The battle for the fortress of Gallo Mountain Pass continued, and after a morning of storming, Ouyang Yu's army left hundreds of corpses but still did not attack the city wall, and after taking away the wounded comrades, the coalition soldiers who replaced them began to attack.

With the experience of siege in the morning, the artillerymen under Ouyang Yu, especially the mortar crews, used a large number of high-ballistic mortars to block the city as much as possible, killing and injuring the enemy troops on the city to provide cover for the attacking coalition soldiers.

The soldiers of the coalition army under the city launched a heroic attack under the cover of artillery fire, and the soldiers of the imperial army and the servant army on the city head braved the artillery fire to fight back desperately, and the light bullets fired hit the soldiers of the coalition army from time to time, but under the strong firepower of Ouyang Yu's army, the imperial army and the servant army on the city head were suppressed, and the coalition army rushed under the city wall after paying a certain price.

"Throw it at me, burn these hillbillies!"

Colonel Griff, who commanded the battle in the rain of bullets at the head of the city, had his soldiers make a large number of primitive incendiary bombs between battles, which were commonly used by the defenders of the city in ancient times in another world, and weapons that were once obsolete after hundreds of years are now reappearing on the battlefield.

This primitive incendiary shell uses a clay pot, which is filled with black oil (oil) and filled with some magic crystal powder, which can increase the splashing effect, the mouth of the can is sealed by a cloth strip, and after ignition, it is dropped, the clay pot is broken, and the black oil inside is ignited, and the ignited magic crystal powder will cause a slight explosion, so that the burning black oil can spread to a greater distance.

Hundreds of incendiary bombs were dropped, and the coalition soldiers below were screaming and screaming, and dozens of ladders fell into a sea of fire, and the remaining coalition soldiers did not dare to approach because of the flames burning under the city walls, and the second attack ended in a hurry, and the number of coalition troops burned to death exceeded two hundred.

"Hit, blow them up with shells!"

Ouyang Yu, who was holding his breath in his heart, had no choice but to use cannonballs to vent his anger, but the cunning Colonel Griff had already ordered the soldiers to withdraw from the city, and Ouyang Yu's shelling was ineffective.

Brigadier General Louis suspended the attack before he could come up with a good solution, and any further fight would only add unnecessary casualties.

Ouyang Yu walked back and forth like a wounded she-wolf, she cursed the commander of the Imperial Army countless times in her heart, but the curse was useless, she had to come up with a way to eliminate the enemy cowering in the fortress as soon as possible, thinking about it, Ouyang Yu set her sights on the war system, hoping to find a way to defeat the enemy in it, in the face of time and a lot of lives, she didn't care about spending money.

The navy and air force directly skipped, tanks, armored vehicles were also ignored, heavy artillery, this can be considered, but more than 200 kilograms of explosives have not blown up the collapsed city wall, and the general large-caliber heavy artillery may not help, and it is possible to use super heavy artillery of more than 200 mm.

Ouyang Yu looked at several heavy artillery pieces from various countries and finally selected, the 420 mm Great Berta Super Heavy Cannon used by Germany to capture the Scorching Sun Fortress in World War I.

Already at the beginning of the 20th century, the General Staff of the German Army demanded the design of an energy system for the capture of fortresses. The experience of the Japanese capture of Port Arthur proved that heavy artillery was indispensable for attacking the fortress. This heavy artillery was supposed to be a mortar with a short barrel, capable of firing at a high angle, allowing the shells to fall on the roof of the fort while hitting a specific target with considerable accuracy. The Germans entrusted this task to Philippz Krupp, the son of Alfred Krupp, the "King of Cannons", and demanded absolute secrecy. In 1909, Fillitz secretly developed a giant mortar gun, named after Fillitz's mother, called the "Big Belta" gun. This type of gun, together with the gun truck, weighs 120 tons and can fire nearly 1 ton of shells to targets up to 14.5 kilometers away. Each shell used up nearly 200 kilograms of propellant and required more than 200 gunners. It can also fire armor-piercing shells equipped with a delayed fuse, causing the shell to explode after penetrating the target. However, it was so cumbersome that it had to be disassembled and hauled by a locomotive. It was also necessary to lay a special track in order to transport it to the gun mount. At the same time, due to the huge recoil it generates when fired, it is necessary to pour a concrete base several meters deep and blow it up as it moves. It took 6 hours just to place the gun emplacement. Prior to that, the largest of the known various artillery pieces were 343-mm naval guns of British caliber and 279-mm stationary howitzers of coastal artillery. But none of them can compare to the Great Berta cannon. Over the next four years, Fülitz Krupp continued to develop a cannon that could be divided into several parts and suitable for road transport. In February 1914, the prototype was successfully produced and tested at the Kummersdorf test site, and the Kaiser, who was invited to the scene to watch, was very satisfied. However, experiments with steam engines, gasoline motors and even horse-drawn vehicles on the road have shown that further improvements are needed. The improvements were scheduled to be completed on October 1, 1914. By the time the war broke out in August 1914, Krupp had produced five 420 mm railway cannons and two road cannons.

