The speed at which the Han army built the defense line was absolutely superb, and by the time the Romans finally gathered more than 50 legions and marched to the camp of the Han army, the Han army was already in full array.

It was too late to dig the trenches, but the soldiers in the first row still dug themselves a shallow position for individual shooting, at least they could shoot from their stomachs.

The Han army discharged a long line of skirmishers, and the Romans also drew their own legions and barbarian armies into a long line of attack in order to attack in place.

This happened to fall into Ma Chao's strategy, because the Han army's rifles had a fast firing speed and a high density of firepower per unit area, while the main force of the Romans was still a front-loading rifled gun, which could not fire horizontally and had a slow loading speed.

It was supposed to use a dense formation, relying on the density of fire to compensate for the lack of accuracy, but it was dispersed into a long skirmish line and lost its advantage.

The main reason for this is that coach Lucis is not adapted to the war in the firearms era at all, does not understand his own shortcomings, and does not understand the advantages of the other party, and is led by Ma Chao.

Relying on his superiority in numbers, Lucis attacked first, with the hoplites of the auxiliary corps holding their shields in the first row, and the musketeers of the Roman legions and auxiliary corps following behind the shields, using the shields as cover.

The barbarian army was assigned to attack the left flank of the Han army, the position of the Persians.

Lucis's idea was that his weak part would fight against the weak part of the Han army, and it made sense.

The barbarian army of 60,000 was half cavalry and half crossbowmen, so they attacked faster and advanced faster than the Romans.

Therefore, on the entire battlefield, the left flank of the Han army and the right flank of the Romans collided first, and the army of the Persian Empire also had 20,000 cavalry, and the cavalry was also the capital of the Persian Empire, and the cavalry was also attached great importance to it.

Although firearms have been popularized, the traditional Persian cavalry has also been preserved and developed, and the 20,000 Persian cavalry brought by Prince Shapur are all traditional armored cavalry, similar to heavy armored cavalry, except that the armor on the knights and war horses is lighter.

Among the 30,000 cavalry of the barbarians, it was composed of 10,000 heavy armored cavalry and 20,000 light cavalry.

These heavy cavalrymen were from the Frankish tribes, riding tall horses and holding a three-foot long cavalry spear.

The barbarians were not equipped with any firearms, but still used primitive cold weapons, spears, cavalry spears, and swords were the weapons of these cavalry.

The 30,000 crossbowmen in the back, all dressed in light leather armor, half of them wielded longbows and half of them wielded crossbows.

Although Prince Shapur did not study at the military academy of the Han Army, he was also trained by Fazheng and had mastered the tactics of using firearms.

In the face of these fierce enemies, he had already made a plan.

Among the 30,000 Persian infantry, there were 10,000 heavily armed shieldmen, who were placed in the first row, and behind them were 20,000 Persian infantry armed with rifles.

Prince Shapur did not use cavalry and barbarian cavalry to hedge, but calmly met the cavalry charge with infantry.

The middle and lower rank officers of the Persian Army shouted loudly, "Steady! Don't be afraid, hold on, they can't rush close! ”

The heavily armed shield-bearer, leaning sideways, his feet firmly planted on the ground, waited for the onslaught of the barbarian cavalry.

Prince Shapur strictly followed the Han army's infantry drill to arrange his tactics, and he ordered the musketeers in the second row to fire a salvo to cover the shield bearers in the first row.

The muskets used by the Persian army were basically comparable to those of the Roman legions, also front-loading rifled guns.

However, the barbarian cavalry did not have muskets, only light cavalry was equipped with hunting bows, so when the Persian army fired a volley, they could only be helpless.

The most fatal thing is that the Persian army is equipped with artillery regiments, and the Persian artillery has carried out fierce artillery bombardment on the barbarian cavalry, and many heavy cavalry have never heard the sound of artillery at all.

