Because the pursuers were blocked by the coalition forces with plenty of time, in order to hurry no longer hide their whereabouts began to rush in the daytime, tens of thousands of soldiers and more than a hundred trucks were soon discovered by the imperial army, but this has exceeded the combat radius of the imperial air force, the farthest flight distance of the imperial army Dragon bomber combat radius is only 300 kilometers, the position of the coalition forces at this time has long exceeded this distance.

The garrisons of the imperial army occupied the forest area did not dare to go out to fight, and could only watch the coalition troops pass under their noses, but this is not to blame them, the garrison is mainly only responsible for the security of the occupied area, the strength of each town is not very much, the less is only a platoon, and the more is only a regiment, in front of the coalition army of more than 10,000 people and dozens of tanks, two farts dare not let go, where do they dare to take the initiative to go out of the city to fight, so the coalition troops came to the Gallo Mountain Pass smoothly without any danger.

Colonel Griff, the commander of the 779th Regiment of the Imperial Army, who was stationed here at the Gallo Mountain Pass, and Lieutenant Colonel Henry, the commander of the 2nd Battalion of the 24th Regiment of the Norvi Kingdom Army, Ouyang Yu's old friend, and Major Bertlem, the commander of the 1st Battalion of the 147th Regiment of the Principality of Matanzas, used binoculars to observe the coalition troops that were already approaching the city.

The 779th Regiment of the Imperial Army and the 2nd Battalion of the 24th Regiment of the Norvi Kingdom Army, and the 1st Battalion of the 147th Regiment of the Duchy of Matanzas, these three troops were not originally stationed in the Gallo Pass, but the commander of the Fifth Front of the Imperial Army, Grand Duke Philip, issued an order to let these three troops rush to the Gallo Pass day and night before the coalition army.

The military order was like a mountain, and Colonel Griff, the commander of the 779th Regiment, Lieutenant Colonel Henry, the commander of the 2nd Battalion of the 24th Regiment, and Major Bertlem, the commander of the 1st Battalion of the 147th Regiment, had no choice but to stand in front of the coalition troops with a total of more than 2,000 troops.

Recently, within the Imperial Army and the Servant Army, there have been a lot of rumors about this particularly capable Principality of Lucerne coalition army, some say that the soldiers of this coalition army are all tigers and bears, fierce and vicious, and have a super fighting spirit in practice, some say that this coalition army is particularly capable of fighting because it is equipped with magic weapons in ancient times, and some are that the soldiers of this coalition army are actually not humans, but puppets made with ancient construction technology, and all kinds of rumors represent only one sentence, that is, this coalition army is not easy to mess with.

The 779th Regiment of the Imperial Army is a newly formed unit, and it has not been long since it came to the Eastern Continent, and it is basically all recruits from top to bottom, and even many officers at the platoon level are rookies who have just come out of the military academy, and they all think that they can fight ten of them with one person.

The 2nd Battalion of the 24th Regiment of the Norvi Kingdom Army and the 1st Battalion of the 147th Regiment of the Duchy of Matanzas Army were all arranged to rest in the rear because of the defeat with Ouyang Yu's army, and most of the troops were newly recruited supplementary soldiers, and the combat effectiveness of these three armies was really worrying, but the Grand Duke of Philip could only find these three formed troops near the mountain pass, so he could only send them over, and he himself personally led 100,000 pursuers to chase behind.

Colonel Griff had the highest status and rank, so he naturally became the commander of these three forces, and Colonel Griff put down his binoculars and asked Lieutenant Colonel Henry and Major Bertlem beside him, "Is there any good way to deal with the enemy army?"

"It's ....... Lieutenant Colonel Henry and Major Bertlem glanced at each other, both in terms of numbers and equipment, they were much worse than the coalition forces, especially the lack of anti-tank equipment, which made the two of them lack confidence, and they couldn't think of any good way except to fight in a daze.

Colonel Griff just casually asked and didn't expect the two of them to really have any good solutions, in fact, he didn't have a good way to deal with it in his heart, so he could only rely on the fortress to fight with human lives, hoping that the ancient fortress under his feet could withstand the cannonballs of the coalition army.

While Colonel Griff and the three were observing the coalition forces, Ouyang Yu and Brigadier General Louis were also observing the fortress, and Brigadier General Louis asked Ouyang Yu beside him, "Do you have any good way to break through the fortress quickly?"

