Pujin Pass, in the Warring States Period, Wei Zhi about this, to guard against the Qin State of Hexi, was also called Pu Hanjin. During the Qin State, Qin Shi Huang made a gallop road, from Xianyang north out of Liyang Road, that is, Pujin Pass Road, this road can go straight from Xianyang to Jinyang.

When he arrived in the Han Dynasty, he began to set up customs officials in Pujin to ridicule the brigade. Cao Cao of the Three Kingdoms attacked Ma Chao and Han Sui in the west, and ordered the generals Xu Huang and Zhu Ling to cross Puhanjin and base their camps in Hexi. Xu Huang wrote a letter to Cao Cao, saying that at present, our army is stationed in Tongguan, and Ma Chao will no longer defend Pujin, knowing that he has no plan.

When the emperor opened, the capital of the Sui Dynasty was Guanzhong, and attached great importance to the traffic defense of Pujin Pass, erected a pontoon bridge on the Yellow River, and built a city in the river, named Zhongyun City. In ancient texts, the meaning of sand in the water is 潬. Therefore, the name of Zhongyun City is the meaning of building the city on the sand in the river.

By the time Li Chongjiu's car arrived in front of Pujin Pass from Wenxi, the land and water attack on Pujin Pass had been launched for two days.

The war drums under the city were beating, and surrounded by the generals' staff, Li Chongjiu climbed the high platform and looked into the distance.

But I saw the turbid yellow Yellow River rushing through from afar, and on the surface of the Yellow River, there were hundreds of jet-black warships. These warships are storming down the river, and the city of Zhongyun in the river.

The generals who presided over the attack were Li Yuanji, Li Yuanji, but seeing that Li Yuanji personally held a halberd, stood on the bow of the ship, and shouted and commanded the soldiers on the left and right. The front row of boats approached the city, and the crossbowmen of the Zhao army standing on the bow of the ship continued to shoot rockets into Zhongyun City. There were already several places in Zhongyun City, and black smoke was billowing out.

On the water, Li Yuanji ordered the Zhao army fleet to approach the city by boat, and threw it into the city with firewood and oil to burn the city. The Tang army in the city also desperately went out of the city to resist. Intercept the Zhao army's fireboat and shoot the Zhao army into the city. Throw it out of the city.

The fierce battles on the city were fierce, and on land they were average.

After two unsuccessful attacks on Zhao. Li Tang strengthened his defense against Pujin Pass, and last year he conquered 50,000 people and rebuilt Pujin Pass. And in addition to the four gates, six dock forts were added to each, and a layer of loess rammed earth walls were built outside the dock forts, which became a city within a city.

For the fortified city built by Li Tang with great effort, even if it is with the courage of Luo Shixin, the strategy of Su Dingfang, and the heroism of Wei Chigong. The three famous generals of the Zhao army stormed for two days, but still did not shake the defense of Pujin Pass.

At the beginning, Li Chongjiu gave the order to the three of them to cross the Yellow River within three days, but today is the third day, and the three of them, plus Li Yuanji and Li Yuanji, followed the flow of a total of 45,000 troops, and they were also in a hurry, and launched the most fierce offensive towards Pujin Pass at that moment.

Look up from the high platform. But seeing that at the east gate where the fierce battle was the farthest away, the attack lineup of tens of thousands of Zhao troops was like an undulating ocean, and the soldiers in the front row were holding huge shields. The second platoon of soldiers held strong crossbows, and the soldiers behind them raised the siege ladder and reached the city.

The outermost layer of rammed walls. Half of it had already been demolished by the Zhao army, and the soldiers rushed through the middle. And the place of the east gate. Of the six dock forts built by the Tang army, three were also captured by the Zhao army. On the remaining three, the soldiers of Zhao are also attached to the siege of the city.

The general Wei Chi Gong sat near the rammed wall and commanded the siege.

