At the headquarters of the Eighth Route Army in Ruijin, Jiangxi, Runzhi and Zhu De were deeply surprised after reading Lin's handwritten letter. Runzhidao: "The situation is gratifying and pressing, Lao Jiang is taking advantage of the situation." In order to gain political capital after the war, and the timing was just right. The return of Outer Mongolia is the will of the whole nation, and since Lao Jiang took the lead, there is no reason why we should not support it. "Chairman, once the Japanese learn that they have sent troops to Outer Mongolia, it will inevitably affect the situation in the Beijing-Tianjin war?" Zhu De was a little worried.

"I couldn't say for sure what would happen next, so I had to wait and see. I have already repaired a book, asked someone to bring it back to General Fu Zuoyi, and agreed to send troops to Outer Mongolia. "Chief of General Staff Ouyang called and agreed. He believes that Outer Mongolia has been Chinese territory since ancient times, and there is no need to look ahead and backward. "Do you want the forest department to start preparing?" "Don't worry, the time is not ripe for the forest department to enter Outer Mongolia, let's play the game of chess in Beijing and Tianjin first."

In early June, the office of Stalin in the Moscow Kremlin. An official of the Soviet Russian Ministry of Defense reported in a panic: "Comrade Stalin, I have just received a report from the Mongolian side that the Mongolian border guards have found that two cavalry divisions of the Chinese army have forcibly entered Mongolia on the southwestern border, and the Mongolian border guards are powerless to block the entry, and they have judged that the target of the Chinese cavalry unit is Uriya Sutai. ”

Stalin said with a calm expression: "The time has finally come, the Chinese government has chosen the right time, and we are powerless to stop it at the moment." The war has led to the rapid rise of China's military power, and the Mongolian problem must be solved by military means, but there is nothing we can do about it now. Since the Chinese army chose to enter secretly, we also pretended not to know. Time, we need time, notify the intelligence services, and use another channel to leak the information to the Japanese. ”

Stalin explained: "The Japanese understood the situation in Outer Mongolia and would certainly take corresponding countermeasures. If we can win half a year, we will create conditions for us to transfer troops to the east and solve the Mongolian issue by military means. It is also time for the Mongolian issue to be completely resolved, and the justification for a military strike is valid, and the Chinese Government must not be allowed to take back Mongolia. In addition, he told Baqiaoshan to be patient and not impulsive. ”

A few days later, the Japanese intelligence headquarters received accurate information about the Chinese army's entry into Mongolia from the Soviet Russian Far East intelligence. The Japanese army headquarters immediately held a meeting, and it was agreed that this was a golden opportunity, that the importance of Mongolia to Soviet Russia was undoubted, and that if it could provoke hostility between China and the Soviet Union, it would be good news for the crumbling Japanese Empire. To this end, Hideki Tojo ordered Okamura Ninji to quickly change the defense plan for the Beijing-Tianjin area, and at the same time, strengthen the defense on the front line in Manchuria.

At the headquarters of the Chinese Dispatch Army on the day of the brigade, Gangmura Ninji said to the chief of staff: "According to the order of the base camp, the Beijing-Tianjin defense line should be adjusted on a large scale. The base camp believed that the formation of a new defense line around the Bohai Bay in Tianjin and Tangshan would create conditions for Soviet Russia to intervene militarily in Mongolia. At present, the Chinese side is still carrying out an overall offensive posture, and we must quickly withdraw the troops on the first line of Beiping before the enemy notices it, and form a new and solid defensive line relying on Tianjin and Tangshan. ”

"Ordered the 46th Division and the 107th Division of the Jinan Front Line to quickly retreat to Tianjin, and ordered the Zhangjiakou, Baoding, and Cangzhou front-line troops to retreat to Beiping, and the defenders of Beiping successively retreated to the Tangshan line. He ordered Ban Heng to seize Shiro to rush to transport military supplies from Beiping as soon as possible, and not a single shot or bullet or grain could be left for the enemy. The enemy army on the southern front is preparing to launch an attack on Jinan, and I will let the enemy's attempt fail, and buy a month to prepare. If a war between China and the Soviet Union could be provoked, the Japanese Empire would hold on to the Northeast, the Northeast and the Korean Peninsula would be stable, and the Mainland would have peace of mind. ”

In late June, Fu Zuoyi's military operation into Outer Mongolia went very smoothly, and the Soviet and Russian sides reacted coldly. However, the headquarters of the Eighth Route Army and the headquarters of the Nationalist Government were not aware of the changes in the Japanese army. The Japanese army took advantage of the cover of darkness and first withdrew half of its troops in Jinan, and the Japanese army successfully deceived the puppet army in order to keep it secret. Subsequently, the Japanese army also began to secretly withdraw troops on the Zhangjiakou line, Baoding line, and Cangzhou line.

