The battle lasted from late night to dawn, and from early morning to mid-morning, when hordes of Federation fighters finally appeared in the southeast sky, accompanied by a faintly recognizable flying fleet. The arrival of their own aviation units gave hope to the troubled defenders of Aocheng. Judging from the scene, the Norman army that attacked the city was like a rainbow, and it was only a matter of time before they won, but in fact, they mainly relied on sharp artillery fire, plus they had the initiative on the battlefield, and they were able to calmly deploy troops and sacrifice various tactics to enter the city with a non-dominant force. As long as the Union forces were able to regain air supremacy and suppress the Norman artillery, the defenders could take advantage of the home field and launch a counterattack to redeem the defeat, drive the Norman army out of the city, or even annihilate it on the spot – at least theoretically.

Weiss led his troops to garrison the factory area, which had already survived three waves of Norman offensives by this time. Seeing that the Norman soldiers took the initiative to retreat, he knew that the enemy must have a rear, so he hurriedly ordered his brothers to move from the battle fortifications to the anti-artillery bunkers. Sure enough, the Normans soon launched a round of heavy shelling of the factory, covering every building and every piece of ruins, even the horns. Even if you are in the deep sewers, you can feel the terrible power of the enemy's artillery fire, not to mention that not all the anti-shelling bunkers are located underground, and some of them only borrow water tanks, warehouses and other facilities according to local conditions, and in the face of shelling of this scale and intensity, the defending officers and men will inevitably suffer casualties. Thankfully, as the planes of the Union Army approached the city, the Norman warships, which were shelling the ground, immediately shifted their targets. They were seen to form an almost circular battle array, moving slowly to the southeast, which meant that they chose to meet rather than retreat.

At the beginning of the confrontation, the sky was filled with the guns of Norman battleships, guns and machine guns of various calibers, holding up a huge umbrella above the fleet. Fragments of artillery shells and bullets can easily shred the fragile bodies of the Union fighters, swatting them like flies, and the Union fighters are not in a hurry to attack, they hover high in the air, observing the enemy situation and seizing opportunities. Once the timing is right, it swoops down from the sky like a boobies fishing. After the tempering of the war, the pilots of the Federation Army became more and more proficient in technology, and the coordination became more and more tacit, as long as the Norman battleship was targeted by an entire flying team, few could avoid the attack.

Bombs equipped with triggering fuses hit the Norman battleships one after another, and the violent explosions came one after another, and the Norman fleet, which had just been imposing and neatly formed, was now like a group of ships sailing with difficulty in the stormy seas, and the flames of the explosion continued to impact and erode their hulls, making them tremble and swing, and change the direction of their voyage intentionally or unintentionally. When the smoke cleared in the wind, the huge steel warships also showed a lot of scars, some still standing proudly, and some looked overwhelmed.

On the ground, the troops on both sides invariably chose to "wait and see." After the Norman shelling paused, Weiss and his soldiers poked their heads out of their bunkers, watching the battle in the air while watching the movement of enemy soldiers. In this fierce battle, both sides used all their strength, with an attitude of not giving an inch, in comparison, the Federal Army fighter unit is more skilled, with the weak body that was not favored by the public, to create more trouble than expected for the enemy warship group, but after all, they are still not strong enough, they can use a storm of attacks to beat the enemy ships all over the body, black smoke billowing out, but it is difficult to give the opponent a fatal blow. The Norman warships in the sky, whether they are typical Norman lines or familiar Wessex styles, seem to have only the power to parry, but they have vigorous vitality. Some of them were hit by more than a dozen bombs, and several times they caught fire, most of the guns on the ship were destroyed, and the defensive firepower changed from a passionate shout to a low moan, but they did not sink or explode, and continued to fly in the air. Hundreds of Federation fighters attacked in several echelons, destroying only one Norman light warship, forcing a forced landing of one medium and two light warships. As the Union forces struggled to adapt to the Normans' tactics, the Normans also gained experience and found countermeasures in battle, and they showed great learning and adaptability on all fronts. Because of this, more and more planes of the Union Army are entering the battle, but the results achieved are drastically decreasing.

Looking up, Weiss observed, pondered. Suddenly, he saw the red-fuselage, white-winged Federation fighter, the one-of-a-kind "Red and White Knight", which was undoubtedly Nicolas Leboyd's mount. He got his wish and won the opportunity to soar into the sky, becoming an "unconventional" flight commander. Under his leadership, the Coalition's warhawks launched a fierce attack on the largest Norman warship, and in a short time, the middle of the battleship was hit by bombs one after another, explosions came one after another, flames rose into the air, and the back half of the hull was surrounded by dense gunsmoke. Then, the ship's explosion began, and after another, the battleship's flight attitude finally changed, its bow was raised, but its flight altitude continued to decrease, and the rate of descent was significantly faster, which meant that its power system was severely damaged. Without sufficient levitation power, the flying monster made of massive steel had to succumb to gravity and eventually crashed to the ground.

