In the autumn of the twelfth year of the Great Cause, the north wind was sluggish.

The Loyal Army, which had been gathering momentum for a long time, was completely ready for mobilization.

After a busy autumn harvest, Luo Cheng mobilized 100,000 soldiers and horses to participate in this crusade against the Yuan clan.

The three divisions of the Marshal's Office work together like a sophisticated military machine.

On the long front from the Liao River in the north to the West Liao River and to the Lushun Bay in the south, 100,000 soldiers and horses spread out in an orderly manner, and they slowly but orderly revealed their sharp edges.

On the southern coast, Daliangshui, Xiaoliao River, and Liaohe River, the four major corps soldiers are divided into four routes.

The battle cry of recovering Liaodong and never ending the future was spread all over the four fields, burning from Bohai Bay to the Fuyu River.

Luo Cheng personally sat in the Liaodong Marshal's Mansion to be responsible for the overall planning, Luo Shixin commanded the First Army, Li Jing was the marching staff officer, and Qin Qiong, Wei Chigong, Shan Xiongxin, Cheng Yanjin and other fierce generals cooperated.

And the Fourth Army of Luo Cunxiao and Xu Shiji, the Third Army of Feng Xiaoci and Murong Changsheng, and the Second Army of Zhao Gui and Xue Wanche successfully made the Yuan clan think that this time the loyal army was going to attack on all four fronts at the same time. Yuan Taizuo then deployed defenses in all directions, and each deployed heavy troops to defend.

Although in order to deal with this attack, he mobilized all the 100,000 soldiers and horses of the Yuan clan, and also mobilized 100,000 young and strong followers again. However, it did not take long to disperse the various battlefields.

Not to mention, Lelang Taishou Yang Wanchun died of illness during the autumn harvest, and Song Laosheng, the general of the Zhongwu Army, successfully took over Lelang County with his original 2,000 soldiers and horses in Pyongyang, as well as the 4,000 soldiers and horses he brought.

Therefore, now the 50,000 Goguryeo army under Yang Wanchun of Lelangyuan is now also commanded by Song Laosheng, although after Song Laosheng took over the Taishou of Lelang County, he began to dismantle about 30,000 old and weak Goguryeo soldiers, but what was left and what he brought still formed a whole army.

Song Laosheng served as the military envoy of the Fifth Army, Guo Xiaoke served as the deputy military envoy, and Su Dingfang served as the staff officer of the march.

The Fifth Army held Pyongyang, with a population of more than 1 million and 24,000 soldiers and horses, directly threatening the national capital of the Yuan clan along the Yalu River.

For this reason, the Yuan clan had to leave 50,000 soldiers and horses on the Yalu River.

In this way, he also had to garrison 50,000 troops in the inner city to serve as a general reserve.

In this way, the Yuan clan has a total of only 100,000 horses on the four fronts in the west, and once it is divided, there are more than 20,000 people on each road, which is equivalent to Luo Cheng's troops. And he also had to divide his troops to garrison hundreds of mountain cities, so his troops were even more stretched.

And the Yuan clan didn't know that Luo Cheng's target for this attack was only Fuyuchuan.

In the other three roads, only 10,000 people are stationed on each road, stationed in the castle that was built before.

In the Buyeo River battlefield, not only did the First Army directly transfer 20,000 horses, but also the Second Army and the Third Army each transferred 10,000 people, and there were more than 20,000 tribesmen and tooth soldiers in the north.

If you add the river fleet of the sailors, thousands of people.

So on the battlefield of Fuyuchuan, Luo Cheng actually mobilized a total of 80,000 soldiers.

At the beginning of the campaign, Li Jing suggested that the cavalry should be sent to cross the river on the border and directly approach the city of Buyeo to surround it.

Then the rest of the troops and horses followed, ready to besiege the city and send reinforcements, and at the same time cut off Buyeo from the other cities.

Immediately afterwards, more than 20,000 Han legions in the north led by Qin Qiongwei Chi went south and used the strategy of cavalry attack to attack the villages and towns outside the cities of more than 40 cities in the middle of the Fuyu River.

The seizure of population and food outside the city is not only to attack the enemy, but also to supplement the war with war.

