Lao Jiang was completely disappointed when he learned the news of Liu Zhi's defeat and escape, and immediately ordered Wei Lihuang to stop attacking the Soviet area in order to concentrate his forces to deal with the Red 15th Army, which seemed to be lying in Hangzhou and was not ready to leave.

Although Wei Lihuang regretted that the "suppression of bandits" gave up halfway, under the combined efforts of old Jiang Enwei, he still honestly went north to receive and rectify Liu Zhi's defeated army. However, with Wei Lihuang's steady style of employing troops, if he wants to lead his troops north to Hangzhou, he will have to wait at least ten days and a half months later, which makes Lao Chiang extremely anxious, and the Red Army has occupied Hangzhou but has not been able to exterminate it for a long time, which is undoubtedly a heavy blow to his prestige, if the local powerful faction takes the opportunity to join in the fun, he will really be anxious, especially in the past two days, the damned Japanese ambassador has come over again and again to protest and claim compensation as if he didn't know how to be tired, and threatened to send troops over to "help suppress" him, which made Lao Chiang even more angry

What really reassured Lao Jiang was the return of the elite 200,000 national troops of Xue Yue's conquest of the Central Red Army, at least Nanjing and Shanghai were safe. In fact, the reason why Xue Yue gave up chasing the Central Red Army was because the Red Army actually ventured into the Jiajin Mountain, which was said to be impossible for even a bird to fly, and the national army was dumbfounded, and no one dared to follow all the way anymore. Moreover, as soon as the Sichuan warlords saw that the threat of the Red Army was lifted, they immediately began to squeeze out Xue Yue's central army, and Xue Yue could not stand in Sichuan, so he had to withdraw his troops in depression and return east. Originally, Lao Jiang was not very satisfied with this, but this matter was crooked, so that the new reinforcements in the Yangtze River Delta region, which is now seriously understaffed, plus the troops of Hu Zongnan's First Army and Sun Lianzhong, who had been transferred to southern Anhui by telegram, Lao Jiang could finally sleep peacefully.

After that, the national army suspended all offensives, but instead attracted the attention of Hu Weidong and Su Yu, in order to disrupt the enemy's steady increase in the deployment of troops, and in order to obtain a buffer zone, Hu Weidong divided a part of his forces, and occupied all the counties around Hangzhou that had not been garrisoned by the national army as quickly as possible, and put on a jiashi who was ready to live in Hangzhou for a long time. But now there is only one unit in the hands of Lao Chiang who can rush to Hangzhou immediately and is strong enough to ensure that it will not be easily eaten by the Red 15th Army, that is, the Central Military Academy Teaching Corps, but the German adviser General Alexander von Falkenhausen strongly opposed Lao Chiang sending this elite army to the battlefield, because even an ordinary soldier in this army will be a future officer of the national army, and it is simply a crime to let him die as a soldier. Not to mention that this time the situation is much more difficult. But Lao Chiang was still stubborn, because he had to show enough liliang to the major shili in the country, otherwise if those local factions were also encouraged to raise troops against the central government, the situation would be even more out of control. However, the teaching corps, which Lao Chiang had high hopes for, fell into the encirclement of the main force of the Red 15th Army because of the classified telegrams of the Nationalist army

However, the teaching corps is worthy of being the teaching corps, although it is surrounded by the superior strength of the Red 15th Army, and it is inferior in heavy equipment (although the teaching corps is well-equipped, after all, it is only a division-level unit. Even the formation was disrupted by the "flank detour" of the Red 15 th Army again, and the officers and men who were forced to fight separately still resisted stubbornly, and after several days of fierce fighting, the Red 15 th Army still did not eat all the enemies in the encirclement, but it paid a huge number of casualties of more than 10,000 people, and the consumption of ammunition hit a new high since the establishment of the Red 15 th Army.

"No, we can't fight like this, we can't fight a war of annihilation for the sake of fighting a war of annihilation, after all, there are still Japanese people eyeing each other, and the situation during the War of Liberation is completely different, the importance of "development" is much higher than "annihilating the enemy", if a battle can not strengthen their liliang, then this battle should not be fought. The teaching corps is a very special unit, and the ordinary soldiers in it will all be officers in the future, and it is very difficult to transform them, which means that this battle will definitely be a loss, and the difference is only that the loss is more and less. Considering the future War of Resistance, the purpose of our current war is development and self-preservation, so it is enough to defeat the Teaching Corps so that it can no longer threaten us for a period of time, and there is no need to fight to the death at all costs, increase unnecessary casualties and waste too much ammunition as the 74th Division was annihilated and reorganized during the War of Liberation. Hu Weidong suddenly came to his senses, immediately asked for back command from Su Yu, and immediately ordered the encircled troops to make way of a gap, and taught the general team to see that there was a way to live, and the determination to fight to the death suddenly faded, and they fled one after another, while the Red 15th Army pursued and killed the enemy, destroying most of the enemy army, while the losses of the Red Army were greatly reduced compared with the previous siege of the enemy army...,

In this battle, Su Yu and Hu Weidong each commanded half of it, and the result was quite satisfactory, but generally speaking, the practice of delegating command and then suddenly retracting it is very hurtful, and fortunately, Su Yu has a large measure, otherwise the two may have a disagreement in the future. After listening to Hu Weidong's analysis, he also thought that his idea of attaching more importance to "destroying the enemy" was inconsistent with the situation of the Red 15th Army now surrounded by strong enemies. After this battle, Hu Weidong and Su Yu cooperated more and more like a fish in water, and gradually became a pair of golden partners that would make any enemy feel terrified

Hu Weidong's intervention not only changed the battle itself, but also made the first army of the national army that rushed to the rescue crashed headlong into the iron plate, and the red fifteenth army that was free of hand concentrated all the main force of more than 100,000 people to deal with Hu Zongnan's army, which was really relaxed and happy, this time Su Yu finally fought a war of annihilation, and the whole army completely broke the resistance of Hu Zongnan's first army in less than two days after fierce fighting, and killed and captured more than 30,000 people of the national army at the cost of more than 5,000 casualties. Although Hu Zongnan broke through under the escort of his subordinates, seeing that his "first army in the world" was now less than 1,000 people, Hu Zongnan couldn't help but feel sad and cried bitterly on the spot. So far, the Red 15 th Army has won five battles and five victories, killing and capturing more than 100,000 enemy troops, and the rich people in Nanjing, Shanghai, and other places have fled one after another because they are afraid of the Red Army coming. However, after a series of victories, Hu Weidong was surprised to find that the situation of the Red 15th Army was even more dangerous than before the war