Ouyang Yu put down the binoculars and shook his head, this is the first time she has seen such a thing as an ancient fortress today, where will there be any good way, she can only tentatively see the reaction of the defenders first.

Under Ouyang Yu's order, fifty-six mountains and field artillery were aimed at the ancient fortress wall.

"Fire!"

"Boom, boom, boom......!"

One by one, the cannonballs fell accurately on the wall of the fortress with a whistling sound, the ancient city walls were built with a meter square of bluestone, and they were reinforced with magic, the damage of seventy-six mm shells to this kind of city wall was really limited, and the shelling stopped after ten minutes, Ouyang Yu held a telescope to check the situation, except for some flames caused by the explosion, there was almost no damage on the city wall, and the defenders had already evacuated the city wall before the shelling, so the shelling just now did not have any gain except for wasting a bunch of shells.

"That's a problem. ”

The strong fortress wall looks like it can only be blown up with large-caliber heavy artillery, but the price of a heavy cannon is expensive, and it can't be taken away when it is used up, it must be blown up, even if Ouyang Yu has money, it will not be so extravagant, she quickly used her brain to come up with a quick and feasible way.

Compared with the distressed Ouyang Yu, Colonel Griff and the other three of the Imperial Army cheered after checking the situation of the fortress city wall, the strong ancient city wall has become a moat for the coalition army, if the coalition army has no way to deal with the city wall, the three of them will have the confidence to defend until Grand Duke Philip comes with a large army, and then they will become the heroes who will assist in the elimination of this coalition army, and the addition of officials to the knighthood is just around the corner.

Ouyang Yu couldn't think of any good way after thinking for a long time, so he had to order the artillery unit to shell the gate of the fortress wall again, generally speaking, the city gate is a weak point, but Colonel Griff and the three laughed, because the city gate had already been blocked by them with bricks and stones, even if the city gate was blown to pieces, it would be useless.

The result of the fact is also the same, when Ouyang Yu's artillery wasted half a day to blast the iron city gate, only to find that the back of the city gate was full of bricks and stones, blocking the city gate to death, not to mention people, even a mouse is difficult to climb over, she gave up the idea of attacking from the city gate, and the first day of the siege passed in Ouyang Yu's depression.

At night, Ouyang Yu sent sappers to quietly lurk under the fortress wall, wanting to bury five hundred kilograms of explosives to blow up the city wall, but was found by the imperial army on the city wall halfway through, resulting in a failure, although the half of the explosives that had been planted were detonated, but the strong fortress city wall was damaged to a certain extent but still standing, Colonel Griff and the three were blown out of a cold sweat, fortunately, the fortress city wall was strong, and it was discovered early, otherwise the consequences would be unimaginable, with such an example, Colonel Griff strengthened the night patrol realm, so that Ouyang Yu no longer had the opportunity to attack at night。

After a few tosses, Ouyang Yu had no moves, so he could only fight with his life, from the third day, the coalition troops were divided into three parts to attack the fortress in turn, and the soldiers cut down trees from around the fortress to make a lot of long ladders, and the walls of the fortress were as high as twenty meters, and they couldn't climb up at all if they weren't long.

The sound of explosions and gunfire resounded on the ancient fortress, and the soldiers of the new era were like their predecessors hundreds of years ago, carrying long ladders for siege warfare, and the soldiers of Ouyang Yu's army were in the lead, and they were distributed a large number of Suomi submachine guns and grenades, and there were machine guns and precision shooters in the distance, braving the dense light bullets fired from the city to launch an attack.

A soldier of Ouyang Yujun held a Suomi submachine gun in his right hand, held the ladder in his left hand, and climbed quickly with his feet, but when he was about to go up to the city wall, the ladder was pushed down by an imperial soldier, and the Ouyang Yujun soldier fell to the ground screaming together with several soldiers below, and the imperial soldier who had pushed down the ladder just now was immediately shot in the head by Ouyang Yujun's accurate shooter.

"Mortars block the walls for me, shoot all the shells out as fast as possible, machine guns and precision shooters pay attention to the priority of attacking those who want to knock down the ladder!"

The heavy casualties in the attack made Ouyang Yu feel very distressed, but in the absence of heavy artillery, he could only fight with his life.
