As a Chinese, Comrade One Piece also learned some famous battle examples through study after enlisting in the army, such as the Warring States Bai Qikeng killed 400,000 Zhao troops, the Xiongnu 400,000 Bai Dengwei Liu Bang, Xishui Xie An broke 800,000 former Qin troops, and the 800,000 Western Xia army attacked the Song Dynasty and so on.

But Dumu has the legendary hero Xue Rengui who came out of the mouth of his eldest brother.

Xue Rengui's almost mythical legend made his blood boil when he listened to it, and his heart was surging and heroic.

These stories make people inevitably imagine a majestic general, a hero of the world leading thousands of troops and horses, like a rainbow, mighty and powerful to smash the Yellow Dragon!

Flying sand and rocks along the way, shocking the world and crying ghosts and gods, people are proud of the courage of our Chinese people from the bottom of their hearts.

What makes people sigh is that this commanding and victorious general suffered a miserable defeat in the Battle of Dafeichuan because his subordinates did not obey orders and did not cooperate well with the battle plan.

The Battle of Dafeichuan made a generation of famous generals Xue Rengui encounter the Battle of Waterloo, and the Battle of Dafeichuan was also the biggest defeat since the founding of the Tang Dynasty, and the 100,000 army was surrounded and annihilated by 400,000 troops of Tubo!

It is said that Xue Rengui led the army through Shanzhou (the western capital, now Ledu, Qinghai) to Dafeichuan in Hunan, Qinghai.

Xue Rengui knew very well that the Tubo army had many generals and a wide range of soldiers, and they waited for work at ease, and the Tang army had to fight quickly to win the battle.

Wuhai (now Kara Lake) is far away, it is inconvenient for heavy vehicles and horses to travel, and it is easy to lose fighters, so Guo Beifeng led 20,000 people to guard the baggage, grain and grass, so that it can be placed on the Dafei Ridge with danger, and build fortifications, making it a frontier position that can be attacked, retreated, and defended.

Subsequently, Xue Rengui immediately led the main force and rushed lightly. The two armies fought at Hekou (present-day Maduo, Qinghai). The Tibetan army was caught off guard and defeated, with many casualties and more than 10,000 cattle and sheep.

Xue Rengui took advantage of the victory to occupy Wuhai City and waited for backup. However, after Guo Zhifeng relied on the famous general Guo Xiaoke, he refused to accept Xue Rengui's control, led the rear team to advance without authorization, and failed to meet the coach in time.

The Tubo army seized the fighter plane and invited more than 200,000 people to attack its troops, Guo Beifeng could not resist the enemy, and his baggage, grain and grass were lost. Xue Rengui was forced to surrender to Dafeichuan.

In August, the Tubo army, under the command of Qinling, forced the Tang army to fight a decisive battle with more than 400,000 troops.

Xue Rengui had no danger to rely on, and there was no food and grass to supply military supplies, so he was defeated and suffered heavy losses, and Xue Rengui and others "made peace with Qinling and returned".

This was the biggest defeat in foreign warfare since the founding of the Tang Dynasty. It is also the biggest failure of Xue Rengui's life.

The comrades of the navy used this battle to induce Comrade One Piece to analyze, although this battle was called the "Battle of Dafeichuan", in fact, the victory or defeat was decided in Wuhai.

Wuhai (Tuosuo Lake) is the main traffic route on the Qinghai-Tibet Plateau since ancient times, Princess Wencheng passed through here when she entered Tibet, and the altitude here is about 4,000 meters.

Xue Rengui had already gained the opportunity in this battle, but Guo Beifeng's unauthorized actions caused the Tang army to turn from victory to defeat. In fact, Guo Beifeng's unauthorized actions were an important reason for the defeat of the Tang army.

One: geographical factors, altitude sickness. The disease also weakened the combat effectiveness of the exhausted Tang army.

Xue Rengui's troops experienced a rapid advance from low altitude to high altitude. The Tibetan Plateau itself is a plateau with complex topography and occasional undulations.

The starting point of the Tang army was Shanzhou (present-day Ledu County, Qinghai Province), which was located in the Hehuang Valley at an altitude of about 2,300 meters, and the possibility of a high mountain (original) reaction at this altitude was very small.

At an altitude of more than 4,000 meters above sea level, a considerable number of people will have alpine (original) sickness, and there is a risk of acute pulmonary edema and heart disease, while most people will have dizziness, headache, palpitation, diarrhea, and fatigue.

