Led his troops back to the camp, Jiang Jie was already waiting in the camp on horseback, and when he saw Bailiyan coming, he stepped forward and gave a slight salute and said:

"Jiang Jie has seen adults!"

"No courtesy. The enemy on the east coast of Drangi is subject to change. ”

"The subordinate was about to talk about it. Two days ago, the Jin Xuedi people secretly transferred troops from the east coast, the number is unknown, and they should have come from the West Mountain,"

"Well, that's right. It's a pity that God doesn't help the thief, but helps me. The Jinxuedi people filled in all the swamps south of Xishan last winter, and now the rainy season has arrived, and the swamps have returned to the tide and become swamps again, and it will be difficult to increase their troops. ”

"Back to my lord, the water level of the West River has skyrocketed, and the river water has poured into many low-lying areas of the Delangi Pass, and the fighting has stopped."

In the spring, the upstream water volume increases, and after the downstream river rises, most sections of the Delangi Pass are flooded, and it lasts until autumn, the water level drops, and the mountain pass tidal flats are exposed again, so there are only a few months of winter and early spring, which can accommodate the brigade to pass, and the river water that is poured in late spring, summer, and early autumn basically submerge it.

The art of war: "The time is not as good as the location, the location is not as good as the people" Bailiyan felt that he was the right time and the right place and all three occupied, less than one, today's battle will be a fiasco, it can be said that the swamp is back, the Delangi Pass is flooded, and the oil is coming out of the back mountain, all three of them were not expected, and the victory is quite lucky.

Luckily, Bailiyan still didn't dare to be careless, and sent scouts to continue to test south, in case there were still trails in the swamp.

With such heavy rain, if you want to fill the swamp, the effect will not be too ideal, and last year, it took the Jinxuedi people nearly a month to fill the swamp, digging a huge ravine south of the swamp, and if you want to fill the earth, you must transport the earthwork from a farther distance, which is extremely inconvenient.

Of course, it is not that there is no other way, and this is exactly what Bailiyan is wary of.

In fact, as long as you cut down trees to make wooden rafts, find a swamp with decent ground, and build a pontoon bridge on top of the semi-thin swamp, you can disperse the pressure per unit area and increase the tension, so that you can pass through the swamp in a few days. But Jin Xuedi couldn't turn his head for a while, and he couldn't draw inferences, and it was almost difficult to think of erecting a pontoon bridge on the ground. Even if you think about it, you have to put it off for a while.

The fire in Houshan is still burning, but the fire is smaller than last night, and Bailiyan was still worried about whether it will develop into an oilfield fire. Once it becomes an oil fire, the oil gushing will continue to burn for years, and the longest burning oil fire in the history of the earth will burn for more than 50 years before it is extinguished.

With current technology, without TNT and nitroglycerin collapse wellheads, it would be almost impossible to extinguish oil field fires, and the air pollution and ecological disasters caused by them would be incalculable.

Almost unsurprisingly, the Jinxuedi people, reinforced from Derangi, arrived south of the swamp in the second half of the night, let alone 30,000 men, and were blocked in the swamp with no movement. After discovering that the back road was cut off by the swamp, Jin Xuedi, who retreated to the West Camp, tried to break through to the bank of the West River, but was driven back by Bailiyan's army.

According to his captive's confession, the enemy soldiers trapped in the western camp were the headquarters of the commander of the Sondia Auxiliary Legion, Cartenson, and he himself was trapped in the camp, with a strength of 13,400 men.

When the rain stopped for a while, Bailiyan asked people to go into the mountains to sweep away the remnants of the enemy and collect weapons and baggage.

Although the oil-induced fire burned the main mountain road in and out of the back mountain, it was still far from the wellhead in the center of the fire, so it only needed to cover the outer fire belt with muddy wet soil to extinguish it, and there was no big problem for the large group of people to pass.

Of course, it is not absolutely without problems, the smoke from oil is accompanied by a pungent and choking smell, and long-term breathing can damage people's lungs and liver. But now everything must give way to war, and we don't even know if we can survive until tomorrow, and it is undoubtedly nonsense to talk about people's physical health in war.

