On October 21, although the Kwantung Army Headquarters urgently ordered the 64th Division and the 13th Infantry Division of the puppet Manchukuo Defense Army to immediately build a defensive line on the line of Pingfeng, Miaodongtun and Xinmiao between Daan and Songyuan to prevent the Chinese army from attacking Songyuan, and at the same time mobilized two infantry brigades to urgently reinforce Songyuan.

However, the opportunity has passed, and in the face of powerful mechanized troops, the almost rigid defense of the Japanese infantry divisions and regiments has fundamentally started to the desired effect. At 14 o'clock in the afternoon of the 21st, Wan Guoquan's headquarters occupied Pingfeng and Xinmiao at 19:10, as for the infantry brigade that continued to be stationed in Miao Dongtun, Wan Guoquan didn't care at all, and after opening the passage to Songyuan, the large army did not make any stops, and went straight to Songyuan.

Songyuan, located in the central and western part of Jilin, is located in the triangle of Harbin, Changchun and Daqing, at the southern end of the Songnen Plain, on the bank of the beautiful Songhua River, adjacent to Changchun and Siping City in the south, bordering Baicheng City and Tongliao City in Inner Mongolia in the west, and facing Heilongjiang Province across the Songhua River in the north. It is one of the most important cities in Jilin Province of the puppet Manchukuo, and it is also an important pass to Changchun, the new capital. The fall of Matsubara was the cause of Yamada Otozo's domestic criticism, and even the base camp, which had always watched directly and did not express opinions, sent a special telegram to the Kwantung Army Headquarters to reprimand the Kwantung Army Command for its inaction.

General Yamada Oto-san already had a most ominous premonition, although the troops of South Manchukuo performed well, and nearly 600,000 troops of China were dragged in the South Manchurian region, but the war situation in the Central Manchurian and North Manchurian regions was not very optimistic, first of all, on the North Manchurian side, the administrative regions of the 14 provinces and 2 special cities of the puppet Manchukuo had long since ceased to be the grand occasion of the past. Rehe Province was completely occupied by Han Yunhua's troops as early as two years ago, and even caused the Second Division to be severely damaged twice and the division commander to be killed.

Soon after the start of the war, Heihe, the capital city of Heihe Province, was captured by the Soviet army that night, Sanjiang Province and Xing'an North Province were also occupied by the Soviet army within two days, so far 3 provinces have completely fallen, and another 6 provinces are under the absolute threat of the Chinese army, and now the Kwantung Army and the puppet Manchukuo nearly 1.2 million troops have lost nearly 300,000, only 3 days after the war, the Japanese puppet army has 4 divisions were completely annihilated, 8 divisions were defeated, and 4 divisions have become toothless tigers, Dragged by Chinese troops in the Baicheng area. In addition, nearly 100,000 Manchukuo soldiers were either annihilated or surrendered voluntarily, and 300,000 was just a conservative number.

It's only been 3 days, and at this rate, the entire Kwantung Army will completely collapse in half a month at most, and the consequences are too serious. Regardless of his own face and the honor of his soldiers, General Yamada Otozo almost pleaded with the country for help, hoping that Japan could mobilize at least 100,000 reinforcements to reinforce the puppet Manchurian region, otherwise it would be difficult for the Kwantung Army to hold Japan's money bag under the joint attack of China and the Soviet Union.

The importance of the puppet Manchukuo region to Japan is self-evident, the Japanese invaded China for the sake of interests, only under the drive of interests will they be so disrespectful and honest, and the natural resources of the northeast region are very rich, naturally become the object of contention among the Japanese, according to the 1936 puppet Manchukuo "State Council" resource survey report, the puppet Manchukuo region coal reserves of about 3 billion tons, iron reserves of about 4 billion tons. Other minerals are gold, magnesite, bauxite, oil shale, diamond, etc. Forestry and fishery resources are also very abundant, and most of these things cannot be produced by barren Japan, for Japan, the Northeast region is not only their money bag, but also an important resource base for them to dominate Asia and dominate the world. In order to exploit it, more directly, it should be to plunder the resources of Northeast China, which the Japanese can be described as painstakingly managed. They established steel and chemical industrial bases in Anshan and Benxi. In Fushun, Benxi, Fuxin to establish the center of gravity of the coal industry. Magnesite mining is concentrated in Haicheng and Dashiqiao. Hydropower generation is concentrated in Jilin and the Yalu River. The center of the machinery, munitions, and aircraft industries was Mukden (present-day Shenyang), while light industries such as textiles and food were concentrated in Dalian, Dandong, Harbin, Qiqihar and other cities. …,

