After the 10th Division was completely annihilated, the Eighth Route Army immediately divided into two routes, and continued to capture Zhaodong all the way to the east, approaching Harbin from the east.The other way is advancing in the direction of Tailai, preparing to attack Tailai.Anda was lost, the 10th Division was surrounded and annihilated, and Yamada Otozo was annoyed and ashamed, but the Japanese army in Heilongjiang suffered heavy losses and was no longer able to engage in a large-scale decisive battle with the Eighth Route Army, unless troops were drawn from the Liaoning battlefield to support Heilongjiang.However, the main force of the Eighth Route Army entered Liaoning in a big way, posing a mortal threat to the Japanese army, and Yamada Otozo originally planned to concentrate his forces to destroy the main force of the Eighth Route Army entering Liaoning first, and if he transferred troops from Liaoning, it would inevitably affect his overall plan.And due to the long distance, it was impossible for the Japanese reinforcements to arrive in a short time, and after weighing the pros and cons, Yamada Otozo finally had no choice but to take a defensive position in Heilongjiang for the time being.Subsequently, Yamada Otozo ordered the 123rd and 124th Divisions to stop attacking Fufu County and immediately withdraw to the Nehe River to take a defensive position.The 1st and 8th Divisions of the Japanese Army immediately abandoned Tailai and retreated to Baicheng.Because at this time, the 1st and 8th Divisions of the Japanese Army had not fully recovered their combat effectiveness, and Tailai was only a small city after all, in case it was surrounded by the Eighth Route Army, the 1st Division and the 8th Division would be in danger.After the Japanese army retreated on its own initiative, the Eighth Route Army regained Tailai and Ulanhot successively, and approached Baicheng from the north and west.Although Yamada Otozo decided to take a defensive position in Heilongjiang, as the power of the Seventh Column of the Eighth Route Army in the Heilongjiang area gradually grew, Yamada Otozo was still worried.So Yamada Otozo finally decided to transfer a division from the Liaoning battlefield to garrison Tongliao, ready to support Baicheng at any time, and another division to defend Harbin.In addition, Yamada Otozo transferred more than 20,000 additional troops to the 1st Division and the 8th Division to complete the soldiers of these two divisions.However, at this time, the veterans of the little devils have been almost consumed, and the outbreak of the Pacific War, the Japanese army can only continue to expand its strength, and a large number of new recruits are added to the troops, although the strength of the Japanese army has increased significantly in a short period of time, but the quality of the soldiers has declined significantly.In particular, units like the 1st Division and the 8th Division have suffered heavy losses several times, and the veterans have been exhausted, and even if the soldiers are replenished, their combat effectiveness is much worse than before.The Eighth Route Army entered the northeast region in a big way, and at this time, the headquarters of the Eighth Route Army had already made up its mind to recover the northeast region in one fell swoop.According to the strategy formulated by the headquarters, it absolutely formed a two-sided attack on the Japanese Kwantung Army from the north and south, so that the Japanese army could not take care of each other, and then gradually consumed the Japanese army's strength, and finally annihilated it and recovered the entire northeast region.In order to realize this strategic intent, the headquarters of the Eighth Route Army decided to further strengthen the strength of the troops in the Heilongjiang region, and decided to transfer the main forces of the two divisions of the Seventh Column, the new First Division and the new Second Division, to the north and place them under the direct command of the Seventh Column.In addition, the headquarters of the Eighth Route Army also decided to reorganize a division of the former Shanxi-Chahar-Hebei Military Region into a new Fifth Division, which was assigned to the battle sequence of the Seventh Column, and went north to Heilongjiang together with the new First Division and the new Second Division.The commander of the new Fifth Division is Han Meng, and he is also a rare member of the Eighth Route Army.In this way, the Seventh Column has five infantry divisions, one armored division, one cavalry division, and one artillery division, a total of eight divisions, as well as teaching brigades, special operations brigades, and other units, and the total strength of the entire seventh column has reached 200,000.If we add the main forces of the three provincial military districts under the jurisdiction of the Northeast Military Region, the main force under Li Guotao's direct command exceeds 300,000, and if we add the local troops of the three northeastern provinces, the number of troops will reach 400,000.The headquarters of the Eighth Route Army mobilized more than 400,000 troops from Guannei into Liaoning, thus bringing the total strength of the Eighth Route Army in the northeast region to an astonishing more than 800,000 troops, accounting for 60 percent of the total strength of the Eighth Route Army.For the first time, the Eighth Route Army in the northeast surpassed the Japanese Kwantung Army in terms of strength.At this time, the Japanese Kwantung Army had only about 500,000 troops left, and the consumption of previous major wars was too great, although it was also supplemented, but the main attention of the Japanese government at this time was focused on the South Seas, and the replenishment could not catch up with the consumption at all, so the strength of the Kwantung Army dropped a lot.In May 1942, Yamada Otozo reluctantly scraped together about 300,000 troops and launched a full-scale attack on the main forces of the Eighth Route Army on the front line of Chifeng, Chaoyang, and Lingyuan, in an attempt to first eliminate the main force of the Eighth Route Army in Liaoning, and then turn around and counterattack Heilongjiang.The headquarters of the Eighth Route Army immediately ordered the Eighth Route Army in Liaoning to defend the victorious achievements of the War of Resistance against Japanese Aggression and resolutely resist the Japanese attack.The Eighth Route Army had a certain advantage in terms of strength, coupled with the fact that the Eighth Route Army was on the defensive, relying on favorable terrain and strong fortifications to resist, occupying a certain advantage.As a result, the Japanese offensive was blocked one after another at the beginning, and the two sides fought fiercely for several days, the Japanese army made slow progress, and the attacking troops suffered heavy losses.However, at this time, Yamada Otozo seemed to have lost his mind, completely ignoring the fact that the strength of the two sides had changed to a certain extent, and repeatedly asked the Japanese troops to continue to launch fierce attacks, and the war in Liaoning fell into a stalemate for a while.Qiqihar, in the headquarters of the seventh column of the Eighth Route Army, the main generals gathered in the conference room, Li Guotao held a telegram in his hand, and said with a serious face: "Ladies and gentlemen, the Japanese army has taken the initiative to launch an offensive in Liaoning, and the front-line war is urgent, and the headquarters requires us to take the initiative to attack the Japanese army in Heilongjiang to deal with the friendly forces in the Liaoning battlefield. ”Ma Zhenguo, chief of staff, continued: "So far, our Northeast Military Region, except for the troops of the Liaoning Military Region, which are still in Liaoning, the rest of the troops have been assembled in Heilongjiang, and the total strength of the main forces is about 300,000 people, and we are fully capable of taking the initiative to attack the Japanese army.However, the crux of the matter now is whether the direction of our attack this time is whether to continue to attack Harbin in the east or to attack Baicheng in the south, and this is the most important issue we will discuss at this meeting. ”Li Guotao nodded slightly and said: "Zhenguo, let's talk about the situation of the Japanese army in Baicheng and Harbin first" Ma Zhenguo nodded and continued: "At present, there are two divisions of the Japanese army in Baicheng, the 1st Division and the 8th Division, about 50,000 people, and there is also a 12th Division in Tongliao.The Japanese army in Harbin was relatively small, with only one division and one independent mixed brigade, with about 30,000 troops and less than 40,000 troops. ”aa2705221:
