Back home, Feng Chen eagerly opened the letter that Keiko Hiraoka had written to him, Feng Chen didn't believe it, Ozaki Hidemi saw that he was just to deliver a letter from Keiko Hiraoka. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The envelope was opened, and sure enough, inside the letter written by Keiko Hiraoka, there were two blank pages of manuscript paper, Feng Chen took out the two blank manuscript papers, took out the potion from the bedside table, and smeared them on the manuscript paper for a while, and the handwriting on the manuscript paper immediately appeared.

Feng Chen couldn't wait to look at it, the first manuscript paper was the content of the meeting held by the senior Japanese generals in the consulate this afternoon, and the second manuscript paper was the next offensive plan of the Japanese army in North China.

The afternoon meeting of the senior generals of the Japanese army, in the midst of the noise, finally unified the caliber of the later Songhu operation:

1. Attack Dachang Town with 3 divisions.

2. The 11th Division entered the Yangjing line and maneuvered to cover its right side.

3. Take the 13th Division as the 2nd line, behind the right flank of the main force.

4. Attack Dachang Town with all your might, enter the line of Suzhou Creek, and advance to the south, the purpose of the attack is to enter the line of Suzhou Creek, eliminate the Chinese army north of Shanghai, block the southwest of Shanghai, and then attack Nanxiang.

After reading this information, Feng Chen then carefully looked at the next offensive plan of the Japanese army in North China.

1. After the Battle of Nankou, Tojo Hideki's column and the puppet Mongolian army broke through the defense fortifications between Yongjia Fort and Tianzhen defended by Li Fuying's troops along the Pingsui Line, and arrived at the foot of Yanggao Castle.

2. Li Bu fled all the way to the south of the Sanggan River, and Hideki Tojo planned to fully capture Datong on September 13.

3. The main force of the Japanese army in North China, the Itagaki Division, pointed to Pingxingguan, intending to copy the back road of Yanmen Pass, and then flank Taiyuan.

4. Yan Xishan's plan for the Battle of Datong has been leaked.

This information is too important, in Feng Chen's mind, the movement of the Itagaki Division, the main force of the Japanese army in North China, is what he is most concerned about, once the Itagaki Division captures Taiyuan, then the next step will directly threaten the central base area in northern Shaanxi.

At the same time, the reorganized Eighth Route Army was operating along the border between Shanxi and Shaanxi and was preparing to go to the front line in North China to resist the war.

Thinking of this, Feng Chen couldn't sleep anymore, got up and went downstairs, preparing to go to the Jinjiang Sichuan Restaurant on Aidoya Road, and try to immediately telegraph the information on the next move of the Japanese army in North China to the central government.

Feng Chen hurriedly came to the telecommunications room of the Jinjiang Sichuan Restaurant, Fang Xiaoman was not there, and Liu Geqing was sleeping on the bed in the duty room.

"Ge Qing, Xiaoman?" Feng Chen asked.

"I told her to go back and rest first, I'm on duty here." Liu Geqing sat up from the duty bed and replied.

"You're going to be on guard outside, and I'll send an important message." Feng Chen broke Liu Geqing away.

After Liu Geqing left the basement, Feng Chen immediately sat down in front of the radio station, put on headphones, adjusted the channel, and with excitement, began to call with the latest password given by Zhao Shouyi two days ago.

……

In a cave in Yangjialing, Yan'an, the telegraph operator received a call from the "cuttlefish", immediately translated the message, and went to the cave next door to report to the leaders who were at a meeting.

After listening to the contents of the message, the chiefs immediately studied the strategy of coping.

Since Japan launched a full-scale war of aggression against China, it has not suffered a single defeat, and at present, the Battle of Songhu is at a critical moment, and how to deal a heavy blow to the Japanese army in North China and boost the anti-Japanese fighting spirit of the people of the whole country is hotly discussed and studied in front of the map.

At dawn, everyone finally agreed on their opinions, and according to the direction of attack of the Japanese Itagaki Division in North China, they ordered the 115th Division of the Eighth Route Army to set up an ambush in the area of Pingxingguan to annihilate the invading Japanese army.

At the same time, the headquarters of the Eighth Route Army telegraphed to the friendly Second Army and the Sixth Army that the 115th Division of the Eighth Route Army was preparing to ambush the Japanese army in the area of Pingxingguan and requested the assistance of friendly forces.

After receiving a telegram from the headquarters of the Eighth Route Army, Yan Xishan asked the Eighth Route Army and the Gao Guizi Department of the Jin Sui Army to jointly defend Pingxing Pass.

Before the Japanese army reached Shahe, they resisted the Japanese army on the line of Lingqiu, Pingxingguan and Dayingzhen, and after the Japanese army entered Shahe, they concentrated 24 regiments of troops to fight a decisive battle with the enemy Japanese army.

At the same time, the Eighth Route Army was asked to attack the left flank of the Japanese attack during the decisive battle, and the deputy commander-in-chief of the Eighth Route Army agreed to Yan Xishan's request, saying that the Eighth Route Army would use a combination of movement warfare and guerrilla warfare to cooperate with friendly forces to encircle and annihilate the Japanese army.

