The heavy artillery battalion and field artillery battalion of the Yunnan army opened fire, but their target was not the Japanese army on the hill, but the position of the Japanese artillery observed by the observation post, which was suppressing artillery fire. Pen, fun, and www.biquge.info

"Tom tom tom" This is the mortar sounded, and this is the small hill occupied by the Japanese army.

The weapons of the Dian army are very distinctive.

Because a considerable part of their weapons were made in France, they had exchanged the fine tobacco produced in Yunnan through French-controlled Indochina and the French bordering Yunnan.

And the French-made mortars they used were the farthest and most accurate mortars in the world, so it was completely enough to suppress the Japanese troops on that hill with mortars.

After 20 minutes of artillery fire, the soldiers of the Yunnan army shouted "kill, kill, kill" and launched a charge on the trenches occupied by the Japanese.

Because the area on the top of Yuwang Mountain is too small, and it is a place where the firepower of both sides is concentrated, the more troops placed in the trenches by all sides will increase the casualties, but the number of people is less but more ammunition, and the bullets and grenades of each person in the trenches of the soldiers of the Yunnan army are in boxes.

Compared with the rest of the Chinese army in terms of light weapons, the Japanese army has an advantage over rifles and grenadiers, but compared with the Dian army, it is really half a catty and eight taels, because the Dian army also has it.

Therefore, under the deliberate onslaught of the Yunnan army, although there was strafing fire from the Japanese light machine guns, after being knocked out by the grenadiers of the Yunnan army, the resistance was much weaker.

The rear support artillery fire was temporarily suppressed by the two artillery battalions of the Dian army, and the two trenches dug by the Japanese army in front of the hill were quickly captured by the Dian army.

But this did not mean that the Japanese army was not prepared for the counterattack of the Dian army, and dozens of Japanese soldiers wearing gas masks soon came out of the bunkers on the hill.

They brought out the large barrels from the bunkers, unscrewed the lids, and the yellow smoke gathered into patches of smoke and drifted towards the attacking Dian soldiers under the blowing of the wind.

"What's that?" The bearded brigade commander who commanded in the back soon spotted the thick yellow mist that hung in the air.

"It's poison gas!" Huo Xiaoshan, who was following the bearded brigade commander, shouted urgently.

This is the first time Huo Xiaoshan has seen poison gas, although he has not seen it, but he has heard veterans like Dung Qiuzi who fought in the Battle of Songhu say that because the Japanese army used poison gas in the Battle of Songhu.

The bearded brigade commander, as a high-ranking general, obviously remembered what poison gas was, and their Yunnan army even had the establishment of a chemical defense company, and the gas masks were also bought from the French.

But who would have thought that the Japanese army would use poison gas at this time, and there was no preparation for this at all, and everyone's faces changed for a while.

During the poison gas war during World War I, there was a human tragedy in which tens of thousands of people were poisoned to death, so it was later banned by the belligerents in the situation of international conventions.

But the Japanese don't care about this, they are already crazy, what they think is what if I use it, as long as I can win this war soon, what can you do to the international community? International trials only work for the weak!

Seeing that the soldiers of the Yunnan army who were rushing forward were about to touch the edge of the yellow mist, a miracle happened, and the yellow poisonous mist actually drifted towards the Japanese position!

"The wind has changed! The wind has changed! The soldiers of the quartermaster department were all following behind Huo Xiaoshan and the bearded brigade commander, shouting excitedly.

Yes, the direction of the wind has changed!

The direction of the wind not only changed, but it became the opposite, but it drifted towards the Japanese position at a faster speed!

Soon the Japanese positions were shrouded in the yellow smoke. The Japanese army in the yellow fog can be seen to be in chaos with the naked eye.

Everyone was in a hurry to find gas masks, but they were also like the unprepared Dian army at the beginning, how could they expect that the wind would suddenly become reversed, and it was too late to cling to it when it came.

Suddenly, I heard the coughing of the Japanese soldiers in the smoke, and some people began to roll on the ground.

"You can't live if you've done your own iniquity! Blow the trumpet and let the troops take the opportunity to rush forward! The bearded brigade commander ordered.

The military horn of "Da Da Da" sounded, and the soldiers of the Dian Army who were impacting in front naturally understood what was going on.

How could the Japanese army, which had been dizzy in the smoke, have the strength to fight back?

The dense gunfire of the Dian army rang out, and the Japanese troops in the yellow fog had no bullets to fight back.

By the time the wind blew the yellow mist through the positions occupied by the Japanese army, the ensuing Dian army had completely occupied the positions.

Then, with the Burmese knife in his hand, he chopped the Japanese soldiers who were rolling and foaming at the ground to the ground.

The commander of the 10th Division of the Japanese Army, Ryosuke Isoya, miscalculated.

Each division of the Japanese army has a special chemical weapons unit, which is always on standby when marching with the large force.

The poison gases they release generally consist of 70 percent of the smoke and another 30 percent of the gas.

When he learned that the Chinese army was attacking and the wind was right for gas warfare, a despicable order was given.

Unleash poison gas on the Chinese army, then launch an attack and take the opportunity to occupy the entire Yuwang Mountain.

But to be honest, compared to the Chinese army, the Japanese army's chemical weapons are really killing weapons, but they are not advanced chemical weapons warfare methods in the world.

This method of releasing smoke with barreled poison gas is only at the level of the First World War, and there is no countermeasure for the sudden change in the direction of the wind, but instead poisons all the soldiers on his side.

The quartermaster everyone followed behind the bearded brigade commander and rushed to the position occupied by the Japanese army, and saw that the position was full of Japanese soldiers who had lost their combat ability after being poisoned and were hacked to death by the soldiers of the Yunnan army.

Everyone is on guard, and in the future, they really have to guard against this despicable trick of the little devil, if it is not for the Bodhisattva to bless the sudden change in the direction of the wind today, then it is us Chinese who roll on the ground and be poked to death today.

At this time, they finally stood on the hill on the side of Yuwang Mountain as victors, but everyone in the quartermaster department regretted it.

Although we participated in the battle, they didn't let us rush to the front, but followed behind the brigade leader, and now we haven't even fired a single shot!

I could see that under the blowing of the wind, the poisonous yellow mist was getting fainter and fader until it finally dissipated into nothingness.

There are still Japanese troops retreating from the slope in embarrassment, and there are also soldiers of the Yunnan army who are rushing to the front are struggling to pursue downward, and they have reached the foot of the mountain, and beyond that there is a green wheat field.

"Blow the trumpet, rush down, and expand the results!" The bearded brigade commander suddenly ordered.

The sound of the military horn of "Da Da Da" started again, and the soldiers of the quartermaster department were overjoyed, there was still a battle, one by one, Huo Xiaoshan led the girl and ran down the mountain, they are the last echelon of this attack, and if they don't compete for the first place at this time, when will they wait? !
