Three quarters of an hour later, the soldiers came to report that all twelve frogmen had returned safely, and Bailiyan immediately ordered the whole city to wear gas masks, and a quarter of an hour later began to gas attack.

With the launch of six red signal flares, the artillery positions ten miles from the port retreated and camouflaged during the day, and the soldiers wore gas masks and quickly turned to the battle positions, and the shelling began

"Pay attention to the artillery, prepare, and release!"

With a single gunshot, dozens of guns roared and sprayed fire snakes, and a projectile filled with chlorine liquid flew towards the target, either hitting the hull of the ship or hitting the deck, and the moment it exploded, yellow death smoke rose up.

The armpit officers and men who were about to flee for their lives could not avoid it, inhaled chlorine gas, and the screams and shouts were incessant, and countless people were killed and fell to the ground in a few minutes or ten. The war has reached this point, to the point where everything is done and unscrupulous.

Looking at the miserable scene from afar, Bai Liyan felt heavy, and he was thinking about what would happen if it was him on the other side, his robe.

But he knows that this is a war, a war between two species and civilizations, either you die or I die. Kindness to the enemy is cruelty to himself, and he has no choice.

The shelling continued until dawn and dusk, and after more than 2,000 rounds of chlorine bombs were fired, Bailiyan immediately ordered the shelling to stop, because the whole port was filled with yellow smoke, and the wind was northwesterly, which was favorable for the spread of chlorine gas to the open sea.

However, chlorine will be diluted by seawater, and the process of low tide and high tide will wash high chlorine seawater into the beach outside the port, which will cause certain environmental damage to the local area in a short period of time, and even cause harm to people.

After dawn, the four ironclad ships had tilted, except for the shrill stretching out of the twisted hull, it was almost impossible to hear the screaming and snoring of the armpit people, and the explosion of ammunition explosions.

When the sky was completely brightened and the situation was clear, the armpit detachment flotilla cruising more than ten miles north of the four ironclad ships sent a clipper ship of about 7,000 stones, and under the cover of the detachment fleet, quickly approached the four ironclad ships that had been slowly sinking into the sea in an inclined formation.

At this moment, the sea is full of armpit corpses, and it is not an exaggeration to say that there are rivers of blood flowing and tens of thousands of floating corpses.

In the face of chlorine damage, the armpit man was unrecognizable and miserable, and the port and outside were almost filled with corpses, drifting like lonely ghosts as the tide flowed.

The clipper that tried to approach fished out a few survivors, and was forced to turn around and flee because of the Xian artillery, and an hour later, the detachment also sailed north to join the main fleet.

Bailiyan immediately sent people out of the city to bring those armpit people who were still alive ashore, and at the same time took photographs and photographic materials as internal references, leaving this testimony for history for historiography and military research.

Xu is loss of four ironclad ships was too shocking, the armpit main fleet began to retreat, turned around to the west and slowly sailed away, if it was not for fraud, it should have been frightened by the terrifying strength of the Xian army.

Bailiyan hurriedly sent a Hongling urgent letter to Sangbei, reminding Zhou Kong and Ye Xin to beware of the movement of the armpit landing force entrenched in Jiaoping County. At the same time, he sent a good news to Chenling and reported the results.

On the morning of the same day, more than 480 people with armpit eyes were captured and fished out, and more than 4,700 corpses were counted on the sea surface and on the deck of the ship with the naked eye, and many more were trapped and killed in the canned ship.

In the afternoon, the two ironclad ships completely capsized and sank to the bottom of the harbor, but the command station and several masts were still exposed.

The other two, one of which managed to crash into the harbor, leaned on the stone steps of the berth, leaning and emitting thick smoke, and from time to time there were still violent ammunition explosions.

The other ship was slanted into the sea at an angle of 35 degrees, only half of it sank, and then it was not sinking, and Bailiyan knew that it must be the armpit people who also studied the watertight cabin and closed the watertight door in time.

In the evening, Bailiyan set up a banquet to celebrate the twelve heroes who risked their lives last night, due to the destruction of the infrastructure in the city, the evacuation of the rural population outside the city, the food supply is not very rich, it is not easy to supply small stoves or anything, it is not easy to supply from other counties, more are canned food and some vegetables. At the same time, Bailiyan also began to consider setting up a medal system to commend and praise meritorious soldiers.

Affected by the defeat in the Guangxin naval battle, on the ninth day of November, more than 28,000 people entrenched on the Bund of Jiaoping County, Mianshui City, Sangbei County, and the armpit landing force of the Mianshui River on the east side quickly withdrew to the sea.

The armpit men who landed in Jiaoping County were 30,000 small, and their warships were close to the coast two miles away, and their heavy naval guns and cannons could reach 20 miles, and the range of other medium-caliber cannon guns was also 12 to 20 miles.

If rapid-fire warships are mobilized, most of their conventional ship-based rapid-fire cannons have a range of between 15 and 18 miles, and the firepower density has an absolute advantage.

