The 10,000 lightly armored cavalry of Kangju held small round shields and formed a loose formation to charge the Han army, which was already the most effective method they could think of.

Use a small round shield to protect the vital points, and the loose formation can exchange space for time.

On the premise of not using mortars, the Han army really had no better way to deal with the Kangju people.

The Western Regions Coalition Army is purely a decoration, and when defending, it is useless.

When the repeater crossbow encountered the Kangju cavalry, which was protected by light armor and a small shield, the effect was not particularly obvious.

The 7th Cavalry Division did not have an artillery battalion, and although the artillery battalion of the 6th Division was lent to them, Fa Zheng believed that the 10,000-man enemy was not worth using mortars to charge.

Therefore, the Seventh Cavalry Division still mainly uses crossbows, but because the Kangju cavalry needs to use a small round shield to protect their bodies, they also have no way to attack with a hunting bow, which has advantages and disadvantages.

They could only rush to the Han army's defense line with rain-like crossbow arrows all the way, but they were also very heroic.

However, mortars are not allowed to be used, and grenades can still be used, and at thirty zhang, the grenades that fall like raindrops are still enough for Kangju people to drink a pot.

The small shield can protect people but not horses, not to mention that some fragments can still cut through the protection of the small round shield, and some unlucky eggs are directly hit by grenades, blown to pieces, missing arms and legs.

The Kangju army rushed into the Han army's formation, and Guan Hai ordered the Western Regions coalition army behind him to attack and besiege the enemy with the Han army.

Although he can't afford to take the responsibility of attacking head-on, it's still okay to kill two Kangju people.

The Han army's halberds and Mo knives skillfully harvested the heads of the enemy, and the Mo knife was used to deal with the enemy's better and better armor protection.

King Kangju saw the power of the grenade with his own eyes, and sure enough, it would explode with a loud bang and a large amount of smoke.

And the damage to the war horse is much greater than that to people, but it is still within the range of what he can bear, and the power of gunpowder seems to be no more than that.

He also saw that half of the Han army camp on the opposite side was a coalition army of the Western Regions in disheveled clothes, and the main force was the army of the Wusun people.

Kangju has dominated Central Asia for so many years, and he knows too much about the combat power of the countries in the Western Regions.

Except for a few countries such as Wusun, Shule, and Shache, the countries of the Western Regions are still martial, and the rest are a rabble.

His real opponent is only these 70,000 or 80,000 Han troops who can fight, and there is also Prince Alain's garrison army in the city, and he can also rush out to flank the enemy army at a critical moment.

He secretly sent people into the city through a secret passage to deliver a message, and Samarkand, as the historical capital, naturally had a secret passage leading directly to the outside of the city, in case of emergency.

The secret passage is narrow, and it is unrealistic to want to pass through the army, but it is still okay to send a letter.

Having made up his mind, King Kangju ordered his entire army to attack and lift the siege of Samarkand before sunset.

He asked the Huns to attack with him, at least to contain the Han army on their side.

The Huns promised that as long as the Kangju people attacked with all their might, they would also attack with the whole army and drag the left side of the Han army.

The melodious horn sounded, and the Kangju army began to press forward as a whole, and the 20,000 hoplites in the middle slowly stepped forward with their large shields.

They lowered their shields every ten paces and waited for the archers to follow, followed by 20,000 longbow cavalry.

On the left flank of the Kangju army were tens of thousands of ordinary light cavalry, also armed with small round shields in front and hunting bows in the back.

The team spread out as much as possible, and dozens of horizontal lines were discharged.

The Huns saw that the main force of Kangju in the middle of the road was really dispatched, and they no longer delayed.

King Zuo Xian ordered the three commanders, commanding the 30,000 Hun cavalry under their respective commands, to also spread out the formation and trot forward.

The Kangju people kept a hand on them and did not tell their subordinates to use small round shields to protect themselves, so the Hun cavalry still had only leather armor and simple iron armor protection.

Seeing that the enemy army had finally begun a full-scale attack, although it was expected, it was still nervous.

Even the people of Kangju know that the Western Regions Alliance is unreliable, how can Fa Zheng and the others not know?

To put it bluntly, they are just used to fill the numbers, the icing on the cake, and they have never been expected to be used as the main force.

Fa Zheng asked the 1st Cavalry Division to be careful of a sudden attack by the enemy forces in the city.

Only then did he turn his attention back to the front, this time by the play of the artillery battalion.

Fortunately, the Protectorate of the Western Regions rebuilt the Silk Road, hoarded a large amount of military supplies, and of course spent astronomical amounts of financial revenue.

However, as long as these important countries of Central Asia can be occupied, slaves, livestock, and minerals have a lot of resources that can be rewarded.

Anyway, it's not your own people and hometown, and you don't have the slightest scruples about fishing with all your might.

It is as if after the occupation of the Dawan Kingdom, the sweaty BMW was almost sent back to the horse farm directly under the Central Army in the Ili River Valley.

The gold mines of Dawan have also increased tenfold, and the gold harvested every day is enough to feed many armies.

However, the Protectorate of the Western Regions has brought rare geological experts from the Imperial Capital University Hall in Chang'an, who will survey the countries of the Western Regions for any minerals needed by the Han army.

The consumption and actual use of the army have also promoted the production of military industry, for example, the Central Army began to equip with firearms, and the scale of gunpowder production has doubled, and saltpeter, the raw material for making gunpowder, is in short supply.

Fortunately, Lu Bu remembered the nitrate field method, and after several experiments, he finally found a reliable nitrate field method.

This ensured the production of gunpowder, and the mining of iron ore and coal exceeded that of the past.

The scale of the iron-smelting plant was also expanding, and Ma Jun's invention made it possible for water to replace valuable manpower in many cases.

The Han army's request to the Western Regions Coalition Army is not to panic, the first half of the queue is the Han Army, the Western Regions Coalition Army is sandwiched in the middle, and behind it is also the Han Army with a crossbow and a tiger's eye.

Fortunately, it was the 6th Division that defended the center, all of which were infantry, and there were also four or five thousand hoplites themselves.

And behind them there were artillery battalions of special operations divisions and their own ballistae.

The infantry division also retained the armament of the beaded ballista, and in order to deal with the chain armor, each infantry battalion was equipped with six beaded ballistae with a range of 150 zhang.

They patiently waited for the artillery battalion to be the first to attack, and when they were still at the maximum range of 200 zhang, the mortars began to suppress fire.

The sound of "bang" and "bang" was incessant, and shells exploded in the hoplite group.

Although they were heavily armoured, the casualty ratio was much lower than that of cavalry.

But blowing down their shield gave the ballista a chance to play.

Following the gaps exposed by the fallen shield, one crossbow arrow after another accurately hit Kangjuguo's hoplites.

The shooters of the Lianzhu ballista are all selected, and the accuracy rate is extremely high.
