As Ochiai Shizaburo began to give orders, Japanese artillery began to shell the north bank of the Arashi River, and at the same time a large number of Japanese troops began to force the crossing of the Arashi River.

The 1st Independent Regiment stationed on the north bank of the Arashi River was immediately engaged in the battle, and the artillery batteries of the two regiments immediately counterattacked.

After the commander of the 1st Independent Regiment launched an attack by the Japanese army, he immediately reported the news to Sun Weiguo.

After receiving the report from Regiment Commander Qian, Sun Weiguo dispatched the 1st and 3rd Battalions and the reconnaissance company directly under the regiment to set off, and these troops would quickly cross the Lan River and attack the Japanese troops from the flank.

At the same time, Sun Weiguo began to shrink the main force to Lanxian, and he wanted to take Lanxian as the center and fight a decisive battle with the Japanese army.

At one o'clock in the afternoon, the troops of the 1st Independent Regiment successively abandoned the river defense positions and withdrew the main forces to Lan County.

"Contact Yin Jin, Fu Tao, and Ge Haifeng, and ask their troops to hide and stand by after crossing the Lan River, and when all the Japanese troops cross the river, they will immediately set up a blocking position on the south bank of the Lan River."

"The Third Cavalry Regiment and the Sixth Cavalry Regiment are assembled on the west side of Lanxian County to hide and stand by, and wait until the city defense headquarters orders, Director Zhu, you will go to the cavalry unit of the Jinsui Army on behalf of me to supervise the battle, and anyone who escapes from the battle will be killed."

"The third battalion, the supplementary battalion will go to the position outside the city to fortify, prepare the artillery company of the first regiment, and the artillery company of the first independent regiment will immediately meet with the troops of the eighth artillery battalion to prepare the troops to garrison the county seat."

"The troops of the 1st Independent Regiment entered the county town and served as the city defense unit, and the armored company was quickly reorganized and trained, and together with the guard company, it served as the general reserve. The general order was given to all the divisions that once the Japanese troops crossed the Arashi River, they must be severely damaged. ”

When the troops of the 1st Independent Regiment began to withdraw, Sun Weiguo immediately began to issue combat orders, and he was preparing for a decisive battle with the Japanese army.

Even if he can't eat the Japanese troops, even if Sun Weiguo fights the troops this time, he will bring heavy losses to the Japanese army.

The garrison units began to mobilize, and unlike in the past, the Chinese troops did not stick to the north bank of the Lan River, but opened the road and directly let the Japanese troops go to Lan County to attack.

The Chinese troops got out of the way, and the Japanese troops could easily cross the Arashi River to the city of Lanxian.

However, the Chinese troops' approach made Shizaburo Ochiai become extremely cautious, and after learning the report of the front-line troops, Shizaburo Ochiai showed a solemn expression on his face, and the front-line troops were almost about to cross the Arashi River, but Shizaburo Ochiai ordered the troops to withdraw to the south bank.

"Chief of Staff, what's going on, why did you give the order to withdraw to the south bank, the Chinese army has been defeated, and we can now take the opportunity to go to Lan County to attack."

The acting captain of the 119th Wing, Shiro Miura, came to Shizaburo Ochiai, and he looked at Shizaburo Ochiai with a puzzled expression.

Knowing that the united flag he had returned was a forgery, Miura Shiro personally led the attack and saw that the Chinese troops were defeated, and his own troops were about to cross the Arashi River to attack Arashi Prefecture, but at this time he received an order from Ochiai Shizaburo to withdraw to the south bank.

"Have you seen the evacuation of the Chinese troops, according to the report of the front-line troops, the evacuation of the Chinese troops was not very panicked, they were evacuated in an orderly manner. Lan County Commander Sun Weiguo is treacherous and cunning, at this time, the Chinese troops will not intercept us in the Lan River and let us cross the Lan River, this is definitely Sun Weiguo's conspiracy. ”

Shizaburo Ochiai looked at Shiro Miura in front of him, and he said in a serious tone.

