On August 11, 1704, the army of Hai Song had completely occupied Shenyang, the most important city of the original Wu family, and in the first 14 days of Hai Song did not encounter the imaginary enemy, Xiao Xuan, as the commander of the Northeast Sea and Land, and the whole army of Hai Song seemed to feel that the victory was going forward.

But it was at this time that the army of the republican army in the Beiping area began to move to Shanhaiguan, which suddenly made Hai Song nervous, and in the face of the republican army's posture of kicking the door, even though Hai Song understood that he was guarding this strategic passage very firmly, but he was well prepared, mobilized a large number of troops, and the fleet of eight warships began to anchor in Bohai Bay.

Although defined as a secondary battlefield, today's battles will surely go down in history. On a runway composed of small stones in the western part of Qinhuangdao, rows of air force fighters and a large group of crew members wore protective clothing to make a final inspection of the fighters.

And on land, twenty kilometers away, the soldiers of the Republican Army moved on the land. It seems that two weeks ago, the artillery of the Hai Song Naval Fleet was impressed, and the troops of the Republican Army were in the form of a small reconnaissance approaching the defensive land laid by the Hai Song Army at Shanhaiguan.

Here you can show the arrogance of an industrial power, with a continuous barbed wire fence. Cement poured fortress. A stronghold is nestled in a stronghold, and this stronghold cannot be broken through at all if it were to be attacked by traditional means.

In the Beijing area, Ren Di has already left at this time and is not here. However, Ren Di's revenge plan is being carried out in an orderly manner.

The sea breeze is very cool, and the sun is enchanting as it falls from the sky. The soldiers on the battleships of Hai Song were busy, two of the eight battleships were 9,000-ton heavy cruisers, three were 5,000-ton destroyers, and the remaining three were 3,000-ton destroyers. This is the era of ironclads. Only Hai Song in the world can build ironclad ships in large quantities, and the firepower of even the lightest destroyer is not something that the fleet on the road can look up to. As for the plane, the bomb load of the aircraft so far hovers around 200 kilograms. Cut wooden structures do not allow planes to dive bomb with a full load. It does not pose a threat of physical destruction to the warship. As for the fish # mine, this thing is too high-tech, the fish # mine technology is now Hai Song's internationally exposed technology is the fish # mine powered by compressed air. The range is between 150 meters and 600 meters, and the launch route is still tortuous due to the influence of the current. To solve this problem, you actually need to add a gyroscope.

But the question of the #Fish-Fish Voyage and the safe throw into the water and then the start, is basically a matter of the republic, after two five-year plans. In these days, it is basically impossible to play with small planes to sink battleships.

But on this theory, in addition to the ironclad ship on the sea, the ironclad ship encountered something disgusting today, when the black pressure plane arrived over this fleet, the crew of the Haisong fleet hurriedly began to shoot at the position of the machine gun array, ushering in rockets with tail flames.

The battleship is not afraid of a low-energy explosion, because the explosion energy exists for a very short time, and the stress of the steel can catch the shock wave of the explosion. Therefore, if the rocket is loaded with explosives, it will not pose the desired threat to the structure of the battleship. However, this time it was not explosives.

Rather, it is a mixture of mustard gas and Lewy gas (called the dew of death in this plane). The rocket hit the superstructure of the battleship, and the sound of "Peng" sputtered out, and the main gun turret of the battleship in this era may be a closed design, but the rapid-fire firepower, especially the anti-aircraft firepower, is not a closed design. As one rocket after another hit the battleship, it was as if insecticide had been sprayed on it, and the insect-sized people who looked at the battleship from the plane suddenly fell silent. Not to mention artillery that fires in the air.

Chemical raid on warships, something that the industrial countries of the 21st century do not bother to do, but almost all naval powers have exercised countermeasures against the surprise attack of warships with chemical weapons. Obviously, Hai Song's fleet did not expect that there would be such a sudden situation today. The poison permeated the entire superstructure, and it was a very fast-acting poisonous gas, and the whole deck was already miserable, like hell, the people on the deck frantically scratched their flesh and skin, the flesh and blood all over their bodies were blurred and eroded, their hair fell out, and then they threw themselves into the sea in despair. As for the damage team, there is nothing to be done about this situation, because the battleship is poison gas, not a fire. And it's contaminated with poisonous gas, and the gas mask can't cover it at all.

The Republican air power raid was divided into three waves, when the first wave solved the defense on the deck, the second wave began to reduce the altitude and try to fire poison gas rockets at the battleship building, as long as one poison gas projectile was fired into the house, then the mission was completed.

When the giant steel weapons of war are unmanned, then it's not a battle between steel battleships and tiny wooden planes, but the Republican Air Force, which uses chemicals to clean up the protein creatures in the steel buildings.

As the fighter pulled across the sea and began to fire precisely at the possible entrance of the battleship, the windows and hatches of the rocket bars allowed a trace of poisonous gas to leak in, and the members of the battleship frantically retreated to the watertight rooms on the lower floor, and firmly closed the door with only a round glass window. It is expected that after this battle, these warships alone will be disinfected. It's no less of a hassle than repairs.

What's more, the last wave of pilots hung on the burning # burning bomb. By the way, put a fire on the battleship. Anyway, no one dared to come out and save it. As soon as the fleet that had been ordered to intercept it arrived at the sea near Shanhaiguan, it was given such a grand reception. Two hundred planes were entertained with four special rockets each, and a raging flame ablaze above the eight battleships.

