The Silamulun River, in Mongolian, means the yellow river. It is the northern source of the West Liao River, originating from the Baigou River at an altitude of 1420 meters above sea level at the north foot of the Red Mountain of the Keshiketeng Banner in Chifeng City, the Great Xing'an Mountains, and flows through the Keshiketeng Department, the Wengniute Department, the Bahrain Department, and the Alukorqin Department, and merges with the Laoha River to become the West Liao River at the junction of the Wengniute Department and the Naiman Department. The total length is 380 km.

The Xilamulun River Basin is located at the junction of the southeast of Inner Mongolia and the west of Liaoning, which is the transition zone from the Mengxin Plateau to the Liaohe Plain, as well as the agricultural and animal husbandry ecotone and the loess-sand transition zone, which belongs to the semi-arid and semi-humid region of northern China. The main rivers in the area are Xilamulun River, Laoha River, Wuerji Mulun River, Daling River and its main tributaries Jiaolai River and Chaganmulun River.

This also brought a lot of convenient conditions for the operation of the Western Corps. The river steam deck barges of the inland river detachment could enter the Xilamulun River and the Laoha River and their tributaries from the Xiliao River, and the Western Corps could use these rivers for the transportation of troops and supplies.

A large number of river steam-deck barges of the first column of the Western Army Corps sailed into the Xilamulun River through the Xiliao River, landed in the middle reaches of the river, and established an advance base on the south bank of the river. Also arriving at the same time as the flotilla were the 1st Brigade of the Field Division, 1 Armored Brigade of the Corps Headquarters, and 1 Artillery Brigade. In addition, the cavalry units under the first column include two Outer Northeast Indigenous Cavalry Brigade and four Outer Northeast Indigenous Militia Brigade.

The second column's inland steam-deck barge fleet sailed through the Xiliao River into the Laoha River all the way to the eastern area of the Zhaowu Dameng. Also arriving at the same time as the flotilla were the 1st Brigade of the Field Division, 1 Armored Brigade of the Corps Headquarters, and 1 Artillery Brigade. The main cavalry consisted of two Mongolian cavalry brigades, and four Mongolian militia brigades advanced all the way to the Zhaowuda League.

The third column of the river steam deck barge fleet went north along the Daling River, one landing in the middle reaches of the Daling River, the other sailing north into the tributary and landing near Zhenyibao, accompanied by two overseas brigades and an artillery brigade. The main cavalry consisted of one Mongolian cavalry brigade and four Mongolian militia brigades.

Because the area where the Western Corps fought was closer to the Quang Ninh garrison. Two Cessna 208 Caravan amphibious aircraft and two Robinson R44 helicopters from the Air Department will be on standby at the airport in the Quang Ninh area to provide them with air support at any time.

After receiving the order, the various columns of the Western Legion launched an attack almost simultaneously, and tens of thousands of iron cavalry attacked and advanced all the way to the west, and countless small and medium-sized tribes along the way were easily wiped out by them. Three columns of barge detachments on the river steam deck. They are also driving at full speed to the predetermined location, preparing to set up a forward base.

Nearly 100,000 troops from the far east and west marched westward, with momentum like a rainbow and invasion like fire.

At this time, the Mongolian tribes in the western steppes also suffered heavy losses in last year's white disaster. Therefore, after the beginning of spring this year, the grassland is not peaceful, and the tribes on the grassland fight and plunder each other in order to survive, and there are many small and medium-sized tribes who go south to go to the Han people to fight grass valleys.

Of course, the Guan Ning army of the Ming Dynasty also knew the news of the white disaster on the grassland last year. They have also responded adequately. The northern winter was plagued, and the Mongolian tribes on the steppe in the spring of the following year were bound to raid the south in order to survive.

Not only Liaodong, but also the border troops of the Ming Dynasty this year are actively responding to the southward movement of the Mongols. The Ming court has long been accustomed to such things, as long as it is not a large-scale southward movement of northern Mongolia, and a small group of tribes going south to fight grass valleys, it is a problem of scabies for the Ming Dynasty.

The grassland tribes near Yizhou in western Liaoning, they could only plunder the Far East Control District east of the Daling River when they went south. Although the Far East is also famous in the steppe. But the small and medium-sized tribes on the grassland were extremely severely affected, who cares about that. They were for the southward march to the grassy valley. I have long been accustomed to it, and even in the post-Jin regime, such things happened from time to time.

However, the Mongols who went south this year are considered to have fallen into blood mold, and the Far East and West Legions have hoarded tens of thousands of heavy troops here, and these Mongols have not yet entered the borders of the Far East. was stopped head-on by the Far East and West Legions.

Hao Changfeng successively sent dozens of soldiers of the Mongolian cavalry brigade to warn the western steppe tribes, asking the steppe tribes to control the tribes below, and if a small group of Mongolian tribal cavalry was found to intrude, the Far East would send a large army to sweep the steppe.

The major tribes received a warning from the Far East. I'm also nervous. They sent a large number of cavalry to the various parts of the steppe to severely suppress them. But to be honest, they can't do anything about it, even if the leaders of the small and medium-sized tribes listen to it, they can't restrain the harsh herdsmen of the various tribes, and the wives and children of the harsh herdsmen's families are waiting for them, and they have no way to live except looting.

The grassland is so big, you can't even look at it. They numbered as little as thirty or fifty to as many as a thousand eight hundred, mounted on horses and bows, and marched south in groups to plunder.

Of course, Hao Changfeng also knew what was going on, so he warned, protested, and threatened one after another, but he didn't send troops, so that the grassland departments didn't take it very seriously. Wasn't it the same when the Jin regime was there, and no one could change the situation in the Central Plains for thousands of years.

With the assassination of the leaders of the five Inner Khalkha tribes, the tribes of the Laoha River and the Xilamulun River basin began to revolt. The tribes were suspicious of each other, and the forces of the various tribes were running around preparing for the position of chieftain.

Among them, some relatively weak forces sent people to contact Erke Kongol Ezhe of the Chahar Department of Xilin Gol, hoping that the Chahar Department could help them seize the position of the head of the tribe, and as long as they mastered the tribe, they would respect the Erke Konggol Ezhe of the Chahar Department as Khan.

In 1634, Lin Dan suffered from a pox and died in Xilin Gol. Erke Kongol Ezhe of the Chahar Division, with the support of his mother Lin Dan Khan Fujin Sutai, became the new lord of Chahar Bu. But at this time, the strength of the Chahar Department is now much worse than before, and the eight Etoke of the Chahar Department have been sentenced to return to the Houjin.

The Far East swept through Liaodong and eliminated the Later Jin regime in a few months, and the Mongol tribes in the eastern part of the Great Khing'an Mountains also allied with the Monan tribes, hoping to deal with the Far East together with Chahar and other departments. However, the grassland tribes east of the Daxing'an Mountains, headed by the Nenkorqin Department and the Inner Khalkha Department, did not dominate the Zunchahar Department as before.

In this way, of course, the Erke Konggol Ezhe of the Chahar Department would be dissatisfied, making this alliance a gathering of various departments of the steppe to talk nonsense. The alliance is in name only, what should everyone do.

But this time there was chaos in the five departments of the Inner Khalkha, Erke Kongol Ezhe received a request for help from the various departments, it is impossible for him not to be moved, if he gets the annexation of the five departments of the Inner Khalkha, the strength of the Chahar Department is bound to increase greatly, and he will also be like his father Lin Dan Khan, who will unify the various tribes of Southern Mongolia.
