Various anti-aircraft guns and a large number of anti-aircraft machine guns were intertwined into a dense network of fire, turning the sky over the Nantes Volunteer Army into a place of death, but any defense was flawed. After roughly mastering the anti-aircraft guns of the Nantes Volunteer Army, the DO17 bombers of the Yaman Army took the high-altitude bomb drop.

The anti-aircraft guns of the Nantes Volunteer Army were small in caliber and could not shoot at targets above four thousand meters, so the experienced Condor pilots only needed to exceed this altitude to be safe, anyway, the troops of the Nantes Volunteer Army were very large, and even if they carried out carpet bombing, the results would not be small.

The DO17 did not have a large bomb load, and it only took a few moments to drop all the bombs. Without bombs, the bombers immediately began to return home, and at this point a larger number of Junkers 87A dive bombers came into play. Unlike the high-altitude bombardment of the DO17, the Junkers 87A bomber took a precise dive bombardment.

In order to increase the horror effect, the Yaman people have added a sounder to the plane, which will emit a terrible scream when it dives at high speed, creating a terrifying atmosphere.

In the midst of these whistling sounds, one after another Junkers 87A dive bombers, at a dive angle of nearly 90 degrees, dropped bombs on the artillery units of the Nantes Volunteer Army. One bomb after another accurately fell into the artillery queue of the Nantes Volunteer Army, blowing up a large-caliber artillery piece to the ground, and the nearby artillery suddenly panicked.

Junkers 87A bombers dived alternately, accurately dropping bombs into the ranks of the Nantes Volunteer Army, blowing up a large area of blood mist. Although some of the dive bombers were shot down by anti-aircraft fire, they bombed the Nantes Volunteer Army even harder, and almost half of its artillery units were crushed.

Seeing that their own troops were bombed, the Nantes fighter unit, which was entangled with the Condor Legion, wanted to break away from the enemy and expel the other party's bombers. The Nantes fighters attempted to disengage, but the seasoned Condor Legion fighter unit immediately entangled, preventing them from leaving.

Some Nantes pilots with better skills finally rushed out in the more powerful Mustang fighters, and they rushed towards the bombers of the Condor Legion at full speed.

As soon as a Junkers 87A bomber pulled up its nose, it was met head-on by the Mustang fighter of the Nantes Volunteer Army, and the fighter was full of firepower, and the six machine guns were intertwined into a dense fire net, which hit the bomber to the point of bullet holes, and the left wing was also directly broken. The badly wounded bomber could no longer maintain its flight and plunged headlong into the ground, where a blaze erupted.

Under the attack of the Mustang fighters, the dive bombers of the Condor Legion were shot down one after another, and those surviving bombers could only scatter and flee, using their weak self-defense firepower to shoot desperately.

The infantrymen, who had been badly bombed just now, immediately burst into cheers when they saw their fighters coming to support. The elite pilots of the Nantes Air Force rushed out to drive away the bombers, and the remaining Nantes pilots were considered to have fallen into bad luck.

The combat effectiveness of the Nantes Air Force was weak, and after the elite pilots separated, it was even more difficult for them to fight against the Condor Army led by Hartmann, especially those Sony 406 fighters with slightly inferior performance, who were shot down one after another under the blow of the BF109E fighters.

After suffering heavy losses, the Nantes Volunteer Air Force had to retreat, and the Condor Regiment also chose to retreat because the bombers had dropped all their bombs. This battle caused the Nantes Volunteer Air Force to lose more than half, and the Condor Legion lost more than 70 aircraft, but most of their losses were Junkers 87A bombers.

After the air battle, the Nantes Volunteer Army, which had been resting for a while, formed a formation and prepared to attack the city of Coimbra. More than 200 155-mm guns immediately began shelling the defenders of Reese, and the Reese artillery in the city quickly counterattacked. Despite the fact that the caliber of the artillery of the Reese artillery rarely exceeded one hundred and five millimeters, it could rely on the concrete fortress and stubbornly resist the shelling of the Nantes volunteers, and a large-scale artillery battle began on both sides.

The Nantes Volunteer Army opened fire with light and heavy weapons, and the soldiers braved the artillery fire and charged after the chariots. The Renault 35 tank produced by the Nantes Empire was thick-skinned and not afraid of the 37-mm anti-tank guns that the Reese government army was equipped with in small quantities.

Seeing that their anti-tank artillery was ineffective, the Reese soldiers panicked, and they had to call for heavy artillery bombardment, but those large-caliber howitzers were not accurate and did limited damage to the tanks, and only a few tanks were destroyed.

A Reese gunner relentlessly operated his 37mm anti-tank gun, still firing seemingly useless shells, but the effort paid off, and he soon saw the results.

