Not long after, there were soldiers in the yard reporting: "Report to the Commander-in-Chief, the soldiers are here!"
"Bring him in!"
The soldiers led the messenger into the room. The messenger knelt down on one knee and saluted, "Sent by General Yao, I am here to report to the Governor!"
"Is there any urgent military situation?" Guo Song asked.
"We found that the Tibetans increased their troops in large numbers in the Dadouba Valley, and a small team of scouts appeared at the entrance of the valley."
After saying that, the messenger presented Yao Jin's letter to Guo Song. Guo Song took the letter and read it. The letter said that Tubo sent a large number of troops to Dadou Bugu. It is estimated that the number of troops is no less than 10,000. It is likely that it has been sent to Dadou recently.
The attack on Taniguchi will be launched in a few days, and I hope Zhangye City will also be on alert.
Guo Song put away the letter and asked again: "Do Tibetan spies appear frequently?"
The messenger hurriedly said: "To inform the Governor, Tibetan spies appear every day, up to four times a day, which has never happened before."
"How did you know that the Tubo troops in the valley had increased?" Guo Song asked again.
"A few days ago, several Qiang herdsmen who went to Hehuang to exchange for salt came out of the Dadouba Valley. They are Qiang people from the Black Mountains. They came specifically to tell us that the Tibetans had increased their troops in the Dadouba Valley."
"Montenegro?"
Guo Song suddenly felt a little dazed. He remembered that he practiced archery at Xiutu Lake many years ago and lived with him. Wasn't it the Montenegro? There were also Sister Ying and Chief Pu, but he had forgotten them.
In fact, Guo Song has not forgotten it. In fact, he has been busy since he came to Ganzhou. He didn't even have time to stop and take a breath. He had no chance to think about the past.
Guo Song suppressed the surging thoughts, calmed down and said to the messenger: "Go back immediately and tell General Yao to be on high alert, and I will immediately send more troops to the mouth of the valley."
.........
Early the next morning, Guo Song's son Yang Miao and the heavy armored infantry commander Kang Bao led the heavy crossbow army and Mo Dao army to the Bagokou of Dadou for reinforcements. At the same time, he ordered Zhonglang General Zhang Tuo to lead two thousand cavalry to protect the heavy crossbow army and Mo Dao army.
The sword army moved forward, and this increase in troops increased the Tang army at Bagukou of Dadou to 9,000.
Dadouba Valley is located 120 miles southeast of Zhangye. It is a valley connecting the Hexi Corridor and the Hehuang area. It is also a large gap in the Qilian Mountains that stretches for thousands of miles. The widest point is tens of miles long, and the narrowest point is only
More than a hundred feet long, it has been a shortcut for Tibet to attack the Hexi Corridor since the Middle Tang Dynasty.
After the Anshi Rebellion broke out, the Tang Dynasty had no time to take care of the Western Regions and mobilized a large number of troops from the Western Regions. Tubo and Uighurs took advantage of the situation and moved in, causing the Tang Dynasty to lose large areas of territory in the Western Regions one after another. Dadou Bago was once occupied by Tuyuhun. In order to compete for the Hexi Corridor,
A war broke out between Tuyuhun and Shatuo more than ten years ago. As a result, the 30,000 Tuyuhun army was wiped out, and the Shatuo army also suffered heavy casualties.
The result of this battle was that the fishermen benefited. The Tang army controlled the entire territory of Ganzhou, and the Shatuo army retreated to Suzhou. The Tuyuhun people also gave up part of their occupation of Ganzhou and retreated to the Dadouba Valley. The Tang army established at the entrance of the valley.
We arrived at Tuniubao Military City and stationed 500 troops.
Currently, there are 3,000 troops garrisoned at Badou Bagukou, led by General Yao Jin. In order to prevent the Tibetans from taking advantage of the Ganzhou Army's northward movement to attack Zhangye, the Tang Army was particularly vigilant during this period.
At dusk, Yao Jin led dozens of cavalry to patrol in front of the valley entrance. He had received reports from the Qiang herdsmen a few days ago that a large number of Tibetan soldiers had entered the Dadou Valley. The Tibetan army in the valley was close to 10,000 people.
Of course, Yao Jin also knew that the natural conditions in the valley were very harsh. Snowfall was common in June and it was not suitable for military garrisoning. Normally, it would be enough to station more than a thousand people. If the number increased to 10,000, it was obvious that the army was targeting Ganzhou.
"General, I haven't seen any Tibetan spies today. It's a bit strange!" a captain said in a low voice.
Yao Jin agreed, "It is indeed a bit strange, but things are abnormal and there will be major changes. Brothers must be vigilant tonight and be ready for battle at all times."
"General, what you mean is that the Tibetan army will attack us tonight?"
Yao Jin nodded, "It's very possible!"
........
As night fell quietly, the Tang army began to increase troops to Tuniu Fort. Tuniu Fort could garrison 500 soldiers in peacetime and 1,000 soldiers in wartime. The military fort was located high up, blocking the only way in and out of the valley.
