Ma Chao did not fully adopt the defensive strategy suggested by Zhao Yun - firstly, it did not conform to his personal military style, and secondly, the Duoxiliang Qiang Cavalry under his command relied on persistence and could not exert their inherent power. ¡÷So Ma Mengqi thought over and over again and after discussing with the generals, he assigned responsibilities and guarded each city. However, he personally led 8,000 troops and horses to rush west to aid Shiquan. At the same time, Ma Chao also wrote to Gan Ning, who was guarding Bazhong, requesting to send troops north to aid Hanzhong. You don't intend to get involved in the dispute between Liu and Liu, but you can't help but guard Hanzhong, right? However, Ma Chao hurried and hurried slowly, but he was still a step late. He arrived at Akasaka and immediately reported that Shiquan had been lost. He discussed with Ma Dai: "If I set up camp in Akasaka, sandwiched between the corners of the city wall, even if there are tens of thousands of Wei people, we can still be enemies. However, I am afraid that they will follow the southern route and capture the city. What can I do?" From Shiquan County Pointing to the Hanzhong Basin, there are two possible roads, the north and the south. The first one is from north to west, following the Mian River to the front of Akasaka. Akasaka is located at the eastern end of the Hanzhong Basin. The village is surrounded by mountains to the south, and there are more than ten miles of gentle slopes to the north, which is convenient for cavalry to gallop. Ma Chao immediately wanted to go south and set up camp on the mountain. If the entire Wei army came to attack, the defenders of Akasaka could disrupt his retreat. If the Wei army attacked Akasaka, or divided his army into two, the Ma family's cavalry could charge and trample them on the gentle slope. . Ma Mengqi is still very confident in his cavalry and the ability of his generals. He also predicts that the Wei army will attack in a hurry and take a dangerous route along the Mianshui River or in the Ziwu Valley, so the number of cavalry will not be too many. , even if the enemy is outnumbered, he still has a considerable chance of winning. However, if you send troops from Shiquan, you can also go west and then north, directly to the southeast of Chenggu west of Akasaka - although the road is more steep, it is shorter. Maybe the Wei people wouldn't take this shortcut. Once the Wei army surrounded the city. You can take Nanzheng directly from the west. Ma Chao must rush back support from Akasaka, which will change the situation between home and away, which is very disadvantageous. According to Zhao Yun¡¯s suggestion that day, the reason why he planned to temporarily abandon Shiquan and defend the western front as far as Akasaka was because this area has entered the Hanzhong Basin, making it easier for the Ma cavalry who had just arrived to help. If Ma Chao can reach Shiquan first, the road will be narrow and dangerous. The cavalry is difficult to use, but if the Wei army can be blocked to the west of Shiquan and the cavalry dismount to defend the city, then the cavalry can dismount and defend the city. Even if the casualties are heavy and the Wei army is prevented from entering the battle, it can still be considered a victory. But now that there is no rush to save Shi Quan, he must consider giving full play to the mobility and impact of the cavalry - should he help block the mouth, or should he simply let the enemy in and fight? What would be more beneficial? Ma Dai said, if you want to put the Wei army into the basin to fight, you must abandon the defense of Akasaka - you must still be blocked in Akasaka. What if someone takes the south road? Then we can only focus our defense on Chenggu. However: "The Wei people are in the mountains, and it is easy to make enemies. If they are in peace, they can only rely on the three thousand cavalry of the headquarters. The number is too great" The strength of the Shu army is mountain warfare, not plain warfare. Once the Wei army is in peace, , plowing away the three thousand cavalry, the remaining infantry, especially the former Hanzhong Army whose elite troops have been depleted, may not be their opponents - "My brother thinks that it is better to defend Akasaka." As for the southern route, we had to send A troop went to gag it. Ma Chao agreed, so he set up camp in the north of Akasaka City, sent an envoy to Nanzheng, and ordered Han Lieutenant General Du Lu to lead 2,000 infantry to reinforce the city and cut off the road to the south to build a stronghold. In fact, at the same time, after capturing