In the first year of Yongxing or Emperor Tian, Northern Yan attacked Jinhai City, which took one hundred and eighty-nine days; In the battle, the defenders of Jinhai were killed in battle and the generals who died of serious injuries after the battle, a total of 14,000 people, and less than 13,000 generals were left to retreat south, and Beiyan also paid the price of more than 40,000 casualties for this cruel and long offensive and defensive battle.

Time flies, and eight years are like flowing water from your fingers-

On the 27th, Li Baidao's headquarters of the 1st Brigade of the Denghai Town Division landed at the north trestle bridge of Jinhai Port, close to the elite of the 3rd Brigade of the Denghai Town Division, and together they attacked the main fortress of Jinhai City, which was built on the basis of the Vortex Kou Village in the early years.

The 32-pound heavy artillery was erected on the ruins of the collapsed sentry pier at the mouth of the Whirlpool River, and every time it was fired, the ground shook.

Although the city wall of the main fortress is built with rammed earth as the core, covered with masonry as the table, and the wall base is also erected on the whole block of big bluestone, but such a solid city wall, under the bombardment of the 32-pound heavy artillery at a distance of about 800 meters, every time it is shot, it will directly open a big gap, and the branch cracks of the city wall are cracked, as if to be hit by thunder, and the masonry fragments are splashed, and the power is not under the arrow, so that the defenders of the city head suffer a lot.

The artillery cast by Huaidong, with a long barrel, has no high obstacles in the middle, and bombards the city wall three or four zhang high at a low flat firing angle, which has a very high accuracy, except for a few shots of the test cannon, and then almost seven or eight hits out of ten, and the solid iron bullet that passes through the city wall also has a huge destructive force that collapses with one blow to the building in the main base.

The destructive power of a solid iron projectile fired at a low flat angle to the city wall is much higher than that of a stone projectile thrown in a parabolic direction from a catapult.

The main fortress of Jinhai City is such a strong fortress, if it is used with heavy stone-throwing crossbows, it may require dozens of heavy crossbows to line up and continue to bombard for several days before it is possible to collapse the city wall.

Under the blow of four 32-pound heavy guns, the east gate of the main fortress of Jinhai City was shattered by a cannon, and the broken bricks and stones filled in the door hole also splashed sideways; The east city wall, after hitting more than ten times in a row, began to collapse in a large section - the defenders wanted to use the wooden fence to plug the gap, and several eight-pound light guns deployed in front of the heavy artillery fired flat at the gap in the city wall, and immediately smashed the wooden fence several zhang wide into pieces, together with more than 100 enemy troops behind the wooden fence were also torn apart, the corpses were vertical and horizontal, the blood flowed like a river, and there was a wail.

The enemy dug a large cellar in the main fortress, covered it with thick wood, and hid its pawns in it to avoid artillery shelling, and then repaired the city wall after the shelling - this was indeed an effective strategy for the defenders in the fortress to avoid casualties during the shelling, but they faced the elite soldiers of the Huaidong Army, who were both offensive and defensive, and whose offensive combat effectiveness was known in the world.

After the main fortress of Jinhai City appeared enough to use the broken ground, as soon as the artillery bombardment stopped, hundreds of soldiers who dared to die in the Denghai Town Division attacked the broken ground of the city wall, and forcibly suppressed the enemy troops who rushed to make up the defense, and then dragged several four-pound light cannons directly onto the ruins of the collapsed city wall, and directly bombarded the fortress with artillery on the ruins.

The defenders then took refuge in the cellar to avoid the shelling, and they were dealt with by the Huaidong Army's traditional fire oil tank tactics.

The first and third brigades of the Denghai Town Division, mainly composed of the old soldiers of the Yuanjin Navy, have their pride in Jinhai, and also have countless painful memories of the death of the robes......

On the 28th, the entire main base was captured, and the 1st and 3rd Brigades of the Denghai Town Division suffered 400 casualties and annihilated 3,000 enemy defenders; There were even unnecessary casualties in order to completely annihilate the enemy's pawns.

The commanders in charge of the Jinhai outpost war, Ge Cunxin, Zhang Gou, Chen Yan and other generals, clearly demanded before the war that the siege generals forbade the killing of Hu women and children - a large number of defenders left in Jinhai City did not withdraw in advance, and the war developed so rapidly, and there was not enough time for the defenders to withdraw their women and children - although there was a ban, but after the evil example of the assassination of the Hu people's wives and children by the generals appeared, the ban was no longer strictly followed, as long as the Hu Lu women and children with swords and weapons were found on their bodies, regardless of 3721, everything was killed on the spot.

