The Battle of Julu was the battle of Xiang Yu's fame, and it was also the turning point of the fall of the Qin Dynasty.

Looking at the historical records, the description of the battle of Julu is very brief, only a few hundred words, and the specific battle scene needs to be imagined by future generations.

Xiang Yu's army of 40,000 defeated the Qin army of 400,000, which seems incredible, but in fact, there are rules at all.

The 400,000 troops of the Qin army would not all gather together, and then encountered Xiang Yu's 40,000 Chu army, rushing up in a swarm and fighting together.

In fact, among the 400,000 troops of the Qin army, the elite troops were about 300,000, and the remaining 100,000 belonged to the second-line troops to protect grain and grass, or transport grain and grass.

This elite army of 300,000 was scattered around the giant deer, stationed in different camps, and there was a certain distance between them.

So Xiang Yu led an army of 40,000 people, and after crossing the river, he first broke the cauldron and sank the boat, which was to boost morale, because not long ago, Xiang Liang died in battle, the Qin army won successive victories, and the morale of the Chu army was low.

So, use this way to boost morale.

Then, take the lead in attacking a part of the Qin army, which may be 30,000 men. Before the arrival of reinforcements, this Qin army was defeated.

Then, he defeated a part of the Qin army, realized the scattered encirclement of the Qin army, ate it bite by bite, won nine battles and nine victories, and even killed Zhang Han.

Probably, on the overall battlefield, it was 40,000 Chu troops against 40,000 Qin troops; But on the local battlefield, it was 40,000 Chu troops against 50,000 Qin troops and 30,000 Qin troops.

In terms of battle, it may be somewhat similar to Su Yu's five battles and five victories in the Soviet Union, as a whole, it is 100,000 fruit troops against 30,000 communist troops; But on the local battlefield, it is two, three, or even four times the enemy's strength.

In the battle of the giant deer, Xiang Yu will be sports warfare, quick decisive battles, encirclement battles, etc., to the extreme, Xiang Yu's insight into the battlefield, looking for the flaws in the enemy's military formation, chiseling through the enemy's formation, chiseling, encircling, detouring, etc., to the point of being superb.

First of all, let's talk about how field warfare was carried out in ancient times.

On television, the main battle is that after the two sides meet, they rush up and kill each other, and they do exist in history, mainly the homeless army.

The elite troops who have been trained will not rush forward in a swarm, but will be divided into groups of five, some holding shields and short knives, some holding spears, some holding long knives, etc., and will form a group under the leadership of the commander to cooperate in the battle. Then there were several groups cooperating, dozens of hundred-man teams cooperating with each other.

Each other, form a close cooperation, carry out attacks.

Also in ancient times, there were no telephones, telegrams, etc., and the direction of the attack was mainly determined by the beat of drums or flags. Those low-level generals will know from the drumbeat, from the flag, the attack, the retreat, and the direction of the attack.

At the same time, after the two sides are placed in military formation, they will be divided into the middle army, the left army, the right army, and the rear army.

The rear army is the reserve.

When a certain formation collapses, or when there is a flaw in the military formation, when the support is insufficient, it will support the past and go forward to fill the loophole.

Once the reserves are exhausted, there is no moment to crush the enemy, and it is time to enter the decisive battle.

For the use of reserves, antiquity was cautious.

In ancient times, the main way to defeat the enemy's military formation was to break through the center, or to break the flank, attack its back, or cut off the military flag, or kill the general, so as to achieve victory.

The battle of Julu was mainly a field battle.

Xiang Yu used a quick assault to cut through the Qin army's military formation, divide and encircle, boldly intersperse, or outflank in a roundabout way, or beheaded the Qin generals, thus annihilating the Qin army.

It was also used to take advantage of the distance between the Qin army and the time difference, and defeated the Qin army before the reinforcements arrived.

Here, just a few simple words, which seem inconspicuous, but are an extreme test of the general's command ability, battlefield intuition, and so on.

These are all in the war books, and there is no one.

The biggest disadvantage of Sun Tzu's Art of War is that it is too high, suitable for the emperor and the marshal to read, and can cultivate their overall view.

However, for middle- and low-level officers, reading Sun Tzu's Art of War will do more harm than good, and will develop the bad habit of talking about war on paper.

For the middle and low levels, the most suitable ones are "Infantry Drill Code", Qi Jiguang's "Actual Record of Military Training", etc.

The magic of use lies in one mind.

In many moments, famous generals are fought, and they have fought continuously for more than ten years without dying on the battlefield, and they must be famous generals.

The so-called military schools, military books, etc., can train regiment commanders, division commanders, etc.; It can not train famous generals such as Bai Qi, Han Xin, Xiang Yu, and Wei Qing.

Many times, talent and intuition matter.

If you don't have enough talent, no amount of effort is useless.
