The next day, Yu Ming, Luo Cheng, the eldest grandson Wuji, and Wei Chi Jingde inspected as usual. They climbed to a high platform by the river, and after looking at the enemy troops on the other side of the river, Yuming suddenly let out a surprised "huh".

Luo Cheng hurriedly asked, "Did General Yu find anything?" ”

"You see, the enemy seems to have a lot fewer sappers on rafts by the river, and although the number of tents has not changed, there are much fewer people around the tents." Yu Ming said.

"I feel a little wrong with that. In the past, the enemy had to send scouts to harass us every day, but for a long time, the enemy was still very quiet, and did not send scouts across the river. Wei Chi Jingde said after thinking for a while.

"Could it be that the enemy army went far upstream and then crossed the river from upstream to outflank us?" Yu Ming asked with a move in his heart.

"Probably not. We have set up observation posts on every hill, arranged for competent scouts, and if the enemy makes any moves, we will immediately release carrier pigeons to report. Moreover, the Yalu River in this area is turbulent, and most of the banks are canyons and cliffs, so the real place suitable for crossing the river is actually our place. Eldest Sun Wuji frowned slightly.

After a pause, he added: "Although there are several other places where you can cross the river, they are all small docks, which are not suitable for a large number of troops to cross the river...... In fact, there have been small groups of enemy troops crossing the river from other places before, but they were all routed when we discovered them. ”

"It's hard to say! At once, Jingde, send out your best scouts, divided into ten teams, each with a carrier pigeon, and go to the upper and lower reaches of our camp, up to fifty miles. As soon as there is an abnormality, the battalion will be notified immediately. Yuming is still very worried.

"Okay! I'll do it right away. Wei Chi Jingde immediately called his own general and asked him to go to the waiting and carrier pigeons.

"By the way, General Luo, in the battle some time ago, did you find that the enemy used long-range attack equipment, such as catapults, ballistas, etc.?" Yuming asked.

"Not yet, I guess they want to wait for a head-on battle with our army before using it in the final decisive battle." Luo Cheng replied.

"Well, now although we are better than them in terms of equipment, we have fewer people, only one-half of each other, if we really fight hard, we will still be at a disadvantage." Yu Ming smiled bitterly in his heart. I secretly wondered how to command the war by myself, and the troops were at a disadvantage in every field.

At this time, the four of them studied various strategies and methods to resist the enemy army. Because you have to defend the Yalu River for at least a few days, you can feign defeat and retreat, otherwise you will be defeated at the first touch, but you will be defeated without chaos. Anyone can be suspicious.

After returning to the camp, Wei Chi Jingde's adjutant came to report that he had found that the enemy had set up a pontoon bridge on a cliff ten miles upstream, and that about 5,000 people had crossed the river and were hiding in the dense forest on the top of a hill. It is estimated that when the Goryeo army officially launched the battle to cross the river, it will attack the rear of the Sui army.

When Wei Chi Jingde heard this, he was so frightened that a cold sweat broke out on his back, and he asked eagerly: "How did the enemy cross the river?" How could the lookout post not find out? ”

"General, the scouts we sent took a closer look at the pontoon bridges erected by the enemy. It is estimated that they should first tie the steel to the cliff on the bank of the river on their side, and then send a few agile martial arts masters to carry the steel to cross the river, and then climb the cliff with steel claws, and then go to the top of the cliff to embed the steel into the rock. Finally, a few pieces of steel were straightened and planks laid to form a pontoon bridge. Because of the sheer cliffs here, our scout camp thought it was impossible to cross the river from there, so there were no lookouts. His lieutenant explained.

The use of steel to erect pontoon bridges at both ends of the cliff is indeed clever, and I am afraid that such technology and ultra-high toughness and quality of steel are not something that the Koreans can have. Yu Ming secretly marveled in his heart. He didn't know that Hu Sizheng, the former squire of the Great Sui Army, had arrived in Goryeo and became his secret enemy.

"General Yu, then let's send an army to destroy those five thousand enemy troops! lest they become a great trouble for us! Guo Yi rubbed his hands and said.

"I don't think so. To completely wipe out their 5,000 men, it is estimated that we will have to mobilize at least 10,000 or more to ensure that we can defeat them. At this time, if the enemy army on the other side of the river attacks, our battalion will only have more than 10,000 people left, and if the enemy comes with 20,000, I am afraid that it will not be able to resist. After thinking for a while, Yu Ming immediately rejected the proposal.

"And how to deal with their division of troops?" Guo Yi was worried.

"In this case, let's go quietly to the hill where the enemy army is hiding to see the terrain first, and then make a decision." Yu Ming said.

When the generals heard that the Goryeo army had smuggled over 5,000 people, they were all frightened into a cold sweat. They all asked to check the enemy situation with Yuming.

Of course, Yuming would not agree to go with so many generals, in case they were discovered by the enemy, they would be killed. In the end, Yuming only selected the eldest grandson Wuji, Luo Cheng and Yu Chi Jingde to go together.

They reached the cliff where the scouts had reported first. I saw that the water flow here is slightly gentler, and the distance between the cliffs on both sides of the bank is very short, only less than two zhang. No wonder the Goryeo army chose this place to erect a pontoon bridge.