At the same time, after the establishment of the puppet state of Manchukuo, funds from other Japanese chaebols quickly poured into the puppet state of Manchukuo. After 1937, the puppet state of Manchukuo adopted a policy of economic control over the industrial sector, implementing the principle of "one industry and one company", and a monopoly company was established in each industry. According to this principle, the Manchurian Railway handed over its own industrial division, which was reorganized to form the huge Kang Tseen - Manchuria Heavy Industry Joint Stock Company (Manchukuo), which monopolized all the steel, coal, chemical and electric power industries in the territory of the puppet Manchukuo. In addition, more than 40 special companies were also set up, including the puppet Manchurian telegraph (telephone and telegraph) company, the puppet Manchurian Machinery Manufacturing Company, the puppet Manchurian mining company, the puppet Manchurian airline, the Manchurian artificial oil company, the puppet Manchurian textile company, the puppet Manchurian woolen company, the puppet Manchurian chemical industry company, the puppet Manchurian forestry company, the puppet Manchurian gold mining company, the puppet Manchurian livestock company, the puppet Manchurian aquatic products company, the puppet Manchurian tobacco company, the puppet Manchurian agricultural commune, and the puppet Manchurian development commune. These clubs were jointly funded by Japanese investors and the puppet Manchukuo, and when they made profits, they were divided according to the proportion of the shares of both parties, and when they lost money, the puppet Manchukuo government guaranteed 10 percent of the profits from the Japanese investment. Therefore, the puppet Manchurian region is a community of interests between the Japanese government and the Japanese chaebols, and the Japanese chaebols' investment in China's northeast region accounts for more than 80 percent of their overseas investments.

Although the fighting in Southeast Asia continued to escalate, and the progress of the Japanese Southern Army was not smooth, and the Burma battlefield was defeated and retreated, the opinions of the whole Japanese were surprisingly unanimous, and they immediately sent troops to reinforce the puppet Manchurian region.

However, there are opinions on how to reinforce this reinforcement, and some people advocate mobilizing troops from within the country to go north for reinforcements. However, more people believe that the mainland is now threatened by the Americans, and American warships have appeared on the islands of Okinawa several times, as if they want to use them as a springboard for attacking the Japanese mainland. And now there are not many troops in Japan, and several general armies are also dissatisfied, unable to cope with the future war situation, and the southern army cannot be ignored, the puppet Manchukuo side is the Soviet Army, but the Southern Army is facing the Sino-US coalition army, compared to the Sino-US coalition army is more worrying, after all, the Soviet Union's main energy is still in Europe, so the vast majority of people advocate mobilizing troops from North China or Central China or South China to the north for reinforcements.

After studying the matter, the Japanese military department decided to mobilize the 37th and 69th Divisions of the North China Front, the 13th Division of the Central China Front, and the 104th Division of the 23rd Army stationed in South China to reinforce the Kwantung Army. However, these Japanese divisions and regiments all have their own combat missions, and it will take a while to assemble, so the base camp will load the two infantry divisions that have just been formed in China and transport them to the northeast region.

After receiving a clear reply from the base camp, General Yamada Otozo did not appear very happy, because judging from the current situation, if there were no large number of planes and tanks and other heavy weapons, it would be difficult to withstand the attack of the Chinese and Soviet Army, especially the aviation unit of the Kwantung Army has not recovered since it suffered a crushing defeat in the sky over Guisui, and less than 100 of the 400 Zero fighters promised in China have been transferred, and the entire Kwantung Army aviation unit is extremely weak. The scale is getting bigger and bigger every time. He saw very clearly yesterday's air raid on Xinjing's Shina fighters, all of them American P40, 80 planes.

According to the information obtained by the intelligence department, which did not hesitate to expose spies who had been hidden for many years, Han Yunhua's headquarters now has nearly 1,000 fighters, and although these fighters have a large and varied model, including the P40 of the United States, the I-15, 16, and Lag-5 of the Soviet Union, and the Zero fighters produced by the Empire, the combat effectiveness of this aviation unit is not bad. The chariot unit under Han Yunhua's department in China is also extremely powerful, with nearly 700 tanks of various chariots, which is equivalent to a complete chariot division. Together with the troops in the Soviet direction, the Kwantung Army was already far behind the combined forces of China and the USSR in terms of heavy weapons. …,

However, General Yamada Otozo knew that it would be difficult to get domestic aid, and he also knew about the domestic situation, and the economic crisis of '29 almost destroyed the entire national economy of Japan, and if it were not for the plundering of a large amount of materials with the help of foreign wars, Japan would have declined long ago.

In the early days of the war, Japan won one after another, and the plundered resources were extremely huge, so the war made Japan rich. However, after being mired in the quagmire of the Chinese battlefield, Japan's economy began to decline rapidly, and after the outbreak of the Pacific War, huge military expenditures were on the verge of dragging down Japan's finances, which had almost dried up. Now the domestic economy is exhausted, for the sake of war, Japan not only plundered the economy of the colonies, but also used the domestic economy cruelly, so that due to the extremely abnormal development of Japan's economic development, the national industry and mining industry withered, the rural economy went bankrupt, and the national economy only served the war.

Now it is impossible to come up with a large amount of money to form a new mechanized army in the country, and it is too late in time. General Yamada Otozo is ready to give up the entire Northern Manchuria, as long as he holds on until the arrival of imperial reinforcements, then the Kwantung Army still has a lot to do.

At this time, the biggest threat was the huge mechanized unit of the Soviet Red Army and the chariot unit under Han Yunhua's department, and the Soviet Union's mechanized unit, General Yamada Otosan, had already sent the first tank division to meet the battle, and as for the mechanized unit under Han Yunhua, Yamada Otozo really couldn't think of a way. In desperation, General Yamada Otozo had no choice but to order Lieutenant General Araki to immediately send a group of aircraft to bomb all suspicious targets along the Matsubara line, and to find the hateful Shina chariot force and destroy it
