They rely on their cavalry, come and go freely, and only do one thing, that is, constantly attacking the transportation and supply lines of the Tang Army, or attacking small-scale troops and the like.

Over the past year or so, there have been almost no battles of more than 10,000 people on both sides, but battles of hundreds of people or one or two thousand people have been very frequent.

Because the protagonists of this kind of battle are cavalry on both sides, and basically nothing happens to the infantry.

As for the cavalry, although the strong charge of the cavalry of the Tang Army is very powerful, but the Tatars are not stupid, after suffering a few losses, they will not play hedging with you at all, and avoid large-scale cavalry charges.

However, in this kind of small-scale battle, many advantages of the cavalry of the Tang Army are relatively difficult to play!

But the Tang Army is not without a way to deal with it, they Tatars want to play small-scale cavalry engagements by themselves, as a passive defensive side, the Tang Army needs to deal with it, so on the one hand, they use various camouflage to disguise the main force as an ordinary grain transport team to attract the Tatars to attack, and then take the opportunity to counter and kill.

On the land side, it began to assign large-scale cavalry units to Northwest horses and some Central Asian horses, and improve the performance of war horses to gain the advantage of war horses.

In this way, it is also to let the cavalry of the two sides on the Hetao grassland fight, there is a very interesting scene, the Tatars claim to be a nation on horseback, and all the people are cavalry, but the horses they ride, especially the war horses, their quality is not as good as the cavalry troops of the Tang Empire, an agricultural nation.

The horses used by the Tatars are naturally mainly Mongolian horses, and other horses, such as war horses in Central Asia, are all in the minority, whether they are riding horses or service horses, they are mainly Mongolian horses.

But as for the horses of the Tang Army, after more than ten years of horse breeding, the Northwest horse and the Central Asian horse have entered the military service on a large scale.

Although it is said that because the army needs too many horses, even if the Tang Empire is fully engaged in cultivating horses, it is impossible to complete all the refitting in just ten years, and the traditional Mongolian horses and even the southwestern horses are not available in the army.

However, in the Ninth Army, the perennial garrison of the Hetao region, because of the perennial fighting with the Tatars, the supply of all kinds of military supplies was given priority.

Needless to say, all kinds of weapons and ammunition, even the war horse, this Ninth Army is also the first unit in the whole army to fully replace the Northwest Horse and the Central Asian Horse.

Today, the Ninth Army has two cavalry divisions, a number of independent cavalry regiments, and divisional cavalry regiments and battalions, and the total number of cavalry is more than 30,000 cavalry.

Among the 30,000 cavalry, most of the cavalry troops' main horses have been replaced by northwest horses, and some of the heavy cavalry units are all Central Asian horses, and an independent cuirassier battalion directly under the Ninth Army is equipped with Arab thoroughbreds.

In addition, the Tang Army also began to follow the Tatars, and began to give some of the main cavalry units extra horses, that is, to implement a single two-horse or even a single-horse three-horse system.

Ordinary elite light cavalry is a single horse riding two horses, while heavy cavalry is a single horse and three horses.

However, most of these auxiliary horses use Mongolian horses.

After all, those Central Asian horses and Arabian horses are actually precious things, even if the cost of self-breeding and breeding is very high, the northwest horse is lower, but it is also more expensive than the Mongolian horse.

Not to mention the cost of cultivation, even the cost of daily feeding is much higher.

In order to alleviate the logistical pressure, even in an elite main force like the Ninth Army, the army still adopts easy-to-breed Mongolian horses on a large scale!

However, in the Ninth Army, Mongolian horses are basically only used as auxiliary war horses and service horses.

As for the other troops, the Mongolian horses are still the main horses, there is no way, now these self-bred horses, the number is still relatively small, it is impossible to meet the needs of the whole army.

The horse breeding of the Tang Empire began very early, but in fact, the large-scale breeding of Northwest horses, Central Asian horses, and Arab horses was still after the occupation of the Northwest Region.

Therefore, strictly speaking, the Tang Empire began to introduce and breed the above three types of war horses on a large scale, and it was already seven years after Xuanping.

Now, exactly ten years!

In the past ten years, the horse administration department of Datang has to carry out breeding and breeding, and then expand the horse herd, and at the same time supply horses to the military, which is not an easy task, after all, horses are not cannons, not that the money is in place, and the factory can be started in a steady stream immediately.

A horse is an animal, and it takes time from the time a mare is pregnant to the time the horse reaches adulthood!

But ten years later, the horse breeding work of the Tang Empire can be regarded as a great achievement!

The military's horse administration is mainly based on many military-owned horse farms, such as Daemaying Horse Farm, Jeju Horse Farm, Liaohetao Horse Farm, etc., they mainly carry out cross-breeding and breeding, and then breed various military horses.

