On 22 March, the Iwanaga Detachment of the 34th Division of the Japanese Army, which was following Wang Heng's troops, first entered the ambush circle carefully set up by Sun Yumin.

The first to engage in a firefight with Iwanaga was Wang Heng's 417th Regiment, and like Oga Shigeru, Iwanaga, who was the commander of the Major General's Brigade, was also an arrogant guy, and in his eyes, the resistance of the beaten "deserted" Chinese army was just a "dying struggle", and it was simply unable to resist his advance.

So from the beginning of the firefight, Iwanaga copied Oga Shigeru's tactic: a strong attack.

Wang Heng's 417th Regiment almost arrived at the front and rear feet of the Yanyong Detachment, but the two regiments led by Shi Zhonghua had already built a defensive position, how could it be so easy to be captured, and the position of the 139th Division was not only connected to the position of the 81st Division, but also had a reserve position behind, not to mention a small Yanyong detachment, which was the burial place chosen by Sun Yumin for the 34th Division of Dahe Mao.

Seeing the large army of devils fall into his carefully arranged big pocket step by step, Sun Yumin's mood was much better, and there was a smile on his face. His every move directly affected the people in the headquarters, and the original suppressed emotions were already dissipated by the good news that came from time to time, and now coupled with Sun Yumin's good mood, naturally those so-called "negative emotions" have disappeared completely.

However, before Sun Yumin was happy for too long, a telegram sent by Luo Zhuoying made Sun Yumin's brows lock again.

Luo Zhuoying informed Sun Yumin in the telegram that the 33rd Division of the Japanese Army, which had been besieged by the 70th Army, the 72nd Army, and the 74th Army in the mountains between Shangfu, Ganfang, and Kuzhuao, and that after several days of fierce fighting between the two sides, although the 33rd Division suffered heavy casualties, with the assistance of Japanese aircraft, it finally broke out and returned to the Fengxin area.

This situation was completely unexpected, with his previous assumptions, not to mention the assistance of the 70th Army and the 72nd Army, Guangwang Yaowu's 74th Army was enough to eat this third-rate division of the Japanese army. After all calculations, the devil's plane was missed, and the national army was too short of air defense weapons, even such a trump card as the 74th Army, not to mention other troops. Luo Zhuoying reminded Sun Yumin in the telegram that he must be careful of the devil's plane, he gave an example, the 57th Division of Yu Chengwan's Division, which succeeded Li Tianxia as the division commander, is an iron army with outstanding military achievements, and the soldiers are not afraid or brave, but in front of the devil's plane, they still seem too weak, and after paying a lot of casualties, they still did not seal the mouth, so that Sakurai Provincial Third and his 33rd Division were able to retreat with their whole body.

"Junzao, Chief Luo, they also tried their best, although they did not annihilate the 33rd Division of the devils, but at least they beat them back, and they did not pose a threat to our army for the time being." Deng Dongping comforted Sun Yumin on the side, he thought that Sun Yumin was angry that he had not eaten a third-rate division of the devil with the strength of the four armies.

Seeing that Sun Yumin didn't respond to him, Deng Dongping said again: "In this matter, I heard that Commander Xue also blamed Chief Luo, and even Commander Chen personally called Chief Luo to ask about this matter, he is already under a lot of pressure, if we still dwell on this matter, I am afraid it will make Chief Luo feel cold, after all, he is still good to us, are you right?" Military seat. Deng Dongping thought that Sun Yumin was silent about the escape of the 33rd Division, so he said such a long sentence, but he didn't get to the point at all.

How could Sun Yumin be resentful, not to mention that he had received Luo Zhuoying's favor, not to mention that he clearly knew that in less than a year, Luo Zhuoying would be personally appointed by Lao Jiang to replace Wei Lihuang, who had not yet arrived, as the commander-in-chief of the Chinese Expeditionary Force. Although he was transferred back to China at the end of 1942 due to irreconcilable contradictions with General Stilwell, chief of the General Staff of the Expeditionary Force, Li Zhipeng and a number of other famous generals of the Nationalist Army were under his control, but it still did not affect his status in the heart of Lao Chiang and in the army. Although these are all things in the future, it can be seen that Xue Yue is actually not able to have much influence on Luo Zhuoying, not to mention that Xue Maniac will blame him, aside from the fact that both of them are fellow villagers in Guangdong, how about Xue Yue dare to treat Chen Cheng's civil engineering department? The code of the acting commander of the Ninth Theater on his head has not been removed, and Chen Cheng is the real nominal commander of the Ninth Theater.