The battle situation was urgent, and Ouyang Yu immediately purchased four large Berta super heavy cannons, as well as the related operators, all of which cost more than 300,000 silver coins, and the four cannons alone cost 250,000.

After purchasing super heavy artillery, it is not possible to shell immediately, and it will take six to seven hours of preparation time, and after everything is ready, a day will pass, and the impact point will not be observed at night, so it will be changed to the next day.

The next day, it was just dawn, the launch position of the big Berta super heavy artillery was already busy, Ouyang Yu accompanied Brigadier General Louis to the launch position to watch the launch together, whether Ouyang Yu came out of the weapons and equipment, Brigadier General Louis has long been surprised, everyone has their own secrets, Brigadier Louis does not like to listen to other people's secrets.

Princess Roni, who came with her, was secretly frightened, the majestic posture of the big Berta super heavy cannon shocked her, this kind of steel monster weighing one hundred and twenty tons is not impossible to manufacture with the technology and financial resources of the Phoenix Empire, but each one requires astronomical money, and it is time-consuming and laborious, so the imperial army is not equipped with tired super cannons, and the most incomprehensible thing for Princess Roni is that before yesterday, Ouyang Yujun obviously did not have these four super cannons, and four suddenly appeared overnight, where did these super cannons come fromWho created it? Doubts filled Princess Roni's brain.

After intense preparations, the launch preparations were completed, and Ouyang Yu couldn't wait to give the launch order.

"Boom......!"

The deafening sound of artillery could be heard even from dozens of kilometers away, and the coalition soldiers who were eating breakfast looked in the direction from which the shelling came.

After flying in the air for more than ten seconds, the huge cannonball smashed into the ancient fortress under the action of gravity, although it did not hit the thick city wall, but it also hit a barracks built of stone behind the city wall, the armor-piercing bullet weighing a ton easily penetrated the stone roof, and then drilled into the ground for more than ten meters before it exploded with a bang, this barracks and the Imperial soldiers inside turned into powder, and the huge explosion left a large crater on the ground more than ten meters deep and more than twenty meters in diameter.

Colonel Griff, who had just gotten up, was startled by the loud explosion and vibration, and hurried out of his place to check the reason, "What happened?!" he grabbed a soldier and asked loudly, but the soldier didn't know what was going on, just shook his head vigorously, Colonel Griff cursed rubbish, left the soldier and ran in the direction where the explosion came from.

When Colonel Griff had just arrived at the huge crater that was still emitting green smoke, the second corrected shell landed on the fortress wall, although the bluestone city wall had been reinforced by magic, it was still pierced like tofu in the face of the 420 mm armor-piercing shell, and the shell that had penetrated into the city wall exploded in the narrow space, and the wall of 20 meters high and 10 meters wide collapsed with a bang.

"Launch, launch! blow up those bitch-of-bitch imperial pigs!"

After seeing the actual effect of the super cannon, Brigadier General Louis waved his arms excitedly and asked Ouyang Yujun's gunners to shoot more shells.

Two of the four 420 mm armor-piercing shells hit the city wall, but even if only two of them blew down a section of the wall, the coalition soldiers shouted with the same excitement as Brigadier General Louis when they saw the wall that had stopped them for three days and pay a heavy casualties to be blown down, venting the anger in their hearts for the past few days.

On the Imperial side, on the other hand, the earth-shattering shelling and the collapsed walls had caused the morale of the soldiers to plummet, and Colonel Griff hurriedly ordered the soldiers to go up the walls, knowing that the attack of the coalition forces would be launched immediately.

The interval between the firing of the Great Berta Super Heavy Cannon is very long, about an hour to fire a shell, with the Super Heavy Artillery Brigadier General Louis is not in a hurry, the pursuing Imperial Army will take two days to arrive, and under the bombardment of the Great Berta Super Heavy Artillery, the fortress can definitely be taken today, he hopes to bombard a few more cannons, and completely destroy the city wall to reduce the casualties of the coalition forces.

From 6 a.m. to 12 p.m., four large Belta super-heavy guns fired a total of seven rounds, and sixteen of the twenty-one shells hit the city wall, causing the wall to collapse several sections more than 100 meters long, and the attack was no longer without any problems.

At half past twelve o'clock in the afternoon, Ouyang Yu's army's numerous mountains and field artillery began to exert their might, and the coalition army launched a general attack, without the blocking of the city wall, tens of thousands of wolf-like and tiger-like coalition soldiers entered a no-man's land, crossed the collapsed city wall and launched a fierce melee battle with the defenders.
