"The Goryeo Army is forcing us to fight a decisive battle with them!" Yu Ming was in the city guard mansion, holding the latest battle report, and after learning the current situation in Liaodong City, he sighed and said. The generals of the Broken Rear Army have all come to the mansion to discuss the current situation together.

"General Yu, can't we spend any more time with them?" Lin Mo asked.

In the past few days, the Goryeo army has also launched several attacks on Liaodong City, but they have all been easily repelled by the Sui army. As the defender of the city, the losses of the Sui were of course much smaller than those of the Goryeo army, and the proportion of battle losses was about one ratio, and if it continued like this, it was estimated that the Goryeo army would be forced to retreat because it could not afford such huge casualties.

"The problem now is not a military problem, but a political problem." Yu Ming explained: "The Goryeo army has already divided its troops to other towns around Liaodong City to loot. Although they will make those Han surnames who have moved to Liaodong hate them, and make it difficult for them to control this area in the future, in a short period of time, they can alleviate their food shortage and at the same time cause us a lot of food pressure. ”

"Moreover, after the Goryeo army tastes the sweetness, they may further increase the scope of looting, and even divide their forces to attack our towns in western Liaoxi. If they were allowed to capture the city adjacent to Zhuo County, it would be tantamount to cutting off our army from the rear. At that time, I am afraid that the party that can't hold on first will be us. Eldest Sun Wuji added at this time.

"So that means now we have to fight the Goryeo Army head-on?" Wei Chi Jingde pondered for a while and asked.

"That's right." Yu Ming said helplessly. His original idea of relying on the fortress of Liaodong to drag the Goryeo army to retreat seems to have failed.

"Boss, are you confident that you can defeat the Goryeo Army?" Guo Yi asked with a big grin.

"There is still some confidence, after all, we also have our advantages." Yu Ming said after thinking for a while.

"That's it! Boss, you go ahead and do it! We believe in you! Lin Mo said without hesitation.

"Okay, I'll give it a try...... By the way, Mo, did you dig a tunnel leading to the outside of the city as I requested? After Yu Ming nodded in agreement, he suddenly asked.

"It's a dug one, but where to go outside the city, I have to ask the person in charge of digging the tunnel." Lin Mo hurriedly nodded in agreement.

"Well, if this tunnel leads to the outside of the city, I am sixty percent confident that I will be caught off guard by killing the Goryeo army." After Yu Ming heard this, he slapped the table and said, "My plan is like this......"

……

In the next few days, the Sui army greatly strengthened the counterattack, and several times while the Goryeo army was still building a ladder, they went out of the city with cavalry, wantonly killing and wounding the siege infantry of the Goryeo army, causing heavy casualties to the enemy's attackers. When the cavalry of the Goryeo army rushed up to support, the cavalry of the Sui army withdrew to the city, and the Goryeo army was returned with a burst of arrows and rolling stones.

After a few days like this, Gao Jianwu finally couldn't bear it anymore and summoned back several generals who had been sent out to loot and prepared for a large-scale attack.

When the Goryeo army gathered forces to launch a new offensive again, the Sui army closed its doors and put on a posture of shrinking in a turtle shell to defend the city with all its might, but the Goryeo army failed to achieve results, so it was willing to stop the army, so the soldiers pressed in and surrounded Liaodong City for a fierce attack.

The Goryeo army stormed the city for a whole day, and did not begin to retreat until sunset, when the men and horses were sleepy. At this time, Yu Ming commanded the Sui army to pour out of the nest and set up a decisive battle outside the city.

Although the Goryeo army was relatively tired, Gao Jianwu obviously did not want to miss this rare opportunity to fight the Sui army in the field. So the whole army also pressed on, and the Sui army began a head-on duel outside the city.

The formation that Yu Ming put on this time is a crab formation, and the main force is on the two wings.

He placed 2,000 heavy cavalry on the left and right flanks, and behind the cavalry were light infantry, mainly archers, sword and shield soldiers, each numbering 10,000 soldiers, and these soldiers were basically veterans of battle. They were led by Luo Cheng and Wei Chi Jingde.

Yuming's Chinese army was dominated by new recruits and wounded veterans, led by himself, and their number was only more than 20,000, but all of them were hoplites. Although their combat effectiveness is poor, they have the city wall behind them, and they are supported by trebuchets, ballistas, and archers on the city wall, so even if they can't defeat the enemy, they will not be defeated badly.

Moreover, the Goryeo army could not outflank the left and right flanks of the Sui army from the rear because of the city wall behind them, as the two armies did in a field battle.

Therefore, Yuming does not have high requirements for them, he only asks not to be defeated by the enemy and collapse the whole army.

As soon as the two sides first fought, Yuming's Chinese army, as expected, began to be a little overwhelmed. Gao Jianwu was overjoyed when he saw this, and ordered Gaisu to immediately carry out a surprise attack.

In this way, the Sui army was sure that it could not support it immediately, and began to retreat one after another.

Gaisu led the Goryeo army to press, defeated the Sui army's central army, and slaughtered directly to the root of the wall from the city wall of Liaodong City.

At this time, the long-range attack equipment such as trebuchets and ballistas on the city wall, under the command of Lin Mo, began to exert their power, and they carried out a fierce bombardment of the Chinese army that was pressing forward.

