The cow saw the tiger squatting in the pine forest by the river, without saying a word, like a sculpture.

Outside the forest.

The Nantan River passes through a canyon here, and a small road following the valley at the foot of the valley winds along the river. This is a road less than ten feet wide.

A military officer came to Niu Jianhu.

"Nong Tianshun is coming here for 12,000 troops."

"Be more specific." Niu Jianhu looked serious.

The army quickly pulled out a dagger and gestured on the ground, "Nong Tianshun has two thousand men, including stairs and cavalry, but they are basically young and strong men. They do not carry any old, weak, women and children, nor do they carry supplies, only some horses and mules accompany the army."

"They are about two thousand people in one battalion, with five stairs and another cavalry battalion."

Niu Jianhu quickly calculated, "The road is narrow, and each battalion walks in two people in one battalion. The road is 1 zhang wide, and then four people are in a row. The road is 1 zhang wide, six people are in a row, two zhang wide, and eight people are in a row..." The road Niu Jianhu mentioned does not refer to the road surface commonly referred to, but refers to the ground that can be walked on the left and right of the road, which is calculated and arranged in the width of the road.

Marine is a very complicated thing. One key thing is the length and path of the marching. In short, when marching, you must first make the number of people, cars and horses in each row, as well as the distance between the front and back, and the distance between the troops according to the width and narrowness of the road. You must also arrange reconnaissance, horse exploration, cavalry patrol, etc. accordingly.

Just like when Yang Guang conquered Goguryeo, he sent 1.12 million troops, divided into three routes, and two left and right routes were organized into twelve armies, plus a large number of auxiliary troops and grain transporters, he sent one army every day, forty miles apart. It took him forty days. All the troops had just finished their departure. The troops were connected from head to tail, and more than nine hundred and sixty miles in front and back.

This is the marching distance of a million troops, which is thousands of miles high and very terrifying.

Niu Jianhu, as the second generation of generals, is also familiar with military tactics and has been practicing in the army for a long time, and is quite clear about these.

Taking the road by the river in front of you? Come from Bozhou? Nong Tiangui's soldiers can only have four people in a row at most? If they are cavalry, they can only have two cavalry.

There are strict standards for the marching of soldiers in the Tang Dynasty. For example, the distance between infantry hiking rows is seven feet, and the distance between cavalry traversing rows is ten feet two feet.

There are 200 infantry soldiers in the palace? Not counting the logistics mule and horse carriage convoy, the length of the marching is 33 meters, while the length of the marching is about one mile for an infantry battalion of 800 people.

If it is a camp of two thousand people? The radius of the marching is three miles.

Of course? If it is an elite unit? The distance between infantry can be shortened to one step? That is about 1.5 meters.

Based on this data, Niu Jianhu could quickly infer the length of the 12,000 team of Nong Tianshun? He had five infantry battalions and ten thousand people. If the five battalions did not set a distance to march together, it would be 10,000 to 4, one step, two,500 steps, five hundred steps per mile? Then he would have to set up a five-mile long team.

In addition, two thousand cavalrymen are? Two thousand are divided into two times one step? It is another two miles long.

These 12,000 people? Even if the middle of each battalion is not separated, it will have to be six miles long.

And in the canyon passing through this nearby, the road surface is less than one meter wide? This means that the team will be doubled, which is at least twelve miles long.

At normal marching speed, marching about ten miles per hour means that the distance between the rear army and the front army is more than one hour.

Of course, these data are based on the data of elite Tang army soldiers. In fact, there are both Jucheng and Zuoxi barbarians in Nong Tianshun's barbarians. They were not professional troops, but were joined by various tribes and rivers. They were originally made up of hunters, blacksmiths, silversmiths, miners, farmers, slaves, etc.

Such an army will definitely not maintain a good understanding when marching, especially between the troops, which will inevitably be distanced.

Especially when passing through some dangerous sections, it may also cause congestion, etc.

In order to ensure that the army is not confused when it is marching, the Tang army has always asked to marches on the road, rest in a row for ten miles, dry food for thirty miles, and food and accommodation for 60 miles.

Otherwise, as you walk, a large number of soldiers may fall behind. You must keep resting and recuperating to lead the troops and maintain combat effectiveness.

The larger the troops and the more troops, the slower the marching speed, because the team has to be organized along the way.

After doing this, although Nong Tianshun's 12,000 troops were considered elite vanguards of the barbarian army, it is estimated that it would take about fifteen miles or even twenty miles to go along.

The real one-line long snake formation.

The cow saw a tiger slashing on the ground, a long curved line.

"This is the Wanda River, this is the Thunder Cloud Valley."

The canyon in the Thunder Cloud Valley is more than ten miles wide. The Nantan River exits the Thunder Cloud Valley and merges into three tributaries. Then it turns a big bend to the northwest. Therefore, after leaving the canyon, it has to cross the river.

The Nantan River is not very wide, but it has a lot of rain recently and the river is quite deep. Although you don’t need to build bridges and ships, you must be careful to cross the river, after all, you can reach your chest in the depths.

Some dark pits can even cover the top of the head.

Niu saw that Hu brought three thousand people to him, and the other party was 12,000.