They were all startled by the loud sound of the artillery, and the horses under their crotches were not trained in this area, and many of the horses were startled and jumped around, and some of the knights were dismounted.

Although the light cavalry had hunting bows, they had a limited range and could only stare at artillery fire and salvos, and rush to within 60 zhang before they could counterattack.

Pieces and rows of barbarian cavalry were put down, and corpses were strewn all over the field.

Most of the barbarian cavalry, who were lucky enough to rush to the Persian Empire's military formation, were tired, and they mustered up their courage and slammed their horses into their shields.

The hoplites behind the shield are often knocked out and vomit blood, and they start firing freely when they shoot at close range.

When the barbarian cavalry was a little exhausted and the losses were increasing, Prince Shapur ordered his cavalry to attack, outflanking from both flanks and inserting between the barbarian cavalry and the barbarian crossbowmen.

The recuperated mounted cavalry suddenly appeared on the flanks of the barbarian cavalry and thrust into the enemy's ribs.

Moreover, the Persian army was also equipped with a lot of grenades, and the explosion at close range seriously injured the barbarian cavalry.

Before the order to retreat sounded, the barbarian cavalry was torn apart, some ran back to their own front, and some directly withdrew from the battlefield.

Having scattered the barbarian cavalry, the Persian cavalry rushed to the barbarian crossbowmen behind.

Although it soon entered the range of barbarian crossbowmen, the Persian cavalry were armored cavalry, and had strong protection against the shots of these crossbowmen.

At this time, a fatal flaw of the barbarian army became apparent, that is, there was no infantry, and behind the cavalry were crossbowmen, and when the cavalry was dispersed, the crossbowmen became lambs to the slaughter.

The Persian cavalry rushed into the ranks of barbarian crossbowmen, like chopping melons and vegetables, killing the enemy to the ground, and the left flank of the Han army was already a solid victory.

At this time, the attack in the middle also entered a critical time, and the Romans blocked the front with heavy shields of auxiliary legions, just to resist the fire of the Han army.

However, the first thing the Han army launched was an overwhelming artillery bombardment, mortars and field artillery, the density of artillery fire was greater than before, and the heavy shield soldiers could block the front and could not block the overhead, and they felt a little careless.

Moreover, the Han army deliberately put them into the range of the rifle before starting the shelling, which was really a two-pronged attack.

Although the Romans quickly remembered to use their own artillery for cover, they were too late to strike.

The artillery of this era had a relatively short range, and they could only hit the front of their own front, at most suppressing the opponent's forward positions, but they could not deal with the opponent's artillery.

The two sides could only compare whose artillery cover was more powerful, and the forward infantry of each other fired at each other.

The Romans were on the attacking side, so they had to take the initiative to attack, advance under artillery fire, and only when they charged in front of the Han positions would the Han artillery shelling extend to the rear so as not to be accidentally injured.

Just when a large number of Roman infantry, after firing a round of bullets, began to load muskets with bayonets, and prepared for hand-to-hand combat, the Han troops in the first row began to retreat, and the Han infantry in the kneeling position in the second row also turned and retreated.

The Han troops in the first two rows retreated one after another, revealing a row of big guys who had been hiding behind them.

This big guy is a bit like a cannon with two wheels, with ten rifles in the middle forming a cylindrical shape, of course, only the barrel part in front of the rifle, and no firing mechanism in the back.

Three Han infantry squatted behind this monster, and after the Han officer gave the order to fire, one of them would start to shake the handle, and at this time, ten barrels around the central column began to rotate rapidly, and a continuous sound of gunfire came.

The handle shook faster and faster, and the gunshots became more and more dense. Da. It became a da-da-da. Da-da-da-da.

There is also a Han infantry next to it holding a row of bullets that will be refilled from the top of the new weapon.

A dense stream of bullets would rain down on the Roman soldiers in front of them from the new weapons, like dozens of rifles firing at the same time, and the Romans would fall in row.