Previously, the Zhongmu Army did not do anything about the grain of the Goguryeo people in Buyeogawa, it was for their own use in wartime, and it would be wasted if they were burned and destroyed.

Anyway, just after the autumn harvest, it is impossible for the Goguryeo people to return to the city.

Yuan Jiantu cowered in Buyeo City, not daring to go out of the city to fight.

He was reluctant to give up the rest of the cities, so he simply ordered all the troops to garrison their own cities, and they must be strictly guarded. As a result, tens of thousands of soldiers and horses were scattered in more than 40 cities in the Buyeo River.

Li Jing only built a fortress on several key river valley roads, and then divided his troops to guard them, so that he could divide these dozens of cities, and then he could besiege the big city of Fuyu with all his strength.

As long as Buyeo City has no soldiers to help, then it is a lonely city and a dead city.

With all his strength to capture Buyeo, the other cities were just a mess of scattered sand, without support.

If it was during the First Crusade, it would have been very difficult to capture a large city like Buyeo. This is because the Sui army at that time was not accustomed to the climate of Liaodong, and many tactics were not adapted to the situation here, especially the emperor was always engaged in remote command, and even sent envoys to each army.

But this time is different.

Luo Shixin was awarded by Luo Cheng as the envoy of the First Army, and he was also the chief general of the Fuyuchuan battlefield this time, whether it was from the first, second, or third and fourth armies, or from the local regiments of various counties, or the township soldiers of each county, or the soldiers and horses of the water division, as long as they arrived at this battlefield, they were all controlled by Luo Shixin.

Luo Cheng will not interfere in the war.

On the other hand, Luo Cheng's support for logistics, grain, grass and ordnance is sufficient. As a front-line base, Tieling Town hoarded a large amount of grain, grass and ordnance early, and the five forts on the front line were also full of grain, grass and ordnance.

Even through the Liao River water transported many catapults and siege crossbows.

Several generals of soldiers and horses gathered at the foot of the Buyeo River.

In the military tent of the Sui army camp, the young Luo Shixin was only eighteen years old, and it was the first time he held such an important position as the chief general. Although from ten armored cavalry, and finally to command 3,000 heavy cavalry, but at most 3,000 heavy cavalry.

This time, however, he became the commander of the 80,000 coalition forces.

Fortunately, he has staff officers like Li Jing, deputy marshals like Zhou Dewei, fierce generals like Qin Qiong, Wei Chigong, Shan Xiongxin, and Cheng Yanjin, as well as warriors like the eldest grandson Wuji Li Xuanba.

"General, we have successively captured five small cities on the flat land in the Buyeo River and beheaded more than 2,000 people, and now the soldiers and horses of the rest of the cities of Goguryeo have shrunk and are afraid to come out. Next, how do we fight? ”

Wei Chigong asked directly, he was Luo Cheng's deputy general of the Ya Army, the deputy commander of the Ya Army, and he was a box-level officer.

But in the face of Luo Shixin, a young general, he was still a little unconvinced, after all, there were not enough records in the past to suppress them.

Luo Shixin noticed that many generals were looking at him, and he also knew that everyone did not trust him as the main general.

"Originally, the position of command should be in charge of the marshal, but now the marshal is the Shangshu order and marshal of the imperial court, and he has all the opportunities, not only our loyal army marshal, but now he also has to manage the Xuanwu army, the Yiwu army, the mighty army, the town navy and the Xiongwu army in the south of the Yangtze River, so I was given to command the war, everyone here is older than me, and the generals are also better at fighting than me, but since it is the marshal's order, then I and you should obey it."

After some words, Luo Shixin said directly, "Now that the Central Plains is in chaos, it is impossible for my loyal army to stay in the gate for a long time, but if the Yuan clan does not fight for a day, it will be a threat for a day, so we must first get rid of the troubles before we can send troops." I don't have much nonsense to say, Dashuai has already made all preparations for us, so what I need to do with everyone here now is to take Buyeo River as soon as possible, regardless of everything. ”

"Three days, within three days, attack the Buyeo River, please join me with your life and fight to attack the city!"

The generals couldn't imagine that Shixin could say such a thing, and they all claimed that they dared not to die!
