In Dongma Town, Ningwu County, Sun Weiguo has returned to the temporary headquarters here.

Zhu Jianwei, chief of staff of the Unknown Regiment, Liu Ke, chief of staff of the Honorary Fourth Regiment, and Chen Yang, chief of staff of the Honorary Fifth Regiment, also came here, and they reported to Sun Weiguo on the operational situation of each unit.

The main force of the 2nd Independent Mixed Brigade of the Japanese Army has been completely annihilated, except for a few Japanese troops who have fled in hiding, the 2nd Independent Mixed Brigade has basically been completely annihilated.

After Sun Weiguo learned about these situations, he looked at the map, Wang Kunyao Intelligence Section had already sent a message, a large number of Japanese troops were moving closer here, Sun Weiguo knew that he had to make a decision quickly, otherwise the troops of the Honorary Second Division were likely to be divided into two by the Japanese troops.

"Division commander, there is still a chance for all the troops to withdraw to Wutai County now, and it will still take time for the Japanese troops to arrive here." Deputy Chief of Staff Sun Ziyuan came to Sun Weiguo and reported softly.

Sun Weiguo stared at the map, and when he heard Sun Ziyuan's words, he nodded, with a contemplative expression on his face.

Naturally, there was time for the various departments of Ningwu County to withdraw to Wutai County, but Sun Weiguo did not want to withdraw all the troops to Wutai County now.

Although according to the battle plan, the 120th Division and the troops of the Shanxi-Chahar-Hebei Military Region would fight in the periphery in response to the troops of the Honorary Second Division, Sun Weiguo was somewhat hesitant in his heart.

The 120th Division and the troops of the Shanxi-Chahar-Hebei Military Region lacked mobility, and once the Honorary Second Division of Wutai County encountered a crisis, it would be difficult for these two units to arrive.

Moreover, their operations are to be carried out around their respective stations, which will have some impact on the next operations.

Sun Weiguo planned to leave a unit to fight in the periphery of the Honor Second Division, but which unit to leave behind made Sun Weiguo a little embarrassed.

It is naturally best for Yin Jinshan's Honorary Fourth Regiment to stay on the periphery, but the Honorary Fourth Regiment is an armored unit, and their target is too large, and once they disperse their actions, it will inevitably weaken the combat effectiveness of the troops, and the tank needs fuel, and many nearby terrains are not suitable for tanks.

"Chen Yang, your honor of the fifth regiment stayed, your troops are fighting on the periphery, at present, the main forces of the Japanese army are all coming to the front line, their rear is empty, you concentrate your forces to fight the Japanese baggage troops, contain the Japanese troops, and cooperate with the main force of the division to fight."

After hesitating for a while, Sun Weiguo looked at Chen Yang, chief of staff of the Honorary Fifth Regiment, and said with a serious expression.

"Yes, Commander." Chen Yang didn't hesitate, he saluted Sun Weiguo and agreed.

At eleven o'clock in the evening, the Honorary Fourth Regiment, the Unknown Regiment, the Combat Engineer Battalion and other troops began to withdraw to Wutai County, while Ge Haifeng's Honorary Fifth Regiment was left on the periphery by Sun Weiguo.

At one o'clock in the morning of September 20, 1938, the troops of the 1st Division, the 21st Division, and the 114th Division entered Ningwu County, the independent garrison and the 3rd Independent Mixed Brigade entered Mengxian, and the troops of the 109th Division and the 26th Division were still fighting against the 120th Division in Dai County.

At this time, the 110th Division of the Japanese Army and the troops of the Fourth Brigade of the Independent Mixed Brigade fought with the troops of the Shanxi-Chahar-Hebei Military Region in Yixian and Quyang counties respectively.