As for the rest of the Zhao army, under the leadership of Luo Shixin and Su Dingfang, they launched an attack on the Tang army at the east gate. On the city wall of Pujin Pass, the Chengzi banner fluttered high, and there were constantly rolling logs and stones falling from the city, and the Zhao army besieging the city braved the arrows and attacked the city.

The Zhao army attacked very fiercely, but the Tang army also fought very bravely under the disadvantage of troops.

Li Chongjiu looked at it for a while, and said to the left and right: "You see that the six dock forts built by the Tang army in front of the east gate have very effectively divided the offensive forces of our army. Let our soldiers and horses attacking the city wall not be able to concentrate together, the formation is damaged, and it is futile to fight like this, who is the general of the Tang army defending the city? ”

"Cheng Zhijie, also known as Cheng Biting Gold."

Li Chongjiu suddenly said: "It turned out to be this person." ”

At this time, the fast horse galloped towards the high platform, and a cavalryman jumped off his horse and announced to Li Chongjiu: "Your Majesty, on the west bank of the Yellow River, I found the army of Li Tang, and there is also the banner of Emperor Li Tang. ”

Hearing this, the generals of the Zhao army couldn't help but be shocked, and Li Shimin actually came to Pujin Pass in person, which was to plan a decisive battle with Li Chongjiu by the Yellow River.

Li Chongjiu looked into the distance from the high platform, but when he saw that it was really on the west bank of the Yellow River, countless military flags suddenly appeared, and there was a scene of smoke and dust billowing all over the eyes, and the momentum seemed to be very big, but the distance was too far away, and it was impossible to see how many soldiers and horses there were.

Li Chongjiu said in his heart: "If Li Shimin really came here to garrison Pujin Pass, then why did he give up Jiangzhou so lightly before." Without Jiangzhou, wouldn't it be very passive to guard Pujin Pass. ”

Li Chongjiu said to Ji Chuan: "The west bank is too far away, our army can't reconnoitre, and I don't know the specific strength of the enemy, but I think that this is Li Shimin's suspicious strategy, and his main force will not be here." ”

Zhang Xuansu on the side said: "Your Majesty, Weichen also thinks that if Li Shimin really intercepts us at Pujin Pass, what is the difference between this and guarding Chang'an." As long as our army confronts him in the east and west of the Yellow River, then when Wang Junkuo's Western Route Army arrives, Li Shimin will undoubtedly fall into the predicament of being attacked by the enemy on his back, and he will not make such a faint move. ”

Yu Shinan said: "But we can't guess that there is no, if Li Shimin really leads the main force on the west bank, then our army rashly crosses the river and attacks, and there is a danger of being attacked by the Tang army." ”

Speaking of this, Yu Shinan paused and said to Li Chongjiu: "The Tang army has been garrisoned at Pujin Pass as early as possible to prevent our army from crossing the Yellow River westward, if it drags on, it will be unfavorable for the army. ”

After listening to Yu Shinan's words, Li Chongjiu pondered after listening to it.

Yu Shinan's Jianyì is to cross the Yellow River from Longmen Pass upstream of Pujin Pass. Longmen Pass is the place where the carp jumps over the Longmen, and it is not impossible to enter the army from here, but the route has been stretched for more than 200 miles, and the grain road and supply line are also more than 200 miles away.

As soon as Yu Shinan's voice fell, Zhang Xuansu immediately objected: "Your Majesty, Pujin Pass is the key point of Guanxi and the convergence of Hedong. ”

Ji Chuan said: "Pujin Pass is difficult to attack, not for a while, at present, the main force of our army is gathered under the city, and the 200,000 troops break through this small city without much effort." As for Li Shimin on the other side, Weichen thinks that even if he really arrives, there is no need to worry. ”

Li Chongjiu listened to Zhang Xuansu and Ji Chuan's opinions, and also agreed: "I agree with Zhang, Ji Erqing's meaning. However, Yu Aiqing's opinion inspired me, and ordered Li Yuanji to carry Xue Wanjun's 5,000 men and horses to land at Longmen, pretending to divide our army. In fact, our army is still attacking Pujin Pass! (To be continued......)