At this time, everyone also found that dozens of sappers of the Goryeo Army were hurrying to dismantle the temporary pontoon bridge, probably for fear of being discovered by the Sui army scouts.

Everyone was secretly glad when they saw this scene, if it wasn't for Yu Ming's heart, he would send scouts to check first, and after the Goryeo army dismantled the pontoon bridge, even if they sent people to investigate, they would not find clues.

After that, everyone went to another small hill next to that kind of high mountain, and saw that the mountains where the Goryeo army was hidden were dangerous, easy to defend and difficult to attack, and if they really wanted to send troops to attack them, I am afraid that they would never be able to take it without sending more than 15,000 troops.

Of course, it is also possible to besiege them, and when they run out of food, they will collapse naturally. However, now that the main force of the Goryeo army is imminent to cross the river, it is naturally impossible for the Sui army to send a large army to besiege this smuggling force. Presumably, the Goryeo army also took a fancy to this, so it was so confident and bold to divide its troops to attack.

Luo Cheng frowned and said: "General Yu, this high mountain terrain is also dangerous, and it is a narrow and small road up the mountain, and it is estimated that it is a little difficult for individuals to walk side by side." If our army wants to storm strongly, it is bound to suffer heavy casualties. ”

Yu Ming didn't answer at this time, but carefully looked at the trees on the mountain and the road in the mountain, and then began to think.

After a while, he asked in a deep voice, "I see a lot of dry grass and trees on this high mountain, what do you think if you set fire to the mountain?" ”

"Amin, if you want to attack with fire, I'm afraid it's a bit troublesome. For if you set fire to the top of the mountain from the foot of the mountain, it will probably take at least an hour to burn to the top of the mountain, which is enough for the enemy to dig a fire barrier in front of the dense forest where they are hiding...... Unless it's set on fire directly in the jungle, I'm afraid there's still some hope. Eldest Sun Wuji frowned and said.

"Yes! And how to go to the jungle and set fires? The enemy will definitely be heavily fortified along the way up the mountain, and how can the people sent to set fire break through the enemy's heavy defenses? Wei Chi Jingde also retorted.

"Hehe, Jingde, Brother Wuji's words gave me an inspiration, we don't have to set fire from the foot of the mountain, but directly from the top of the mountain." Yu Ming's eyes rolled, and he suddenly thought of a clever plan.

"Put it from the top of the mountain? How did the man get to the top of the mountain? General Yu, I know that your martial arts skills are good, but if the enemy will definitely be heavily defended on the way up the mountain, I am afraid you will not be able to go up! Wei Chi Jingde hurriedly said.

"Ahem-ahem, when did I say I was going to go up on my own? I mean, we can set fire to it from the air......" Yu Ming said with a smile.

"Aerial fire? How do you put this? Can you grow wings and fly up? After Guo Yi heard this, he was also stunned.

Yu Ming pointed to the sky at this time and said: "I observed the direction of the wind, now it is a south wind, if we make a batch of Kong Ming lanterns, install fire starters in them, and then calculate the distance of the landing point, we can use them to ignite the already dry dense forest!" Then we don't need to attack the mountain, the enemy will run down by himself! At that time, as long as we guard the entrance to the mountain, we will be able to catch turtles in an urn! Burn all the enemies on the mountain"

After everyone heard this, they were overjoyed, and Wei Chi Jingde was even more overjoyed: "That's good!" I immediately went to assign tasks to the craftsmen and asked them to create a batch of Kong Ming lanterns immediately! ”

"Well, but we have to wait until the Goryeo army starts to attack, so that the enemy can't change their plans. Otherwise, when the Koreans know that their plot to plagiarize us has been shattered, they may have to come up with something more difficult for us to handle. The eldest grandson Wuji reminded.

Seeing that Yuming had only thought for a moment, the generals had so easily come up with a way to defuse the threat of the five thousand sneak attack on the enemy, and they all admired him greatly.

After returning to the camp, the generals began to prepare for the decisive battle according to Yuming's arrangement. Yu Ming confessed at this time: After the start of the war, let the 22,000 soldiers divide into batches and take turns to rest in order to maintain their physical strength.

…………

After another two days, the Goryeo army finally attacked. They gathered several rafts, carried about 5,000 people, and then began to cross the river.

Wooming did not intensively deploy defenses on the shore, but left a clearing for the Goryeo army on the river beach, and when the vanguard of the Goryeo army, 5,000 people, came ashore and was ready to start building fortifications, he suddenly launched an attack.

The early Goryeo army crossed the river with infantry, mainly pikemen, shield men, and archers, as well as some sappers. After they went ashore, their main task was to guard against the attack of the Sui army, and at the same time build fortifications to cover the crossing of the river by their cavalry.

The best way for infantry to defend against cavalry was to use shieldmen and pikemen. Defend against cavalry with shields, then pierce the armor of the cavalry with spears and knock them off their horses.

However, since Yu Ming dared to wait for the enemy's vanguard to cross the river before launching an attack, how could he not have a way to crack this set?

A brutal sniper battle across the river began.
