Baghdad east of the Tigris River and the city of Habania west of the Euphrates River are separated by two great rivers, and the importance of geographical location can be imagined. Pen, fun, pavilion www. biquge。 info

Before the fall of Baghdad, the Habanian garrison Muhammad Jimmam Zachi received a notice, and unexpectedly, three days later, the sergeant 100,000 hurriedly reported to him: "The Tang people are coming, on the other side!" ”

Zachihuran stood up!

He wasn't afraid, but he was surprised by the speed with which the Tang people arrived, he knew that the two city guards in front of him were very resolute main battle factions, why didn't they even intercept it at all?

The situation is grim, and the main generals sent by the big cannibals to defend the city are all generals, and the military leaders who fight old battles are by no means those gold-plated silver wax spear heads.

Zaci was one of them, who had fought against Constantine in North Africa, and when he heard that the Tang had arrived on the other side, he issued an order to send the city's troops to the Euphrates River to resist. "The Tang people are coming!"

"Pick up your weapons and assemble your team!"

Although the soldiers and civilians in the city were panicked, they did not panic, and in accordance with the combat strategy prescribed in advance, some went to the city to assist in the defense, and some participated in the assembly and prepared for battle.

Prepared in advance, Zachi handed over the military affairs to the adjutant general, took five hundred cavalry with him, mounted his horses, and galloped out of the city to the riverbank.

They beat their horses and ran quickly, and when they reached the river, the war horses neighed and kept circling, stirring up smoke and dust.

They saw that the Tang troops on the other side of the river were noisily preparing to cross the river.

"It's not that easy to cross the river!" Zachi immediately sent men to the city to urge the army to reach the river.

Led by the officers, one group after another of the Great Eaters reached the banks of the Euphrates River, and quickly deployed along the riverbank.

There were 50,000 troops to the river, and they guarded the river for more than 20 miles.

In order to deal with the Tang people crossing the river, the fortifications of the big cannibals were well done, sharpened wooden stakes were set up on the bank, and the tip side was facing the river to block the Tang people's attack, and then a trench was dug, and the sergeants defended in the trench and prepared rockets.

Zachi deliberately trained a large number of archers, using relatively powerful bows and arrows.

Of course, no matter how much you train, if Tang Bing and the Great Food Soldier are single P, the speed and accuracy of Tang Bing's arrows are far better than that of the Great Cannibal.

But Zachi's idea was not to shoot people, but to shoot the ferry boat that crossed the river!

With such a big target, it should still be easy to shoot!

When the panting soldiers entered the trench, some of the sergeants set fire oil cans on fire, and the sheepskin rafts of the Dons had just crossed the river.

Then the big cannibal saw a long column of Tang boats, without sails, coming slowly with smoke.

Then the muzzles of the guns on the Don ship clicked open, and a door bronze pipe was pointed at them.

"Boom!"

"Boom, boom!" Two hundred meters apart, the shells fell in the middle of the big cannibals, which immediately caused riots!

"Oh my God!"

They finally saw what kind of monsters were spitting smoke and spitting fire, and what they spit out fell to the ground, and a small pit appeared, and some cannonballs scattered, and smashed them, and immediately broke bones and feet, and flesh and blood blurred!

A horse leaped and threw its owner off, startled by the steaming cannonball that fell in front of it, rather than being hit directly!

Coming from such a long distance, they could kill and injure them, but they couldn't hit them, and suddenly the army panicked, especially some of the guys who had turned to the army, they shouted and screamed, crying for their fathers and mothers, and they rushed to escape to the city.

Ginger is still old and spicy!

Zachi was also a little panicked at first, after all, you can't hit him, it's okay for him to hit you, anyone will be unhappy and uncomfortable.

But he carefully looked at the effect of the shelling and soon found out that the artillery of the Don Army was seriously insufficient!

It seems that the momentum is not small, but unfortunately, if you land on the vast riverbank, the chance of hitting a person is simply the same as the chance of being hit by bird droppings in the sky!

A boat with twenty or thirty guns, shelling the coast, is a hard hit, can not explode (flowering shells are still few, and it is far from the time of maturity), the chance of hitting is very rare!

There are not many people who are directly hit, in fact, they are all scared of themselves, trample on each other, and far more people hurt themselves than they were hit by shells.

"Hmph, that's it!"

So he ordered: "Don't panic, the iron ball of the Tang people can't hit everyone's heads, and those who dare to retreat will be killed!" ”

Let his own soldiers drive horses to give orders, and at the same time act as a military court, whoever escapes will be killed, but before killing, use a horse whip to pull back the deserters.

Under their loud scolding, whipping, and raising knives to intimidate, the big cannibals stopped their retreat and returned honestly.

quickly adapted to the artillery bombardment of the Tang Army, those iron balls were far away, but when they landed on the shore, it was really not good!

The big cannibal gradually relaxed, and in some places where the gunboats did not aim, the big cannibal actually sat down and watched the Tang people fire their cannons as if watching fireworks!

Discarding timidity, it was not a big deal to think that the cannonballs of the Tang people were not remarkable, because the naked eye could see the projectiles in mid-air, and it took a while for them to fall to the ground.

The big cannibals were pointing and pointing, which was completely different from the head rats just now, and some of the brave guys even ran horses in the shelling area, and the shells fell around them suddenly, but they couldn't hit them, but they were laughed at loudly.

……

"It seems that the artillery attack on the river bank did not work well!" On the command platform of the artillery flagship, the officers shook their heads.

They mobilized 30 gunboats, thinking that they would cover the troops crossing the river and open the way for them with artillery fire, but they were disappointed, and this task of opening the road should be difficult to complete, so that their desire to make meritorious contributions cooled down.

After the initial panic, the big cannibals were unmoved, and they even watched the Tang people firing cannons as if they were watching a play.

But Admiral Liu Qifeng said lightly: "In this case, the prince has already analyzed it in "Artillery Technique", this is an attack on the opposite side of the point, and the effect will not be very great, I don't expect us to achieve much success, and the prince has already made arrangements!" ”

In the book "Gunnery", compiled by a group of people organized by Wei Xi, the experimental data obtained by others with great painstaking work, he drew a summary from this, and described the use of artillery, such as shipping is an excellent mode of transportation, and the cannon is bulky, but the ship can easily transport it away.

The wheels of land artillery should be made large, easy to maneuver, and towed by animal power and manpower.

When used, there are artillery points to point and point to point, and the hit rate is not high.

For sieges, the cost is currently higher than that of catapults, but it should be able to replace catapults in the future.

At present, the best use is gunboats against enemy ships, pouring artillery fire at close range, and gaining a lot.

The dry goods he gave were beyond the imagination of others, because they were beyond the scope of their understanding: the laws of parabola, the principles of ballistics, the theory of kinetic energy --- potential energy, etc., were not discovered until many years later, for example, the 45-degree artillery with the longest elevation range, and now many people regard it as a heavenly rule, and strive to perfect it.

……

Liu Qifeng's words made everyone smile, and they didn't feel depressed before.

Everything was expected by the prince!

Not only the gunboat cover, but also other troops, no, the original good cannibal formation was chaotic, and some of the units changed from the rear to the front, and they were in a hurry to turn back to the city of Habaniyah.
