However, Yang Ruihua still underestimated Gu Shoufu, or underestimated Gu Shoufu's madness. At five o'clock, the Japanese army took cover alternately and slowly withdrew from Jining City, giving up all the results of a day's hard work.

Seeing that the devils had really retreated, the soldiers cheered excitedly, of course, they were entitled to pride, because they had once again repelled the most elite 6th Division of the Japanese army.

But Yang Ruihua and Zhang Hao in the underground headquarters of Jining City didn't think much about it, they knew that the Japanese army would not give up so easily, after all, the North China Front Army Headquarters gave Gu Shoufu, an old devil, a very limited amount of time, although I don't know how many days it will be for the time being, but it won't be too long. The Japanese army is retreating now by no means for the sake of retreat, there must be some conspiracy.

Yang Ruihua pondered for a while and said: "Lao Zhang, I don't think Gu Shoufu will give up, he has at least more than 10,000 people under Jining City, how can he withdraw like this, there must be a conspiracy here, we must guard against it."

Zhang Hao is an old soldier, he has a keen observation of the war, he smiled and said: "Lao Yang, I agree with this sentence, I don't think Gu Shoufu has this kind of mind, with his kind of character that will take revenge, he will not give up if he can't capture Jining City." To be honest, I really admire people like him, hehehehehe"

Yang Ruihua glanced at Zhang Hao and said: "Let the commander hear this, you kid will shed his skin even if he doesn't die, admire Gu Shoufu, don't you know how much the commander hates this Gu Shoufu and the Sixth Division?" ”

Zhang Hao quipped: "Our old Zhang doesn't dare to provoke the commander, but I know that the commander hates devils, haven't you heard that this time the commander has controlled all the Japanese expatriates in Chengde City, but I don't know if these people will be clicked?" ”

"Not really, I know the Commander better than you, although he hates the Japanese very much. Moreover, there is no shortage of killing prisoners in the field, which is a semi-public matter in our military region. However, the commander is still very principled, and he will not do anything to slaughter civilians, don't worry, I think the commander wants to blackmail Shouichi Terauchi," Yang Ruihua said with a smile.

Zhang Hao said: "Lao Yang doesn't know if you have noticed, in fact, the commander and this Gu Shoufu have very similar personalities, they will not give up until they achieve their goals, and they will do whatever it takes to achieve their goals, and it is really terrible to be an enemy with such a person."

"Don't say it, the two of them are really a little similar, but the nature is different. Gu Shoufu is a real aggressor, he came to China to enslave our Chinese people, and his cruelty and ferocity are all inflicted on the suffering of our Chinese nation. But our commander is a national hero, his ruthlessness is only shown to his enemies, and to the masses of the people, our commander is still a man who respects everyone Mr. Han. Yang Ruihua said.

Zhang Hao said: "That's right, but Lao Yang, why did you say that the devil retreated in a good manner?" What kind of medicine is sold in the gourd of Gu Shoufu, an old devil? ”

Yang Ruihua was actually puzzled in his heart, but after Han Yunhua's teaching for so long, Yang Ruihua still had a little experience in commanding battles, thought about it and said: "The devil's retreat now is not to enter the east of Jidong, it is likely that he is using some kind of trick against us, and this kind of thing will cause irreparable damage to themselves while causing us harm." Of course, it is possible to use some weapons and other things that we haven't seen before, and anyway, it will definitely not be a good thing for the devil to retreat now. ”

After Yang Ruihua's reminder, Zhang Hao suddenly thought of a very terrible thing, and immediately turned to Yang Ruihua and said, "Old Yang, do you think the devil will use poison gas to deal with us?" ”

Yang Ruihua also thought of this problem, but Yang Ruihua immediately thought of another situation, so he said: "Probably not, these days, the devils have fired some poison gas bombs at our positions almost every day, and that should be their Red No. 1 special smoke, but the commander has been prepared for a long time, and these things have almost no effect on us." I don't think Gu Shoufu didn't find out about this situation, how could he stupidly use poison gas bombs to attack us. But it's not impossible to take precautions, Lao Zhang, you still go to the battlefield to take a look, and tell the soldiers to guard against the Japanese army's poison gas bomb attacks. ”

