The king of Goguryeo refused to surrender, and only real swords and guns were done.

At present, the balance of forces between the enemy and us is as follows: the Liaodong army has a total of 100,000 soldiers, and the Goguryeo Maru capital has 60,000 soldiers. Of these, 40,000 cavalry were brought back by the great prince, and the remaining 20,000 were infantry.

As for the coalition of the eastern tribes led by the second prince, they were already frightened birds, and they all ran back to their own tribes. Soon it will usher in the ravage and trampling of the 30,000 iron horsemen of the Buyeo Kingdom.

The Goguryeo king Bogu looked at the repeating crossbow and the Xiangyang iron sword presented by the eldest prince Baqi and was silent for a long time. The repeater can shoot 10 crossbow arrows in an instant, and can shoot through iron armor within 30 meters; Xiangyang iron knife sharpens iron like clay. And these turned out to be the standard configuration of Liaodong Iron Cavalry, one for everyone!

Bogu was deeply shocked, mud horse, how can this battle be fought?

There is no need to think about going out of the city to fight in the field, it is said that the Liaodong army also has a bed crossbow that can shoot through more than 10 people. The only hope lies in the highly sturdy walls of Maruto Castle. There was enough food stored in the city, and the army and residents had no problem feeding for a year.

Perhaps the Liaodong Army could not be attacked for a long time and suffered heavy losses; Perhaps the Liaodong Army was short of food; Or maybe there is a foreign enemy attacking Liaodong. In short, as long as you hold Maruto Castle, everything is possible!

Gongsun Kang took the strategists and generals around the city and looked at the terrain. The tactics of encircling three and missing one were formulated.

Siege the west, south, and north walls to attack, leaving the east unattacked, so that the Goguryeo people were lucky and would not defend the city to the death. The east side is for them to run. Chasing and killing in the back is much more refreshing than attacking hard.

Gongsun Kang learned about the tactics of various armies, and even admired the practices of Wuheng's cavalry. So he had the army on all three sides drive away the recently captured Goguryeo people, carrying bags of dirt and straw on their backs to fill the moat.

There are two things that Bogu is proud of: the moat is five meters wide and three meters deep, and it surrounds the entire Maruto Castle and must be crossed from the bridge. Pull up the suspension bridge, and no one can get through.

The second point is that the walls are all made of stone. At that time, it took several generations for each Goguryeo king to increase the height and reinforcement. Now the city is six meters high and four meters thick! The arrow tower and the urn city are complete, worthy of being the capital and the royal city!

Now Gongsun Kang drove the people of Goguryeo to fill the river, but Bogu was not the kind of compassionate heart of Chen Deng, because he was his own people, he did not shoot arrows, and let the people fill the moat.

Bogu ordered: Whoever approaches the moat will shoot arrows! For a time, arrows rained down, and the people of Goguryeo were shot down one after another. Those who escaped with their lives will not be driven away by any means, and will not go back to fill the river.

Gongsun Kang smiled slightly: This trick is easy to crack!

He ordered to start digging a trench outside the range of the arrows, and put planks on top of the trench to prevent it from being shot. Then the moat extends in the direction of the moat, an extension of the zigzag. When they reached the vicinity of the moat, they dug a hole and protected it with a large iron shield. Let the people of Goguryeo take turns carrying bags of soil and straw to fill the river.

Because of this measure, the arrows shot from the city walls were no longer lethal to the people.

It took 20,000 people two days to fill in the moats on three sides with a width of more than 200 meters, which was enough for the Liaodong Army to launch a formation attack.

But Gongsun Kang did not let the soldiers carry the ladder and climb the city wall like ants. He was relatively well prepared this time, and there were dozens of wells alone.

The shaft is built to a height of 3 and a half floors, and a pulley is installed at the bottom, which can be moved and strafed from a high position. All sides were covered with cowhides, and they were not afraid of the shooting of Goguryeo arrows.

During the time when the Liaodong army filled the moat, the Goguryeo army was not idle. The eldest prince Baqi led the people to dig traps near the three city walls, and then spread the thistles on the ground. Baqi really deserves to be a Chinese expert, and the Han culture he admires is actually a war culture.

You must know that in the Qingxu defensive battle, the Liaodong army did not dig a trap or sprinkle thistle.

Gongsun Kang questioned the generals and found that they barely used explosives and fire oil. Because the outer counties are all earthen city walls, bed crossbows and stone throwers alone can smash the city walls.

Looking at the other side of the moat, the ground is full of thistles and traps. Gongsun Kang smiled again. His laughter is not Cao Cao's laughter, Cao Cao's more famous thing is that as long as he laughs, there will be ambushes to kill! Gongsun Kang's smile shows that he is confident and has a way to crack it.

Tribulus terrestris and trap can be cracked with a wooden plank, right?

Gongsun Kang sent people to prepare thick planks, and during the preparation, he mobilized hundreds of catapults and began to bombard the city of Maruto.

First, several waves of head-sized rocks smashed the Goguryeo defenders to shrink their heads and hide behind concealment.

The second batch was the oil canisters in clay pots and the oil cans in wooden barrels. When both were thrown into the city, they fell to the ground and shattered, and the oil flowed everywhere.

Because the fire oil is a new thing, the defenders of the city do not know how to use sand to cover it, so they can only watch the fire oil flow.

Since the invention of explosives in Liaodong, they have been used to open mines, and they have never been used on the battlefield. Gongsun Kang decided to try it out this time. Explosives have been developed to the third generation in Liaodong. At the moment, only the first generation of the product will be used: black powder.

The third batch was thrown in explosives. The black powder was wrapped in a fragile iron sheet, ignited and thrown into the castle by catapult. One by one, the explosive packets exploded, like an earthen mine, an earthen grenade. Accompanied by the light of fire, accompanied by the sound of coaxing explosions, shattered iron sheets, flying in all directions. The high-speed impact force shot through the bodies of the surrounding Goguryeo soldiers and ordinary people. Screams of pain rang out everywhere.

The fire also ignited, and with a bang, the oil flowing on the ground began to burn. The wooden houses and furniture in Maruto Castle also began to catch fire, and the flames rose to the sky. The interior of Maruto Castle became a city of fire.

At first, the Liaodong soldiers heard the explosion of the explosive pack, and they cheered, celebrating that the Liaodong Army had another weapon of mass destruction to attack the city.

And now when they saw that Marudu Castle had become a city of fire, they were all silent. That's hundreds of thousands of lives, struggling in the fire.

Gongsun Kang looked at the fire and waved his hand to stop the throwing of fire oil and explosives packets.

The gates were opened, and the Goguryeo soldiers and civilians rushed out of the city and across the drawbridge.

The soldiers of Liaodong began to do things, shouting one after another: "Put down your arms, surrender and don't kill!" Then he aimed his crossbow bolts at the Goguryeo soldiers who had fled the city.

After the Goguryeo soldiers ran across the drawbridge, they threw down their weapons one after another, squatted on the ground, and waited for the attack.

The Liaodong soldiers were very experienced in accepting and surrendering, and they stepped forward with a clear division of labor, evacuated the crowd, and guided them to line up and walk to the Liaodong military camp in the rear.