The deputy commander-in-chief of the Eighth Route Army further said that the friendly forces held the front of Pingxingguan, and the 115th Division of the Eighth Route Army concealed and assembled on the flank of the Japanese army's advance road to flank the enemy attacking Pingxingguan from the flank and rear, and the 120th Division changed its original plan and went to the northwest of Shanxi Province to wait for the flank attack on the Japanese army attacking Yanmen Pass.

According to the route of the Japanese army's attack, Yan Xishan also formulated an operational plan on the 23rd, he appointed Fu Zuoyi as the commander-in-chief, with one division and two brigades as the general reserve, and with the strength of eight regiments, from the area north of the road outside the Inner Great Wall, to the east and west to run between the ponds and small villages, and flank the right back of the Japanese army.

Pingxingguan, located in Lingqiu County, Shanxi Province and Fanzhi County at the junction of the Guanling, is an important pass between the three passes and the outer three passes of the Great Wall in the Ming Dynasty, called the bottle-shaped stopper in the Song Dynasty, called Pingxingling in the Ming Dynasty, and began to be called Pingxingguan in the Qing Dynasty.

Pingxingguan is surrounded by mountains on all sides, peaks and peaks are stacked, and the terrain is extremely dangerous.

An ancient canyon road passes through the pass, reaches the Yanmen Pass in the west, and leads to the key place of Jingji in the east, which is a military pass since the Qin and Han dynasties, and is a place where soldiers must fight.

There have been many wars here in history.

Flat pass, the peaks and peaks on both sides are stacked, steep and precipitous, there are commanding heights such as East Running Pond and Lao Ye Temple on the left side, and the mountains such as Baiyatai are on the right side.

Pingxingguan mountain pass to Donghenan Town, Lingqiu County, is a narrow ditch that stretches from northeast to southwest, the most dangerous terrain is the middle section of the ditch, about ten miles long, the ditch is dozens of zhang deep, the channel at the bottom of the ditch can only pass a car, there are very few places that can be wrong, and the north and south ditch banks are relatively flat mountains, and it is the ideal place to ambush and annihilate the enemy.

After receiving the order from the headquarters of the Eighth Route Army, the leaders of the 115th Division made a preliminary plan at a meeting of cadres.

Everything was ready, and on September 24, the friendly 2nd Army and the 6th Army sent a plan to assist the 115th Division in attacking at Pingxingguan.

It was planned that the 71st Division would be attached to the new 2nd Division and the 1st Independent 8th Brigade to cooperate with the 115th Division to attack the Japanese army east of Pingxingguan.

The main force of the 115th Division was arranged on the edge of the mountain on the south side of the more than 10-mile-long highway from Pingxingguan to Donghenan Town.

The 686th Regiment of the 343rd Brigade is deployed near Baiyatai, with the 685th Regiment on the left and the 687th Regiment on the right, and at the bottom of the pocket is the 8th Independent Brigade of the 33rd Army of the friendly army, the 344th Brigade of the 115th Division, the 687th Regiment cuts off the enemy's retreat and fights to reinforce the enemy, and the 688th Regiment serves as a reserve.

This deployment made the enemy attacking Pingxingguan completely in an encirclement ambush.

At the same time, the Eighth Route Army set out from Guangou with a section and took the initiative to meet Guo Zongfen's attacking troops.

Before the battle, the troops of the 115th Division assembled in Ranzhuang.

On the evening of the 24th, the division commander gave the order for the brigades to attack:

The 343rd Brigade set off at 24 o'clock and entered the ambush position on the first line of Baiyatai, followed by the 344th Brigade, and at 24 o'clock at midnight, the troops marched on time.

For concealment, the troops chose difficult and rugged paths.

Not long after the departure of the 6868 regiment, the sky suddenly changed, the wind did not stop, the rain was like a pour, and the road was slippery in the dark, so the soldiers had a very difficult way to move.

In late autumn, the night on the Loess Plateau was already very cold, and the commanders and fighters were shivering from the cold.

After a period of heavy rain, a flash flood broke out, and the roar of the torrent blocked the way of the troops, and some of the soldiers who were eager to wade were swept away by the flood.

In order to reach the designated ambush site on time, the soldiers had to hang their guns and bullets around their necks, join hands to form a strong rope chain, and some pulled their horses' tails through the torrent formed by the torrent.

The flash flood was cold to the bone, and the legs of the cadres and soldiers were numb.

On the same day, the 115th Independent Regiment of the Division arrived at the waist station between Lingqiu and Laiyuan, and fought a small encounter .......

Before dawn on the 25th, the 685th, 686th, and 687th regiments of the 11th Division all entered the ambush position.

The team hid in a ravine on the south side of the road, the sky was still gloomy, the cold wind was blowing, they were afraid of exposure, and they were not allowed to light a fire, so the soldiers could only grit their teeth and endure it, and let the boiling blood dry their wet clothes.

At the same time, the 1st Division of the 344th Brigade covertly entered a high ground north of Donghenan Town, and in order to facilitate observation and command, the division command post was set up on the hill southeast of the ditch.

The cadres and soldiers of the 115th Division made all preparations for combat.