"I'll go." After speaking, Zhang Hao turned around and walked out. However, no one expected that Zhang Hao's departure would become a farewell between him and Yang Ruihua. ,

Neither Han Yunhua nor Yang Ruihua expected the madness and cruelty of the Japanese army, as Zhang Hao expected, the devils retreated in order to use poison gas bombs. But the poison gas used this time was not the Red No. 1 in the cognition of Yang Ruihua and others, but the Yellow No. 1, which is known as the prestige in the Japanese Army. The so-called Red No. 1 and Yellow No. 1 are both chemical weapons used by the Japanese army, which is known as poison gas bombs. In the Japanese invasion of China, the name of the poison gas bomb is special smoke, and due to the different substances that constitute the poison gas, the code name is also different, so the so-called yellow No. 1 and red No. 1 and other titles appeared.

Most of the poison gases used by the Japanese army were similar to tear-jerking phenylchloroacetophenone, vomiting biphenyl arsenic chloride and biphenyl arsenic cyanide, erosive mustard and Lewis gas, and occasionally asphyxiating phosgene, potassium chloride pyridine and cyanic acid gas. There are clear international regulations on the use of chemical weapons, and the chemical weapons used by the Japanese army are internationally prohibited. In order to cover up the crime of conducting poison gas warfare, the Japanese army established a strict secrecy system, stipulating that poison gas was called special smoke, and the markings of ammunition and ammunition boxes must be removed before they could be delivered to the troops. For example, yellow 1 indicates mustard gas, yellow 2 indicates Lewis erosive gas, brown indicates potassium cyanate, blue indicates carbonyl chloride, and red indicates arsenic cyanide. The power of various types of poison gas bombs is also different, and for this reason, the Japanese army has also deliberately set up a strict authorization system, first of all, the so-called special cigarettes are produced by domestic or foreign production bases, and this production is top secret. It is then handed over to front-line combat units for use, usually with the personal authorization of the commander of the front army. There are also clear provisions on the authorized use, and if the authorized use is Red No. 1, then the combat unit must use Red No. 1, and cannot use Yellow No. 1 or Yellow No. 2.

The Japanese military has always had great enthusiasm for chemical warfare and did not hesitate to invest great manpower and material resources in the study of chemical warfare. As early as 1928, the experimental production of mustard gas began. Six years later, the Japanese were able to produce poison gas at a terrible rate of one ton of Lewiy gas per week, and at the same time, the Japanese army had reached a high level of offensive combat capability with the use of chemical weapons. The Japanese army has a wide variety of poison gas weapons, in addition to all kinds of poison gas bombs and artillery shells, there are mainly poison gas cylinders, poison distribution devices, poison vehicles, poison gas cylinders, and so on.

The most used poison gas by the Japanese army in Chinese mainland is arsenic biphenyl biphenyl poison, which is called "red", and in the use of the Japanese army, the Japanese army requires that it must strive to annihilate the enemy and destroy human witnesses. However, in the previous battles with Han Yunhua's subordinates, the poison gas of the Japanese army almost did not play a role, so there was no talk of destruction certification. However, it is an indisputable fact that one-third of the total ammunition shipped by Japan to China is chemical munitions.

There are three types of units in which the Japanese army conducts gas warfare: field gas units, mortar brigades and infantry temporary smoke units. The field gas unit and mortar brigade are the professional poison gas units of the Japanese army, which can carry out large-scale poison gas attacks, and the infantry temporary smoke unit is a poison gas attack unit temporarily reorganized from the infantry to carry out local poisoning. The poison gas unit equipped by the Sixth Division is a field gas unit and a mortar brigade, of which the field gas unit is the largest in scale, and the logistics and forward combat units add up to a whole wing, and the attack capability is extremely strong.
