Russia has more than 500,000 troops in the Far East, including 300,000 troops stationed in Outer Mongolia and about 50,000 in the trading area, 100,000 in the Ulianghai area, 50,000 in Serwusu, 50,000 in Uriya Sutai, and 50,000 near Nebuchu.

The remaining more than 200,000 soldiers were placed in the Vladivostok region and the Sakhalin area, of which Sakhalin had the largest number of soldiers, as many as 130,000, while Vladivostok had only 110,000 troops, and these were mainly deployed against Japan.

In addition to preventing the Japanese, the army in Vladivostok also meant to deter Xu Lanzhou and the entire Northeast, and the Russians did not want the Northeast to be truly controlled by the Chinese Empire, otherwise their interests in the Northeast would be seriously threatened.

This time the commander of Russia was Nikolai Nikolayevich, the imperial uncle of Nicholas II, Grand Duke Nikolai, a cavalry general, with high military talent. The Tsar, because he was not worried about the Far East, especially the Chinese Empire, sent Grand Duke Nicholas, who was serving as commander of the Janissaries and commander of the Petersburg Military District, to the Far East.

Whether it is from the perspective of national defense strategic position or from the economic and cultural exchanges between the interior and various parts of Outer Mongolia, Selwusu is in a very important position.

From Sailwusu to the southeast through Zhangjiakou can reach the imperial capital of the Chinese Empire, northeast through the political, economic and cultural center of Outer Mongolia Kulun can reach the Sino-Russian border trading city, northwest through the military towns of Uriya Sutai and Kobdo, by three roads to the Xinjiang region.

Due to the importance of Serwusu, Tsarist Russia deployed here, and there were more than 20,000 Outer Mongolian troops inside, and these Outer Mongolian troops were established with the help of Tsarist Russia, and the actual leadership was the Tsarist Russian army.

Although this place is very important, the Tsarist Russia did not concentrate too many troops here, in their opinion, 50,000 imperial troops and 20,000 Outer Mongolian troops can deal with the Chinese Empire for a while, they don't think that the weak yellow monkeys will come to attack them.

On the evening of July 25, Jiang Fangzhen sent a telegram order to the three major armies of the counterinsurgency army to send troops to Outer Mongolia, and the meeting place was Serwusu, and the task was to break through Serwusu, a military stronghold of Tsarist Russia.

"Report to the commander, the headquarters has an urgent order, you see." The communications soldier ran into Ma Qi's camp sweating profusely and said.

Ma Qi didn't say a word, he directly snatched the order and looked at it, and after he finished reading it, he immediately shouted: "Come on, immediately call all the generals here for a meeting, quick!" ”

Several of the commander's guards at the gate immediately ran away, and they were going to summon the generals to the commander for an emergency meeting. After a while, the generals arrived at the commander's camp, and they were very curious about how the commander could summon them so urgently, could something important happen?

"Report to the commander, everyone is here."

"Ladies and gentlemen, just now there was a telegram from the headquarters, and the army is ready to send troops to Outer Mongolia, and the army will gather in Serwusu. Now I order, in an hour, to depart immediately, during which time no one who is not a telegraph officer shall be forbidden to approach the station, and no soldier shall be allowed to go out of the barracks during this period, and shall be brought directly before a court-martial. Ma Qi said very cautiously. The prohibition of the soldier from approaching the radio station and going out was mentioned in the order, and he also knew that it was a precautionary measure to prevent leaks.

Ma Qi took the telegram sent by the headquarters and showed it to the officers and asked them to prepare, it was not long before the time to send out the troops, and the logistics had to keep up, and it was not easy to rush to attack overnight.

The same thing happened to the First and Second Armies, the urgent orders kept them busy, and they did not have too much doubt about the orders of the headquarters, even though His Majesty had already issued a plan to delay the battle, but at that time His Majesty Xià also said that the first qiē operation was under the command of the commander-in-chief of the headquarters, Marquis Chiang.

An hour later, the armies of the three major armies began to move rapidly towards Serwusu, and according to the distance, it would be Duan Qirui's Second Army that would arrive first, because they were not far south of the destination, and it was estimated that they would arrive in a few hours.

The headquarters gave the order for a sneak attack, and the three major armies put the infantry at the front, the tanks at the rear, and the cavalry of the Third Army at the rear, in order to reduce the casualties of the imperial soldiers.

Duan Qirui and his army finally arrived near Serwusu after several hours, it was just the middle of the night, and most of the residents of Serwusu were forcibly relocated to another place by the Russian army, so the movements of the Second Army were not detected.

When the Second Army arrived nearby, it did not rush to attack the Tsarist Russian army inside, but only sent the special forces of the Second Army to clear the obstacles, otherwise it would have been easily exposed.

Dozens of special forces soldiers shuttle through the dark night like ghosts, looking for the Outer Mongolian soldiers and Tsarist soldiers standing guard in the shadows, and it takes great skill and luck to avoid attracting the attention of the garrison.

Soon after they walked, they saw a few Outer Mongolian soldiers napping in a sentry post, and only two soldiers were listlessly patrolling the surroundings, yawning from time to time.

In the darkness of the night, they couldn't see anything clearly, and the special forces didn't make contact with each other, but they just tacitly crept into the vicinity of the station, and the enemy inside didn't notice their existence.

