Liaodong was surrounded by tens of thousands of soldiers and civilians, always can not sit idly by, rescue is urgent, the holy decree was issued, Shanhaiguan, Denglai, Jizhen sent troops to aid Liao, for a time the wind in the customs and the price soared. Pen & Fun & Pavilion www.biquge.info

The honest man Sun Yuanhua urgently ordered the general Kong Youde to lead 1,500 cavalry to Liaodong for reinforcements, and Zhang Chun rushed to Shanhaiguan with 10,000 cavalry and 3,000 chariot battalions in Yongping.

Yongping's general Black Tiger had 5,000 troops, and of course he was in the ranks of the troops, so he had to personally lead 3,000 men and horses out of the pass.

Ma Xianglin and Qin Yiming wanted to bring 7,000 white pole soldiers to participate in the battle, but Emperor Chongzhen rejected them, and the emperor knew the combat effectiveness of the white pole soldiers and recognized their loyalty and bravery, so they were left to guard the Shanhaiguan in case of accidents.

In the battle of Daling River, in fact, Sun Chengzong could not shirk the blame, he did nothing as the main general of the Ming army against the Red Gangsters, and actually sent reinforcements one by one, which really became a tactic of adding fuel.

In the history of the Battle of Dalinghe, the iron facts proved that Sun Chengzong's tower attack strategy was not advisable, and the construction of Dalinghe City was even more stupid, it seems that the fortress can occupy some places, but what is the effect?

No matter how big a city is, the occupied territory is only a little bigger, and the hard-working tuntian of the Ming army cannot be harvested at all, and it produces grain for Houjin in vain.

The Ming army could not get grain on the spot, and the supplies had to be transported from the Guannai for thousands of miles, which consumed a lot of the Ming Dynasty's already unsustainable national strength.

The battle line was too long, and the Houjin army could attack the Ming army's supply line from Shanhaiguan to Jinzhou for 500 miles at any time.

Fortified camps and fortresses were built to bring about the area, not just to occupy a small part of the city.

Instead, they should rely on a strong fortress to attack the enemy army within a radius of 100 miles, gradually expanding the occupied area step by step, either to repair the city or to hide inside and wait for the enemy to attack.

Huang Sheng is arranging and building nine border towns in Jiaozhi, preparing to garrison a total of 1,200 soldiers and 800 auxiliary soldiers in the forts of each border town.

The task of garrisoning Qianzong is to use the fortress as a base to continuously extend and attack the enemy country for a hundred miles, and if the opponent has strong troops, he can join forces with several border towns and townsmen to attack.

The army that constantly takes the initiative to attack will become stronger and stronger, and the Ming border army, which is always shrinking to defend, is naturally difficult to drum, so the strategy of taking the fortress encroachment in Liaodong is not worth the loss, it is too waste of silver, and the imperial court is embarrassed.

The Red Gangsters besieged Jinzhou and Dalinghe, and the general's artillery brought by the rear army also arrived at the Dalinghe battlefield, and the shelling began.

Zu Dashou also had artillery to defend the city, and the power and range of the two artillery pieces were about the same, with an effective range of three or four hundred steps, that is, more than a mile.

The maximum elevation angle can send a shell out of a thousand steps, that is, 1,500 meters, which is equivalent to three miles away, but where does the shell end up? God knows!

The technology of the Ming gunners is even better, the rate of fire can be achieved after the Jin army gunners shoot three cannons, and the artillery fire at the head of the Daling River city can come in four rounds, and the Ming army is condescending, so it should not suffer.

The Hongyi cannon is a kind of recital front-loading smoothbore gun, and every time it is fired, it will seriously deviate from the original firing position. According to the normal operating procedure, it is necessary to go through the steps of resetting, reloading, and setting the direction angle and elevation angle again.

The most well-trained British naval gunners of this era could only guarantee that they could fire again in three minutes, which was one minute worse than the level of the Huang gunners.

Because the steel cannon with shock absorption device produced by the Huang family can subtract the time of gun reset, relying on the power of science and technology to save a precious minute.

In this era, it was not possible to increase the rate of fire of front-loading artillery, because after firing once, a special push rod had to be dipped in water into the gun chamber, extinguishing the fire star, and a push rod tied with a dry cloth was stretched into the gun chamber to dry, and then filled with gunpowder, propellant, stuffed into the shell, and then pierced the gunpowder bag through the fire door and inserted the fuse and then lit it.