The sweeping situation of the back mountain is relatively smooth, the fire has burned the back mountain barbarians, the mountains are relatively isolated, Bailiyan does not attack the mountain, obviously the gains of attacking the mountain outweigh the losses, so people block the connecting mountain road, besiege it on the mountain.

The situation of the cave in Xishan was affected by the explosion of the oil field, and a large number of stones were rolled down by the landslide. The 40,000 barbarian troops trapped in the valley were dying, and they had reached the point of eating leaves and gnawing bark, and Gongliang Xiu and Gongliang Song's cousins only sent troops to recover the dumb flat land in Xishan, annihilating more than 10,000 people, saying that they were annihilated, but in fact they were lying on the ground and could not move, and there was not a single living mouth left, and they were all killed. The rest of the barbarian army continued to adopt the strategy of besieging but not attacking, only waiting for themselves to starve to death.

The grain in the valley has been out of grain for only a few days, and how to transport grain, grass and military supplies into the grain has become a thorny problem. It still takes a few days or even more than ten days to rush through the cave buried by the stone side, and before that, the grain will be cut out in the valley, and there are still three days to go from the west mountain to the valley, and it will take another day to send it to the cofferdam east of the valley.

A letter of Gongliang's repair book, let the scout send it over the mountain, and Bailiyan opened it and read it, which was an eye-opener:

"Genius, really genius, I can think of such a way!"

"My lord, what does genius mean?" Jiang Jie asked puzzled.

"Genius...... It is the meaning of the world's genius. There is a wonderful way to transport grain and grass into the mountains without much effort. ”

Sikong Nan said at this time:

"How can grain and grass be transported into the mountains without relying on people to carry them on their shoulders and without going through caves?"

"Haha, it's also a strange law, you'll know when you see it."

Bai Liyan handed the letter to the two, and Sikong Nan was taken aback at a glance:

"It's a wonderful way to send grain and grass into the mountains without much effort."

"Exactly, quickly dispatch 2,000 men and horses from the battalion, hurry to the twelve mile slope, and order people to block the mountain road and wait for the flood!"

"The last general obeys!"

Twelve miles of slope, is the west mountain back mountain east of six miles of sheep intestine trail, along the way the road twists and turns as long as twelve miles, the hillside path is vertical and horizontal, both sides are high mountains, can only accommodate a few people from this road to go around into the west mountain, the brigade can not pass.

Because both sides of the twelve-mile slope are high mountains, and there is no fork in the road, Gongliangxiu designed to block the exit of the west mountain of the twelve-mile slope, and then lead the mountain flood into the twelve-mile slope.

Bailiyan loaded grain and grass and other materials into the wooden carts or self-made rafts of the Jinxuedi people in advance, and when the water level was raised, the rafts and vehicles were lifted by themselves, and the water surface was wide at this time, which was enough to transport the wooden vehicles over the low hillsides and submerged paths into the halfway of the West Mountain.

In this way, only the grain and grass need to be transported up the mountain, which can eliminate a lot of manpower and shorten the transportation time. You don't need too much food and grass to need, as long as you can solve your urgent needs, drag them to the cave and open them up.

For this reason, as early as the day of the cave collapse, Gongliangxiu blocked the mountains and rivers east of the West Mountain, introduced mountain springs, stored rainwater, and cut down wooden rafts to divert water to flood into the Twelve Mile Slope.

Bailiyan ordered people to cut down and sharpen the tip of the wood in the narrowest place and insert it into the ground, a layer of gravel and grass and a layer of mud, rammed layer by layer, and at the same time build a raft, transfer thousands of stones of grain and grass and put it in the raft and wood cart, Gongliang Xiu released water upstream after three days, and the flood water quickly poured into the lowland, and overflowed to the embankment in half a day.

The rafts and wagons on the ground floated on the surface of the water under the action of buoyancy, and the soldiers supported the wooden oars removed from the boat, and it took less than two hours to cover the hills that had been crossed two days before.

Bailiyan arrived at Xishan on a raft, and Gongliangxiu had been waiting for a long time. For this wizard of his age and a handsome face, he is full of respect:

"Major General, don't come unharmed!"

Baili Yan gave a slight salute, and Gongliang Xiu returned the salute:

"Yan Gongzi came as promised, and Xiu is grateful."

"The major general said seriously, our army was late, and the grain was cut off, and Yan was very ashamed."