Finally there was light, a few special soldiers were silently gesticulating, and then these soldiers slowly approached the napping Outer Mongolian soldiers, and the few soldiers who were secretly hiding took small bows and crossbows and aimed at the two patrolling soldiers, and when the special soldiers arrived at the sentry box, they began to shoot.

The sound of "Huh~~~" and "Huh~~~" sounded, and several bows and arrows shot straight into the heads of the two Outer Mongolian soldiers, followed by the sound of bodies falling to the ground and guns hitting the ground.

Several Mongolian soldiers who were napping were woken up, and they rubbed their eyes just to see what was going on, but several special forces soldiers who rushed in from the door wiped their throats with sharp daggers, and these Mongolian soldiers covered their throats with their hands and closed their eyes unwillingly.

The special forces used this method to quickly remove the obstacles in front of the army, and the army slowly followed the footsteps of the special forces, and the tanks had already stopped a long time from here.

Just when the Second Army was about a kilometer away from the Russian barracks, it was discovered by the Russian soldiers, and it was found that several Russian soldiers of the Second Army were running with guns to a small tribe in Outer Mongolia that had not moved in time to spoil the girl, and after eating, drinking, and having fun there, they rushed back to the troops, and when they passed by a sentry box, they found that the soldiers inside had been killed, and immediately fired their guns and shouted for an enemy attack.

Duan Qirui, who heard the gunshot, realized that he had been discovered, so he ordered the troops to attack directly, and he was already very satisfied with being able to touch it.

The Russian soldiers who were patrolling the barracks shouted for an enemy attack regardless of the sound of gunfire and the sound of the enemy attack, and the horn of the enemy attack continued to sound, and the Russian soldiers who were sleeping soundly in the barracks immediately jumped up and grabbed their guns, grabbed their guns, and ran out of the barracks before they could put on their clothes.

The Russian soldiers on patrol saw a large number of footsteps suddenly coming from the front and immediately opened fire on the front, and the Russian soldiers who had just run out from behind immediately ran up to help when they saw this situation.

"Bang~~~" "Bang~~~" "Bang~~~"

After a while, bullets were fired from the darkness ahead, some on the stakes of the barracks, some on the ground, and occasionally a few soldiers fell.

"Dada~~~"

The Russian soldiers hurriedly used several machine guns near the gate of the barracks, and they fired like crazy wherever the gunfire came, regardless of the enemy in front of them.

Under the suppression of the machine guns, the gunfire in the darkness in front of them weakened a lot, but soon the Russian soldiers noticed that a large number of gunfire was found from their left and right sides, and the soldiers behind hurriedly pressed back and fired back.

The sound of "boom~~~boom~~~" continued to sound, and a group of Tsarist soldiers and Outer Mongolian soldiers at the forefront were blown away, and those machine gunners were also killed.

It turned out to be a grenade thrown by the soldiers of the Second Army, and the soldiers of the Second Army were in the dark and the enemy was in the light.

Without the machine gunners, the 100,000 soldiers of the Second Army launched a large-scale attack on the Russian barracks, and the fierce attack caused the ill-prepared Russian soldiers to fall continuously, and the front trenches were quickly captured by the soldiers of the Second Army.

"General, withdraw quickly, otherwise our soldiers will be completely annihilated, the enemy's impact is too strong, we can't withstand it." Tsarist Russia's chief of staff in Serwusu persuaded Major General Lansley to speak.

"Damn, it must be the attack of the Huaxia Empire, are they declaring war on the Empire? He even launched a sneak attack like a despicable Japanese, undeclared war, and hurriedly sent a telegram to the headquarters asking for help. Listen to my order to retreat, retreat quickly, the logistics are not in charge, and the Third Army must not be buried in my hands. Major General Lansley shouted loudly.

Most of the Russian troops did not have time to get dressed, they were wearing thin vests and shorts, and they carried guns and shells and retreated in the direction of Kulen.

Due to the retreat of the army and the inadequate preparation, the Russian soldiers who were fighting with the Second Army were very passive and passive, and the rebels in Outer Mongolia fled frantically with the butt of the retreating army of Tsarist Russia, but there were still a large number of rebels in Outer Mongolia who were left by Tsarist Russia to fight with the Second Army.

Under the fierce offensive of the Second Army, a large number of Tsarist and Outer Mongolian soldiers were killed and wounded, but the brave Tsarist Russian troops shouted Ula and rushed to the guns of the Wehrmacht, and many Outer Mongolian and Tsarist Russian soldiers relied on the night and familiar terrain to launch a counterattack.

Duan Qirui, the retreat of the Tsarist Russian army, sent an army of 30,000 men to pursue, because the tanks did not play a big role in the dark night, and it was easy to lose their way and did not let the tanks track. The rest of the men were clearing out the Russian army and the Outer Mongolian rebels and counting the casualties, and now their task was basically completed, and they only had to wait quietly for the arrival of the other troops.

Sporadic battles continued, and it wasn't until the other two armies joined in the sweep that Selwusu was completely in control.

In this sneak attack, more than 20,000 enemies were killed and wounded, more than 10,000 people were captured, and only less than 30,000 of the enemy managed to escape, while the Second Army only suffered less than 5,000 casualties, but this casualty made Duan Qirui very dissatisfied, and it was already a lot for him.