Hearing Ochiai Shizaburo's words, Miura Shiro recalled carefully, and he couldn't help but have a shocked expression on his face, he realized that the Chinese troops abandoned the river defense position, which was to attract his own troops to cross the Arashi River, which must have been a conspiracy.

"Immediately send a telegram to His Excellency the division commander to report on our situation here, at present we have no ability to defeat the Chinese army. If we continue to fight reluctantly, it is very likely that our troops will be severely damaged, or even completely annihilated. ”

Looking at the communication soldiers beside him, Shizaburo Ochiai had a solemn expression on his face, and he said solemnly.

The signal soldier did not dare to hesitate at all, and he immediately began to send a telegram to the regimental headquarters of the 109th Division.

Taiyuan City, the headquarters of the 109th Division, at this time, the division commander Shigehou Yamaoka was guarding the radio, and he hoped to get a report on the recapture of the wing flag.

"Your Excellency the Division Commander, the Chief of Staff is calling." The communications soldier had just received the message, and he immediately forwarded it to Shigetsu Yamaoka.

After taking the message and looking at it, Yamaoka's face became gloomy, his eyes flashed with a fierce light, and his face was full of angry expressions.

"Bagaya Road, all the troops in China are dead, and I want to break Sun Weiguo's body into ten thousand pieces." Yamaoka said in a cold tone.

The exchanged wing flags are fake, the real wing flags are still in Sun Weiguo's hands, but all the weapons and equipment exchanged by him have been taken away by Sun Weiguo, and what makes Yamaoka even more angry is that at present, his own troops have no ability to defeat and completely annihilate Sun Weiguo's troops.

"How many troops can be mobilized in our troops, I want to wipe out Sun Weiguo's troops, and I want to capture Sun Weiguo alive."

Looking at a staff officer of Nakasa, Yamaoka said in a cold tone, his eyes eager to burst into anger.

"Your Excellency the division commander, there are no troops in our division that can be mobilized at present." Staff Officer Nakasa immediately replied.

Yamaoka sat down in his chair in a daze, his eyes looking at the map with a somewhat helpless expression on his face.

"Send a telegram to the North China Front Command and request tactical guidance." Yamaoka said helplessly.

The 109th Division did not have any troops that could be mobilized, and Yamaoka Shigehou did not dare to take any rash action, he could only push the problem to the North China Front Command, and he hoped that the North China Front would send troops to solve Sun Weiguo's troops.

But where did Yamaoka Shigehou know, the North China Front Army had no troops to mobilize, and after Terauchi Shouichi received Yamaoka Shigema's telegram, he fell into silence, and after being silent for a long time, Snee began to give orders to the 109th Division.

On 12 March, the troops of the 109th Division attacking Lanxian County began to withdraw one after another, and the Chinese troops stationed in Lanxian County did not launch any pursuit.

On the same day, the first independent brigade of the Jin Sui army came to Lan County, with the arrival of the first independent brigade, the troops of the Jin Sui army in Lan County have exceeded two infantry regiments and two cavalry regiments, and the brigade commander of the first independent brigade is a major general, and the rank is higher than that of Sun Weiguo.

It was on this day that Sun Weiguo handed over the wing flag of the 119th Wing of the Japanese Army to Tang Chunhua, and at the same time gave the title of city defense commander to the major general brigade commander of the First Independent Brigade of the Jinsui Army.

"Brother Sun, don't worry, with our Jin Sui Army troops stationed in Lan County, I promise that no Japanese troops will cross Lan County and pose a threat to your Eighth Route Army troops, and I will say a few good words for you, Commander Yan."

Outside Lanxian County, Tang Chunhua held Sun Weiguo's right hand and said with a smile.

At this time, Sun Weiguo had already received a telegram from the commander of the 120th Division, and the first regiment immediately went to Lan County to rest and stand by.