At this time, the 5th Brigade of the Denghai Town Division, the 1st, 2nd, and 4th Brigades of the Zhang Gou Division of the 1st Town Division of the Fengli Division, and the 1st Brigade of the 3rd Town Division of the Haidong Xingying Army He Zongliang had also completed the landing, and the front quickly extended to the middle and north bases of Jinhai.

The southern fortress, which was also located at the mouth of the Whirlpool River, was directly bombarded by the task force's gunfire into ruins, and when the 2,000 defenders landed at the 3rd Brigade of the Haidong Camp Army, only 6 or 700 people were left to flee west to Wang Dengtai Mountain.

The middle base and the north base of Jinhai City are within the range of the naval division's gun. The dense artillery coverage and heavy artillery bombardment of the city, combined with the strong assault tactics of the elite infantry brigades, enabled the enemy defenders to come up with countermeasures, and the middle and north bases fell on the 29th.

Obviously, the defenders also realized that the number and firepower of the Huaidong Army's naval division's gunwales were far higher than those carried by the infantry brigade.

Of the three brigades that had landed in Denghaizhen, only the 1st and 3rd brigades had crossbow battalions, and they were mainly composed of highly mobile light artillery, and the destructive power of light artillery on the strong city wall was far less considerable than that of heavy artillery.

The western base is five miles away from the coastline, and the coast controlled by the Huaidong Army in Jinhai has no high ground that can erect heavy artillery and increase the firing range. Between the west base and the coast, there is a broken wall between the main base and the middle base, which blocks the firing angle of the artillery to a considerable extent. In addition, the middle base, the north base, and the west base were too close to each other, and there were only three to five hundred paces between them, so it was not suitable to directly erect artillery, and it was easy for the defenders to counterattack and break through -- the enemy obviously saw these characteristics, and from the 29th, they focused on strengthening the defense of the west base.

By the 29th, 30,000 cavalry reinforcements and 10,000 cavalry from Jinan directly strengthened the defense of Yanjing, and 20,000 cavalry rushed to the periphery of Jinhai City with Ye Ji Duodi.

The cavalry was not good at defending the city, and the 20,000 cavalry were mainly deployed in the area west and north of Wangdengtai Mountain, which was far away from the coast, and wanted to suppress the Huaidong Army from the north and south flanks of Jinhai City to land and encircle Jinhai City with the edge of cavalry.

Ye Ji Duodi did not expect to defeat the Huaidong Army on the battlefield, which was so strong against the sky at this time, that he only hoped to delay the war as much as possible. Even if the capital is abandoned at this time, it is not something that can be done in a day or two to move the wives and children of more than 100,000 tribes in Yanjing City with the army-when he saw that the west base could be defended, Ye Ji Duodi even selected 3,000 dead soldiers from the cavalry who came to strengthen the defense of the west base.

What Ye Jiduodi didn't expect was that nearly 1,000 people in the industrial battalion of the Huaidong Army were craftsmen directly drawn from major mining areas.

In the past few years, Huaidong has made the southern iron output exceed 140 million catties, the coal output exceeded 60 million baskets, and the iron ore mining volume exceeded 8 million baskets.

Before the war, the military headquarters carefully considered attacking cities and plundering land in the north, especially in mountain cities and cottages that were difficult to transport by heavy artillery, and digging tunnels to fill in gunpowder and directly blast open the city walls was a quite feasible tactic.

This tactic was first used in the west base of Jinhai City.

Eight hundred miners excavated from the underground of the middle base, and it took only three days to dig the tunnel to the east wall of the west base.

Thousands of catties of gunpowder, which is more powerful than the black powder in his memory, are buried directly at the top of the pit and twisted with medicine.

The traditional tunnel tactic is to dig directly through the city wall and send surprise soldiers to attack the heart of the enemy fortress - even if the tactic of digging a big hole under the city wall and then pulling out supports to make the city wall collapse, it is also necessary to dig the hole under the city wall large enough and deep enough, which is obviously not a tactic that can be implemented in a short time.

At the moment when the gunpowder was ignited, they saw that the eastern wall of Jinhai Xili was thrown into the air like a jet in an instant in the explosion of the sky and the earth.