These movements were rather slow and cumbersome, not counting the correction of gun emplacements. This is a common problem of front-loading artillery, can be three minutes a shot is the top master, the Ming army gunners can do half an hour 16 shots, the Houjin army gunners only half an hour 12 times.

And then? No then. The cast iron cannon of this era did not dissipate heat ideally, and it was only possible to shoot more than a dozen shots in a row. At this time, the temperature of the gun chamber is overheated due to continuous firing, and continuing to fire will lead to accidents, and maybe the gunpowder pack will explode directly if it is advanced.

Because the artillery equipped by the Later Jin Army and the Ming Army could not achieve the unified standard of the Huangjia artillery, each artillery had a personality, and the gunner could only be familiar with the artillery he often controlled, so that he would have a certain accuracy, and he could not casually transfer a group of gunners to complete the shooting of unfamiliar artillery.

The fight can be started, and there are too many uncertainties.

The command ability of the eight small schools can be called first-class, and he decided to make up for the shortcomings of quality with quantity according to the situation, and he took a concentrated attack and chose the gentle terrain to bombard the south gate.

On both sides of the offensive and defensive sides, there are no steel field guns produced by the Huang family, they are all cast iron artillery, all of them are extremely bulky guys, the recoil is terrifying, and there is no shock absorption device at all.

Although the artillery of the Houjin Army was not condescending and lost its geographical advantage, it was fortunate that it could move its position and choose the most suitable place to place it and fire.

There is no recoilforce when firing on the ground, but after firing a shot, you must go and put the guns that have jumped out of place back into place and aim them again.

The Hongyi artillery deployed by the Ming army could not do this, and their artillery must have a specially built strong battery to fire, not just casually swing on the city wall.

The Hongyi cannon is a front-loading heavy smoothbore gun widely used in Europe on warships between the 16th and 19th centuries.

The Ming Dynasty called all front-loading smoothbore cannons imported from the West as Hongyi cannons, and after being imitated by the Ming Dynasty, there were as many as 100 kinds, and the quality and use had come out of the blue.

However, the Hongyi cannon, which can fire twelve-pound shells, has already reached four or five thousand catties in weight, and its recoil is amazing.

The city wall looks majestic, but the firmness is actually not worth mentioning, it is equivalent to a wall of rammed earth eight or nine meters high and four or five meters wide with a layer of bricks on the outside, and the recoil of the cannon will cause the city wall to collapse.

The concentrated use of firepower by the Later Jin Army was very effective, and the artillery at the head of the Ming army suffered a local contrarian loss, because the six Hongyi cannons of the Ming Army had already been loaded and ready to go, and the Later Jin Army was attacked by the Ming artillery when arranging the general's cannon.

Fortunately, most of the accuracy of artillery in this era relied on luck, and the Ming army played three rounds of eighteen large iron balls in the early tens, but only two of them smashed the general cannon of the Houjin army.

There is no doubt that the two artillery pieces of the Houjin Army were scrapped and withdrawn from the battle sequence, but even so, the artillery of the Houjin Army was still four or five times the number of artillery in the north of Dalinghe City.

When the artillery of the Houjin army began to roar, the officers and soldiers of the Ming army defending the city felt bad.

After the Jin army threw a solid iron ball hit the good luck and landed on the city wall, a cannonball can not only jump and cause the Ming army to kill and injure, but also smash the masonry to cause splashing.

The flying stone chips and bricks were enough to break through the armor at close range, causing a large number of casualties to the Ming army.

The power of the artillery shells fired by the Ming army condescendingly was much smaller, there were wheat fields, and the red gangsters piled up a lot of mounds in order to deal with the artillery bombardment of the Ming army.

The artillery shells of the Ming army fell, smashed into the soft wheat field, and the power would be consumed if they could not jump a few times, and if they were unlucky enough to hit the mound and drill into it, it would be a waste of gunpowder and a waste of time.

The Ming army defended the city quite tenaciously, and the artillery tried their best to load and fire one by one, so you went back and forth for an hour and a half of artillery battles, and the six Hongyi cannons arranged on the north wall of the Ming army were destroyed by the Houjin army one by one.

The Red Gang was overjoyed, and in order to show off, he specially invited the Mongolian Taiji and major generals to watch the battle.
