The leader of the Chahar tribe of Xilingol, Erke Konggol Ezhe, learned that the leaders of the five Inner Khalkha tribes had been assassinated one after another, and the various forces of the five tribes were fighting for the position of leader. Several weaker forces sent people to Chahar, hoping to get the support of Erke Konggol Ezhe, and promised to take the tribal leader as the main of the Chahar tribe.

Since Lin Dan Khan's death, Chahar's strength has plummeted, and Erke Konggol Ezhe has been worried about it. But this rebellion of the Five Divisions made him see a great opportunity for Chahar to subdue the Five Divisions.

"Chahar" is an ancient Turkic language, meaning "the guard of the Khan's palace", the full name is "Hao Chen Chahaner", which originated from Genghis Khan's youngest son Tulei and his wife instigated the subjects of Luheteni. Chahar is a very special part of the Mongolian tribes. His ministry began with Genghis Khan's founding of the Cowardly Xue Army and the establishment of a standing guard army, and the establishment of the Great Khan's Guard Army in the middle of Dayan Khan in the Northern Yuan Dynasty; Declined due to the failure of Lin Dan Khan's resistance to gold, and the discrete decline of the people.

The east of the Laoha River, the west of the Liao River, the Xilamulun River Basin and the vast grassland area north of it all belong to the grazing land of Chahar Wanhu. After the rise of the Later Jin in Liaodong, they began to face the Mongol tribes in Lingnan, and the then Lin Dan Khan of Chahar fought to the death with the Later Jin.

The five tribes of Nenkorqin and Nekhalkha, which originally belonged to the Chahar Department, also formed an alliance with the Later Jin regime, so that Lin Dan Khan was finally defeated by Huang Taiji, and Chahar was so far in a state of collapse and lost the ability to lead the Mongol tribes in southern Monan.

Since the Far East swept through Liaodong, the Jin regime, the Lingnan ministries have also contacted Chahar to deal with the Far East together. But Erke Kongguoer Ezhe is like a mirror in his heart, the Lingnan departments are bought on both sides, and if the Far East accepts them, these princes and Taiji will not hesitate to throw themselves into the arms of the Far East.

In the face of such a rare opportunity. Erke Kongol, of course, could not be missed. So he mobilized all the elite cavalry of the Chahar tribes, and contacted the Sunit, Dorot, Haochite and other tribes to form a horse team of nearly 100,000 people, and slaughtered the grasslands of western Liao.

The unexpected eastward advance of the Chahar Department was not expected by the Far East, after all, the strength of the Chahar Department has long since ceased to be the time of Lin Dan Khan. No one expected that Erke Kongol Ezhe of the Chahar Department would make such a big determination.

The first and second columns of the Western Army slowly advanced to the west, and everyone waited silently, hoping that this cold snap from Siberia would pass. In such weather, even two Cessna 208 aircraft stopped taking off. In fact, they can still take off, but even if they do, they can't carry out reconnaissance missions.

A few days later, the rain and snow finally ended, but the windy and cooling weather continued, and the airboat detachment was still unable to take to the air. The two caravan planes of the Air Department took off in turn, and one aircraft was always cruising over the theater of operations.

The two helicopters were also transferred to the forward base of the second column. The two helicopters alternated in the air to reconnoiter the situation on the battlefield as much as possible. After several days of patrolling and reconnaissance, several planes of the Air Force Department finally found the personnel of the Fifth Inner Khalkha Department and the three brigades of the Alu Korqin, Wengniut, and Keshiketeng Divisions that had moved westward.

In addition, the Song and special combat teams also set up more than a dozen special operations reconnaissance teams, drove off-road motorcycles deep into the vicinity of the Mongolian coalition forces, and constantly transmitted reconnaissance information back to the headquarters of the Western Army Corps

Based on the information sent back by the Air Force Department and the special combat team, Li Ming, Hao Changfeng, and others felt that the time was ripe for an attack. Therefore, when the Western Military Region issued the order to attack on all fronts, the units of the first and second columns immediately accelerated their march and killed the Mongolian coalition army composed of the five Inner Khalkha divisions and the three divisions of Alu Korqin, Wengniut, and Keshiketeng.

The allied forces of the Mongol tribes in order to protect the cattle, sheep, women and children who migrated westward. Desperately blocked the attack of the cavalry of the Far Eastern Army. The two sides fought desperately along the banks of the West Mullaren River.

Because there was no all-weather reconnaissance of the airboat detachment, the Western Corps of the Far Eastern Army did not use bold interspersions as before. In the end, the tactic of encirclement, but concentrated superior forces to carry out a frontal attack on the Inner Khalkha Division, hoping to defeat the Mongol coalition army as much as possible.

In order to intensify the attack, two Cessna 208 aircraft, two Robinson R44 helicopters, and eight delta-wing aircraft of the Air Department also participated in the battle, providing all-round air support to the ground forces, carrying 82-mm and 120-mm mortar modified bombs, incendiary bombs, and submunitions. An indiscriminate bombardment of the Mongol coalition forces.

The artillery unit also joined the attack with four rocket launchers, six 120-mm mortars, twelve 82-mm mortars, and dozens of 75-mm mountain guns and 70-mm infantry guns.

Tens of thousands of patchwork tribal cavalry, where are the opponents of the Far Eastern Army, armed to the teeth. When the armored assault brigade consisting of four BTR-60 armored transport vehicles and nearly a hundred jeeps, off-road vehicles and trucks went on a rampage. The coalition of tens of thousands of Mongol herders collapsed.

They abandoned their cattle, sheep, women and children, and fled westward regardless of it, and all units of the Far Eastern Army also tightly bit the scattered and fleeing Mongol coalition forces, and pursued and killed them for nearly 100 miles before collecting their troops.

In this battle, more than 30,000 Mongolian coalition troops were killed, wounded and captured, and the Mongolian coalition forces that fled west were also scattered by the Far Eastern Army, and they could not form combat effectiveness in the short term. Even if the various departments gathered their men and horses, they were frightened by the ferocious fire of the Far East, and they would never dare to turn back.

In addition, there are tens of thousands of old and weak women and children left behind in various Mongolian tribes, cattle, sheep, horses, wooden wheels and carriages as far as the eye can see, as well as a large number of leather goods, felt, jerky, grain and other materials. This is all the wealth accumulated by the Nayan of the Inner Khalkha tribes for many years, and now it has fallen into the hands of the Far East.

The two brigades of the Western Army Corps left the field division to take care of the spoils of war, and the rest of the main cavalry brigades, militia brigades and other mobile units all scattered in all directions of the steppe, sweeping the small tribes in the surrounding steppe.

Soon after the end of the war, the mobile cavalry units of the Western Army Corps dispersed to the grasslands west of the Liao River to sweep up, because of weather conditions, there was no all-round and all-weather reconnaissance and alert of the air boat detachment in the air, and the troops of the Far East and West Army Corps did not find that the 100,000 iron cavalry of the Chahar Department were killing the Xilamulun River valley west of the Liao River.

Several aircraft of the Air Department take off with an ultra-high frequency these days and are approaching their limits. As soon as the battle ended, several planes immediately returned to the Quang Ninh garrison area for maintenance, and at this time, there was no air power from the Far East to guard over the Lao Ha River and the Xilamulun River valley.

The vanguard sentinels of the Chahar Department have broken through to the upper reaches of the Xilamulun River, and the front of the troops is directed towards the Laoha River. At this time, the main cavalry brigade and militia brigade of the first and second columns of the Far East and West Army Corps were scattering and sweeping the small and medium-sized tribes scattered on the steppe.