Just as a Renault 35 was turning, the gunner's shell miraculously hit the heavy ventilation grille on the side of the vehicle. The Renault 35 has very good armor protection in the eyes of the countries of the Western Continent, its frontal armor is 70 millimeters, even the tracks and load-bearing wheels have armor protection, but its only weakness is in this ventilation grid.

Due to the high horsepower of the engine, its heat generation is very high, and in order to prevent the engine from stopping due to overheating, the designers had to set up ventilation ducts on the side, and the outside grille is to protect this ventilation duct.

Despite the protection of the grid, such a shuttered grid defense against large-caliber machine gun bullets is good to say, and there is nothing that can be done in the case of anti-tank guns that use special armor-piercing shells, so when this shell hits the grid, almost nothing blocking the grid is penetrated.

Passing through the grid, the hard armor-piercing warhead broke directly into the engine, breaking the oil circuit and cylinder, and the red-hot warhead ignited the nearby gasoline. The Renault 35 chariot shook violently, flames erupted from the bottom of the vehicle, and soon it did not move, and the Nantes army drivers opened the top door in a panic to escape, only to be killed one by one by the prepared Reese infantry.

Seeing the effectiveness of their anti-tank artillery, the morale of the Reese government army was greatly boosted, and they quickly aimed the anti-tank guns in their hands at the grid to attack, and the anti-tank guns were successful one after another, and soon more than 20 Renault 35s were destroyed, causing a commotion among the Nantes army.

Seeing the strong firepower of the opposing side, the Nantes volunteers immediately turned and retreated, but those inexperienced Nantes drivers once again paid the price for their recklessness. It is true that the 37-mm anti-tank guns could not penetrate the Renault's 70-millimeter-thick front armor, and even the 45-millimeter-thick side armor could not penetrate it, but that did not mean that they could not penetrate the rear armor, which was only 25 millimeters thick.

When the Renault 35 convoy retreated, it exposed its weak rear armor in front of the guns of the Reese government army. After a roar of artillery, the Nantes army left behind the wreckage of more than thirty tanks before escaping. The Nantes army has been suppressed for twenty years, they have not updated their equipment over the years, and they lack the necessary training, and now it is indeed very difficult for them to quickly adapt to the new equipment, so he can only try to rely on the mature tactics of the world war to avoid unnecessary casualties.

After the retreat of the attacking troops, the artillery of the Nantes Volunteer Army began to bombard again, knocking down the Reese soldiers who were still celebrating the victory, and even the anti-tank guns that did not have time to retreat suffered heavy losses, although the Reese artillery then began to counterattack, but because the number was too small to suppress the enemy's shelling. After the shelling lasted for half an hour, it began to extend into the city, and the Renault 35 convoy covered the Nantes infantry and rushed up again.

The defenders of Reese, who had suffered heavy casualties due to the enemy's shelling, had to abandon the outskirts of the city and move into the city for street fighting, and the Nantes volunteers also rushed in without stopping. After the last war, all countries studied the new weapons displayed by the Chinese Empire, and found that these weapons were quite practical in specific battlefields, so countries with production and research capabilities imitated these weapons, and all of them were used in this war, which can be regarded as a practical test of the development of weapons in the past two decades.

The Lisbon government army and the Nantes Volunteer Army, armed with their own submachine guns, pistols, mortars and grenades, fought desperately in the narrow streets, piling up their lives on the way forward. The army of Reese had the advantage of geography but was small in number, and the Nantes army, although of high quality, had a headache with the complex streets of Coimbra.

The city of Coimbra was the main communication route between the Grand Duchy of Lysbly and the Kingdom of Sero, and once it was captured, it would completely cut off the connection between the two, so that their troops could not respond and fell into a situation of fighting on their own, so the Nantes Volunteer Army invested a lot of troops in an attempt to capture it in one fell swoop.

The Grand Duchy of Reess also knew what was at stake, and they also relied on the fast railway lines to send weapons and new soldiers here, and the city of Coimbra became a cruel grinding plate of flesh and blood, consuming soldiers and supplies on both sides.

While the battle for Coimbra was in full swing, the Sardinian mercenaries also launched an attack on Lelida. Only one division of the rebel 40th Army was stationed here, and in the face of more than 200,000 Sardinian troops, they had to choose the same street fighting.

The Northern Military Region was originally located in the mountains, and it was facing military pressure from the Nantes Empire on land, and it had always been the military center of gravity of the Cerro Kingdom, but due to the barren land and difficult roads, it has always been a poor area, and the troops that usually raised five armies also needed general funds for domestic support, and now in order to attack the royal family, Franco has doubled the number of troops, which is even more difficult.

Even though the rebels used a near-sneak attack to capture the port of La Crosse, the largest port in the north of the Cerro Kingdom, to alleviate the shortage of funds, the Axis did not have a military presence in the Mediterranean, and after the Allies blockaded it, the financial resources here were cut off, so the rebels have always relied on supplies and loans from the Axis powers.