The bricks and mud fell one after another as if it were raining; The explosion was so fierce that the 3rd Brigade of the Denghai Town Division, which led the bombing of the city, was also caught off guard, resulting in four generals on the battle formation being smashed by bricks and stones and needlessly killed.

Chen Zhen, who rushed to the front of the battle to watch the battle, was also prepared to smash his left arm with a small half of the city brick, and became the highest-ranking general of the Huaidong Army on the battlefield at this time in the Northern Expedition-

The enemy defenders mainly gathered under the east city wall before the explosion, and the number of people gathered at the explosion point was extremely dense, and those enemy guards who were thrown into the air were killed or fainted or wounded in the air, and as the masonry and mud fell one after another, there were the following dumplings - after the battle, it was impossible to count how many enemy soldiers were killed directly, or fell to death, or buried alive the ruins of the city wall that fell back to the ground during the bombing of the city.

The enemy defenders, who were barely accustomed to heavy artillery bombardment, were demoralized by such a powerful explosion from the ground, and fled - the guards wanted to flee for their lives, but they did not give them a way out of the ascension to heaven in the western base. When the generals of the Huaidong Army attacked from the gap, they were just like helpless mice, fleeing with their heads in disorder, wanting to surrender, but the attacking Huaidong Army had no intention of killing them when the siege of the fortress had just begun.

Ye Jiduodi gathered nearly 10,000 defenders in Xilei, except for a few guards who escaped, and finally the Huaidong army counted less than 2,000 prisoners of war in Xilei. In the Battle of Xili, the 3rd Brigade and 5th Brigade of the Denghai Town Division and the 2nd Brigade of the 1st Town Division of the Fengli Army killed more than 7,800 guards, but the excessive killing of the enemy without leaving prisoners also made the casualties of the Huaidong Army in this battle reach 800.

In addition to the 2nd and 4th brigades of the Denghai Town Division, the Chu Zheng Division of the 3rd Town Division of the Fengli Army, which boarded the ship from Haizhou, rushed directly to Jinhai to land without stopping, and by 4 May, the infantry brigades that landed in Jinhai included the 1st and 3rd Town Divisions of the Fengli Army, the Dengzhou Town Division and the Haidong Xingying Army, two super-organized brigades, with 55,000 casualties.

In addition to the 35,000 men of the 1st and 2nd Task Forces, including the 1st and 2nd Task Forces, and the 1st Town Division of Jinghai, the Workers' Battalion also had five brigades of nearly 15,000 workers and soldiers to complete the landing in Jinhai.

At this time, to the west of Wang Dengtai, Ye Ji Duodi only had 20,000 remnants in his hands, and the total strength of the Yan enemy guarding Yanjing was only 50,000.

Although the remnants of Ye Ji Duodi's command to the west of Wangdengtai Mountain were mainly cavalry elites, how could they not waver in their military spirit when they saw such a sharp siege force of the Huaidong Army, and saw that the nearly 20,000 Jinhai defenders were wiped out in the city fortress with almost no chance of struggling?

Even if it is a bloody warrior who has experienced a hundred battles, he will be afraid at this moment, and there will be a panic that the Huaidong Army cannot shake, not to mention that the elite number of infantry brigades of the Huaidong Army landing into Jinhai has far exceeded them!

On May 5, Lin Jian and the people of the commander's headquarters landed on the land of Jinhai, looking at the scorched earth of Jinhai that was in ruins, Lin Lian, Gao Zongting, Song Fu and others sighed: "Ten years is just a snap of your fingers! ”

Gao Zongting thought to himself: At this time, it is less than ten years since Lin Lian Chongguan sneaked to Jinhai in the winter of the eleventh year to determine the salt and silver grain protection, who would have thought that the changes in the mountains and rivers in ten years would be so earth-shaking?

Seeing that the Goryeo prisoner Choi Hyuk was also in the crowd, Lin Jian summoned him to him and asked, "How would you and your father hope the Goryeo war will end?" ”

was captured from Hejin Island, escorted to Haizhou, and accompanied Luo Wenhu as a prisoner, and watched the Battle of Dengzhou and the Battle of Seizing the Island and the current Jinhai Landing Battle with the army - Cui He only saw the elite Yanhu who was once regarded as an invincible enemy in the world by the Goryeo people, like a baby, to the Huaidong Army, which was defeated and annihilated; In the face of such a rebellious Huaidong army, don't talk about his Cui father and son, what choice can the whole Goryeo people have?