A huge column of smoke rose on the surface of the sea, as if the fleet was about to be sunk, but in fact it was nothing more than smoke.

This time, when the Republican Army arrived outside the Shanhai Pass, they actually didn't want to seize this position at all, it was precisely Xiao Xuan of Haisong who thought this place was too important for a while, and wanted Ren Di to break the halberd here. After all, the reputation of victory is also very important in the country of Haisong.

When a large number of troops gathered at Shanhaiguan, it also gave the Republican Army the best opportunity to carry out poison gas warfare.

The wind here in Qinhuangdao prevails in the southeast all the year round, and it is a sea and land terrain, so the sea blows to the land during the day, and blows to the ocean at night, fighting poison gas warfare on land, especially preparing to use industrialization to drop a large amount of asphyxiating poison gas, mastering the wind direction is the king, if the wind direction and the terrain are well coordinated, the chemical poison gas is silted up in a zone to maintain the concentration and spread, and the lethality of chemical weapons is no less than that of nuclear bombs. The key to poison gas warfare is to master the microclimate characteristics of the battlefield - this is also Ren Di's specialty before the crossing, but he never thought of using it in the past.

However, in this Shanhaiguan area, the wind direction is stable during the day. And when the sea breeze blows gases that are two or three times heavier than air towards the land, it will be blocked by the Yanshan Mountains and move northward along the mountains. The formation of mountain ranges, and the narrow tube effect of the sea blowing wind direction. Now is the time to gassing this narrow terrain.

Since we want to fight a poison gas war, then we should fight a poison gas war that will be recorded in the textbooks and vigorously recorded in history. Whatever you do, you have to do it with your heart.

When the battleship on the sea, the Republican Army's contaminated poison gas bomb was knocked away. Through the telegram, Xiao Xuan learned about the situation that fire support could not be provided on the sea, and immediately thought of the situation that such a large area of fire support was missing from the front line of the operation.

The glass full of red wine of the "Bing Pong" smashed mercilessly on the floor, and Xiao Xuan, who knew that his fleet had been attacked by a massive chemical weapons airdrop, flushed with anger on his face, and he was annoyed that a week earlier, his immediate boss in the Northeast Asia Command, Bei Liang, had attacked him for wantonly starting chemical warfare. As a result, he was suppressed by his family power, and for so many days, he was controlled by himself with the Liaoning region. And the poison gas storm also retreated as the Republican army showed no signs of attacking.

Just after the observers of Hai Song thought that the Republican Army seemed to weigh the pros and cons to eat this secret loss, they would rather settle the matter, but they did not expect to wait for such a fierce revenge. Thirty percent of the ship's personnel died, and more than 90 percent of the surviving personnel received poison gas injuries of varying severity. When the news came from the fleet, Xiao Xuan's whole body was like thunder. Where is this Ning Shiren, it's just sharpening knives these days.

However, the situation made Xiao Xuan have to return to the present, considering that at this time, the Republican Army suddenly drove away the fleet on the sea and gathered in Qinhuangdao on a large scale. It was very likely that it was a sign of a large-scale surprise attack on the Haisong defense line, Xiao Xuan thought about it for a while, and immediately asked the 15th Army to take a train for reinforcements. However, this command is wrong.

The Republican army's skull-laden items quickly arrived at the front line under the escort of a large group of soldiers, one by one wearing pig-nosed gas masks. When the train arrived at its destination, soldiers wearing plastic gloves quickly lowered the cylinders from the carriages. Since there is going to be a big gas war, the amount of artillery shells that are dropped is far less than the amount of poison gas that is directly released from a canister.

Under the cover of smoke from large patches of burning straw, one by one the canisters were transported to a fixed position lined up for several kilometers. Chlorine # gas is the first generation of poison gas used on the battlefield since the industrial era. It is characterized by being particularly heavy. As the unified time arrived, a row of yellow-green walls of fog appeared on the earth, slowly drifting along the northern land along the sea breeze, and under the blue-blue smoke screen, this eerie yellow-green color. Very low, lying on the ground and moving with the wind.

Later, Hai Song estimated that at least 3,000 tons of chlorine# gas were released in this battle, but in all the Republican army's wartime databases, it is recorded that only 200 tons of chlorine# gas were released at that time. It's desperate to see chlorine # gas lined up on land and pushed forward by the wind, and green is full of gas that can be scraped with a knife all over the airway with a single breath. The Southern Sea Song troops, who had just arrived in this land, saw unprecedented cruelty in their first battle. In the passage of a large expanse of green smoke, the wails of a large number of soldiers whose breath was stirred by knives before death spread throughout the fog, as if they were like ghost fog, and the unrelenting pursuit could not be shaken off. The gas advanced at least forty kilometers. Many soldiers were tired of running, and then drowned in the green of the poison gas, and the green smoke passed through the sky, and the birds were extinct, and there were no insects on the earth.

The Sixteenth Army was exposed to the thickest fog of death head-on, and suffered the most heavy damage. When the wind direction changes at night, the wind direction of the sea blowing on land during the day changes to the wind blowing on land at night. The smoke of the poison gas, which had traveled north along the coast, had finally receded towards the sea. Left behind a land littered with corpses.

For the first time, Hai Song experienced the cruelty of poison gas warfare.