"Dongping, you are too worried, I have not complained about Chief Luo for not annihilating the 33rd Division of the devil, and I am not worried that Chief Luo will be punished by the peak. I'm just thinking about how to deal with the devil's plane, but I can't think of a suitable way to deal with it. After hearing the second paragraph of Deng Dongping's words, Sun Yumin had to respond to him, if he didn't say what he thought in his heart, I was afraid that the entire command would be depressed with his low mood.

"Junza, I have an idea, can you listen to it?"

"Speak up and listen." Sun Yumin was having a headache how to deal with the devil's plane, and when he heard that there was a way, it was really a pillow when he was sleepy.

"Junza, although I don't know much about the devil's plane, I have discovered a phenomenon." Deng Dongping said: "That is, they are the same as the devil infantry, they are not good at night fighting, I have almost never heard of any national army unit that has been bombed at night, do you think we can take advantage of this?" ”

Deng Dongping's words made Sun Yumin feel like Daigo and made him wake up all of a sudden.

He was only thinking about how to prevent the devil's plane, and he didn't think about how to avoid the devil's plane at all.

The Air Force during World War II was completely unable to dispatch day and night like later generations, and even throwing bombs relied on the pilot's naked eye and experience. And the speed of the flight is not particularly fast, there is no Japanese airfield around Nanchang, and the nearest devil military airfield from here is far away in Jiangsu, unless a battle plan is drawn up in advance, otherwise when there is a large-scale battle here, even if they take off to support immediately, it will be a few hours later, so if you want to deal with the 34th division of the devil, it will not necessarily be hit by the devil air force.

"Dongping, this discovery of yours is of great help." Sun Yumin gave a rare compliment, in fact, he should have thought of this a long time ago, but once people's thinking gets into a dead end, it will really be unthinkable for a while. Otherwise, how could there be a saying that "three stinkers are better than Zhuge Liang".

Although he thought of how to avoid the devil planes attacking the Japanese army, he still had to endure the devil's attacks and plane bombing for at least one day. Don't underestimate this short day, if you want to hold this day, you really have to fill it with human lives, if the devil's 34th Division is too far away from the front of the 139th Division's position, maybe you will have to endure it for one more day.

It's not that Sun Yumin can't wait for this day, but if he has to wait for this day, the troops will have a lot of casualties, and if the 81st Division and the 139th Division are really wiped out in this battle, then even if he wins this battle, then he will not have the pleasure of victory.

Fortunately, judging from the reconnaissance information gathered by Wu Linsheng, Oga Shigeru's troops have been accelerating forward, after all, he is not at ease to put the Iwanaga detachment far ahead.

In addition to this good news, Luo Zhuoying also sent a telegram that excited Sun Yumin, and he sent the 74th Army to help in the battle.

In fact, Luo Zhuoying sent Wang Yaowu of the 74th Army over with some caution, which involved the contradiction between the civil engineering department and He Yingqin's department. The 70th Army and the 72nd Army, which besieged the 33rd Division, did not take the credit for the greatest casualties and contributed a lot of effort, and let the 74th Army rob them all, but put the big black cauldron that let the 33rd Division go, which made Luo Zhuoying, who was the commander-in-chief of the 19th Group Army, very unhappy, isn't your 74th Army very capable of fighting? Okay, let's go and help Sun Yumin fight Da He Mao. If you win the battle, you can help Sun Yumin, and you can take some credit; If he loses the battle, with Sun Yumin's essence, it would be strange if he didn't put all the responsibility on Wang Yaowu. Although He Yingqin is deeply trusted by Lao Jiang, if he really turns his face with Chen Bui, he may not have much upper hand, and there is also a Chen Cheng who can compete with him.

Luo Zhuoying's thoughts Sun Yumin naturally didn't know, and he didn't think about it at all, Wang Yaowu's 74th Army was coming, it was really good, at least he didn't have to worry about his periphery being attacked by the Japanese army that suddenly appeared.

As expected, the position of the 139th Division, which was struggling to defend the Japanese attack, was frantically bombed by devil planes, and the 417th Regiment had already been damaged when Sixi was broken, and after being bombed by this pass, the casualties were even heavier. Iwanaga did not miss this rare opportunity, and commanded the infantry of nearly a brigade to attack the position of the 139th Division in a menacing manner. The 417th Regiment was obviously unable to withstand this wave of attacks, and even Wang Heng himself was slightly wounded, but he did not retreat, and personally controlled a Czech machine gun, strafing the devils who came up in a straggler line.

