According to the experimental data, the probability of fog will be reduced to 80%. If the wind blows, the probability of fog will drop to 60%. If the wind blows the branches, the water vapor will most likely disperse..." Zhao Ting'er said.

In the previous book, Li Chunfeng conducted a preliminary study on the climate phenomenon of wind, and divided the wind strength into "no wind, gentle wind, wind that moves leaves, wind that sings strips, shakes branches, falls leaves, breaks small branches, breaks big branches,"

"Breaking trees, flying sand and stones, and uprooting large trees" are divided into ten levels.

The Institute of Technology now has more accurate measurement methods, but the wind classification still follows the old rules.

The research on weather prediction at the Institute of Technology has just begun, and it is far from accurate. That is to say, the conditions for the formation of heavy fog are relatively simple. At present, there are some feasible results, but it has not yet formed a weather prediction system.

, the comprehensive schools in Liyang and Luoyang, the soldiers and horses in various towns, and the Military Intelligence Staff Office have not yet been promoted...

It is a conventional tactical arrangement to take turns entering the front line to fight in order to effectively reduce the physical consumption of generals, share casualties, and carry out timely and effective troop replenishment.

After Liang Jun exchanged flags, he arranged three reserve brigades to the forward line in the afternoon to replace the three main infantry brigades, and later sent two more reserve brigades to the forward line. It was difficult for the Mongolian army to see anything unusual.

Wusu Dashi did not want to see the Mongolian army on the forward line being forced back by Liang Jun again. He did not want to see

Liang Jun was more comfortable deploying his troops in the open area in southern Jiangxian County, and even pushed the frontline to the foot of Jiangxian County. He only mobilized his troops accordingly and strengthened the deployment of forward troops along the two wings of Jiangyuan Post Road.

After nightfall, through the dense torches, I saw signs that a large group of Liang troops had climbed over the mountains on both sides to outflank and attack the flanks of the forward line. Wusu Dashi also sent additional troops and horses behind the crude defenses on both sides of the forward line. Unknowingly,

, both sides accumulated a large number of troops in the forward line and on both wings.

At midnight, the sky was calm and windless, and clouds of mist first rose from the Fenshui River, and then spread out on both sides.

Since the Luoyang Navy controlled the Fenshui River, except for a small number of scout cavalry, the Mongolian troops were stationed far away from the river bank.

There is often heavy fog in the Fenshui River Valley in autumn and winter, and the scout cavalry did not realize that there was anything unusual about the fog spreading along both sides of the river after midnight or anything that warranted vigilance.

They were just closer to the river bank than before, watching Liang Jun's warships for any movement. They didn't even notice that the night battle launched by the two armies on the forward line forty miles away had anything to do with the mist rising along the river at this time.

contact directly.

From a distance, they saw several Kongming lanterns rising over the Fenshui River, confirming that there was heavy fog along the river. Under Wen Bo's instructions, Cao Ba and Lu Ze turned over and mounted their horses.

Their combat mission is to lead 3,000 elite troops each to cross the valley slope trails about twenty miles long on both sides before dawn, take the lead in launching a surprise attack on the enemy's troops and horses on both sides of the forward line, tear open the openings, and then cover the enemy's forward line.

The elite 40,000-strong main infantry brigade entered the preparatory formations on both wings and penetrated directly into the depths of the enemy's army along the open areas on both wings of Jiang County. They rushed to raid the two Mongolian cavalry camps before the fog dissipated.

Both sides gathered too many soldiers and horses in the valley southeast of Fenshui River, and the city of Jiangxian County was strong but small and could not accommodate so many soldiers and horses. What's more, Wusu Dashi was definitely not going to fight a defensive battle and just sit back and watch Liang Jun's battle in Jiangxian County.

Set up camp in the south.

In addition to the guards and horses of Usu Dashi, the main force of 90,000 Mongolian troops was mainly camped on the two wings of Jiangxian County and on the forward line to resist Liang Jun's further northward advance.

Wu Su Dashi and Xiao Yiqing noticed that the fog in Jiangxian County was getting heavier and heavier after an hour, but they did not arouse enough vigilance. After all, the foggy weather was an equally unfavorable neutral factor for both armies.

While he ordered all ministries to be more vigilant, he also expected that Liang Jun would become more cautious in the face of sudden changes in weather.

The night battle that was hastily launched on the forward line was temporarily suspended as Liang Jun retreated, which seemed to be in line with their predictions.

If it weren't for his usual caution, Wu Su Dashi would have wanted to go back to the bedroom to rest.