In addition, the Ministry of Agriculture also has a horse administration agency, they are mainly in charge of the construction of private horse administration, their horse breeding is mainly concentrated in the southwest horse and Mongolian horse and part of the northwest horse, the breeding of horses is mainly for domestic private use, especially the growing domestic transportation horse demand.

Nowadays, the Tang Empire has generally abolished the sedan chair, and the use of vehicles, whether two-wheeled carriages or four-wheeled carriages, ordinary carriages or railroad carriages, has become the main means of transportation on the road of the empire.

And these carriages all need horses!

Although in some places it is possible to use mules or even donkeys or oxen instead, this is a last resort.

In fact, because of the development of industry, the demand for horses in the private sector is greater than the military's demand for war horses.

The price of horses in the empire has more than doubled in ten years compared with the seven-year period of Xuanping, and the price of an ordinary horse can be more than 20 yuan, and even 30 yuan in some areas.

This is also a greater stimulus to the enthusiasm of the people to raise horses, do not need the official to promote, many people in the private sector will raise their own horses, even if they can't afford to use them after they are raised, but they can also be sold for money.

Because of the large number of private horses, sometimes, the military will purchase some horses from the private sector as military use, but the number is relatively small, and military horses mainly rely on the supply of military horse farms.

The cavalry units of the Ninth Army, which had a large number of Northwest horses, Central Asian horses and Arab horses, still occupied a certain advantage in the battle with the Tatar cavalry.

Otherwise, the Ninth Army of the Tang Army would not have been playing these small-scale battles with the Tatars, because although there are many Tatar cavalry and strong individual combat ability, the Tang Army is not afraid.

They had better horses and better equipment.

And more importantly, there are a lot of them!

This kind of skirmish, to put it bluntly, is a war of attrition, and no one is better than the other!

And then the Ninth Army could afford it, but the Tatars couldn't!

All kinds of equipment and materials used in operations, including horses, there is a whole empire behind the supply, guns and ammunition, and a large number of strategic materials warehouses in the back, whatever you want the Ninth Army.

Even if it is a relatively valuable material like a war horse, there is a whole empire behind it!

Even if it is a soldier, the Ninth Army and can afford it!

One soldier died in the Ninth Army, and two more soldiers could be added to the Ninth Army at any time.

However, if the Tatars die for one, there will be one less, and it will take twenty years at the earliest to be able to replenish them.

Therefore, this kind of small-scale war of attrition, which seems to have no tomorrow advantage for the Tang Army, is very advantageous for the Tang Army, because in this way, they can drag the Tatars down.

If the Tatars accompany them to continue to consume, the Tang Army will be able to drain the last drop of blood of the Tatars, and maybe it will be able to stage a 'last Tatar' drama in the future.

However, this war of attrition changed in October of the seventeenth year of Xuanping, and the Ninth Army passed a three-hundred-mile express report saying that the Tatars had made a difference!

What's the change?

The Tatars ran away!

In the early stage of the strategic offensive against the Tatar camps of the Ninth Army, which did not make a large-scale sortie, the Tatars began to withdraw from the Hetao area, and then moved to the area north of the Yellow River and south of the Yinshan Mountains on a large scale, and the signs of migration did not stop, but continued to move westward.

In addition, a Tatar cavalry of no less than 50,000 cavalry, when the Tatar tribes migrated, stationed troops in the south of Yinshan, or more precisely, about twenty kilometers northwest of Dongshengcheng.

However, this cavalry did not continue to march towards Dongshengcheng, nor did it march to the two newly built fortresses north of Dongshengcheng, and the Ninth Army guessed that the 50,000 Tatar cavalry was not intended to attack Dongshengcheng.

They should be guarding against the Tang cavalry in Dongsheng City to attack and attack the tribe they are migrating.

The Tatars were about to run away, and this scene was almost incomprehensible to the commander-in-chief of the Ninth Army.

You must know that in the past few years, although the brains of the Ninth Army and the Tatars have come out, even the Ninth Army has made the Hetao defense line.

However, the Tatars still did not completely abandon the Hetao, and basically stayed in the Hetao area for grazing every year, at most in some areas away from the Hetao's defense line.

As for the Ninth Army, basically, it would send cavalry units to attack frequently, sometimes attacking their camps, and then capturing a large number of horses and livestock, etc., and sometimes, purely to set fire to the grass, so that the Tatars would not have enough grass to survive the winter in the autumn and winter.

The Tatars attacked the supply lines of the Ninth Army, and the Ninth Army attacked their pastures.

But now, the Tatars have suddenly withdrawn from the Loop, what does this mean?

This means that the Tatars finally could not hold out in this war of attrition, they confessed and ran away!

As soon as it was discovered that the Tatars withdrew from the loop and began to move westward

The Ninth Army immediately flew to Jinling City.

In addition to the report, the Ninth Army also asked Jinling for instructions, what should I do next? Sit back and watch them evacuate from the Hetao, or take the opportunity to kill a wave and cut down the grass and eradicate the roots!
