According to the operational plan drawn up by the expeditionary force, in order to consider that once our army's counteroffensive began, if the Japanese troops on the Burmese side attacked our Nu River with reinforcements along the Yunnan-Burma road, it was very likely that our Chinese army would endanger our army's flank and even shake our rear, so it was decided at that time to use the 20th Group Army as the attacking force to capture Tengchong, and the 11th Group Army as the defensive group army, to hold firmly along the river, and only a small number of troops of four reinforced regiments to cross the river and attack, so as to cope with the operation of the 20th Group Army.

Although at the time it seemed to be a very conservative battle plan. However, at present, the information on our crossing of the river has been leaked, and it is now necessary to redeploy the entire combat plan.

At present, the Japanese army has withdrawn from the defense line along the river, and most of the Japanese troops are defending the Tengchong area, if our army can change the war plan unexpectedly......

Judging from the current situation of the war, we are completely following the wishes of the Japanese army, so at present, our army should attack Matsuyama.

It's easy to say, if you attack Songshan, then the deployment of troops on the entire battlefield and the battle plan will have to be greatly adjusted accordingly, and this is also a kind of adventure in itself. The general offensive was blocked at the very beginning and suffered heavy losses. If the change of the battle plan at this time is further blocked, the Chongqing side will certainly make irresponsible remarks at that time.

This series of problems in front of the commander-in-chief and Yu Hanmin kept them awake all night.

However, as the commander-in-chief of the expeditionary force, his worries will not affect his determination.

General Headquarters of the Chinese Expeditionary Force.

"Ladies and gentlemen, the Japanese army's No. 1 battle plan in our territory is progressing smoothly, and there is a great tendency to bring down our Hunan and Guizhou and endanger our Yunnan and Guizhou. In order to reverse the crisis, we must quickly open up the situation on the battlefield in western Yunnan. The commander-in-chief asked, looking at the officers below.

"General seat, humble and incompetent, since the start of the battlefield in western Yunnan, our attack on Tengchong troops has been repeatedly blocked, and there have been heavy casualties. Some regiments even beat a dozen people left! ”

"Commander Gu, you don't have to blame yourself too much, the progress of Group B Army is not going well, and it is not your responsibility Commander Gu alone."

"The general seat, I believe that our army's attack posture must not be stopped, otherwise the Japanese army will press back at that time, and at that time, I am afraid that the story of Huitong Bridge will repeat itself."

"At that time, Kunming, Guiyang, Chongqing, and even the entire Asian theater will collapse because of the defeat on our Nu River." Yu Hanmin said.

"Commander Hu, tell everyone about the aerial reconnaissance situation."

"Yes, Chief!"

"According to the reconnaissance information provided by General Lai Anthra, there is no major movement of the Japanese troops covering Lashio in Mangshi at present."

"Ladies and gentlemen, the Japanese troops in Mangshi, Shafang, Lashio and other places have been slow to move, obviously waiting for the arrival of the Japanese army in Burma, so as to gather more reinforcements and want to form an encirclement and annihilation of our army in western Yunnan. It is clear that if the battle of western Yunnan cannot be quickly resolved, the enemy will form a stalemate. Then the situation will be more and more favorable for the Japanese army. ”

"Everyone also heard the analysis of Chief of General Staff Yu just now."

"How to fight the next battle, in fact, our ancestors have already told us."

"The water is controlled by the situation, the soldiers are defeated by the ground, and the one who can win because of the change is called the god. Then let's do this god today! ”

"The soldier is treacherous!"

"In addition to Tengchong, then we can make another heavy punch, take advantage of the opportunity of the devil to defend Tengchong's front line, transfer the new 28th Division to cross the river, and control Songshan ......, the barrier of the Yunnan-Burma Highway."

Matsuyama.

Matsuyama was centered on the sub-highlands, which the Japanese divided into four separate combat positions. They are Yin Mountaineering, Da Yakou, Rolling Dragon Slope and Changling Gang. These four positions were adequately water, electricity, ammunition, etc. The positions are densely lit and dark, and they can support and cooperate with each other. Among them, Yin Mountain, the Japanese army called the Pine Forest Position, which is the forward barrier in the south of the main peak of Songshan, defended by the 6th Infantry Squadron of the Japanese Army, and equipped with wing guns, light and dark forts, etc.

From a distance, the mountain looks like a large bell with a buckle on the top, and there is a slope of about 30 degrees at the top, which extends down to a steep slope of 60 or 70 degrees. The steep slopes are densely forested, and the trees on the gently sloping slope of the mountain top were cut down by the enemy yesterday, and the Japanese army was really thoughtful in thinking about building a fortress with these timbers and clearing the shooting boundary.

At the same time, there were several firing holes in the bunkers on the hill, which were faintly visible from the binoculars, and later attacking troops knew that these were camouflages to attract the fire of our troops......

"Your Excellency Commander, if the Chinese army wants to take Songshan, it will never be possible to cross Songshan without the corpses of 100,000 soldiers buried in the ravine."

"Jin Guangjun, I don't like you talking like this!"

"Even if the Chinese army uses 200,000 soldiers as a price, I don't want them to take Songshan."

"You must understand that Matsuyama's strategic position is very important to us, and you must not underestimate it. Today, the Chinese army on the other side of the Nu River has full American equipment and the cooperation of the US Air Force, while we have long lost air supremacy. ”

"Please rest assured that Your Excellency the Commander is fully prepared for battle, and even in the face of the bombing of the US Air Force, we have a way to deal with it, and we will never let them get any advantage......" said to Sakaguchi with confidence.

......

"Songshan, control the Yunnan-Burma Highway. The Japanese army occupying Songshan can be attacked, retreated and defended, and echoes each other with the devils of Longling and Tengchong. The Japanese army's 115 howitzer group in Songshan, a section of 100 kilometers on both sides of the Nu River, was all covered by its artillery fire. ”

"That is to say, if we take Songshan, we can seize the initiative, and our supply of food and ammunition can be unimpeded. And our heavily armed units can be directly engaged in combat through the Yunnan-Burma road. Yu Hanmin said.

"According to the information sent by our butterfly group, there are not many Japanese troops stationed in Longling, only one engineer wing, so I decided to take advantage of the fact that the main force of the Japanese army is concentrated on the right flank, and transfer the 28th Division to Songshan, Longling launched an attack on both sides with our superior forces, so that the enemy can not take care of each other......"

......

Some time ago in Mangshi, there was a small force of Chinese troops in the area, and Shimada would not let it go. At this time in these two places there was the appearance of Chinese troops.

Shimada wondered if the Chinese army would change its battle plan to attack Longling and Matsuyama. He had to report the situation to Commander Sakaguchi immediately......