What's more, Xue Rengui commanded the troops to "light and sharpen the road", that is to say, quickly advancing from the low altitude to the higher altitude area, lacking the necessary time to adapt to the plateau environment, and the physical exertion must be very large, so the consequences will be more serious.

2. Strategic intent. Siege Wei to save Zhao, the purpose of which is to occupy Lhasa (i.e., Lhasa).

The Tang army "took Luo Su as the name of the division, and perhaps had the meaning of going straight to the Yellow Dragon after victory." Before the war, the Tang side was full of ambition and boldly went deeper.

At that time, he was famous on the battlefield and was also known as the mythical figure of "Three Arrows to Set the Heavenly Mountain", and Xue Rengui, the general of the Right Weiwei, was edicted to be the general of the march of the Luosa (i.e., Lhasa) Road.

The right guard foreign general Ashina Daozhen and the left guard general Guo Zhifeng were deputies, leading 50,000 troops to crusade against Tubo, so that Tubo could be surrendered again, and once the crusade was successful, he would send Tuyuhun to flee to the Khan Nuo Hao bowl and return to his hometown.

The 200,000 troops who invited Guo to attack Guo Beifeng should also be mostly Tuyuhun troops (Tuyuhun has an absolute force in Tuyuhun country).

On Qinling, if the domestic army is transferred to the rescue, it will definitely be too late, and it must pass through Wuhai, Xue Rengui has already waited for work and is ready for battle, and the Western Regions Army and Ashina Zhong and Ashina are all supported there to fight.

On Qinling's decision, judging that Xue Rengui personally led the main force to attack Wuhai lightly, and the grain and grass were bound to be insufficient, so he quickly dispatched the Tuyuhun army to invite the Tang army to attack the Tang army's grain, grass and baggage, and cut off the Tang army's reserve supply.

And the Tuyuhun army may have come from the two directions of Fuluochuan and Fuqicheng, bypassing the Wuhai guarded by Xue Rengui.

In the battle in the snow mountain, supply is the first life, and the supply is not good, so Xue Rengui can only withdraw from Wuhai.

In this way, the Qinling calmly recovered Wuhai, and then successively gathered the men and horses of various departments, and the 400,000 troops finally assembled in Tubo also came with reinforcements one after another (so the Qinling did not force Xue Rengui to fight a decisive battle until August).

In this battle, both sides took advantage of the situation, avoided the real and made the false, attacked the weakest link of the other side, and were very clever in tactics and use of troops.

However, Tubo adapted to the climate and environment of the plateau, and the army also had an absolute advantage (400,000 vs 50,000), and at the same time, the Qinling Tomb made correct strategic deployment with the help of Tuyuhun's strength in time, so it achieved the final victory.

Xue Rengui arranged for Guo Beifeng to carry the baggage to defend the danger, and then lead the baggage to set off to join Xue Rengui after Xue Rengui broke the enemy's army, if Guo Beifeng carried the baggage and defended the enemy attack before, he could rely on the fortifications to resist the enemy and support until Xue Rengui came back to defeat the enemy;

If Guo Beifeng led his baggage to converge after the battle in front of Xue Rengui, then when the enemy attacked Guo Beifeng, Xue Rengui could lead his troops to support Guo Beifeng in time and defeat the enemy army.

However, Guo Beifeng was dissatisfied with Xue Rengui's control, acted without authorization, and led the grain and grass to set off in advance, resulting in the attack of the Tubo army, Xue Rengui was fighting in front and could not come to support.

On the one hand, the plateau climate has weakened the Tang army, and on the other hand, if you continue to advance, the environment will be even worse for the Tang army, the glacier and snow area, the march is difficult, and Xue Rengui cannot fight all the way to Lhasa without the grain and grass baggage.

Guo Beifeng did not obey the general's order to transport his baggage in advance, and at this time Xue Rengui was fighting at the mouth of the river and Wuhai, and he had no time to come back to rescue.

On Qinling seized the opportunity of Guo Beifeng's mistake and sent a large army to break Guo Beifeng's department, the Tang army lost its grain and grass, which aggravated the altitude sickness, Xue Rengui could only lead the army to "retreat to Tun Dafeichuan", the Tubo army came to attack, and the Tang army was defeated, but in view of the combat effectiveness of the Tang army, the Tang army had to make peace with Xue Rengui.
