Deng Yulong said with a smile: "If you want to sneak attack, you must be surprised, now it is just night, the enemy army is not tired, if you go to sneak attack at this time, what do you think is the probability of success?" ”

In ancient times, there was no such thing as "probability", it was Deng Yulong who said it a few months ago, not only this word, but also many words and phrases from his mouth, which were recorded by historians, and then gradually popularized and used, becoming the language vocabulary of this time and space.

The generals and officials of the Han State all knew that Deng Xing was not only a general, but also an expert in language and writing.

Fan Hao scratched his head, thought for a while, and suddenly realized.

"That's right! If you are close to the Great Scattered Pass at this time and want to climb up secretly, it is easy to be discovered. That... In the middle of the night, Zhang Han's soldiers may be lazy to sleep, and if they attack again, they will definitely win. Ha ha! I'm so smart! ”

Speaking of this, Fan Xuhan laughed.

Deng Yulong smiled and said in an encouraging tone: "You guessed right! That's what it does. ”

Han Xin, who was on the side, had thought of this for a long time, but he didn't speak, he would keep his promise and not show his talents too much in front of others. Now, he was sent to fight in the first battle of the Northern Expedition, and Han Xin was grateful to Deng Yulong in his heart.

Deng Yulong ordered the soldiers to rest well, eat some dry food when they were hungry, and nourish their spirits to act in the middle of the night, and he still needed to continue to observe the situation at Dasanguan.

At intervals, wooden shelves were placed on the city wall at intervals, and there was a basin on the wooden frame, and the fire burned in the basin, which was a common lighting method used in the army during this period, and the fuel in the brazier could burn for a long time.

In addition, soldiers armed with torches patrol the walls about every 30 minutes.

In the Dasan Pass, Yao Tong was drinking wine and eating meat.

In the armies of the various princes, there was generally a rule that alcohol was not allowed in the army.

However, this regulation has only become an ornament in the garrison of Dasanguan.

Since Xiang Yu was divided, there has been peace and quiet here, and no one would have thought that the Han army would come to sneak attack, not to mention, many soldiers are disgusted with acting as Zhang Han, a traitor of Qin, and when he stands guard every day, he is just making a show.

Especially in the cold, the soldiers on duty are even more talkative.

The guard general Yao Tong did not strictly manage it, anyway, it was impossible for the enemy to come, and he didn't bother to manage it so strictly.

In front of Dasanguan, most of the Han soldiers were sleeping, leaning against tree trunks, next to each other, or lying directly on the ground.

Although the weather was cold, Xiao He was well prepared before the expedition, and all the supplies were well stocked, including winter warm clothes.

However, there are a few people who can't sleep.

First of all, Deng Yulong, he has been in a state of tension in his heart, although he has a great chance of winning in the first battle, but theoretically there is no war with a 100% victory rate after all, crossing into this time and space, he doesn't want any accidents to happen, and he doesn't want to make Dasanguan the end of his life.

Deng Yulong understands some basic human psychology, and it is normal for the long-awaited things to be nervous at the beginning when it is actually implemented.

The second one who couldn't sleep was Fan Xu, he was a little anxious, he had been looking forward to the expedition for several months, and the Great Scattered Pass was just around the corner, but he had to wait for another half a night, which was like a year for him.

The third one who couldn't sleep was Han Xin, his mood was a little similar to Deng Yulong's, mainly nervous. He is not a simple general, he has the ability to become a good commander, and he will take many factors into account when it comes to warfare.

During the operation, will there be an enemy soldier who gets up to pee and finds the Han army sneaking up? Could it be that Nanzheng also had another lurking spy to report the Han army's movements in advance, so that the enemy army deliberately laid a trap in Dasanguan? Will it be ......

Han Xin thought about many possibilities in a row, these are theoretically possible, the opportunity for meritorious service is coming, and he doesn't want any accidents.

The fourth one who couldn't sleep was Wang Dahu, he was eager to charge into battle, kill the enemy and make meritorious contributions, and he was about to go to the battlefield, he was so excited that he couldn't sleep.

The north wind is still howling, the weather is freezing, and the first half of November in this period is equivalent to modern December, which is the cold season. Going out at this time, although the battle will be more difficult, but the enemy will be equally difficult, which will undoubtedly increase the chance of victory for the Han army with sufficient morale.

For example, in the night attack on Dasanguan, the morale of the Yongwang army itself was low, because the weather was cold, the defenders on duty in Dasanguan either hid in the city tower to be lazy, or leaned against the protruding position of the city wall to curl up and sleep, and almost no one still stuck to their posts.

After a "long" wait, it was finally early in the morning, and the Han officers and soldiers on the front line gathered.

"Soldiers, victory or defeat in this move, I wish you success."

After Deng Yulong finished instructing the generals, Han Xin led his subordinates to quietly approach Dasanguan, among which at the front were the soldiers who were equipped with ropes, and the metal hooks at one end of the rope were also wrapped with a layer of cloth, so as not to make a sound when the hooks were thrown on the city wall, the hooks and claws collided with the city wall.

Chen He led 2,000 sword soldiers to follow behind, and Fan Xu and Lu Juan led 2,000 halberd soldiers and spearmen each to follow behind the sword soldiers.

And Deng Yulong himself, with three hundred personal soldiers, followed behind.

At this time, a group of enemy soldiers armed with torches had just finished patrolling, and Deng Yulong was going to take advantage of the 30-minute gap to carry out a surprise attack.

Thousands of Han soldiers marched by the faint light of the moon. The general ordered them to launch a surprise attack within a quarter and a half hours.

At this time, the hundreds of soldiers on duty of the Yongwang Army in Dasanguan were all asleep, unaware that death was quietly coming.

Han Xin led the Tiance soldiers and soldiers to touch the city wall of Dasanguan, where they were standing between the two braziers, where the fire could not shine, to avoid being discovered by the enemy.

The soldiers in the front row began to move, they took the ropes, threw their hooks up the wall, and hooked them firmly onto the battlements.

Because the hooks and claws are wrapped in a layer of cloth, although there is still a sound when they touch the city wall, it is relatively slight and has not been detected by the enemy.

The Tiance army took Du Bo as a team, and the first team of soldiers quickly grabbed the rope and climbed up along the city wall, the movements were very skillful, and the speed was much faster than ordinary people, Wang Dahu was the Du Bo in this group of soldiers.

In the past, the Tiance Army conducted strict training in this area, and everyone had to have excellent climbing ability, and the reason why Deng Yulong formed the Tiance Army was first to consider for seizing, and now it finally came in handy.

Deng Yulong, who was in the rear, watched the actions of the soldiers in front, although he was inevitably a little nervous, but he was very confident in the soldiers he had trained and his military command ability.

The first 59 soldiers quickly climbed the city walls, and immediately the second Duber team followed.