On this day, at the headquarters of the 1st Corps of the Eighth Route Army in Xuzhou, Corps Commander Su Yu was reporting to Peng Dehuai: "General Peng, according to the deployment of the campaign, the Independent Airborne Division has assembled at the Xuzhou Military Airport. The Zhao Liang Division of the 1st Army, which is interspersed with our corps, has been waiting for an opportunity to go north at any time, and the 2nd, 3rd, 4th, and 5th Field Armies are ready to advance head-on. The newly formed 18th Army, the 22nd Army, and the Shandong Independent Column are ready to encircle Jinan. ”

Peng Dehuai nodded and said: "According to the deployment of the headquarters, after encircling Jinan, your First Army will immediately go north, outflank the northwest of Tianjin, block the Japanese army's northward escape route, and the independent airborne division will seize Tanggu and block the Japanese army's escape route at sea. This battle is very crucial, and it is necessary to eat the three divisions of the Japanese army in Tianjin. "Report, Dark Arrow Urgent Notification!" An operational staff officer reports.

Su Yu took the telegram and checked his face and said: "Mr. Peng, this morning, the dark arrow intelligence officers found that the puppet army in Jinan City fled frantically to the north and did not find the Japanese troops. Peng Dehuai took the telegram and asked in surprise: "Is the news accurate?" "Order the 22nd Army to immediately dispatch a regiment to advance to Jinan!" Keep in touch with Darkarrow, and I'll hear a detailed debriefing in an hour. ”

After the initial shock subsided, Su Yu said: "Mr. Peng, is it difficult that Okamura Ningji discovered our attempt to stick to Beiping and Tianjin?" Peng Dehuai was speechless, if the Japanese army reduced its forces and stuck to Beiping and Tianjin, all previous efforts would be in vain. An hour later, news came from Jinan again that it had become an empty city. Peng Dehuai said with a blushing face: "Our intelligence department is a dry meal, and we don't even know about such a major change. ”

Su Yu blamed himself: "Mr. Peng, blame me for being careless, I was negligent!" "Suspend all military operations, and I'll go back to headquarters immediately!" After Peng Dehuai finished speaking, he immediately rushed to the military airport. At Ruijin Airport, the two transport planes landed almost front and back, and after the plane stopped, Peng Dehuai and Ouyang Jian stepped off the plane together. "Brother Ouyang, do you know the situation!" "Got it!" The two got into the jeep.

In the car, Ouyang Jian said: "Okamura Ningji, this old fox is too cunning, the two divisions of the Japanese army retreated to Tianjin, and our plan fell through." If the Japanese army sticks to Beiping and Tianjin, we cannot use heavy weapons in Beiping, and the Japanese army will take advantage of this, which will inevitably cause huge casualties to our troops. "In the end, we can only make this decision, surround Beiping, encircle but not fight, but what about the people of Beiping?" Peng Dehuai's face was full of depression.

The two walked into the headquarters, and Runzhi, Zhu De and others were already waiting inside. "You two have just come back just in time, and the battle has greatly exceeded our expectations. I just received news that the Japanese army in Zhangjiakou, Baoding, and Cangzhou has retreated, and the Japanese army in Beiping is also retreating, you didn't expect it! "It's so hard that the Japanese army wants to blow up Beiping!" Peng Dehuai asked urgently. Runzhi shook his head and said: "According to the Beiping Hidden Arrow report, there are no Japanese troops in the inner city of Beiping. ”

"At present, the vanguard of Chen Cheng's 4th Corps is advancing towards Beiping, and it is estimated that it will arrive in Beiping tomorrow morning. We tried our best, but we didn't expect Beiping City to be easily recovered, which is really funny. There was no sign of retreat from the Japanese army in Tianjin, which showed that the Japanese army had to form a new defensive line based on Tianjin, Tangshan, and Shanhaiguan. "Chairman, Okamura Ningji took the initiative to give up Beiping, could it be related to the army's departure from Outer Mongolia?"

Now this can be confirmed, there is no intention to plant flowers and flowers, and there is no intention to plant willows and willows. If my judgment is correct, it was the Soviet side that revealed the news of the troops leaving Inner Mongolia to the Japanese, with the intention of adding time to use military means to solve the Outer Mongolia problem. It was precisely when the Japanese army saw this that they pushed the boat down the river, trying to use Soviet Russia to save their fate. Stalin reacted very coldly, and the Soviet ambassador was paralyzing us by simply verbally protesting that we would comply with the choice of the Mongolian people. ”

"The abnormal reaction of the Soviet side shows that a military conflict between China and the Soviet Union is inevitable, and I am worried about the escalation of the war!" Peng Dehuai said. "Before Japan surrenders, the Soviet side will not move, and then the congregation will betray their relatives and leave. However, a military conflict in the Outer Mongolian steppe is inevitable, and the Soviet side will definitely take the form of a surprise attack, so we must prepare for it in advance. In the battle for territory, we must not retreat. Ouyang Jian's tone was firm.

"If anyone does not offend me, I will not offend, but if anyone offends me, I will offend, and it is not a big deal. In any case, Beiping returned to us unharmed, and the result was exactly what we wanted. It just so happens that Chief of Staff Ouyang is back, and it is rare for everyone to gather like this, and today I will do the Dongda Tooth Sacrifice. "The chairman talked and laughed and infected. In a famous restaurant in Ruijin, everyone sat down. During the meeting, it was decided that the forest department would enter Outer Mongolia in August and take military control of the area east of Ulaanbaatar.