Shiquan, the Wei army also started a big debate over whether to follow the north road or the south road. Cao Zhen suggested taking the southern route: "I am in a hurry to enter the Han Dynasty. I don't know when the backup will arrive, so I have to use my dangerous ears. I heard that the enemy has aided Akasaka. If I can highlight the Nanshan Mountain and surround the city, I can block it in the east of the city." The other armies marched twice as many times as they could to reach Nanzheng in one day and one night. Even if they could not defeat them suddenly, they would also be able to shake off the traitors. "The key problem is that Fazheng's deployment in Hanzhong had already reached Chang'an through spies. At that time, Cao Zhen saw it. I can't help but have a headache, thinking that these numerous cities and towns are all dependent on each other. How many lives must be taken to open a passage? So as soon as he got the news that there was civil strife in Shu, Liu Feng and Huang Quan mobilized a considerable number of Hanzhong troops to go south, and Zhang Fei was soon assassinated by his subordinates, he felt that it was a God-given opportunity. On the one hand, he hurriedly reported it to Luoyang, and on the other hand, he made preparations. Soldiers and horses were prepared in advance for the southern invasion. As soon as Cao Cao's order to send troops arrived, Cao Zidan eagerly marched his troops and set off - almost completely different from his prudent posture in Goguryeo that day. Of course, this is because Cao Zhen did not have much motivation when he invaded Goguryeo that day. He felt that victory was useless and defeat would be shameful. Besides, Cao Zhen ordered him to move forward cautiously, so he should go slowly and leisurely. Now is a rare opportunity to destroy Shu. I am afraid that if I am too late, if the situation changes again, not only will it be difficult to take down Hanzhong, but the 20,000 men under my command may even be in danger of being destroyed - when it is time to take risks, we must take risks. Because according to the intelligence of the spies, the Hanzhong infantry defense mainly faced the north, from the entrance of the valley to Nanzheng and its left and right Yangping, Mianyang, Huangsha, Chenggu, Akasaka, and Shiquan lines. Fortresses were set up layer by layer and defended like iron barrels. generally. But for the southern side of the Hanzhong Basin, defense has been relatively neglected - on the one handIt is difficult for the army to move to the southern front, and the Shu Han Dynasty cannot provide more soldiers and horses to set up a stronghold in all directions. Therefore, the mountain pass on the south side of the city was not fortified originally, so Cao Zhen wanted to take the risk and go from the south road, protruding from the mountain road in one fell swoop, and take the city directly. However, Jingzhou general Niu Jin opposed Cao Zhen's strategy and advocated taking the northern route. His reason is also very good: the spies did not detect it, so it does not mean that there is really no stronghold defense south of the city. Originally, that place did not need to be defended, but since we captured Fangling County and directly threatened Shiquan, the Shu people should consider that once Shiquan is lost, there will be a big vulnerability south of the city. Well, take a step back and say, there was no stronghold there originally, so how do you know that the Shu people will not send an army to block it now? Cao Zhen said that it is precisely because of this possibility that we must move forward quickly from the south road. Now that Hanzhong has insufficient troops, it may not be possible to send many people to guard the south of the city. Even if they are sent, they will not be able to build a stronghold in a hurry. If the military plane is delayed and they really erect the stronghold, we will no longer have any opportunity to take advantage of it. Niu Jin shook his head and said that if there is no time to take advantage of it, then don¡¯t take advantage of it. The biggest danger of taking the southern route is that it is not easy to transport food and grass. Once someone blocks the mountain pass, I am afraid that I will have no place to go and no place to retreat, and I will definitely suffer a big defeat. It's much easier to take the North Road. You can pass Mianshui to continuously transport grain and grass from Jingzhou. Junhou Cao, you don't take the right path, but you take risks. It's really hard for me to understand. Cao Zhen said that it was precisely because of the lack of food and grass that he took the risk. Even