ps: Thanks to Leng Yingyue, denzi, Yunjuan Yunshu and eagle brother Zhou for their rewards. Taihangxing is the southernmost pass of the Eighth Routes of Taihang. It is more than 40 miles long. It winds between the mountains and crosses the Taihang Mountains. It starts from Hanoi in the south and connects Tianjingguan, the gate south of Zezhou in the north. It is the capital of the capital. Attacking the important channel of the upper party has always been a battleground for military strategists. Zhao Ba's occupation of Hanoi was equivalent to opening the south entrance of Taihangxing. The remaining problem was how to clear the entire Taihangxing passage. But Zhao Ba did not dare to go north again, because the road to Taihangxing was rugged, and there were many fortresses such as Yangchangban, Panshi City, Wanzi City, Dakou, Xiaokou, Guanyeling, Turtle Ridge, Tianjingguan, etc., and Zhaozhou's army was full of them. The cavalry's fighting style was incapable of capturing Taihangxing quickly. Therefore, while blocking Hanoi, he asked Zhong Shao for orders. At this time, Zhong Shao had just led the Cangzhou Army to the Heqing Camp, which was still a hundred miles away from Hanoi. The Weizhou Army, the Huaiyue Alliance Army and the Liaodong Security Army were lagging behind. Zhong Shao kept in mind Li Chengzhong's four-word principle of "soldiers are more valuable and faster", and instead of waiting for the entire army to arrive, he simply led the left wing of the Cangzhou Army in person, marched lightly, dropped all baggage, and started a rapid march towards Hanoi. The left wing of the Cangzhou Army is worthy of being the first-class main force in the Yan Army. It only took one day and one night to rush to Hanoi, setting a new record in the history of the Yan Army's war! After the left wing of the Cangzhou Army arrived in Hanoi, they only rested for one day before leaving Hanoi and entering the long and steep Taihang County. The two battalions of the front regiment of the left wing were at the vanguard. The left battalion was wearing the military uniforms of Liang Jun captured in Hanoi City. Under the banner of Liang Jun, they escorted carts full of food and entered first. The carts were pushed by brothers from the right camp. They disguised themselves as civilian husbands and hid their weapons in the carts. The commander of the former regiment was Zhao Wu. He was originally a general under Xiong Hu, the commander of the left wing of the Weizhou Army. He was also a soldier who came up step by step from the Yingzhou Army. Later, the General Administration of Military Staff implemented the strategy of rotating warfare in Shangdang and Bochang. Zhao Wu's battalion leader was transferred to Bochang to participate in the war. Because of his outstanding military exploits, he was spotted by Zhong Shao, who was then the camp manager of Bochang. He asked Liu Jinhou to take over the command of the left wing front battalion of the Cangzhou Army who died in the battle. After the Yan army expanded, Zhao Wu was promoted to the commander of the former regiment and the commander of the left camp of the former regiment. Li Yanzhi, the head of the army who followed him, also became the commander of the right camp of the former regiment, which was a smooth career. The Cangzhou Army is the main force of the Yan Army, the left wing is the main force of the Cangzhou Army, and the front regiment is the vanguard of the left wing. It is not an exaggeration to say that they are the main force among the main forces. Therefore, the reputations of Zhao Wu and Li Yanzhi have reached the ears of the King of Yan. They are already rising stars with a high reputation among the Yan army, and their future prospects are limitless. Zhao Wu led his troops to advance into Taihangxing. The first pass he had to face was Yangchang Ban. Fortunately, Yangchangzaka has been abandoned, because it is not far from Hanoi, and the coalition of princes did not station troops here, which made Zhao Wu's caution in vain. Passed the Yangchangzaka. The second pass is Panshi City. Panshi City is more than eight miles away from Hanoi, which is exactly a day's march in the mountains. The coalition forces of the princes set up a transit camp here. The guard stationed in Panshi City saw the long food transport convoy approaching and had no doubts in his heart. While ordering people to open the pass, he came down to inspect the vehicles, hoping to see if there were any good things that could make him a fortune. While he was looking through it. Leng Buding's left camp suddenly attacked and hacked him to death immediately. The right camp who was disguised as a civilian husband also drew his weapon from the cart. Screaming and pouring into Panshi City. There were not many defenders stationed in Panshi City, and it didn't take long for them to collapse. Dozens of defenders dropped their weapons and fled to the back. Zhao Wu left Li Yan to clear out the remaining enemies, while he led Zuoying in pursuit. In terms of foot power, none of the troops from the coalition of princes could catch up with the Cangzhou army. Zhao Wu chased for three miles and captured all the fugitives without leaving a single one behind. Finally, the news was not leaked. Zuoying stayed where he was, and after releasing sentinels, he camped on the spot while interrogating the captured escapees overnight. That night, Li Yan rushed to the right camp and caught up with Zhao Wu. According to a captured officer's account, there were not many garrisons in Wanzi City, Dakou, Xiaokou, Guanyeling, and Turtle Ridge. These places were in disrepair, and the coalition forces of the princes did not bother to reinforce and improve them. They just put a lot of A small number of troops were stationed to maintain the transport of baggage. For example, Wanzi City, Xiaokou, Turtle Ridge and other places only have a group of soldiers stationed there. Dakou and Laoye Ridge have more people, each with only one or two hundred people, half of whom are civilians. The real tough nut is Tianjing Pass at the northernmost point of Taihang County. The terrain there is difficult and there are heavy troops stationed there. As for how many soldiers there are, the officer does not know. Zhao Wu quickly asked the general to report his situation to Zhong Shao and asked Zhong Shao to send troops to respond. With the detailed military information of Taihangxing, the front regiment's attack became much smoother. They either rushed in brazenly with vehicles or smeared people overnight and sent people to sneak attacks. They hardly encountered any decent battles and easily won the