? "The name of Sanguan originated from the Sanguo. In the Yin Dynasty, Sanren lived here, so the name of Sanguan was Sanguan, cough cough..."

The Yingdu was not cool in summer. The generals and doctors who attended the military convention filled the court. Even if there was ice and drinks to keep the heat, the court still seemed hot. The continuous wars and could not withstand the huge pressure of any failure. Si Yin Li was also old, and his voice seemed tired. Although he coughed several times and tried hard to raise his tone, it was still not loud enough.

"There are many ways to cross the Qinling Mountains, but only one can be used to sail, so our army will pull out Sanguan." The four passes in Guanzhong, Sanguan is one of them. The Grand Sima Mansion originally had a terrain sand table, but there were too many people in the court, and the sand table could not be erected, so Li Jie could only let someone hang out a map of one-five hundred thousand and explain it to the map.

"To the north of Sanguan, the Hanshui River comes from the northern foot of the Qinling Mountains, and enters the Wei River through the Zhougu Road. This water is about a hundred miles long, and the boats and oars are about twenty miles wide. To the south of Sanguan, the Mianshui River comes from the southern foot of the Qinling Mountains and twenty miles south of Sanguan. The Mianshui River can already be used. Hanshui, Mianshui, are only forty miles apart along the official road. The northern mountain of Lingnanling is slower than the other crossings. If this pass is pulled out by our army, it can be dug a water canal forty miles. The two oars and the middle wing warships are dragged by a steam engine and then enter the Wei River..."

All mountain roads crossing the Qinling Mountains were all along river valleys, such as the Baoshui and the slanting waters of the Baoshui Road. Due to the Wudu earthquake in the early Han Dynasty, the Great Lakes of Tianchi, the Mian River, where the water level was lowered, was unable to sail upstream. In the middle of the Western Han Dynasty, he planned to connect the Baoshui River to the slanting waters to replace the Chencang Waterway, but unfortunately, with the technology at that time, the Baoshui Road could not be changed into a waterway, so he had to give up.

After the earthquake, the upper reaches of the Mian River, which originally belonged to the upper reaches of the Han River, was captured by the Jialing River, and the upper reaches of the Han River became the upper reaches of the Jialing River. At the same time, the Chencang Waterway, which could have been 20 miles south of Sanguan, could only reach Yuguan.

Yuguan is not twenty miles away from Sanguan, and Yuguan is more than one hundred kilometers away from Sanguan. The first battle between the Southern Song and the Jin Dynasty was in the Monk Yuan on the east side of Sanguan. After that, the war in this direction occurred at Xianren Pass. Xianren Pass is near Yuguan. The reason why the Song people gave up Sanguan was precisely because the northernmost part of the Jialing River water transportation could only reach Xianren Pass. The food and fodder transport at Sanguan was not good, and the soldiers were hungry.

The earthquake that caused the disappearance of the Tianchi Daze in this era did not occur. The high water level of Mianhua can pass through the Sanguan Pass. The cargo crossed the Qinling Mountains, which was not steep, and after forty miles, it could be loaded from the Hanshui River to the Wei River. The plan of the Grand Sima Mansion was to pour one or two canals about 40 miles long with concrete, and then drag two oars, middle wing warships, baggage and transportation boats, across the Qinling Mountains, and into the Wei River.

The last time he attacked Guanzhong, the Qin people were firmly in the walls and clear fields, and there was no food and fodder within a hundred miles. This time, the food and fodder were prepared by the Chu army, and there were only forty miles from Yingdu to Xianyang. This advantage was incomparable to Baoxi Road, Ziwu Road, Wuguan Road and other mountain roads across the ridge, and it was also the reason why the Chu army must have pulled out Sanguan.

Only by unplugging Sanguan can the Chu army truly enter Guanzhong and turn Guanzhong upside down. In order to achieve this goal, in the east line, the Weishui defense line not only barely gathered up the 100,000 Qi troops who were not sure they could not fight, but also arranged four Lu Dimensional divisions, three Song Dimensional divisions, two Wu Dimensional divisions and one Huaiyin division to support it;

In the direction of the northern line, there are more than 30,000 Wei troops in the south city of Daliang and 20,000 Zhao troops in the north city. Fangcheng has three divisions of Xiang and five new divisions of Zhu clan garrison. In critical moments, Li Xin can lead his army to attack Fangcheng, and eight divisions only guard the four important nodes of Wancheng, Fan Xiang, Linpin, and Shangmi.

There are three routes on the western line, one is Wuguan Road, the other is Shangji Road, and finally Chencang Road.

Wuguandao originally had three divisions of the E Division and Tang Division stationed. The combat department meant that it could not attack from Chen Cangdao alone. While taking the defensive line on the eastern and northern fronts, at least three divisions of the western front would have to attack at the same time. One of them was Wuguandao. General Xiong Jing led four divisions of the Ying Division, twelve newly formed brigades that had just been reduced, and all troops that seemed to be able to fight were pretending to attack from Wuguandao.