"We can attack halfway, first let Nong Tianshun pass one-third of the troops, or half of them, and then we suddenly attacked and caught him off guard, and then wiped out half of his troops on the north bank." One of the soldiers suggested.

"The opponent's long snake formation is a long character. Let's cut the snake seven inches. First, let the snake heads of one-third of the people pass by, and then we cut the second half from it, divide and surround it, and annihilate them one by one!"

Some of the military members believed that their mission was to block Nong Tianshun's vanguard barbarian army and to buy time for Qin to use the general to attack Wen Mankou, so it was enough to attack halfway and knock down the opponent's snake head, so it would be enough to ensure that they would not be damaged too much.

After all, if all three thousand soldiers are placed on the north bank, they can support each other. If they are divided into several soldiers and ambushed separately, although they can cut off the enemy, they will be relatively dispersed, and they will easily be outnumbered and are more dangerous.

"Nong Tiangui is just a vanguard. If you really want to defend Jingxi Prefecture, you have to be able to withstand Nong Sanniang and his 50,000 or 60,000 troops. We have to preserve our strength and not easily lose it."

Several of the military members expressed their opinions.

The cow sees the tiger pondering.

Qin Lang attached importance to intelligence collection and analysis, tactical formulation, etc., so he specially set up the Military Intelligence Department, Staff Office and Operations Department, and selected a group of experienced officers to join the army, Staff Office praised paintings, and provided a lot of help to the main generals.

He not only helped his camp to join the army, but also made all officers at all levels below to work together.

Of course, this will also lead to a small problem, which is that there are too many opinions, which will test the leader's ability to make decisions.

There were 3,000 people in Niu Jianhu, but these 3,000 people were not all from the South China Sea Fleet, nor were they the elite of the Marine Corps. Only some of the elite of his Marine Corps were the first to land at Taiping Port and scattered to Zhennanguan, Shixi, Xiping, Gaoping and other places. He took him to Jiaozhou, and then went up the Jinjiang River, mainly the sailors of the fleet, as well as some of the Jiaozhou Township Braves and Mandings assigned to him by Li Daliang.

After arriving in Ping Meng, he got some Gaopingtun Ding, Wu'anzhou Township Warriors, and even many young men. In general, his three thousand men were very mixed.

Fortunately, after fighting some battles, I cooperated with each other tacitly, especially since I had seen blood, they were still brave enough to fight. In terms of equipment, they were OK, but to be honest, after all, they were all made up, far worse than regular government soldiers.

Whether it is equipment, military quality, training, etc., they are much worse.

If there were three thousand elite soldiers in the palace, Niu saw the tiger without thinking too much. He would just lie in ambushing the canyon, and then rushed out and cut the rebels into pieces and cut them hard.

"Generals and barbarians are all chaotic, and they are even more messy. And now they are in a big defeat. It is a time when people are panicking. The soldiers have no morale. On the contrary, we have won all the battles. Now we are in a strong morale and the morale of the army is available. I think we can completely feel at ease and boldly divide the troops into several ambush rebels......"

His reason was that the canyon was very narrow and the road was wide enough to allow only a few people to march. This meant that even if the barbarians had 12,000 troops, they could not be used in the canyon, especially their two thousand cavalry, which was even more useless and had no need to be afraid.

Don’t say 12,000, or 120,000, you can’t use it in this terrain.

Therefore, even if the Tang army was divided into groups of 200 people, they only faced a few enemies when they rushed down from the mountain, and they could even form superior forces.

When the enemy's long snake formation is cut off, the head and tail are even more inseparable from each other.

By using points to cut the line, of course, the Tang army has more advantages.

The barbarian vanguard crossed the Nongtan River, but the rear army had not yet entered the canyon.

"We ambushed a army here in Nantan River. When one-third of them crossed the river, they covered and attacked halfway, and first cut the snake's head. Then at the same time, let the brothers ambush at the east entrance of the canyon kill, blocking the entrance of the valley with wood and stones, and cutting off the barbarian's tail outside the valley......"

In the pine forest, the ground was densely covered by the soldiers.

The eyes of the cow are getting brighter and brighter when he sees the tiger.

"Very good. Let's concentrate our 800 cavalry and put them on the north bank of the Nantan River. When the other party's snake head crosses the river, the eight hundred brothers attack and chop off the snake head."

There were two thousand and two hundred people left. Niu Jianhu divided it into eleven groups according to a group of 200 people and a group of eleven groups, and arranged them to enter the Ten Mile Canyon and ambush them separately.

"It is agreed to take beacon as a sign, and the beacon smoke rises and attack at the same time!"

Three thousand people beat 12,000 people, and none of them are elite. But when we meet on the road of the gorge, in addition to the brave, we have to rely on strategies and plots.

After analyzing, the cow saw the tiger's confidence increased greatly. Although the barbarian army was numerous, in this terrain, they lined up with snakes, and had to be pulled to more than fifteen miles or even twenty miles. As long as they had a fast sword, it was difficult for the barbarians to connect heads and tails. With the special geographical advantage of the canyon, even if the barbarians wanted to look at each other from beginning to end, it would be impossible.
