Changyuan County is the northeasternmost county of Hongnong County, close to Henan County where Luoyang is located, the strategic location of Changyuan County is very important, just located in the throat of Hongnong to Luoyang, when the Tang Army attacked Luoyang, Changyuan County was arranged by the Tang Army as the largest grain and grass logistics center.

Li Shimin attaches great importance to the safety of grain and grass logistics, and ordered Shi Danai to lead 10,000 troops to garrison Changyuan County, and the material battalion of the Tang Army is located three miles east of Changyuan County, which is a barrier-type camp, covering an area of hundreds of acres, and 10,000 troops, half of which are stationed in the county and half are in the camp.

Changyuan County is a middle county, with a population of more than 3,000 households, the county order is surnamed Jiang, a native of Luoyang, the county is called Zhang Hongbang, a native of Hongnong County, and he is the Yang family introduced to Xu Shiji.

Zhang Hongbang is about 40 years old, his family has been poor since he was a child, but he is smart and studious, and he was favored by the Yang family 25 years ago, so he was allowed to study in Yang Xue, and deliberately cultivated him.

With the Yang family as the backstage, Zhang Hongbang embarked on the official career step by step, successively served as Gong Cao, county commander, and was recommended by Yang Su as the head of Hongnong County in the first year of the Great Cause, and later served as the Shaoqing of Sinong Temple.

In the ninth year of the great cause, he was implicated in Yang Xuangan's rebellion and was demoted to Changyuan County, after Wang Shichong ascended the throne, he was invited to Luoyang to serve as the secretary of Sinong Temple, but he did not go because of his illness.

In the morning, Zhang Hongbang was handling official business in the county office, and he was also very busy in the war in Luoyang these days, when a government official came in to report, "County Cheng, the son is here!" ”

Zhang Hongbang has a son and a daughter, his daughter is married, his son Zhang An is now studying in Yang, he is the pearl of his palm, he heard that his son is coming, he laughed and said: "Let him come in!" ”

After a while, his son Zhang An walked into his father's official room with an entourage, and Zhang An stepped forward and saluted, "Father is well!" ”

Zhang Hongbang nodded and asked, "How do you have time to come here for my father?" ”

"Back to the father, it was the head of the family who let the child come."

It was actually the head of the Yang family who asked his son to come, Zhang Hongbang was slightly stunned, and he glanced at his entourage. See that he is tall. He has a strong physique and powerful arms, not like a villager. He asked his son, "Who is this?" ”

Zhang An stepped forward and whispered a few words to his father, and Zhang Hongbang was suddenly surprised. It turned out that Sui Jun was coming, he got up and walked to the inner room, "You guys come with me!" ”

In the back room, the entourage stepped forward to salute, "Below is General Xu's personal soldiers, and on the order of General Xu, send a letter to Zhang Xiancheng." ”

After speaking, the entourage took out the letter and presented it to Zhang Hongbang, who knew Xu Shiji. He is the youngest general under Yang Yuanqing's account, only two or three years older than his son, young and promising. He led a large army to Changyuan County. Naturally, it was for the grain and grass materials of the Tang Army.

He opened the letter and read it, groaned and asked, "I don't know where General Xu is now?" ”

"Our army is now more than 20 miles away from the Forget Worry Post."

Twenty miles is not a long distance. Zhang Hongbang said: "That's it! I'm going to meet you, General Xu. ”……

Several people rushed all the way, and after half an hour, Zhang Hongbang rushed to the temporary camp of the Sui army, Xu Shiji personally greeted the big tent, he knew that Zhang Hongbang was also a high-ranking official of the imperial court, so he was very polite to him.

The two walked into the big tent and sat down, Xu Shiji ordered tea left and right, and then said apologetically: "I didn't expect to bother to make the king come in person, Shiji is ashamed!" ”

Zhang Hongbang saw that although Xu Shiji was young, he behaved calmly, spoke wisely, and had the style of a Confucian general, he secretly admired it in his heart, so he smiled and said: "General Xu doesn't have to be polite, now is an extraordinary period, when everything is focused on the overall situation, Zhang is a Sui minister, and his heart is naturally towards the Sui Dynasty, I will try my best to help the Sui army, I don't know what I can do for the general?" ”

Xu Shiji knew that he knew what he knew, so he was not polite, and said straight to the point: "We are here for the logistics of the Tang Army. ”

Zhang Hongbang frowned slightly, lowered his head and was silent, Xu Shiji saw that his face was embarrassed, so he smiled and said: "If Zhang Xiancheng is embarrassed, I will not force it." ”

Zhang Hongbang sighed and said: "It's not a secret, the Tang Army's grain and grass are heavily guarded, it is difficult to get in, I have only entered once so far, and I have to be searched, if I want to enter the camp to burn food, it is really difficult for me to help." ”

Xu Shiji shook his head, "Zhang Zhijun misunderstood, I didn't mean to burn grain, my purpose was to build momentum and force Li Shimin to retreat westward, of course, if I could cause a little loss to the enemy, it would be the best." ”

Xu Shiji also knew in his heart that Li Shimin left 10,000 heavy troops to guard the logistics camp, and it would be difficult for them to break through the enemy camp, but if they just created a crisis and bluffed, they didn't need Zhang Hongbang's help.

The key is that he wants to inflict losses on the enemy, and this time Changyuan County can't run in vain, at least to make a small profit, which requires Zhang Hongbang's full assistance.

Zhang Hongbang understood what Xu Shiji meant, and he smiled and said, "Then I don't know what kind of assistance I can provide." ”

Xu Shiji was confident, and said unhurriedly: "I want to ask the envoy to tell me about the specific situation of the Tang Army first. ”……

At night, the night shrouded the earth, and there were a few dark gray floating clouds floating in the sky, and a round of crescent moon passed through the floating clouds, making the earth bright and dark, but the front of the Tang Army's logistics camp was brightly lit, and hundreds of torches illuminated the front of the camp as if it were day.

