On the road east of Shangdu County along the eastern foot of Yinshan Mountain, Li Yunlong was leading his troops to advance eastward.

At the northern foot of Yin Mountain, the deep forest is dense under the mountain, and the army is very large and marches in concealment. Along the way, the team did not encounter the fighter air raid of the little devil!

It has been about twenty minutes since the withdrawal of Shangdu, and the army is not ten minutes away from the railway line from Ulan to Zhangjiakou!

"Order the troops to stop advancing and rest for five minutes! Let Sun Desheng come to me quickly! After Li Yunlong turned over and dismounted, he threw the reins in his hand on the horse's back, and then shouted to the herald.

The herald soldier commanded, "Yes, regimental commander. ”。

In less than half a minute, Sun Desheng, the commander of the cavalry battalion who was pressing behind the ranks of the army, rode his war horse to the place where Li Yunlong stopped.

I saw Sun Desheng turn over and dismount beautifully, and his movements were smooth, and Li Yunlong, who was watching, had to admit that Sun Desheng's riding skills were very good.

"Commander, are you looking for me? What's the mission? Hey, hey, hey! Sun Desheng walked up to Li Yunlong, saluted and said with a smile.

Li Yunlong patted Sun Desheng's shoulder and said with a smile: "Of course there is a task to find you kid!" Come, look at the map, here! ”。

"Pangnam Station? What do you mean, Captain? ”

Following Li Yunlong's finger pointing to a place on the unfolded map, Sun Desheng was a little puzzled.

Li Yunlong pointed to the map and said: "During the march, we have already contacted the local guerrillas of our army in Ulan and have made contact with them by radio. According to the telegram of the local guerrillas in Ulan, the Japanese army in Ulan was the 3rd Infantry Brigade of the 18th Infantry Wing of the 2nd Independent Brigade under the jurisdiction of the Devil Mengjiang Garrison Army. This devil infantry brigade has more than 1,000 people, and it seems that they have received an order from their superiors to send a squadron of devils from Ulan City to Pangnan Station! There will be a company of the Imperial Association Army at the station, and the puppet army will be stationed at the station for a total of more than 400 days! You take the cavalry battalion and attack the station first and see if you can take it down! It will take about ten minutes for the army to march to the station! ”。

"Guaranteed mission, Commander!" Sun Desheng's eyes lit up, is this a chance for the regiment commander to give the cavalry battalion a chance to eat some military exploits?

Li Yunlong said with a smile: "It depends on the situation when attacking!" Although it is said that it is not difficult for your cavalry battalion to hit a station, we are still unclear about the specific enemy deployment situation at the station, so we should pay attention and do not rush hard! ”。

"Understand, Commander, you can rest assured!"

Sun Desheng smiled and stood up.

Li Yunlong still waved his hand and smiled: "You kid, by the way, let Wang Chengzhu give you ten mortars, each mortar twenty shells, as artillery cover!" Take it with you! ”。

"Yes, Commander, I'll go right away!"

Sun Desheng said, then saluted and walked away.

Li Yunlong then sent people to summon Zhang Dabiao and others, and held another combat meeting on the way to rest and recuperate.

After Zhang Dabiao and the others gathered, Li Yunlong pointed to the spread map and said in a condensed voice: "According to intelligence, Matsui Shigen has ordered all the Japanese troops of the independent 2nd Brigade under the jurisdiction of the Mongolian Xinjiang Garrison Army in Chahar to be on alert, garrison these cities, and jointly defend them, and have established a preliminary blocking line in all cities in the northeastern part of Yinshan Mountain!" At present, a section of the railway line from Ulan to the foot of the northern foot of Yinshan Mountain has been guarded by the Japanese army along the way! Once we reach this section of the railway line, Matsui Ishine will basically determine our combat intention to maneuver towards the mountains in the northeastern part of Yinshan Mountain! Brothers, what do you think? ”。

"The soldiers will block the water and cover the earth, regimental commander! The railway line from Ulan to the foot of the northern foot of Yinshan is at least dozens of miles, and with the strength of Ulan's devils, he can only send troops to guard the middle of the Pangnan Station. As long as we take Pangnam Station, the devils of Ulan can't stop us! But I'm afraid that the devils at Miaotan Station in the direction of Yinshan South Road will go north for reinforcements! ”

Zhang Dabiao pointed to the map and analyzed that Miaotan Station is a station on a railway line southeast of Kangbao. If Kang Bao and Zhangbei's devils went north from Miaotan Station to reinforce the devil defenders at Pangnan Station, it would be a little uncomfortable to attack their own side for a long time.

With the railway as transportation, it is very easy for the devils in Chahar to reinforce the north.

The rest of the second battalion commander Shen Qun and others also nodded, and there was no way back at this time. If you go north, it is a large desert with few towns, which is not conducive to the supply of large armies along the way. The southward direction is the direction of Zhangjiakou, which is a big city where the devil's heavy troops are stationed, Li Yunlong did not dare to command the more than 7,000 people in the post to go south to attack Zhangbei, Zhangjiakou and other cities where the devil's heavy troops are stationed.

The army could only maneuver eastward, after all, there was still the threat of tens of thousands of heavy troops of the Japanese 3rd Division that Matsui Ishone was chasing.

"Okay, I've sent a cavalry battalion to set off first and attack the Pangnan Station! It should be relatively easy to take the station. But after passing through the station, we have two directions of action, one is to directly cross the Yin Mountain and exit the mountain, and then storm Baochang and go north to attack Duolun along the way. The other is to climb up along the lower edge of the northern foot of the mountain range in the northeastern part of Yinshan Mountain, enter Dalibo Lake and exit Yinshan in the east, attack the Jingshan, Linxi area, and kill into the Rehe River! The big guy is discussing and discussing, which direction to go? ”

As soon as Li Yunlong finished speaking, Zhang Dabiao and the others discussed with each other.

It stands to reason that Li Yunlong's first attack distance is the shortest, and he can quickly attack Baochang, Duolun and other places. What is a bit troublesome is that these two places are separated from Zhangbei by railroad to communicate with each other, once Baochang and Duolun are attacked by Li Yunlong and others, Zhangbei's devils will go north to reinforce very quickly.

And Baochang and Duolun are also heavily garrisoned by devils, and it is difficult to capture them in a short time.

What's more, when attacking Baochang, the devils of Duolun and Zhang Bei were bound to send reinforcements from the north and south, and at that time, the situation was still a bit dangerous for Li Yunlong and others.

The second attack route is relatively safe, and it can effectively lead the main force of the Japanese 3rd Division commanded by Matsui Ishine to continue to climb the mountains and wade through the water at the northern foot of Yinshan Mountain, dragging the 3rd Division commanded by Matsui Ishine to death!

Therefore, after discussing for a minute or two, Zhang Dabiao and others agreed with the second attack line!

"Good! Then take the second line of attack! The time has come, and the big guy directs the departments to continue the operation! Li Yunlong clapped his hands and said to everyone!

Everyone stood up and saluted, 'Yes, Commander! ’。

Li Yunlong led his troops to continue eastward and soon arrived at Pangnan Station.

The army rushed to the Pangnan Station, only to see that the Pangnan Station had been bombed into ruins, the station was actually not big, although there were more than 400 Japanese puppet troops fortified and defended.

However, Sun Desheng commanded the cavalry battalion to attack, but he still caught the enemy at Pangnan Station by surprise. In particular, there were only more than 200 Japanese troops at the station, and the rest were imperial allegorical troops, and their combat effectiveness was not strong. The cavalry battalion itself was as many as five or six hundred, and under one blow, the Japanese puppet army at the Pangnam station was quickly annihilated.
