At this time, of course, the city of Uiju is not the same as it used to be. Pen % fun % Pavilion www.biquge.info

After more than 20,000 people continued to build for more than three months, today's Yiju Fortress has become the premier fortress outside Shanhaiguan.

If the scale of the city may not be as good as Jinzhou and Ningyuan, but if it is strong and majestic, it is far better than Jinzhou and Ningyuan.

Although the newly built city wall is still in the traditional Chinese boxy shape, in addition to the urn city outside the four city gates, a new fortress fort has been built on the left and right sides of each city gate.

The construction of the eight fortresses in the city of Uiju was, of course, the Italian missionary Wei Kuangguo and the Portuguese retired military officer Gao Kaus? The handwriting of Teixeira and others.

In the early 17th century, most of Europe's fortified fortresses were fortified against the onslaught of new artillery.

The so-called fortress, to put it bluntly, is a kind of wedge-mounted fortress, which protrudes beyond the traditional city wall, but is connected with the city wall, like an irregular diamond, the sharpest corner of the diamond, facing the attacking enemy, not only minimizing the enemy's artillery or trebuchet, but also greatly increasing the depth of defense of their own defenders.

The purpose of thickening the city wall is not to resist local artillery or trebuchets, but to increase the height of the city wall and infinitely increase the difficulty of the enemy army to climb.

However, by the advent of artillery, the traditional fortification techniques had fallen behind, and the wars in Europe in the seventeenth century proved a truth, that is, the higher the walls, the easier it was to be destroyed by enemy artillery, and to hold the city under artillery bombardment, it was necessary to build a new system of fortifications, and the new fortification system must be able to resist artillery bombardment and prevent enemy infantry from approaching.

From the 16th century, the Europeans began to study, and by the 17th century, they had finally built fortresses.

Moreover, after more than a century of practical exploration, the most suitable bastion is designed with four sides, and the two sides are combined to form a wedge-shaped protrusion outward, so that the enemy's artillery or trebuchet cannot hit the front, and you can also assume your own cannon.

The other two sides are connected vertically with the city wall, connecting the protruding wedges, and behind the pheasant wall battlements on these two sides, the defenders can use artillery and firearms to completely cover the open space between the moat and the fortress, forming a death zone with no dead ends, preventing the enemy from approaching the city behind the fortress.

The city of Yiju, which has now entered the field of vision of Chen Renxi and his party, is such a fortified city with eight fortresses, which looks strange and looks like a hedgehog curled up in a ball, but in fact it is extremely strong.

The newly built walls and all the bastions were made of concrete and stone, and behind the solid cement stone walls, all of them were made of freshly dug earth and gravel.

Such eight fortresses are not only artillery positions protruding hundreds of paces from the outward protrusion of Uiju City, but also impregnable fortifications that are not afraid of artillery bombardment.

Although the current Jin State and the Mongolian armies are not equipped with artillery, the favorite thing of Emperor Chongzhen today is to take precautions.

Because, in history, Yizhou City was occupied after it was collapsed by Jianyu with artillery, including the fall of Songshan City in the fifteenth year of Chongzhen, all because Jianyu used heavy artillery that was more advanced than the Ming army at that time.

And this is also the reason why the current Chongzhen Emperor constantly urges Lu Shanji, the governor of Jiliao, to step up the construction of fortresses in Jinzhou, Ningyuan, Tashan and Juehua Island.

Since the strategy of attacking in the east and defending in the west has been adopted, the key road of the Liaoxi Corridor must be foolproof.

After Chen Renxi, Zuo Guangxian and others arrived in Yizhou City, they met with Lin Maochun, the current commander of the left road of Liaozhen, informed each other of the situation, and specially met with Gao Kaus, who was still in Yizhou City to help the defenders install and debug the Shenwei Invincible General Cannon, and then accompanied by Lin Maochun and Gao Kaus, they went to the north gate together, and carefully looked at the newly built city and the two fortresses on both sides of the west gate that echoed each other from afar, and admired in my heart.

Lin Maochun did not participate much in the construction of the fortress, but the new fortress in Yizhou City, but this veteran from Dongjiang Town was eye-opening, and at the same time he was very satisfied with the city defense of Yizhou City, he also wrote a letter to Mao Wenlong, sent someone to send it back to Dongjiang Town, told Mao Wenlong the value of the fortress, and suggested that Dongjiang Town follow the example of Liaodong Town and build additional fortresses in important places such as Tieshan and Phi Dao, etc.

Chen Renxi looked at the fort forts that had been equipped with cannons on the left and right sides of the West Gate, of course, he was very satisfied, and after returning to the station of the Ximen Wengcheng Supervision Army Standard Battalion, Chen Renxi said to Lin Maochun: "General Lin is now the commander of the left road of my Liao Town, and he has 15,000 people under his command.

"Now that Horqin has united with the Eastern Mongolian tribes to attack Karaqin, Kundulun Khan Burhatu sent people to ask for help from me. There is no reason why the Left Route Army of Liaozhen cannot be saved.

"At present, my standard battalion of the prison army only has 2,000 cavalry, I'm afraid it is not enough. Please ask the general to allocate 5,000 soldiers and horses, and send another tiger general to lead me to the west and out of the border to intercept the allied forces of the Eastern Mongolian tribes. ”

Lin Maochun, who is nearly fifty years old, is now considered a late bloomer, from a deputy general who commands more than 3,000 troops in Dongjiang Town, to the deputy general of Liaozhen, and he is also the deputy general in charge of 15,000 soldiers along the way, which is something he never dared to dream of before.

Therefore, since taking office, Lin Maochun has redoubled his conscientiousness, lest he make a mistake and be found faulty, which not only disappoints the emperor's holy grace, but also ruins the good future of himself and his brothers.

At this time, after listening to the words of Chen Renxi, the imperial history of the Liaodong Town Supervisor, Lin Maochun immediately said: "Don't worry, Lord Supervisor! The 15,000 soldiers and horses on the left side of my Liao Town have all been adjusted. The construction of the Uiju Castle is now about to be completed. Of course, there is no problem in allocating 5,000 men and horses to follow the adults to the west. ”

After saying this, Lin Maochun looked back at the generals who followed him to the left and right, and then turned his head and said to Chen Renxi: "If the Lord of the Prison Army has no objection, how about letting Lin Chaoen, the general on the left side, follow the Lord to the border together with the guerrilla Zhu Jialong?" ”

Lin Chaoen is over 30 years old, is Lin Maochun's nephew, and together with Zhu Jialong, who is 27 or 8 years old, he is Lin Maochun's henchman brought from Dongjiang Town, and now he is jointly controlling the only more than 5,000 cavalry on the left side of Liaozhen.

When Chen Renxi heard this, of course he was overjoyed and immediately agreed. And Lin Chaoen and Zhu Jialong also immediately took a few steps forward from behind Lin Maochun to meet Chen Renxi.

After the two discussed the matter of sending troops to the border and aiding Karaqin, Chen Renxi discussed the city defense of Yizhou with Lin Maochun, and reminded Lin Maochun to guard against Jianyu bypassing Guangning and Jinzhou, and coming to Yizhou to support the allied forces of the Eastern Mongolian tribes.

Lin Maochun listened to Chen Renxi's reminder, and said with a smile: "Lord Prison Army, don't worry, go to the rescue of Karaqin!" Today's Yiju city defense is impregnable, if the captives do not come to attack the city, if the army is raised to attack, it will definitely let it have no return! ”