When Wu Su Dashi and Xiao Yiqing noticed the abnormality, it was the generals on both sides of the forward line who noticed that Liang Jun's advance in the valley was not interrupted by the heavy fog, but the sky was already dim at this time.

, the heavy and wet fog had water droplets condensing on the window paper, and when I opened the door, I couldn't even see clearly the scenery in the two-foot-square courtyard.

After the heavy fog came up, the torches in the distance were obscured and could not be seen. The scouts on the two wings inspected the horses and judged from the noise in the areas controlled by the two armies that Liang Jun had been massing to the south of the two wings of the forward line, and the scale was huge, far exceeding

beyond their expectations.

Xiao Yiqing stood up in shock. Liang Jun had predicted the heavy fog today and had already planned and deployed to launch a surprise attack from both wings while the fog was heavy.

"All the messengers are dispatched immediately, and the generals in the forward line and the camps on both wings are ordered to immediately form formations to defend against the enemy!" Wusu Dashi shouted loudly.

The camps on the forward line were too simple, with simple fence walls or thin rammed earth retaining walls plus shallow trenches and narrow trenches, and they could be easily broken through without the need for any combat equipment.

And in the heavy fog, even a bonfire cannot shine far.

Although there are ways to communicate and identify directions in the heavy fog, the problem is that Liang Jun came well prepared and was more adequate than them in these aspects, and the pawns on their forward line may have dispersed.

After entering the camp to rest and gather in a hurry, is it possible to be fully prepared for the battle?

The generals of the various tribes had no choice but to gather together as much as possible, form a ring formation, and do everything possible to avoid falling into chaos. This was the only way to prevent Liang Jun from launching a surprise attack while taking advantage of the heavy fog.

In order to prevent Liang Jun's scouts from infiltrating and intercepting the cavalry, Wusu Dashi also ordered the soldiers on the tower to beat the war drums and blow the horns as a warning.

Xiao Yiqing followed Wusu Dashi up to the south city tower, and saw a vast mist between the sky and the earth. The scenery ten feet away was completely covered by the fog. His heart was like the bottom of a well, and soon there were beams on both wings.

The news that the army had made a sudden attack made their faces darken even more.

"The Hufeng Camp on the right wing was defeated by Liang Jun. The casualties of soldiers on both sides were unknown. The camp was set on fire by Liang Jun. All the soldiers escaped. Liang Jun seemed to be heading towards Yujiagou..."

"The Jia Feng Camp and the Guishan Camp on the left wing were defeated by Liang Jun, and Liang Jun seemed to be heading towards Tianwa Bay..."

The unfortunate news came one after another, deafening them like thunder.

"Liang Jun is heading towards the cavalry camp!" Xiao Yiqing said in shock.

Although the information passed back was confusing, it was not difficult for him to analyze the intentions of Liang Jun's troops who attacked from both wings.

The terrain in southern Jiangxian County is still dominated by shallow and low hills. The forward line and two wings are dominated by the infantry of the Yanyun Han Army and the surrendered army. The cavalry camp is deployed on the rear flank of Jiangxian City. It is the wing that looks forward to the step by step general Liang Jun.

Advance to Jiangxian City, and then use cavalry to attack its flanks from the open valley.

It was too foggy to go out into battle, and now tens of thousands of cavalry were huddled in several companies on both wings.

It was not considered that Liang Jun's infantry and cavalry dared to penetrate so deeply in the early stage. At the same time, the cavalry was not used for defense. The company's defense facilities were extremely crude. It was suddenly attacked by enemy troops and could not form a formation to fight in heavy fog.

There is no way to break through, and God knows what kind of chaos it will be like after being attacked by Liang Jun.

"Quickly order Zhehe and Minshan to abandon the camp and go to Quwo with their troops. Upon hearing the news, the three areas of Yicheng will disperse and no head-on battle will be allowed!" Wusu Dashi ordered.

The cavalry comes and goes like the wind. There will be no loss if the camp is abandoned. It will be convenient to regroup when the fog dissipates. Otherwise, if you engage in a melee with a well-prepared enemy in the fog, you don't know what will happen to you.

Look!

Seeing several soldiers coming out of the city gate, riding deep into the fog, rushing to the cavalry camp to deliver orders, Xiao Yiqing felt worried and difficult to leave; if this raid had been planned by Liang Jun, then he realized that it was

The navy soldiers and horses had most likely landed ashore and formed a formation on the flank of the cavalry camp to intercept them.

In such foggy weather, it is difficult for the cavalry to organize a decent attack. Once intercepted and confused, most of the cavalry will deviate from the main road and lose the ability to discern direction. At that time, they can only fall into separate formations.

In a chaotic war, the consequences will be disastrous.
