After recovering Shenyang, the Eighth Route Army and the 100,000 elite troops of the Longya Corps joined forces and marched north along the South Manchurian Railway, and encountered the main force of the Kwantung Army that reinforced more than 100,000 troops from Changchun, Harbin and other places in North Manchuria, and started a fierce battle.

After capturing Shenyang, Qiao Youhua immediately instructed the logistics department and the engineering unit to mobilize the local people to repair the railways, highways, and bridges damaged by the Japanese army, and repair the Shenyang airport as quickly as possible.

This allowed the Falcon Flying Regiment of the Dragon's Tooth Corps to be stationed in the Shenyang area, bringing the entire South and North Manchuria into the range of its air fire.

At the same time, Qiao Youhua completely and cleanly wiped out the Kwantung Army that had gathered in North Manchuria and the Sino-Soviet border, and urgently ordered Ma Biao to command three newly organized infantry divisions and some tanks, armor and artillery units, totaling more than 100,000 people, to quickly go out of the customs to participate in the battle, so as to make up for the disadvantage of the lack of combat troops in the first batch of customs.

This 100,000-strong army was expanded from Ma Biao's Second Division, and it was the elite unit of the whole army second only to Jiang Haidong's department.

In addition, the head of the headquarters of the Eighth Route Army also urgently transferred 50,000 guerrillas from the anti-Japanese base areas such as Jinsui Chameng to enter Liao from Rehe to support the campaign outside the Guan.

In the Battle of Siping, the strength of the Longya Corps and the Eighth Route Army was more than double that of the Japanese army, and the Falcon Flying Regiment provided timely air fire support, which was well-equipped and the armored force had strong assault firepower, so by the time the Japanese follow-up reinforcements arrived in Changchun, the Longya Corps and the Eighth Route Army had defeated the Siping Japanese army and captured the Siping station and the urban area.

More than 100,000 Kwantung troops were killed and wounded, and the rest of the army retreated to Changchun and other northern Manchurian areas. The Dragon's Tooth Corps and the Eighth Route Army jointly pursued, and the Japanese soldiers killed were defeated like a mountain and collapsed.

At this time, 150,000 follow-up reinforcements also entered the customs from two directions, especially Ma Biao's 100,000 elites, thanks to the logistics office and the people outside the customs to repair the railway, highways, bridges from Nanman to Shenyang and other places were all unblocked within a few days.

Ma Biao's troops were able to reach Shenyang in the shortest possible time, and then followed the front-line troops under the command of Liu Yidao to advance towards Northern Manchuria. The 50,000 guerrillas of the Eighth Route Army from Rehe also rushed to the Shenyang area with tenacious will and speed.

It is worth mentioning that they arrived at their designated destination only one day slower than the reinforcements of the Dragon's Tooth Corps, which had complete logistical support and were fully mechanized on the march.

So far, the total strength of the Dragon Tooth Corps and the Eighth Route Army outside the pass has exceeded 350,000.

The Japanese Kwantung Army, after the Battle of Western Liao, the Battle of Jinzhou, the Battle of Shenyang, and the Battle of Siping, has lost more than 200,000 people.

In addition, the Kwantung Army in Dandong and other places withdrew into the Korea, Xian, and Peninsula without authorization due to the disappearance of the commander Hideki Tojo, so the total strength of the Kwantung Army at this time had lost more than half.

Historically, the total strength of the Kwantung Army at its peak had reached more than 800,000, known as one million.

During this period, due to the changes in the situation in the Guannai and the strong rise of the Dragon's Tooth Corps, the strength of the Kwantung Army was always only maintained at about five or six hundred thousand.

After the Battle of Nomenkan, the Japanese Kwantung Army was severely taught a lesson by the Soviet Red Army, losing 10,000 people, not to mention the fact that it also focused its defense on the border with the Soviet Union.

Therefore, before the Dragon's Tooth Corps went out to fight, the Kwantung Army deployed more than 300,000 troops on the Sino-Soviet border to guard against the Soviet Red Army.

At first glance, the strength of the Kwantung Army was 560,000, plus hundreds of thousands of puppet Manchukuo puppet troops, the total strength exceeded 1 million, which was 10 times that of the Longya Corps.

In fact, there were less than 100,000 Japanese troops who really fought with the Eighth Route Army and the Dragon's Tooth Corps, because hundreds of thousands of Kwantung Army and hundreds of thousands of puppet troops were scattered and stationed in the northeast, which is more than 1.5 million square kilometers.

Therefore, at the beginning, only the Japanese army deployed in Shanhaiguan, the western Liaoning corridor to Jinzhou, and the hundreds of thousands of Japanese troops in the southern Liaoning area, plus more than 100,000 puppet troops.

With the well-equipped and rich combat experience of the Dragon's Tooth Corps, and the fact that it had seized air supremacy in advance, it was naturally not an accident that it won the Battle of Liaoxi.

You must know that since Qiao Youhua created the Dragon Tooth Column in 37 years, today's Dragon Tooth Corps has been fighting almost all the time, and all the officers and soldiers have grown up from battle after battle, and have been baptized by war.

In recent years, the Japanese Kwantung Army has hardly fought any decent battles except for the Battle of Nomenkan, and its experience in fighting in the Dragon's Tooth Column is even inferior to that of the Japanese puppet army in East China and North China.

In the Battle of Nomenkan, the nightmare caused by the torrent of Soviet armor to the Japanese army is still there, and it seriously affects the morale and morale of the Japanese Kwantung Army.

In the battle with the armored forces of the Dragon's Tooth Corps, it is inevitable that it will be affected.

Therefore, the reason why we were able to win quickly in this out-of-customs operation seems to be accidental, but in fact it is inevitable.

Qiao Youhua judged the situation and decisively went out of the customs to march into the northeast, to the surprise of many people, and the Japanese army did not expect that Qiao Youhua would go north at this time, after all, compared to the situation in Jiangnan, South China and the Central Plains.

Fighting north looks a little more difficult for the Dragon's Tooth Corps.

The Kwantung Army is the only heavily armed group in the Japanese army that has invaded China and has not suffered a major blow.

It was precisely because of this that the Kwantung Army was caught off guard by the Dragon Tooth Corps and the Eighth Route Army, and in less than a month, it suffered successive defeats, defeated, and collapsed.

After the reinforcements were in place, Qiao Youhua was appointed by the Eighth Route Army Headquarters as the commander-in-chief of operations outside the Guan, responsible for commanding the Longya Corps and all the troops of the Eighth Route Army outside the country.

After Qiao Youhua obtained the unified command, he immediately ordered Ma Biao to lead 100,000 elite and 50,000 guerrillas of the Eighth Route Army to advance to Changchun, preparing to join Liu Yidao and other troops to besiege Changchun.

At this time, Changchun was the puppet capital of the puppet regime of the puppet state of Manchukuo, and was called Xinjing.

After the defeat of the Japanese puppet army in the Battle of Siping, the emperor of the puppet Manchukuo, Pu Yi, could not sleep well, if it were not for the Japanese not allowed, he would have abandoned the city and fled.

The Japanese army now needs him to sit in Xinjing to stabilize the hearts of the people and the army, otherwise the puppet Manchurian **** will instantly become a plate of scattered sand and flee in all directions.

The Kwantung Army has been operating in Changchun and other places for a long time, and there are more than 100,000 puppet troops as its wings, plus more than 100,000 Japanese troops are coming from all over the North Manchurian border, trying to fight a decisive battle with the Dragon Tooth Corps and the Eighth Route Army here.

If the North Manchurian is controlled, the Kwantung Army will still have a foothold, otherwise there will be no need for the Kwantung Army to exist.