The 645 type 36-pound cannon and the 645 model 72-pound heavy gun that the Xian Army gave priority to renovating have a range of 20 miles when using the extended-range charge of the medicine pack, and the range of the two types after upgrading is equivalent to that before the upgrade, if the metal cartridge is used, the range is only 16 to 18 miles, and the range is not as good as before.

In order to carry out effective firepower strikes against enemy troops landing on the shore, both types of artillery must be within 18 to 15 miles to ensure the accuracy and destructiveness of the dropped shells, and this distance is precisely within the limit range of the axillary fleet.

Of course, at the beginning of the design, if the charge is increased, the firing range can be increased, but the disadvantages are more obvious than the advantages brought by the firing range.

First of all, both types of guns use brass metal cartridges, increasing the propellant capacity, but also increasing the circumference and weight of the cartridge, the result of the increase in range is a decrease in the firing rate, even if the cartridge is fired, only the metal warhead is loaded, the weight of the cartridge increases, the gunner's labor will still increase, and the efficiency is not cost-effective.

The second is that the performance of artillery steel itself has reached its limit, and the design safety redundancy cannot be abandoned to increase the firing range.

Although the upgraded and modified artillery of the Xianjun Army uses platinum-based copper-nickel-iron-based alloy and casing self-tightening technology, the old cannon barrel itself has not been forged and heat treated, and has not exerted the excellent performance of the cannon steel, and the embedded rifled tube inside is not enough to greatly improve the performance, so although the material is good, the performance has not been excavated and developed in essence.

Third, the power of double-base gunpowder has increased significantly, but the use of brass cartridges occupies the space for the increase of gunpowder, so in the case of the total amount of double-base propellant decreased, the range remained unchanged, and the range was actually increased, but because the cartridge squeezed the space of gunpowder, the increase in performance was not obvious.

Fourth, the Xianjun artillery was light in weight, while the axillary artillery with similar performance was generally 20 percent heavier than the Xianjun artillery, or even 30 percent, and the charge was three times that of the Xian army.

Finally, the double-base gunpowder nitrocellulose and passivated nitroglycerin consumed by the artillery, the former requires a large amount of cotton, the latter requires a large amount of chemical raw materials, nitroglycerin production seriously cannot keep up with nitrocellulose, if the ammunition is too large, the consumption is too much, and finally only nitrocellulose is fired, and in the case that the artillery has been upgraded and the volume of the charge is reduced, the firing range will inevitably be reduced.

Therefore, the range and caliber are the best match made by weighing the industrial system and logistics, and they are helpless choices under specific technical conditions.

The two heavy artillery brigades and one cannon brigade deployed in Sangbei County, and a mixed artillery cannon brigade with Ye Xin's heavy artillery cannon were only 216 guns in total, and the ammunition could not be enough, and it was too difficult to suppress the fire of dozens of ships with thousands of guns at sea.

Moreover, this is a moving target, not a fixed target, and the cannon must be pushed down within ten miles of direct aiming, so a large number of infantry is required to cover, and at the same time all exposed to enemy fire.

Even if he can kill a few or a dozen of his ships, the Xian army will lose dozens of artillery, and at the same time, the dog jumps under the wall, the infantry fights, the Xian army does not have an advantage in numbers and weapons, and it is helpless to let him escape.

On 12 November, after 10 consecutive days of boarding and searching and inspecting, Bai Liyan boarded the armpit ironclad canning ship that was rushing to the harbor and began an in-depth investigation of its technical performance, hull structure, weapons and equipment, and all useful information.

Therefore, based on the above information, its industrial manufacturing capacity is reversed, and the follow-up strategic policy is formulated for the next long-term war of resistance.

As expected, the canned ironclad ship did use a double-shell design, with two layers of armor inside and outside, and in the middle were quenched solid projectiles of various sizes, and the total armor defense thickness was equivalent to 470 millimeters of ordinary homogeneous steel, but the actual thickness was only 327 millimeters, and the inner shell armor plate was only 70 millimeters, and the 187 millimeters of space in the middle of the two shells were filled with quenched carbon steel solid pellets, and the defense effect was peculiar.

The frequent firing of howitzers on the ship before made Bai Liyan realize that the armpit people used some kind of reentry mechanism to counteract the recoil, otherwise it would be impossible to use fixed guns on the ship.

Sure enough, the axillary man used a spring re-entry mechanism to automatically reset the gun, and the gun unsurprisingly used a wedge-shaped bolt door, the cartridge and the copper ring were closed, and the rifling of the gun was also clearly visible, and a series of previous technical conjectures have now been verified.

Spring re-entry and hydraulic re-entry, the former has simple technology and simple maintenance, but the recovery effect is slightly poor, and the spring needs to be replaced after long-term aging fatigue, and it will also break and fail under intense use, and even the spring can break in harsh environments.

The hydraulic re-entry mechanism has higher requirements for the material of the hydraulic cylinder, and needs to be equipped with hydraulic oil and cylinder and piston polishing and electroplating, and the required supporting industries and technical standards are very high, so the spring re-entry is easier to achieve technically.

But it's not that the armpit people can't achieve a hydraulic re-entry structure, and Bailiyan is shocked to find that they are extremely smart.
