Tibet

[This chapter was missed, Lao Gao is really sorry! 】

===

For several days, Zhangye City was immersed in the joy of family reunion. Although they lost their property, their property was not as important as the rescue of their relatives.

In the large tent of the Chinese army in the military camp, the preparations for the attack on Dadou Bago are being carried out nervously.

"The strategy of Dadou Bugu is of great significance. Once we capture Dadou Bago, it will be equivalent to putting a dagger on the back of the Tibetan army, forcing the Tibetan army not to dare to launch an offensive eastward, and the security of Jincheng County will be fully guaranteed. Assure."

In the Chinese army's tent, Li Ye stood in front of the sand table and introduced the current situation to more than a dozen generals. "Shang Jiezan's most urgent thing now is to open up the passage between Shanzhou and Lingzhou. He is not very interested in other Longyou areas." Eager, and Jincheng County happened to be between Shanzhou and Lingzhou, it became the biggest obstacle to the Tibetan army.

In fact, Ma Chongying also launched the battle against Jincheng in order to open up this lifeline connecting Hehuang and Lingzhou. When it was Shang Jiezan's turn, even if he denied Ma Chongying, he could not avoid Jincheng County. "

Pei Xiu said solemnly: "If we win the battle and pull out the valley, the Tibetan army will not dare to act rashly."

"That's right!"

Li Ye smiled and said: "There is a thief squatting in front of your house, how can you rest assured when you go far away? Of course, we are not thieves, it is just a metaphor."

Everyone laughed. Li Ye handed the wooden pole to Pei Jun next to him and smiled at everyone: "Pei Changshi guarded Dadou Bugu for ten years when he was young. Let him introduce Dadou Bugu to everyone."

Everyone was immediately surprised. It seemed that an elegant civil servant had been guarding the Great Battle of Bugu for ten years.

Pei Jun took the wooden pole and said with a smile: "Your Highness is a bit exaggerated. I have been a defensive envoy for the Great Battle for ten years, but it does not mean that I stay there every day. I only stay there when the war between Tang and Tibet is tense." There, I was still in Zhangye most of the time, but I do know Dadou Bago better, so I’ll give you a brief introduction.”

Pei Jun pointed to a rift valley on the sand table and said: "This is the Dadouba Valley. This canyon is really a line of sky in the Qilian Mountains. It is very long and narrow, with thousands of twists and turns. On both sides are cliffs thousands of feet long. It is seventy miles long and wide. From two feet to more than a hundred feet, there are several underground rivers in it, which are important water sources in the valley.

There are three relatively spacious places in the entire valley, located at the mouth of the valley, in the middle of the valley, and at the end of the valley. Both the Tang and Tubo armies built military cities here, which were built with stones and repaired repeatedly. attack.

But to capture Dadou Bagou is to attack these three military cities. To capture these three military cities is to capture Dadou Bagou. The most critical one is the Qilian Military City in the middle, which is also the largest and most difficult to attack. "

After the discussion was over, everyone dispersed, but Li Ye was still looking at the military city in Dadou Bagou.

Pei Jun smiled slightly and said: "In the 16th year of Kaiyuan, your grandfather led an army of 10,000 to attack Dadou Bago. He captured Dadou Bago without losing a single soldier. It was this battle that established his position in Hexi. .”

"How did grandpa do it?" Li Ye asked enthusiastically.

"Cut off the water!" Pei Jun spit out the secret of his father Pei Fang's victory. It was very simple, just two words.

Five days later, Li Ye personally led an army of 20,000 people to the mouth of Dadou Valley and set up camp a few miles away.

Although it was very difficult for the Tang army in Hexi to fight for the big battles and they had to pay thousands or even tens of thousands of people each time to win, Li Ye did not intend to pay such a heavy price. He had a powerful offensive weapon, which was Kerosene and heavy armored infantry.

As soon as the 20,000 Tang troops arrived, they were discovered by the patrol. Alarm bells immediately sounded in Dadou Bagou, and thousands of soldiers guarding the valley became extremely nervous.

There seemed to be a total of ten thousand people in Dadou Bugu, both inside and outside the valley. Most of them were stationed outside the valley, with 7,000 troops stationed there. Even if the Tang army came out of the valley, they would be intercepted by these 7,000 troops.

Although the valley is seventy miles long, it is true that too many troops cannot be deployed. Very few troops are in the military city. The other troops are building fortifications on the official road in the valley to cooperate with the castle for defense.

The army rested overnight, and in the morning of the next day, General Nan Jiyun personally led five thousand people into the canyon.

