The 11th War Zone drew about 30,000 troops and attacked various towns along the Middle East Railway within three days. Some of them had feinted attacks and some were real attacks. For a time, wars and alarms were frequently heard along the railway.

The "Chinese" army came out! Almost all the alarms contained such a sentence, which surprised Ananwei. However, after careful consideration, he vaguely felt that it was no big deal. In his mind, there was no concept of the Chinese team taking the initiative to attack and provoking large-scale battles. The imperial army always took the initiative to chase and suppress the bandit army. When did the Chinese actually have the courage to launch an attack?

Anan Weiji was more willing to imagine this behavior as a raid war similar to the "Hundred Regiments War". He did not believe that Ma Zhanshan or the Anti-Japanese United Nations conquered Manzhouli and Hailar. He believed that his front-line troops would soon repel the "harassing" Zhongzhao team, so Anan Weiji did not act rashly. It was not a joke to dispatch the large army and it would take a lot of logistics and energy. If nothing could be caught after being dispatched, the labor force would be exhausted and the people would be injured and the money would be costly.

Two days later, the situation became worse and worse. Anan Weiji's front-line troops were defeated one after another, losing the strategic key points of blocking the Chinese resistance army in the mountains. An unknown number of Anti-Japanese United Army surged out of the mountain pass and appeared in Hadatu, 30 kilometers away from Hailar.

Until this time, Anan Weiji didn't believe that the army was coming for Hailar. He hurriedly ordered two brigades of the 14th Division nearby to fight against this bold anti-Japanese unit.

That night, the two brigades of Japanese troops disappeared into the bloody mouth of the Anti-Japanese Allied Forces. According to the return of the Japanese army who fled back, they encountered an old opponent of the Tenth Anti-Japanese Allied Forces, which was at least five times the number of people, and had a large number of artillery and chariots. Their firepower was hard for the Japanese army to stand against.

Anan Weiji was then moved. However, before he could fully refine the intentions of the Anti-Japanese Allied Forces, he received an emergency telephone line from the Eighth Border Guard stationed in Hailar. He was in trouble and asked for reinforcements.

The Eighth Border Guard has a huge organization and is almost a brigade when it is full. However, in the winter attack battle, the garrison has also drawn personnel to attack the mountainous areas. After the loss of troops and generals, it has not yet been replenished. Now there are only 3,000 combat soldiers. Facing the 10th Anti-Japanese United Detachment carrying a large number of heavy equipment, I feel guilty and forced to call Anan Weiji to send troops to support.

After a nearly completely wiped out breakout battle, there were about 500 surviving cadres and soldiers. After the soldiers who were secretly nourished and recovered from wounds in various places, all the veterans had only 800. Out of the consideration of protecting this heroic force, when the remnants retreated into the Erguna base, they never participated in the battle again.

During this period, the Tenth Detachment successively accepted new recruits. When a group of new recruits based on Henan victims entered the Tenth Detachment camp, the scale of the Tenth Detachment expanded unprecedentedly, reaching 10,000 people a month ago, becoming a division-level detachment.

The veterans of the 10th detachment were still there, and their fighting spirits remained. They quickly washed away their sadness and rejuvenated their youth after replenishing the large number of new recruits. Although the average quality of individual soldiers decreased, due to the greatly enhanced number of people and heavy weapons, the overall combat effectiveness was actually improved.

Before dawn, the Tenth Detachment arrived around the fortress. Before setting up an offensive position, it was subjected to a tentative attack by the eighth Japanese garrison. The Tenth Detachment had only launched a regiment. With the cooperation of six German Type 4 tanks that rushed to the battlefield, they defeated the two squadrons of the attack with a storm-like artillery fire. Most of the Japanese troops were forced to shrink into the fortress to prepare to hold on.

There was a chaos in Hailar city, and Japanese and puppet institutions fled to the fortress group one after another. Most of the people fled with their children and daughters outside the city. The Anti-Japanese Allied Forces did not intercept them and allowed the people in the city to evacuate them.