Although the Chinese army in Goryeo was all elite troops, they were flesh and blood after all, and they could not withstand the attacks of these boulders and crossbow arrows, and after resisting for a while, they found that it was impossible to block the attacks of the ballistas and trebuchets with their shields, and in the case of heavy casualties, they were forced to retreat backwards, trying to retreat beyond the range of the trebuchets and ballistae to stabilize their position.

Unexpectedly, the heavy infantry armed with spears and huge shields were naturally unstoppable as they advanced. But turning around when backing down is very inflexible. Moreover, they had to retreat on the one hand, and on the other hand, they had to deal with the shooting of the archers of the Sui army who had returned from killing, and it was even more difficult to retreat calmly, and the formation of the Goryeo army immediately began to be a little chaotic.

Seeing this, the front-line commander of the Goryeo army, Euljideok, hurriedly let his archers rush forward first to shoot at the position, covering the pikemen and shield men to retreat.

Seeing that the opportunity could not be missed, Yu Ming immediately ordered the heralds at the head of the city to raise flags and issue an order, allowing Luo Cheng and Wei Chi Jingde to lead the cavalry troops on both wings to attack.

Gao Jianwu saw that the left and right wings of the Sui army had been dispatched, so he also ordered the heavy cavalry on both wings of the Goryeo army to be dispatched, and the two sides fought to the death on both wings.

However, judging from the scene, the cavalry of Goryeo still had a slight advantage, firstly, they were more numerous than the Sui army, and secondly, the Goryeo army was stationed in Liaodong for a long time, and it was stronger than the cavalry of the Sui army in terms of cavalry and archery.

It's just that the Sui army knew that there was no way to retreat, and they fought desperately one by one, making up for the difference in combat effectiveness between the two armies to a large extent.

The fighting troops on the left flank of the two armies approached the banks of the Liao River. The strength of the two sides is almost the same, and if either side has a fresh force to invest, the victory will be tilted to which side, but with the current situation, the reserves of both sides have already been dispatched, and it is impossible to put more soldiers into the left flank.

And the Goryeo army began to gradually gain the upper hand due to its superiority in numbers and experience, and the commander of the left wing of the Goryeo army, Yuan Zuo, also had a rare smile on his face. However, just as he was about to order the whole army to assault and charge, turning the advantage into victory, he suddenly saw a large number of Sui ships appear on the river. The hulls of these vessels were huge, apparently coming in along the river.

"The counterattack starts now! The fleet was ordered to attack the enemy's left flank at once. Yu Ming ordered at this time in the Chinese army.

With the wave of the signal flag at the head of the city. The Sui ships on the course of the Liao River roared. The decks of these ships were improvised trebuchets that threw boulders at the Goryeo cavalry on the shore, and rows of longbowmen appeared on the side of the ships and began to shoot at the cavalry of the Goryeo army.

The Goryeo army was caught off guard, and the cavalry were smashed by the boulder and overturned, and they were not hit, while they had to dodge the arrows fired from the warships on the river, and on the other hand, they had to deal with the Sui cavalry in front of them, and the situation immediately reversed, and the Goryeo army changed from having the upper hand to being at a disadvantage, and the situation continued to deteriorate.

"Damn! How did these ships come about? When did the Sui army have so many boats in the Liao River? Yuan Zuo shouted in panic.

"Hehe, the Goryeo army would never have imagined that I would transfer the ferry boat in the Yalu River to the Liao River to participate in the attack." Yu Ming said with a smile.

"Amin, you're amazing! The battle plan you proposed to transfer the ferries from the Yalu River to the Liao River and then attack the troops on the banks of the river from the river is unheard of by us, but it is very practical and takes the enemy by surprise. "The eldest grandson Wuji is really full of praise for Yuming. Yuming's plan to let the ferry ship coordinate the attack was really an eye-opener for him.

"We were also lucky this time, it happened that the Holy Lord had built a large number of ships in order to force the Yalu River to cross the Yalu River. And another 100,000 men and a large number of siege equipment were left behind, so that we could use them ready-made. Otherwise, it will never work. Yu Ming said.

In order to be able to drive the boat originally placed in the Yalu River into the Liao River, and then carry some simple trebuchets on the boat, he still had a lot of brains. If it weren't for the fact that there were as many as 100,000 people, I am afraid it would have been very difficult.

The battle on the left flank was now decided, and the Goryeo cavalry, although brave and good at fighting, was also flesh and blood. Under the attack of stone bullets and arrows on the ships of the Sui army, they gradually showed signs of defeat. Guo Yi, who commanded the cavalry on the left flank of the Sui army, naturally did not let go of this opportunity, and led his heavy cavalry to beat the water dogs, although the number was far less than the enemy, but also killed the corpses of the Goryeo cavalry all over the field and screamed again and again.

"Quickly report to Marshal Gao about our situation here, if we don't send people to support, our left flank will collapse." Yuan Zuo's face turned pale at this time, and he hurriedly gave an order to the herald.

After listening to the report of the herald sent by Yuanzuo, Gao Jianwu's face was also pale.

He sighed: "It seems that I still underestimated Yu Ming, I didn't expect him to find a way to drive the ferries of the Sui army in the Yalu River to the Liao River, and kill us by surprise!" ”