The five thousand people include one thousand heavy shield troops, five hundred refueling troops, five hundred Modao troops, two thousand heavy crossbow troops and one thousand spear infantry. In addition, there is a logistics transport team of two thousand people.

The army entered the canyon, the originally bright sunshine disappeared, and the valley became dark.

The general, Nan Jiyun, was riding on an extremely powerful Dawan horse. The horse's coat was as bright as coals, without a stray hair. This was the reward he received for his first meritorious service in the battle of guarding Chang'an. It was a gift from King Bukhanna. A bloody horse for Li Ye.

The tall Nan Jiyun was riding on this war horse, looking even more majestic and majestic. This was his first time coming to Dadou Valley, so he was extra cautious.

There was no battlefield in the valley, and there was no cavalry. At the front were three hundred heavy-shielded soldiers, each of whom raised a large shield and marched in line.

Behind the heavy shield army are five hundred refueling soldiers. This is a unique branch of the Helong Army. Their task is to spray fire oil.

Each soldier carries a ten-pound kerosene bag and a push-pull pump, made of bronze or brass. The kerosene in the leather bag is pumped into the pump through a copper pipe, and then pushed out. Initially, a sheep was used. A tube was used to extract the small intestine, but the effect was not good. After improvement, a hard copper tube was used, and the tube could be sprayed to a distance of seven to eight feet.

Of course, the copper pipes in the Tang Dynasty were not weapons-grade copper pipes. They were made by beating red-hot copper plates into thin sheets and then rolling them up, and then filling the gaps with copper water. They were relatively rough and could not be used as gun barrels. The gun barrels must be Cast in one piece with a mold.

In addition to the kerosene bags, each refueling soldier also hung five kerosene pottery bottles on his waist. They looked like plum vases, had thin skin and large fillings, and contained two kilograms of kerosene.

After pushing forward for about a few miles, we should have reached the first military city.

Suddenly there was a shout from the front, and stones came like raindrops. More than a dozen soldiers with heavy shields were caught off guard. They were hit in the head by stones and fell to the ground immediately, with their heads bruised and bleeding.

From above, dense arrows were shot. The Tubo people also had bows and arrows, but the range was not far. It was inconvenient to throw stones in the military city. Using bows and arrows from a high position would be more effective.

There is indeed an open land in front, covering an area of ​​about dozens of acres, mainly sunken to the right. There is a mound below, and there is a small military city on the mound, covering an area of ​​only one acre.

For the Tang army, this could not be called a city, but a garrison.

However, on the mound where the military city was built, the overall height was about 60 feet. Dozens of Tibetan soldiers stood high and shot arrows downwards. The height was equivalent to 60% of a building.

Sure enough, as Pei Jun said, there is no door at all. You can only climb up the hillside first and use an external ladder to climb up.

Below the military city, the Tibetan army built a fortification about one foot high with mud bag belts. Hundreds of Tibetan soldiers threw rocks behind the fortification, and the high mud bags blocked them.

Nan Jiyun sneered. At first glance, he looked like an inexperienced recruit. He was actually hiding behind the wall. Do you think the bows and arrows were all shooting flatly?

Nan Jiyun immediately shouted: "Fire the heavy crossbowman!"

Five hundred heavy crossbowmen lined up in ten rows, adjusted to look at the mountain, raised their crossbows and threw them a hundred steps away, 'Brush! 'Five hundred heavy arrows rose into the sky and were shot at a sixty-degree angle. The arrows flew into the sky and fell in a parabola. They fell like raindrops on the group of Tibetan soldiers. Although these soldiers were labeled as Tibetan soldiers, they were actually They were all from Tuyuhun. They were all herdsmen before and were recruited into the army. Although they had military training, they had never fought against the Tang army.

They held simple shields in their left hands and threw out rope stones with their right hands. Suddenly, a powerful rain of arrows from the Tang army came. Even if they had shields, it was of no avail. The shields were hit and shattered. Hundreds of soldiers fell to the ground after being hit by arrows. Wailing, the other soldiers rolled and crawled and hid behind the mud bags. Only at this angle, the Tang army's arrows could not reach them.

Nan Jiyun waved his hand, and three hundred heavy-shield soldiers raised their shields and ran quickly. Taking advantage of the Tang army's arrows to suppress the opponent, they rushed behind the sandbag wall in one breath.

They cooperated tacitly and dragged the sandbags to the ground. Seeing that the situation was not good, the leader of the army shouted a few times, and hundreds of Tibetan soldiers ran wildly and retreated deeper into the valley.

The Tibetan soldiers on the official road fled, and there was still a stone castle left. Nan Jiyun ordered: "Throw kerosene bottles and attack!"