Of course, the Tibetan cavalry can forcefully rush out of the valley, and at most they will have to pay some casualties from arrows. But the question is, what about the logistical supplies? If the nail of the Tuniu Army Fort is not removed, the Tibetan army's logistical supplies will not be able to survive.
Come on, without logistical supplies, the Tibetan army will still collapse without a fight.
The Tang army's camp was stationed behind Tuniu Fort. When the Tibetan army attacked Tuniu Fort in a large scale, the Tang army would continuously reinforce the fort from behind.
At the first watch, dark figures appeared at the entrance of the valley. About two thousand people appeared at the entrance of the valley. Now it is impossible to distinguish the Tuyuhun people from the Tubo people. Their equipment and military uniforms are exactly the same.
In fact, Tubo has completely controlled the Tuyuhun people. In the past, only the head coach was a Tubo, and the Tuyuhun people still formed their own army. It was easy for conflicts to arise. Now, all ten leaders are Tubo people. This has fundamentally controlled the situation.
Tuyuhun soldiers.
Of course, the treatment and equipment have also been improved, and the distinction between the two is no longer as clear as before, but one thing has never changed. In any war, the Tuyuhun people take the lead.
The two thousand Tubo soldiers who attacked Tuniu Fort tonight are still Tuyuhun people.
A Tubo captain loudly said to the five hundred soldiers: "According to the rules, the first person to board the castle will be rewarded with a thousand sheep, and the other soldiers who board the castle will be rewarded with a hundred sheep!"
The path to attack Tuniu Fort is very narrow and cannot accommodate a large-scale attack by soldiers. Since it is a sneak attack, five hundred people are used to lead the attack. Once the five hundred people attack Tuniu Fort, other soldiers will attack together.
Five hundred soldiers carried simple siege ladders. They wore leather armor and leather helmets, and held shields and short swords. This was a characteristic of the Tubo army. Most of the infantry used short swords. This also affected the Tuyuhun army, which did not use long weapons.
When the two armies are fighting, they like to fight in close combat and give full play to the advantages of short weapons. However, if they are cavalry, they use eight-foot-long short spears.
The armor of the Tubo army is the famous chainmail, but it is only the equipment of the most elite Zanpu direct guards. Ordinary soldiers can only use leather armor. Pig iron production is a symbol of national strength. The annual pig iron production of the Tang Dynasty was two
One million catties, Tubo is still far behind in this regard.
"The time has come, let's go!"
Five hundred Tibetan soldiers, led by a 500-man commander, marched towards the mouth of the valley. A bright moon hung in the sky, filling the ground with silvery light. They could see for miles. The Tubo army was already faintly visible under the moonlight.
I saw the Tuniubao military city two miles away.
At this time, a thousand soldiers of the Tang Army were already waiting in the castle. The scouts of the Tang Army had discovered that the Tibetan troops were gathering at the mouth of the valley. The enemy would definitely attack tonight.
The soldiers of the Tang Army were lying in ambush at the top of the city with crossbows in hand. Only a few soldiers of the Tang Army were pretending to be lazy and walking around the top of the city. The Tubo people were suspicious. If they saw any flaw, the attack tonight would be stopped.
Half an hour later, countless black shadows appeared at the foot of the mountain and began to climb up silently. The Tuniu Army Fort was built on a low hill more than ten feet high. The military fort itself was only two feet high, but the mountain was more than ten feet high.
Qiu made the castle take advantage of its commanding position.
Yao Jin stared sharply at the Tibetan soldiers below. They had gradually climbed up the hill. He quickly estimated in his mind that they could shoot three rounds.
"It's ready to launch!" Yao Jin gave the shooting order.
'Bang! Bang! Bang!'
Suddenly there was a rapid bang on the top of the city, and a thousand soldiers stood up at the same time, raised their crossbows and fired at the enemy soldiers.
Just like a sudden mountain rain, the Tubo soldiers were caught off guard. They fell down one after another with arrows and screamed miserably. More than a hundred people in front were killed by random arrows. The Tibetan soldiers behind were frightened and fell down one after another.
On the hill, I dare not move.
This was an instinct to defend against danger, but it gave the soldiers of the Tang Army time to wind up their strings a second time. The five hundred captains had been killed in the first round of arrows. Several centurions did not know how to advance or retreat, and turned back to look into the valley.
.
They saw torches burning in the valley, which was a signal for them to retreat. They immediately shouted: "Retreat!"
But just as they stood up to escape, the second round of crossbow arrows from the Tang Army's soldiers roared in. Hundreds of soldiers were hit by arrows and rolled down the hill. The soldiers behind them fled into the valley desperately, and escaped dozens of steps. The third round of crossbow arrows from the Tang Army's soldiers came.
Attacked again, leaving more than a hundred corpses behind, and less than two hundred people remaining fled into the valley in panic.
There was a cheering sound on the top of the city, both cheering and ridiculing. The Tubo commander was so angry that he was furious, but he had no choice but to swallow the bitter fruit of a failed sneak attack.