Fortunately, Shi Zhonghua sent the 423rd Regiment as a reserve to repel this wave of attacks by the devils.

When looking at such a big loss of his 417th Regiment, Wang Heng, who was already wounded, was in pain, and even had the idea of going to the military headquarters to question Sun Yumin, the battle was like this, why didn't he send reinforcements, did he want to fight the 139th Division?

Shi Zhonghua asked the 423rd Regiment to replace the 417th Regiment and the 422nd Regiment with heavy casualties, but what Wang Heng didn't expect was that before he could eat after bandaging his wounds, the sound of aircraft engines came from the sky again.

This can frighten Wang Heng, the previous bombardment has already caused heavy losses to the 139th Division, if there is another wave, then it is estimated that the 417th Regiment and the 422nd Regiment that have just been withdrawn from the position will have to be thrown back into it, otherwise the 423rd Regiment will not be able to withstand it at all.

As he looked up anxiously at the sky, the telecommunications officer ran to deliver a message.

The message was sent by Sun Yumin, and the content was very short, only four words: Keep it until evening.

Although there are only four words, but for Wang Heng, it is more timely than the life-saving medicine, although he doesn't know whether to retreat or attack the military seat until the evening, but he at least knows that there is no need to fill in the lives on the position.

The bombing of the front wave planes left a lot of craters, which became the best place for the officers and men of the 423rd Regiment to dodge the bombs, after all, the probability of two bombs falling into the same crater is too small and too small.

But in spite of this, the explosion power produced by the aerial bombs weighing tens of kilograms falling on the position is really beyond the strength of human flesh and blood. Not to mention being within the killing range of the explosion, even the violent shaking of the ground and the shock wave generated by the explosion can shatter a person's internal organs. So in fact, many soldiers were not killed by the bombing, but shocked to death. Like most of the fire scenes in later generations, there were by no means many people who were burned to death, but many people were killed by smoke.

If it had been replaced by the previous 139th Division, which had experienced two waves of such crazy bombardment, it would have abandoned its position and fled. But now, even if it has been hit so hard, whether it is the previous 417th Regiment, the 422nd Regiment, or the current 423rd Regiment, they have not taken half a step back. What is Change? That's the change! The reason why the Eighteenth Army and the Seventy-fourth Army can become the Iron Army and become the thorn in the side of the devil is because they have a heart that regards death as home, from the general to the soldier. The current 139th Division is also leaning on this, the 81st Division is also the same, and the entire 12th Army is also the same, according to Luo Zhuoying's words, Shangfeng attaches so much importance to the 12th Army, if Sun Yumin does not bring the 12th Army into a trump card unit no less than the 18th Army and the 74th Army, it will be in vain for Shangfeng's hard work.

After the bombing, the devil plane swooped and strafed in a conspicuous manner, which made the officers and men of the 423rd Regiment below grit their teeth with hatred, and a few machine gunners operated the Czech style to strafe the enemy planes that were diving, but they didn't know the word "measure in advance", how could they hit the plane. Not to mention that it didn't hit the plane, it also attracted a frantic strafing from the devil's plane, and several people were smashed by the on-board machine guns that swooped in.

Shi Zhonghua's eyes were about to erupt with fire, especially when he saw that the devil pilot had obviously run out of bullets, but still continued to dive down, flaunting his wings when he pulled up, and deliberately showed the bright red devil flag painted on the fuselage to the Chinese defenders, which made Shi Zhonghua even more angry, he picked up a Czech style, rushed out of the position, stood on a dirt slope and shot wildly at these unstoppable devil planes, but saw them gradually disappear into the shadow of the sky, It doesn't play any other role anymore.

As soon as the plane left, the devil's infantry continued to touch the position, which seemed to have become a fixed routine for the devil's attack, but it was this routine, and the Chinese army was helpless against them.

The common tactic of the devils is that the artillery bombards first, and after the artillery bombards the infantry, a wave can penetrate the defense line of the national army. And now it is replaced by an airplane, and the infantry rushes after the plane is blown up, obviously the plane is more powerful than the artillery, but after a day of fighting, he still did not take this batch of Chinese defenders, which made Iwanaga a little annoyed, so in this wave of attack, he sent an extra squadron, and he wanted to take it before dark, so that his soldiers could have a good night's rest.