Hundreds of Tang Army guards patrolled back and forth near the camp gate without slackening at all, and several patrols of more than a few hundred people patrolled within two miles of the camp, and no one was allowed to approach.

There is a hill that stretches for more than ten dozen miles in the south of the camp, called Huilonggang, the forest is luxuriant, the forest is dense, at this moment, 20,000 Sui troops entered the hill woods, and the soldiers rested quietly on the trees in twos and threes.

At the front of the hill, Xu Shiji stood under a big tree, looking at the Tang army camp in the distance, the Tang camp was huge, similar to Changyuan County, surrounded by a high wall barrier, there was a sentry every thirty steps, and the guard was very strict.

Standing on a high place, you can clearly see the huge camp tents in the camp, which store 200,000 stone grain and hundreds of thousands of loads of forage of the Tang army, as well as countless tents and ordnance.

Xu Shiji sighed slightly, tactically, of course, he wanted to destroy this Tang army camp, but strategically this camp must be retained, so as to lead Li Shimin's army to Hongnong County, if there is no logistics camp, Li Shimin's forces will inevitably go to Yingchuan County.

At this time, a black shadow ran at the foot of the mountain, and soon ran up the hill, and two soldiers brought the black shadow up, which was a confidant of Zhang Hongbang's family, and he came to deliver the letter, and he took Zhang Hongbang's token.

"My lord asked me to tell the general that Shi Danai, the commander of the Tang Army, is now in the county, and my lord asked, the specific time to do it."

Xu Shiji looked at the moonlight and said, "Please tell Zhang Yuanjun that it will be launched left and right!" ”

"I understand, I'll go back and tell my master!"

The family saluted, turned around and left, Xu Shiji looked at his back and walked away, and resolutely ordered: "Order the whole army to prepare for battle!" ”……

Due to the excessive storage of materials in the camp, there were not enough 10,000 soldiers to live, so the Tang army divided its troops into two routes, half of the 5,000 people were stationed in the camp, and the other half of the 5,000 people were stationed in the county seat.

Shi Danai is a Western Turkic nobleman, the full name is Ashina Danai, five years of great cause, the Western Turk Luo Khan was defeated by the Khan of Sheku, and Luo Khan took the rest of the army into the Sui Dynasty for refuge, Shi Danai also came with him, with 3,000 tribal troops under his command.

Li Yuan raised troops in Taiyuan, and Shi Danai defected to the Tang army, and his tribe became a Turkic force in the Tang army.

Shi Danai won Li Shimin's trust, and this time he was ordered to be the chief general of logistics, in charge of 10,000 troops, Shi Danai did not dare to be careless, and guarded the camp with all his heart.

At night, Shi Danai sat alone in the room and drank, drinking was his greatest hobby, if it wasn't for wartime, he could drink five or six catties at a meal, but now he didn't dare to drink more, and occasionally drank a few glasses.

This is also the reason why he is reluctant to live in the big camp, where alcohol is strictly prohibited, and living in the county seat is a little freer.

At this moment, a report from the soldiers came from outside the door, "General, Zhang Xiancheng has an urgent matter to see!" ”

"Hmmm! Let him in. ”

After a while, Zhang Hongbang, the county magistrate, hurriedly walked in, bowed down and saluted: "General Shi, the lower officials have something important to report." ”

"What's the matter?"

"General, I have a family member who just came from my hometown today, and he said that he found a Sui cavalry in the west of the county seat."

"Sui Jun?"

Shi Danai was taken aback for a moment, and hurriedly asked, "Where is it, how many Sui troops are there?" ”

"Twenty miles northwest of the county seat, there are about two or three thousand people."

Shi Danai had no intention of drinking, and his heart became nervous, the Sui army actually appeared in Changyuan County, which was obviously coming for them, but there were not many people, which made his heart relax a little, and he groaned and asked, "When did you find out about the Sui army?" ”

"The family had just arrived, and when they found the Sui army, it should have been in the evening."

Shi Danai became anxious, if so, the Sui army should have arrived, at this moment, there was a rush of running outside the door, and a soldier reported in panic: "General Qiyu, there are about 3,000 Sui troops rushing to attack the camp, in the northwest corner of the camp, the Sui army uses rockets, it is very critical." ”

Shi Danai stood up and shouted, "The army will be gathered immediately, and I will go out of the city with me to rescue the camp!" ”

Zhang Hongbang nodded silently, and an imperceptible sneer flashed in his eyes......

At the beginning of the city gate, Shi Danai took the lead and led 5,000 Tang troops to gallop towards the camp five miles away, and the other party only had 3,000 cavalry, which was consistent with Zhang Xiancheng's intelligence, which was obviously the Sui army to attack the camp.

This is actually a psychological hint, Zhang Hongbang first told him that there were two or three thousand people, and then the battalion found that there were three thousand Sui troops to attack, under this double hint, it is easy to think that the Sui army is only three thousand, so that Shi Danai lost his vigilance.

In the dark night, the five thousand Tang troops rushed all the way, the road was very familiar, and they could reach it in a quarter of an hour at a distance of five miles.

After marching three miles, there was a small river several feet wide in front of it, and there was a wooden bridge over the river, and in the distance, the black swarthy wall of the camp could already be faintly seen.

The team slowed down and began to cross the bridge one after another, less than half of the team crossed the bridge, at this moment, only to hear the sound of a bang, and suddenly ten thousand arrows were fired dozens of steps away, and the arrows were like a storm, shooting towards the Tang army who was crossing the river