battle. Every pass. Zhong Shao also urgedThe army followed the front regiment all the way to Turtle Ridge. But there are always surprises in everything. When we captured Turtle Ridge, a few deserters got into the ravine, and they lost track of them without paying attention. Zhao Wu was afraid that they would go back to Tianjingguan to report the news, so after a little rectification, he immediately urged the front group to go on their way. But when they arrived at Tianjing Pass, they were a little late. The pass was heavily guarded. As soon as the soldiers of the front regiment showed their heads, they were shot back by a hail of arrows. Obviously, the coalition of princes stationed at Tianjing Pass already knew their movements. Tianjingguan is the north entrance of Taihangxing and the southern barrier of Zezhou. It is only forty-five miles away from Zezhou. The key point is that these forty-five miles are all flat land, which is very easy to walk. If the Tianjingguan garrison brought horses - Zhao Wu estimated that they would certainly do so, then it would only take half a day for the garrison to report the news to Zezhou, including the troops sent by Zezhou. Source, I am afraid that the time left for the front group will not exceed two days. Zhao Wu was very anxious about this. Because right at the entrance of Tianjing Gorge, the mountains on both sides are as steep as walls, so Tianjing Pass can only be attacked from the front - and the front is a stone wall pass that is no more than ten feet wide and three feet high. How should we fight if we cannot deploy our troops, attack from the side, and cannot drag in siege equipment? The defenders closed the door and shot a bunch of arrows, and then carried their swords to the soldiers in the front regiment. They all yelled and laughed, which really made Zhao Wu angry. Several of them couldn't hold their heads back, and jumped to ask Zhao Wu for a fight. They wanted to lead the soldiers to charge hard, but they were all stopped by Zhao Wu. After waiting until evening, Zhao Wu finally brought Zhong Shao over. Zhong Shao was dusty and had a haggard look on his face. The clothes and armor of the officers at all levels surrounding him were covered with dust, which showed the hard work on the road. Zhao Wu stepped forward to say a few greetings, and immediately talked about the situation at Tianjing Pass. Finally, he asked: "Control, have you brought that thing?" Zhong Shao smiled and said, "Don't worry, we are right behind, and the brothers from the logistics camp are also there. When it¡¯s your turn, don¡¯t pee your crotch!¡± Zhao Wudaxi said: ¡°What do you want to do with your humble job?¡± Zhong Shao shook his head: ¡°Leave it to the logistics battalion. You will lead the team and get ready. Just rush in and fight when the time comes.¡± Because of the tight schedule, the logistics battalion did not care about eating and started working as soon as the patio closed. They emptied a few of the heavy carriages, made simple modifications, and then pushed them towards Tianjingguan. Although it was getting dark, countless torches were burning up and down, illuminating the battlefield exceptionally brightly. Seeing the Yan army pushing several strange "shield cars" up, the defenders braced themselves and waited for the Yan army to charge into the city. The modification of the logistics camp is actually very simple. It is to nail a three-inch thick and one-foot-high wooden board on the front of the Xi car, and tie a layer of coarse cloth that has been watered on the wooden board to become a simple shield car. Several shield cars lined up in a row and pushed forward side by side until they were thirty steps below the patio gate, forming an arrow-proof bunker. The first step of the work was completed. Dozens of brothers from the logistics battalion came to the back of the shield truck, wielding hoes and shovels, and worked hard to dig. What they have to do is the second step, starting from here and digging a tunnel down to the patio. The distance of thirty steps is not far, but it can guarantee that you will not be hit by the rolling logs and rocks. The only thing to worry about is the defenders throwing fire oil cans, so a few people were specially arranged to take precautions. They held wet linen blanket, ready to put out a fire. Zhao Wu asked Li Yanzhi to bring sword and shield men from two cities and line up outside the range of Guancheng's bows and arrows. If the defenders attacked, they would be responsible for thousands of fights to protect the brothers in the logistics camp. At the same time, Zhao Wu also brought up all the bows and arrows, and shot at each other across the distance and Guan Guan. The banging sound of digging continued throughout the night, and the logistics battalion rotated several times to maintain the progress of the excavation. To be honest, this section of the road is not easy to dig because there are too many rocks, which really affects the work of the logistics camp. It wasn't until daybreak the next day that the tunnel was nearly completed. The defenders were still trying to harass and stop the Yan army in the first half of the night, but they lost interest in it from the second half of the night. The tactic of digging tunnels to attack the city is already very old-fashioned, and there are countless ways to deal with it. You If you want to dig, dig it, and when the time comes, you will never come back! After the tunnel was dug, several young officers came to the logistics camp. Although they were not old, the ranks on their armbands were not low. Several young officers carried a bunch of packages and walked down the tunnel. After a while, one of them showed his head, asked for a few pickaxes, and then sank down again. Zhao Wu stayed up all day and night, always staring at the entrance of the cave. Not only him, but also senior officers from Zhong Shao and below, the Cangzhou Army Headquarters and the left wing were all awake, and they were all waiting nearby. I don¡¯t know how long it took, it seemed like a few long hours, or maybe it was just a cup of tea. Several young officers retreated from the tunnel, and then worked together to bury the entrance of the cave. They were extremely careful when burying it, as if something happened.??Broken some treasure. One of them lit a fire, and a wisp of green smoke followed the sound of chi chi. Several officers turned around and ran away. At the same time, the order to "cover your ears" came, and Zhao Wu quickly covered his ears with both hands. The whole mountain seemed to have collapsed as the earth spun around! (To be continued)