"The enemy is outnumbered, how can it be the responsibility of Yan Gongzi. It's raining heavily, Yan Gongzi, please come with me. ”

When he came to the thatched hut on the mountain with Gongliangxiu, Baili Yan drained the rain from his body, and asked non-stop:

"I've read the letter roughly, and I don't know what the situation in the valley is."

"The Soviet division was very difficult at the Dongshan cofferdam, the enemy army increased tens of thousands of troops and attacked the mountain, our army was short of weapons, and there were more than 100,000 people here. Therefore, it is very difficult to fight in the north and south mountains of the cofferdam, and only this west mountain is acceptable.

But there are still less than 30,000 enemy soldiers besieged by me in the mountains, and for another day or two, most of them will die of illness and starvation in the rain. ”

"The Derangi Pass was flooded by the water of the West River, and the enemy could no longer fight, so the tide of the battle slowed down, but nearly half of the casualties were not a good sign in the long run. Moreover, the hearts of the new annexed army are fluctuating, and I am afraid that it will change for a long time. ”

Bai Liyan explained the details, and Gong Liangxiu continued:

"At present, the overall situation is tentative, and Yan Gongzi can have a long-term strategy."

"No, if the young general has a good plan, Yan is willing to hear about it."

Gongliang Xiu scooped up his wet long sleeves, put the candle in front of him, spread out the map and said:

"Yan Gongzi, look, the topographic map of the mountains and rivers in the eastern part of Posong Province drawn by the people of Jin Xuedi is extremely fine, can you find the mystery?"

Gongliangxiu's map is not much different from the map held by Bailiyan, if you want to look at the map, Bailiyan has already understood it in his heart, and he really can't tell what the mystery is.

"Yan Yan is clumsy, please also ask the major general to make it clear."

"You see, the great rivers in the eastern part of the Jinxuedi people all run north-south, flowing from south to north. More than a dozen large rivers divide it into several plains or mountains, and the north-south rivers are connected by east-west rivers, so that the plains and mountains are divided from east to west.

In this way, although there is a large area of land between the rivers, it is divided by the river, so if the river can be cut off completely, the land between the two rivers will be the land of death, and their grain and grass and military supplies will not be able to operate, and once they eat up the grain and grass, they can only sit and wait for death. ”

"Oh...... I see. After seizing the Jinxuedi warship, he also had this idea, and if he could cut off his land and water points, the supply of military supplies for his people and horses would be restricted by our army, but only with more than 100 warships of all sizes at present, I am afraid that it will be difficult to block all the rivers in this huge basin, so it will be difficult to implement it in a short time. ”

"No, our army doesn't need to do this in the short term. The enemy army is now heavily concentrated in Qiu Bigong and Delangi, and as Yan Gongzi said, their rear is extremely empty. The commander of our army has confronted him in the past, and he has been deceived by his attrition.

Our army has a limited number of troops, and the people of Jin Xuedi know that their strategy and tactics are inferior to our army, and they will definitely use the method of attrition to deal with us. Therefore, our army needs to take advantage of the fact that its heavy forces are gathering here to send a naval army to the west, attack and attack its rear, and force it to transfer troops to the west, so as to reduce the frontal pressure on our army. At the same time, they plundered their warships and captured the people of the Central Plains to strengthen our army.

Just as the Gongzi Shao Ping's tactics of war were done in this way, our army can also do it now. ”

"Shao Ping's tactics, our Xian army has a large rear to rely on, and the Black Turban Army has no water army, which is certainly feasible. However, now our army is alone, and even if the navy is strong, it is difficult to act in the face of ten times the strength of its own troops. ”

"No!" Gongliang Xiu shook his head and continued: "Have you forgotten that most of their sailors are attracted to the front of our army, and most of them are probably dead in battle, so their sailors will be useless in a short time before their ships are loaded with sailors. Therefore, if the general led the naval army to the west at this time, I am afraid that he would suffer heavy losses and capture a large number of warships on his inland rivers in one fell swoop. ”

"This ...... It's doable. At this time, its troops were all contained here, and the ships in its hinterland were probably seriously understaffed, or they were all merchant ships, and the westward advance was indeed taking advantage of the weakness at this time. ”
