The delay in the arrival of the Zhijun made Du Ruixun extremely passive, so he had to use all his resources to drag the Xianjun army:

"How's the digging of roads and trenches going?"

"General Hui Du is digging up roads with all his might to slow down the westward advance of the Xian army."

"Continue to speed up, and if necessary, dig rivers and dikes to stop the Xian army from advancing westward."

Du Ruixun expected that the Xian army would cross the cities of Dekang with superior forces, occupy the key points first, and open up the westward passage, so he ordered people to dig the road and dig trenches on the roads that must be passed in the westward march to delay the westward advance of the Xian cavalry.

By the morning of the next day, the Xian army on the west bank of the Sishui River was close to 700,000, the Third Group Army had all crossed the river, and the Second Army had crossed more than half of them.

It was only one night, and the Huwei River was more than 100 miles from north to south, and from east to west for 30 miles, and he could not imagine how the Xian army could erect hundreds of thousands of barracks in two days and one night on a front that was 100 miles long and 30 miles wide.

In order to increase the transport capacity, the implementation of one-way traffic, the morning from east to west across the river, in the afternoon empty cars and horses from west to east traffic, at the same time the first pontoon bridge north of the two miles of the river, began to erect the second pontoon bridge. By the evening of the same day, the number of Xian troops on the west bank had increased to more than 800,000.

At the same time, Ye Xin led the Third Town Army to bypass the Huwei River and assault westward, while Lu Gao's Second Group Army Mo Yunfeng directly attacked Jianyutan, Jiangquan, and Tingshan, and Lu Gao and Guan Longxiang led the Guzhong Fifth Town Army to make a detour to the south, bypassing the Huwei River to cut off the northward passage of the Zhi Army, and at the same time posing a posture of encircling Du Ruixun.

On the same day, the Xian army did not shell the guard camp west of the Huwei River, but Baili Yan transferred Xu Jin's department, marched north with Ye Xin's department, bypassed the Huwei River and detoured from the north flank, and detoured with the south flank to the central part to form a north-south flank and encirclement.

By dusk in the afternoon, Ye Xin led his troops all the way unimpeded, and the trench dug by Du Ruixun did not play any role, and the reason was incredible:

"What, there's such a thing!"

"Yes, the great general, the Xian army will put a large iron bar two or even three zhang long on the trench, and then lay an iron plate, and erect a wooden stake under the trench, so that the people and horses can pass through the iron plate unimpeded, not to mention half a day, or even an hour to open the trench and continue to advance."

The scout said quickly, Du Ruixun's eyes were dizzy, and now he fell to the ground:

"Oh my God...... This is to destroy my country...... Uh-a-ah......"

After a sad wail, Du Ruixun fell unconscious in front of the table.

It turned out that Bailiyan had to report that the guards were digging trenches early in the morning, so he mobilized steel rails, iron plates, and logs early in the morning, and asked Ye Xin to carry them with the army, which is also the main reason for slowing down the passage of personnel and speeding up the delivery of materials today.

It is not that Du Ruixun knew that he was going to dig trenches to delay the westward advance of the Xian army, but that the current agricultural irrigation has dug a water diversion canal, with a width of three to ten meters, crisscrossing all over the place, and the density of agricultural irrigation facilities is greater than that of modern times, and this kind of water diversion canal either leads to the river or leads to the river, which is dug from a high position, so it cannot be filled with silt, otherwise it will cause a dam, and then flood, so it can only be bridged through.

However, it takes a long time to erect wooden bridges, the bearing capacity is low, and the whole life is short, even if the structure is strengthened, all the way to repair, each bridge is only ten meters, but it takes a whole day to repair, which is undoubtedly a waste of time and delays the fighter. To this end, Bailiyan transported a batch of storage rails and five millimeters of homogeneous rolled steel plate to the front line for backup.