The airport was already sneak attacked by the first battalion of the special forces led by Yang Hong an hour ago. More than a dozen reconnaissance planes that had not yet taken off, bombers and fighters were destroyed on the ground, and thick smoke is still rising above the airport.

The fortress project started in June 1934 and was completed at the end of 1937. It covers an area of ​​21 square kilometers. The fortress, the Obao Mountain position, the Itotai position, the Henan Taiwan position, the Nansongshan position, the Southeast Mountain position, etc., constitute a strict Hailar military defense main body. In the entire system, military fortifications composed of the North Mountain and the Obao Mountain formation are the top priority.

The above-ground and underground fortifications in the Beishan position are very complex, large in scale, and complete in various facilities. They belong to the command center of the Hailar Defense Zone and are called the "underground city".

In order to build this fortress, the Japanese forced tens of thousands of Chinese workers and killed the workers after the completion. One of the concentrated burial sites was between Beishan and Aobao Mountain. Thousands of remains were found there after the war.

Ma Qian'an was not interested in attacking four positions, including the Itotai position, Henan position, Nansongshan position, and Southeast Mountain position, which had no underground fortifications. According to the latest reconnaissance information, there were only less than 500 defenders who fled in a hurry on these positions. They could not get enough waves and ordered a small number of soldiers and artillery to monitor or feint attack, so that they could not make trouble. It would not be too late to take down Beishan and Aobao Mountain before they were defeated.

Ma Qian'an had only one day to attack without interference. He had received a notice from the Guo army or the Anti-Japanese United Army units responsible for blocking the enemy's reinforcements. The blocking force had entered the blocking position and could provide him with a maximum of two days and at least one day of attack time, so that he would not have to worry about the enemy reinforcements packing his dumplings.

Ma Qian'an established a command center about one kilometer northeast of Beishan Fortress. This place can also monitor the Aobao Mountain Fortress, which is also one kilometer away from the Aobao Mountain Fortress.

The preparations of each branch were summarized one after another in Ma Qian'an's command center.

"Report that the first, second and third battalions of the artillery regiment have been deployed according to the preset positions, and the shells have been loaded and waiting for orders."

"Report that the first battalion of the Tank Regiment has occupied the starting position and is ready to attack at any time."

"Reported, the headquarters call, the air force base has taken off six p40 aircraft, two p38 aircraft, and two b25 aircraft, and two b25 aircraft are expected to arrive over the battlefield in 20 minutes."

On the position, eight newly formed artillery groups raised their barrels, and the gray cannon body shone with cold light. This is the Soviet-made e2 76.2mm caliber mountain cannon. It is an excellent artillery with a range of up to ten kilometers. However, in order to pursue accurate shooting, the artillery mostly deployed the cannons 34 kilometers away from the fortress.

Li Fengshan, the captain of the 10th Detachment, was enthusiastically fiddling with an oxygen mask. This kind of thing was issued a few days ago and was configured for the rocket soldiers who fired cloud bombs. After attacking the tunnel, the cloud bomb explosion will burn out all the oxygen. Rocket soldiers can't do without it.

Ma Qian'an stood in front of the map and thought quietly for a while. Then he gave a few brief instructions to the staff officer beside him. He was not relaxed when the war came. He accidentally saw Li Fengshan fiddling with the oxygen tank and turned on the switch from time to time to take a snatch, and couldn't help but laugh and cry.

"Hey, how old are you still playing like a child? I remember you were in charge of commando commands and the attack was immediately started. Are you ready? Be careful that our military law is engaged in you!"

With Ma Qian'an here, Li Fengshan basically lost his overall command. Many times, his position was more like a setter, giving Ma Qian'an's orders to his subordinates, and Ma Qian'an also prevented him from receiving actual tasks and letting him follow him to learn command, which made him a little unhappy.

When Li Fengshan heard this, he rolled his big eyes and wanted to say something. He suddenly saw the group leader Ding Lianhuai who was rushing to come. He immediately passed on Ma Qian'an's words. He shouted to Ding Lianhuai: "Hey, I said, I remember that you were the commander of the commando. When the war was about to start, he ran to the headquarters? Are you ready? Be careful that I will kill you!"