if he took the northern route, the main force of the Jingzhou army would probably have to go up the river to fight Bajun, and they would not be able to give us much food. Once the troops were stationed in the east of Akasaka City, they would not be able to advance even an inch. , I am afraid that in the end I will have to go back home. The two generals each held their own opinions, and neither could convince the other. The key is that Cao Zhen was ordered to command all the people in Guanzhong after Cao Cao left Chang'an, but Niu Jin was a general in Jingzhou, and Cao Zhen had no control over him. As for Sima Yi, the chief general in Jingzhou, he may not have arrived in Nanjun yet - even if he had arrived, Cao Zhen would not have much time to write a letter to discuss with him. As for Shixun, the commander-in-chief of the army and the chief governor, he has just received his report and has already entered Chang'an - if he goes to fight in front of Shixun and it still doesn't help, then he might as well just listen to Niu Jin's words. Cao Zhen looked around, but Xu Huang and Shen Yi were silent - if Lu Ziming were here, he might be able to help me. It's a pity that after Lu Meng originally planned to join forces, he was summoned away by Shi Xun only half way away - Shi Xun thought that I am a two-handed swordsman in fighting, and I must have a competent staff officer beside me. Although I sent someone I went to summon Jushou, but unfortunately I couldn't get there. Since Lu Meng had just entered Ziwu Valley after his marriage, it was better to summon him to his side. While they were arguing, they suddenly heard someone say: "The north road is solid, but the south road is also necessary." Niu Jin glanced at it and saw that this person was not him. He was the one who had made great contributions in the capture of Fangling County in the past. His fate refers to Ma Su, Ma Youchang, a doctor in the Nanjun Army Corps. Niu Jin couldn't help but frown and thought to himself, where are you from? How can you speak for the people in Guanzhong? Ma Di first apologized to Niu Jin, and then pointed to the map: "If our army wants to march towards Nanzheng, Nanxiang must be taken. How could we know that Bazhong will not send troops to help?" From Shiquan to the west, there is another Nanxiang. The county is very small. It is estimated that the population is only more than 500 households. Even if the surrounding people are included, the population cannot reach 5,000. The key is that there is a small road in Nanxiang that goes over many mountains and reaches Xuanhan County in Brazil County in the south. If Gan Ning sends an army from here, no matter whether we take the southern route or the northern route, we will easily be taken back by the enemy. The reason why Cao Zhen and Niu Jin did not consider this danger was because the road was too difficult to walk and the distance was long. If they were in danger from Hanzhong, they sent envoys to Bazhong for help. If Bazhong sent troops again, even the fastest Thirteen or four days. Cao Zhenzhen said that if I can't besiege the city in half a month, I'd better just pack up and go home. Niu Jin also thought, if I can't break through the Akasaka defense line in half a month, there will probably be problems with the food transportation, so it's better to retreat to Shiquan. But Ma Su said, no one can guarantee that Gan Ning had not received Zhang Fei's order long ago, asking him to send troops to help defend Hanzhong. Maybe Gan Xingba is already on the way this time, so what should we do? Therefore, our army must send a force of troops to seize Nanxiang City first - "I ask you to lead the army to defend the flanks of the two generals." If Xun was here, he would definitely nod: "What You Chang said is true "Yes." Then he immediately shook his head: "You can't go without being in battle." It's a joke. It may be a bit too much to say that you, Ma Su, are "talking on paper", but you always make mistakes when planning strategies. That is clearly recorded in history - Zhuge Liang dares to use you, but I dare not use you! However, Cao Zidan and Niu Jin did not know each other that way. Niu Jin had seen this young man's strategic vision and personal courage, so he immediately agreed. Cao Zhen took a look - of course you are familiar with your person, and if you said yes, let him be the one. So he immediately sent Ma Su and an army of four thousand to capture Nanxiang. After another long discussion, Cao Zhenzhen decided toUnable to convince Niu Jin, he finally had to agree to go through the North Road. So he bumped into Ma Chao face to face. (To be continued.)