At present, there are two specifications of steel rails, one is about 3.5 stones per zhang, which is about 3.5 stones per zhang (less than 75 kilograms per meter), and the second is three zhang long, which is about 2.3 stones per zhang (about 50 kilograms per meter), and a four-wheeled baggage vehicle can be equipped with ten heavy rails, or thirteen light rails.

The hot-rolled plate uses a square plate with a thickness of five millimeters and a width of one zhang and a half and a zhang long, which is erected in the middle of two rails when laid, and the logs are supported under the rails for support.

At present, the cavalry is extremely developed, and the princes of all countries have the tactics and tactics to restrain the cavalry, and digging trenches is only one of the passive means of defense. But Du Ruixun would never have dreamed that the Xian army would use rails and steel plates to lay bridges, and the purpose of delaying the Xian army could not be achieved, and the guards west of the Huwei River were simultaneously surrounded by the Xian army in the north and south.

Under the agrarian civilization, war is only a crude and monotonous mode of war, the system is weak and the planning is not strong, there are only strategic goals, but there are no quantitative action indicators, even if you meet a genius who has not met in a century, it is only the glory of a generation, there is no systematic cultivation and inheritance, let alone open up new fields.

The modern war machine, on the other hand, places more emphasis on organization, planning, and system building, and the general's function is more specific, without the need to distract more energy from complex and complicated and even trivial matters.

All these will be handed over to the departments of the General Staff Department, the General Logistics Department, and the Intelligence Department at all levels to operate on their own, draw up plans and plans, and write reports and submit them to the supervisors. This greatly freed up the general's energy and made him more focused on the war situation.

At the same time, the decentralization of power, systematization, and institutionalization has well cultivated and inherited the traditions and skills of the military, so that it can adapt to the changes of the times, and constantly iterate to create new ones and be determined to carry out reforms. At this point in the war, the defeat of the Guards was assured.

In the second half of the night, the guards were in chaos, the guards were in chaos, and the Xian army was divided into two flanks from the north and south, almost cutting off the retreat to the west, and the speed was beyond the reach of the guards.

The next day, Bai Liyan led the Third Army to the west, and Xu Jin's troops temporarily left Du Ruixun's northern flank to continue to complete the encirclement, and waited for Zhao Xun's First Army to cross the river and then change the defense.

At noon on the same day, the guards broke through to the west, but were intercepted by the cavalry of the Xian army, and the two armies fought a fierce battle, each with casualties. The artillery of the Xian army carried out artillery bombardment on the westward fleeing guards, but did not bombard the guard camp to avoid greater casualties, and at the same time sent into the guard camp to persuade Du Ruixun to surrender.

As a result, the luck of the Xianjun soldiers on the envoy was not as good as Su Ke, and he was directly beheaded by the guards and hung in front of the camp gate.

In the afternoon of the same day, the vanguard of the Zhi Army entered Iwaki, and the Dayandang and Iwaki guards rushed to Du Ruixun's aid. At the same time, the other line of Zhi army went straight to Taiqin, but the Xian army took the first step to surround Taiqin, and the Zhi army was blocked.

In late October, Ye Xin led the Third Town Army to the border of Dekang and Yuanshan to establish a defensive line, and successively engaged the westward fleeing guards, either driven away or surrendered. By the end of October, the Third Group Army had gathered heavy troops, two-thirds of Dekang had fallen into the hands of the Xian Army, and Du Ruixun's headquarters and main force of about 300,000 people had been surrounded by 700,000 people of the two group armies of the Xian Army in three places.

At the beginning of November, the front-line good news arrived at the Lingling:

"Great victory, great victory of Dekang!"

Jiao Muhua shouted loudly by holding the good news, and quickly rushed into the corridor by Bailing Lake, King Xian was overjoyed when he heard the news, got up and stepped forward to grab the good news, confirmed that the secret letter was intact, and then removed the fire paint and took out the good news, and the next moment couldn't help but close his eyes and burst into tears:

"Win, our army won!"