The Chu army attacked Guanzhong from Wuguan Road the year before, and the Qin people still remembered this freshly. In order to prevent the Chu army from coming again, many valleys north of the Qinling Mountains built dams and walls, but no matter how thick the dam wall was, it could not withstand the explosion of gunpowder. This time, the reason why I did not choose to attack Guanzhong from Wuguan Road was not that I could not attack, but that the road was not open to ships and could not ravage the entire Guanzhong even if I attacked Guanzhong.

The Chu army attacked from Wuguan Road, crossed the Qinling Mountains, blew up the walls and dams, creating a situation where a large-scale attack would be launched, and Guanzhong would inevitably be shocked. Whether the Qin State gathered troops or fled in a snail, Xianyang would be distracted. This would be the best effect, if Xiong Jing personally led the Ying army to appear on the southern foot of the Qinling Mountains.

Wuguan Road attacked Guanzhong as a void. From Chengxian to the north of Juyi, it could go north to Shangqian County on the south bank of the Wei River. This was another attack route. Shangqian County was established as Qinzhou in the fifth year of Qin Shihuang, which was the Tianshui of later generations. Crossing the Wei River from Shangqian could go to Longguan Road. If the Chu army had troops from Shangqian County, the entire Longxi would be panicked.

Among the twenty-one counties under Longxi County, there are Didao, Didao, Wuduo, Rongdao, Distinguishing, Idedao, and Guidao. Therefore, eight roads are passed one third. "There are barbarians in the county called Tao." For hundreds of years, the barbarians did not assimilate into Qin people. They were unwilling to be ruled by Qin. Once the Chu army and the Qiang people appeared in Shangji, when Longxi was in chaos, they could also deviate from the flanks of Sanguan along the Wei River.

The upper qi road is left and the Wuguan road is right. The left and right restrain Guanzhong, creating opportunities for the real main attack direction Chen Cangdao. This is the final combat plan determined by the Operations Department. The ten divisions on the eastern front and eight divisions on the northern front were subtracted. After the reduction, there were only 37 and a half divisions left. The Chu army of the twelve brigades had only 19 and a half divisions and twelve new brigades for attack.

Then subtract the eight divisions and twelve new brigades in the Wuguan Dao direction, and then subtract the Sui and Chengyang divisions in the upper Dao direction, leaving only Chen Shi, Yang Xia Shi, Xin Cai Shi, Xia Cai Shi, Qisi Shi, Xixian Shi, Yiyang Xiyang Yi Shi, Huainan Zhushu two divisions, Cangwu County Brigade, and the Ninth Division one Brigade, with a total of 60,000 people.

Fortunately, there are still 50,000 Zhao troops, 30,000 Ba people, and 20,000 Yue troops in this direction. In addition, the Sui and Chengyang troops who completed the detour from Shangji in the later period, more than 20,000 Qiang and Rong people will reach or even exceed 200,000.

This level of attack will inevitably allow Chu to take the strategic initiative. If Wang Jian's army and Li Xin army do not return to Guanzhong, the soldiers who escaped from the battle of Weinan under Meng Tian and Zhao Yong will not be able to withstand the attack of these 200,000 troops.

According to the news from the Ministry of Knowledge and App, the Qin State had a huge famine last year. Because the war continued, this year, the entire Qin State had food except Xianyang, and the government and the army had food. The famine was even worse. The whole country was looking forward to this year's autumn harvest. The 200,000 army invaded Guanzhong in the September and October harvest season, robbed and burned millet fields, grain and fodder, and the result would be disastrous.

Just like the Qin cavalry broke into Qi territory this spring and the Wei territory raided farmers sowing seeds, war has inevitably evolved from simple battle formations to large-scale destruction and killing against enemy cities, transportation, agricultural production, daily necessities, and populations. The result of this destruction and killing will cause the enemy's war potential to drop sharply, and eventually lead to defeat.

After lunch, Li Qi finally introduced the entire combat plan. The generals were the discussion between the doctors. This kind of discussion was the connection between the front and rear, including materials, transportation, manpower, and animal power;

The second is the response of each defense line and how to deal with various accidents. The eastern line, which Dongye Gu was responsible for, must cooperate closely with the Qi people to defend Weishui and Muling Pass; the Zhao and Wei armies defending Daliang must defend Daliang, a key waterway pass, even if the Qin army invaded Dasong County and Shangcai County; Xiang Chao, who was stationed in Fangcheng, should not fight with Li Xin, but should continue to delay Li Xin and delay his actions in Fangcheng;

Finally, the cooperation between the three armies on the western front was between the three armies. Chen Cangdao and Shangjidao would merge into one army in the later stage of the battle. The Ying army and other brigades in the direction of Wuguandao would only retreat from the Danshui to the Han River and follow the water out of the Sanguan Pass and enter the Wei River.

Such a huge military proposal could not be completed in one afternoon. The day before Xiong Jing was about to set off for the alliance between Nanzheng and Dahao Shi, the discussion of the first two parts was barely over. The key part of the last part, the military proposal of how to attack and defeat Sanguan had just begun. This time, there were very few people in the court, only Xiong Jing, Naoji, Li Qi, don't let me, E Le, fight against Zhi, Chengtong, Zuo Kai, Ba Hu, Deng Sui, Zhuang Wudi, E Zhuo and more than a dozen people.

