn into a frontal attack.

After many calculations, he decided to transfer five hundred elite combat forces. Among the five hundred were 100 Mongol archers, 100 Mongol Han soldiers, 200 new annexes, and 100 able-bodied people.

Needless to say, the Mongolian soldiers were brave and good at fighting, and the 200 new annexes were also the elite who were selected from thousands of people to be good at mountain warfare, and their combat strength was not below that of the Mongol archers and the Mongol Han army.

As for the hundred people, it was used to help clear the way and carry heavy loads in order to preserve the fighting power of the soldiers.

Zhu Zhu'er led the people to Dayi City first, and then turned from Dayi City to Heming Mountain. Although this road was 200 miles, it took only three days.

In addition to the smooth road, it is also due to the fact that all horses are ridden. The soldiers and men of the new annex army could not ride horses, so the Mongols chose many docile mules and horses for them to ride, and tied them firmly to the saddle to prevent them from falling off their horses.

When he arrived at Heming Mountain, the road became more and more difficult to walk, so Zhu Zhu'er sent people to send the horses back, and he led people to start marching towards Jiguan Mountain.

Because the original sheep intestine trail has been barren for a long time, it has long been indisputable, and the guide who leads the way often gets lost, often goes off the rails or even goes to the cliff where there is no road.

It's summer when the trees are overgrown, and you need to move forward while clearing the wasteland. The people slashed with great force, and it took several knives in a day to cut a road that could only accommodate one person.

In addition, the road is steep, and there are poisonous snakes and leeches along the way, so the team of 500 people can only walk a few miles a day, and only half of the distance is covered in three days.

What's worse is the supply problem, the food is enough, the key is that the consumption of water is too large. Both the Mongols and the Mongol Han army lived in the cool north, and could not stand the hot and humid climate.

They walked through the dense and impermeable woods, soaked with sweat, and drank water like oxen, and after three or five strokes they had consumed their drinking water, and had to send people to the mountain streams to fetch water.

What's worse is that it is a high-intensity march during the day, and it is not good to sleep at night when it is bitten by mosquitoes. After three days, many soldiers were exhausted and their eyes were scattered, and many of them were already weak or even collapsed because of heat stroke and diarrhea after drinking raw water.

Seeing this, Zhu Zhu'er asked the Mongolian centurion to return the same way with the soldiers who were not accustomed to the water and soil.

Just this walk, nearly half of the people walked. He counted the numbers, and now there were one hundred and forty new annexes, eighty people, and more than forty Mongol soldiers.

With fewer men, the speed of the march increased considerably. Two days later, Zhu Zhu'er and his 260 men arrived at a mountain stream.

Wade through this creek and climb over a mountain, and tomorrow you will reach the boundary of Liuliba. At this time, it was the afternoon when the sun was scorching, Zhu Zhu'er and his gang walked through the dense forest for most of the day, and they were already thirsty and hot.

While they were burying their heads and drinking, many iron bumps flew down from the dense forest above the stream. The sharp-eyed soldier saw the iron bumps falling, and fled as he found them and exclaimed in surprise.

At this time, Zhu Zhu'er, like most of the soldiers, was burying his head in drinking, and when they raised their heads and saw clearly that the falling thing was a grenade, they all pulled out their feet and fled, but there was no time.

After a series of violent explosions, the entire creek was shrouded in smoke. The smoke cleared, the bottom of the ditch was littered with dead and wounded, and the stream turned red.

The explosion was followed by shouts of killing, and from the dense forest above the stream, many sturdy men with knives came out of the dense forest and ran towards them.

The Mongolian army, who had just eaten a grenade, obviously had not come to their senses, they did not expect that they would also be bombarded by firearms in this barren mountain and wilderness, and where would they resist at this moment, they all drilled all over the forest.

It's just that this dense forest is full of thorns, and it can't run at all, and it won't take long to catch up. With the exception of a few who resisted and were killed, most of the Mongol army was taken prisoner.