According to the war report, at the end of October, 250,000 guards were killed, wounded, captured, and surrendered, 13 cities were gained, 27 cities were besieged, 300,000 guards were besieged, 120,000 war horses and pack horses were obtained, and 4.2 million stone grain in Taiqin and Yefeng granaries fell into the hands of the Xian army.

"Jiao Muhua, quickly order Zhang You, Nuo Yiyan, Gao Xun and the crown prince to go to Guangyuan Hall to wait, and pass when there are few people."

"The last will obey."

After Jiao Muhua left, King Xian could not hide his maneuver, walked back to the corridor and held the concubine in his hand and said:

"Aifei, our army has won a big victory, our army has won a big victory."

Concubine Zhen was very happy to hear the news, and she said:

"The king governs the country well, and with Zhao, Lu, and Baili who can conquer the generals who are accustomed to fighting, our army will definitely be able to win."

"Hehehaha, what Concubine Ai said is very true. Come, have another drink with the widow. ”

King Xian picked up the wine boiled on the stove and gave it to Concubine Zhen, and each person ate it all in one bowl.

In the afternoon of the same day, the news of the complete victory of the Xian army entered the prince's mansion through the palace, and Xihuan heard the news like five thunders and the end of the world was unbelievable:

"What, the guards lost 250,000 people, is it mistaken, is it 25,000 or 125,000!"

"Back to Her Royal Highness the Princess, the prince is really telling the truth, it is 250,000 people. The subordinates repeatedly asked and confirmed, and there would be no mistakes. ”

Ji Ning said affirmatively, Ji Jinsheng and Gu Chen's faces on the side were like ashes, which was no less than a heavy blow to the head.

"How is this possible, even 250,000 pigs, which is enough for the Xian army to kill for a year and a half, how can it be severely damaged by the Xian army in half a month. What's more, how powerful the guards are, how can they be so vulnerable! Xihuan couldn't believe that the 250,000 guards were annihilated by the Xian army in half a month, so he looked at Ji Jinsheng and said: "General Ji, could it be that Zhao Xun Bailiyan lied about the military situation to deceive the world!" ”

Ji Jinsheng was taken aback when he heard the news, and he hurriedly said:

"Your Royal Highness Princess, if you encounter 50,000 enemies in an ordinary encounter, it may be an exaggeration, but now it is 250,000 guards, once the news comes out, if it is not true, how can it be so simple to lie about the military situation, it is a matter of national prestige and military prestige, the general is cautious, how can he lie about the results of the 250,000 battle."

Under the conditions of agricultural technology, the scale of warfare is constrained by logistics, roads, battlefields, and communications command, and it is impossible for the scale of troops in a main battlefield to rise to one million.

Even if the main force is decisive in a field battle, the total strength of the two sides rarely exceeds 300,000 in a main battlefield, usually only 100,000 to 150,000, and at most 200,000. The so-called million-strong army cannot be concentrated in one battlefield or even one exhibition area, and the troops are distributed in various battlefields and dispatched by different commanders.

Therefore, one-third of the casualties on one side of the troops in a field battle are enough to demoralize the army, and the retreat to the camp is not fighting, and the detailed data, that is, more than 10,000 to 20,000 casualties, can make a 100,000-strong army retreat or even be defeated.

A very small number of veteran regiments with a firm will to fight and strong organizational ability can withstand losses of 40 to 60 percent, and it is extremely rare to have a decisive battle with cold weapons that fights to the death to the end and the entire army is annihilated.

On the eve of Du Ruixun's launch, the main force was arranged along the river, focusing on fortifications in six places, and the troop allocation of each battlefield did not exceed 150,000.

According to the traditional routine, even if the Xian army wins or loses in a field battle, the 40,000 or 50,000 wounded guards are already an unprecedented victory, and adding 100,000 people with some water is scary enough.