"The danger of Sanguan is not in the Qinling Mountains, but in the old way." Li Qi first talked about the offensive against Chen Cangdao. This time he used not a map, but a sand table. His finger was directed to a place on the sand table. This place of Mian River flowed out of the mountain stream, with high peaks on both sides, and the river channel was filled with sunken boats blocked by Qin people.

"The southern slope of the Qinling Mountains is gentle and the northern slope is steep. Our army from south to north to Sanguan Pass, and the Qin people have no defense. Now the fortified areas are all here south of the old road." The Mianshui River is deserted, and this rugged land has no official name. "The two sides of the waterway are rugged and unfeasible, and it is not allowed to climb by land. There are many sunken boats in the waterway, so I float one, and the Qin people in the upstream place another one..."

"You can't use the huge silk to cross the river to block it?" Xiong Jing looked at the south of the old Tao and interrupted it.

"Report to the king, it is not possible. The Qin people are not only sank boats, but also sank wood. The huge silk crossing across the river can block the sunken boats and not sank wood." "The two mountains are intersecting here, and our army cannot go up, and the Qin soldiers stand on the mountain. The sunken boats outside the stream can float up. The Qin people in the stream hit me with a crossbow and stone bullets. Our army cannot clear the sunken boats in the stream." E Zhuo said. He went to see it specifically. This is not a problem of removing silt, but a problem of combat between high ground and low ground.

"Can't fire the fire?" Xiong Jing was not giving up.

"No." Li Qi shook his head, "The Qin people covered it with big seals and stone walls, and placed cannons in the boat, but they were all not hit."

"What if that?" Xiong Jing looked at the mountain stream that had been more than ten miles away.

"If you attack along the coast, even if you capture this section, there will be still..." Li Qi was talking about the section that stopped the Chu army from advancing. This section was only a dozen miles away. When his fingers moved back, Xiong Jing saw a longer section of mountain stream, which was at least fifty miles long. He gave up helplessly and listened to Li Qi's following.

Li Qi returned to the Nanzheng Basin. He pointed to the Baoxie Road in the north of Nanzheng and said, "This Baoxie Road is a hundred miles north of this, and the mountain is divided into two, one is the Baoxie Road to the north, and the other is the northwest. Walking along this road a hundred and twenty miles west, you will be under a large mountain. The height of this mountain is beyond the Qinling Mountains. The natives call it Yuanwu Mountain, saying that the top of the mountain is only five feet away from the sky."

"Yuwu Mountain?" Xiong Jing just remembered the name and was not surprised at its height. "Gare of altitude?" The barometer can measure air pressure and also measure altitude. He asked.

"More than two thousand meters." Li Qidao. The road he mentioned was that Chencang Road could not be transported by water. He went west from Wuguanyi Town on Baoxie Road, passed Liuhou Town, Chaiguanling, Liufengguan line to the bottom of Fengling, and crossed Fengling to Fengzhou. It is said that Liu Bang went out of Hanzhong and sent elite troops to enter Chencang Road and occupied the old Taoist city, which opened up the entire Chencang Road.

The mountains between Guanzhong and Hanzhong are steep and the road is the most complicated. Xiong Jing is not sure which road is on this road. He only asked: "If you pass Yuanwu Mountain, you can enter Sanguan?"

"Okay." Li Qie replied. "But the Qin people were not unprepared. Meng Tian stationed troops in the old Daoyi City, and sent soldiers to guard the waterway while ordering people to guard Yuanwu Mountain to death."

"In this way, we can only attack hard?" The biggest problem for the Chu army to snatch Chen Cangdao was that the Qin people had already equipped them.

"However, if you can use elite soldiers to attack him at night, the Qin army may be defeated. Our army will seize Yuanwu Mountain and face high. The artillery can attack the enemy at the foot of the mountain." Li Qi said. "Or the road leads to the foot of Yuanwu Mountain and attack him from afar."

"There are only these two strategies?" The combat plan for how to capture Chen Cang Road was also released. The key pass of Chen Cang Road is not Sanguan, but in the south of the old road and Yuanwu Mountain. The most secure way is to penetrate from Yuanwu Mountain to the back of those mountain streams.

"There are only these two strategies." Naojiu remained silent until Xiong Jing asked.

"Sanguan is 150 miles away from Yuanwu Mountain, and no one can enter along the road. Recently, I heard that the Qin people summoned the soldiers who had cut off their left toe in the past..." Don't let me report the situation in time.

It’s no surprise that idle people cannot enter the strategic location, but the Qin people recruited those useless people with only one leg...

"Why are the deposed soldiers recruited?" Xiong Jing looked at me in confusion. "Can they fight?"

"I don't know." Don't tell me. "I only know that all the deposed soldiers are summoned to the counties and towns of Guanzhong, but for some reason."

"Although the Qin people defeated Qi, there were many soldiers who died and injured, and fewer soldiers could fight, so they had to use them." Dou Yuzhi frowned, and he could not think of any other reason. "It is possible to just cut off the left toe and pretend to be booming, or to fight."