In the loud roar, the whole city trembled, and many damaged buildings were directly collapsed. At the fall of the battleship, billowing smoke and dust caused a small man-made sandstorm. Amazingly, the behemoth with a huge amount of fuel and ammunition crashed to the ground without an earth-shattering explosion, which means it can also serve as a fortress in the rest of the battle. As for whether to help the Norman army or be counterattacked by the defenders, it depends on which ground forces can seize the opportunity - under such a violent impact that is close to crashing, the ship's personnel are not killed or wounded, and it is obviously unrealistic to expect them to go into battle immediately.

In the sky, the Union fighters who had completed the bomb dropping did not attempt to harass the Norman battleship with their weak machine-gun fire, and they turned around very decisively, giving up their attack position to the fighters and fleets that arrived on the battlefield later. Only a few weeks ago, when the Union army launched a massive counterattack, the warships were so powerful that the confidence of the Union soldiers and civilians was bursting. It has only been less than a month, and the federal army has lost a large number of soldiers and equipment in the counterattack operation and the subsequent defense and retreat, so that in the very critical battlefield of Aocheng, there is a huge gap between the fighters and warships that can be put into battle at the first time and the psychological expectations of the defending officers and soldiers - after full national defense mobilization, before the fall of the central states, the military industrial production capacity of the Free Federation still has a significant advantage over the Norman Empire, which plundered the industrial resources of Wessex, but to this day, the Austrian city is precarious, The production facilities of many heavy industrial cities were forced to move to the east, and military production was seriously affected. For the foreseeable future, if the war situation continues to deteriorate, the Commonwealth's vaunted war potential will continue to be weakened until it is tactically and strategically defeated......

The fleet of federal aircraft and the fleet are in unison, and the Norman fleet is not alone. When the Federation fleet arrived over the city, the area controlled by the Norman army suddenly thundered, and various ground guns opened fire on the Federation warship. Despite the lack of heavy anti-aircraft fire at the level of fortress guns, the accumulation of numbers still caused considerable trauma to the Federation fleet. By noon, the Federal Air Force had a slight advantage in the field, but it was unable to completely drive the Norman fleet out of the airspace of the Austrian city. As the warships on both sides continued to determine, some crashed and some left the scene with serious injuries, the number of flying warships gathered in Aocheng gradually decreased from nearly 100 to more than 40, and the sense of oppression caused by these steel behemoths to the ground personnel was correspondingly much lower. Therefore, with no score in the air, the Norman army that had entered the city restarted, and the city was followed by the sound of heavy gunfire and explosions.

In the factory area where Weiss led his troops, the Union soldiers responded to the new wave of Norman offensive with a calm attitude. This time, the Normans not only attacked from the north and west, but also Norman soldiers appeared in the east and south directions, and they either threw large forces into the frontal assault, or sent small elite forces to infiltrate, or advanced by chariots, or opened the way with artillery fire, or pursued the victory of skill, or paid attention to delicate coordination, so that the defenders always felt the pressure from all sides.

Weiss had anticipated this danger of being attacked on all sides, and while he ordered the detachments to gradually shrink to the core defense area, he ordered the detonation of preset explosives everywhere. The previous bombardment by the Normans caused nearly half of the traps to be abandoned, and the effect of blocking the enemy was weaker than expected. Although the pace of the Norman attack was somewhat disturbed, the rope around the necks of the defenders gradually tightened, and if the option of turning into the sewers to continue the battle was not considered, Weiss and his soldiers would either be killed or captured, and it was basically hopeless to hold their positions for a long time or break out.

"Brothers, when we go underground, we do not run away, but we continue to fight the enemy in a guerrilla way. Only in this way can we persevere and persist in fighting the enemy! If the enemy wants to deal with us, he will have to pay tenfold and hundredfold. Now, all of them obeyed my orders and entered the sewers along the maintenance route in the order of the 3rd, 2nd, 4th, and 1st detachments and the principle of priority for the wounded. Everyone should carry as many weapons and ammunition as possible. Execute! ”

Before moving down the sewers, Weiss made a brief mobilization to the soldiers around him. There are not many of them, and they are not elite soldiers, and more than half of them have hung up the lottery, and persevering is not a simple sentence for them, but it requires courage and determination, with extraordinary endurance and willpower, to continue to hold on to this dangerous city.