At 3 o'clock in the morning of 20 September, the North China Front Army made adjustments again according to the situation of various departments, the troops of the 1st Division entered Yuanping County and attacked Wutai County from east to west, the 26th Division and the 109th Division attacked and advanced from Dai County, and attacked Wutai County from north to south, the troops of the 21st Division and the 114th Division entered Meng County, and after entering Meng County, the 114th Division was equipped with an independent garrison to attack Wutai County from south to north, and the 21st Division was equipped with independent mixed 3rd Brigade troops to enter Pingshan County through Meng County. They will launch an attack on Fuping County from Pingshan County and cooperate with the 110th Division.

The Japanese troops began to deploy troops, and they put five divisions and two independent brigades and one independent garrison into operation at one time.

The news of the total annihilation of the 2nd Independent Mixed Brigade was completely blocked by the top brass of the North China Front, and the troops participating in the war did not know about it at all.

The Japanese troops were actively making deployments, and the troops of the Eighth Route Army were also beginning to make detailed deployments.

The troops of the 120th Division began to enter Dai County and Yuanping County respectively, and the troops of the Shanxi-Chahar-Hebei Military Region were under greater pressure, and they had to defend Mengxian, Fuping County, Laiyuan County and other county towns respectively, but fortunately, the 120th Division and the troops of the Shanxi-Chahar-Hebei Military Region were mainly to delay the attack speed of the Japanese army and contain and consume the physical strength of the Japanese army, and they were not blindly fighting positional warfare.

The county seat of Wutai County, the headquarters of the Honorary Second Division.

It was already more than three o'clock in the morning when Sun Weiguo rushed back here, and after coming to the county seat of Wutai County, Sun Weiguo immediately began to deploy the troops of the Honorary Second Division.

At present, the main force of the Honorary Second Division has not suffered any losses, in addition to the Honorary Fifth Regiment deployed on the periphery, Sun Weiguo also has in his hands the Honorary First Regiment, the Honorary Second Regiment, the Unknown Regiment, the Honorary Fourth Regiment, the Honorary Sixth Regiment, and eight battalions directly under the division headquarters: the special service battalion, the reconnaissance battalion, the guard battalion, the engineer battalion, the baggage battalion, the combat defense artillery battalion, the supplementary battalion, and the communications battalion.

In addition to the five regiments and eight battalions of the Honor Second Division, Sun Weiguo also had the fifth detachment of the 120 Division and the four county brigades of the Shanxi-Chahar-Hebei Military Region, and now Sun Weiguo has more than 23,000 troops.

As for how these troops should defend Wutai County, Sun Weiguo had a debate with Chief of Staff Zhao Lerong.

According to Zhao Lerong's suggestion, the troops of the Honorary Second Division should stick to every inch of land, use their advantages in fighting defensive warfare, and fight for every inch of land with little devils, so that every part of Wutai County will become a battlefield.

Sun Weiguo's view is different from that of Zhao Lerong, Sun Weiguo intends to abandon the past first-line defense, and he wants to change the name to key defense.

"Division commander, now there are little devils near Wutai County, if we carry out a key defense, there will be a lot of gaps, and the little devils can use these gaps to break us down." Zhao Lerong pointed to the ghost soldiers marked on the county seat near Wutai County, and he said with a solemn face.

"Chief of Staff, don't forget, we have an armored regiment and two mechanized battalion-level troops in our hands, and there are a small number of armored units in both the engineer battalion and the supplementary battalion, as long as the little devils dare to infiltrate through these gaps, we can use these mobile troops to quickly defeat or even completely annihilate them."

Sun Weiguo said with a smile, he had already considered these problems.

"Weiguo, how do you plan to deploy the troops, although we have a lot of troops now, but after all, our troops have just been expanded, and the fifth detachment of the 120th Division and the four county brigades of the Shanxi-Chahar-Hebei Military Region, they rarely engage in positional warfare, and rashly let them fight positional warfare, I'm afraid they will be unbearable."

Political commissar Shen Wei also came to Sun Weiguo at this time, she looked at Sun Weiguo, and said in a worried tone.
