Losing air superiority, under the attack of the Boston and Moss coalition forces, the NATO coalition forces retreated step by step, and after a month of tragic tug-of-war, the St. Martin Empire, which had increased its troops again, barely stabilized the front on the line of Moss City, although the Axis army could no longer advance, it was considered to have kept half of the Moss Kingdom, and many oil fields were recaptured.

After the air was completely suppressed, Marshal Caolan immediately appealed to the Chinese Empire for help, hoping that they would send air support as soon as possible, or replace the St. Martin's Empire with better fighter jets to deal with the increasing number of F86 fighters in the Boston Air Force.

After receiving a telegram from Marshal Kaolan asking for help, Fang Ruijun reacted quickly, and the new batch of Golden Eagle 4B fighters that had just been produced was sent to the San Martin Empire. In order to be in a hurry, they did not load the plane on the ship, but relied on the numerous island airports in the eastern ocean, adopted the method of segmented refueling, and the pilot drove the plane directly to the San Martin Empire, and as for the maintenance and spare parts of the aircraft, hundreds of giant beast 2 transport planes were responsible for the transportation task.

The new Golden Eagle 4B fighter has a larger body and better engines. Not only is it faster, it has a longer range, and the fact that it is an upgraded version of the Golden Eagle 4A fighter is similar to the operation, which makes it easy for pilots to get started. Equally easy to get started with is the ground crew, who are able to maintain new aircraft with only a little training, as more than 70 percent of the parts of the two aircraft are interchangeable.

The Golden Eagle 4B fighter jet, which had just arrived, was quickly transferred to the front line after being overhauled. Seeing that the Imperial Air Force of St. Martin was back on the front line, the panicked fighter pilots of the Boston Air Force immediately took to the air, wanting to continue to compete with each other.

In addition to the larger size of the new aircraft, its aerodynamic layout is no different from that of the Golden Eagle 4A fighter, so at first, the Boston pilots did not care, but when the two sides handed over their hands, they found that the other plane's aircraft has long been different from what it used to be, and its stronger hovering performance and higher speed have become a nightmare for Boston pilots.

The Boston pilots were already inferior to the other party's skills, and now that the plane's performance is once again inferior, their defeat is doomed. In the air battle on the first day, the Boston Air Force was shot down by more than two hundred fighters, almost losing half a month's domestic production, which made the Boston Air Force top brass almost stunned.

The battle between the two sides on the southern front has basically reached a stalemate, and the only one who can attack flexibly and inflict losses on the other side is the air force, and now that the Boston air force is suppressed, they will face a very serious situation.

After asking the country to speed up the finalization of the new F104 fighter, the Boston Air Force increased its support for the Moss Kingdom, and a large number of air forces were transferred to the country, and they resisted the opponent's advanced fighters with numerical superiority. The San Maarten Air Force is also receiving more and more new aircraft, and there are new planes with slightly stronger performance than the F86 fighters, and they are fighting with the Boston Air Force.

The air battle between the two sides continued to unfold over the city of Moss, and the Boston Air Force successfully prevented the St. Martin Air Force from attacking the ground forces at the cost of losing twice as many aircraft per day, and the Boston Air Force was largely pinned down there.

The most feared thing about crossing the sea is the countless land-based fighters and bombers of the opponent, and now the Boston Air Force garrisoning the mainland is a large number of troops in the territory of the Moss Empire, which gives the Chinese Empire an excellent opportunity to attack.

Su Zhizhen and Zhang Haiyang had been waiting for this opportunity for a long time, when the Boston Air Force and Army entered the Moss Kingdom in large numbers to fight, they thought that the time was ripe, and the battle plan that had been prepared was immediately launched, and this time the most critical combat operation in the entire counteroffensive plan was named the Uranus Plan.

On July 12, 927, Project Uranus officially began to be executed, and under the protection of the Eastern Ocean Fleet, a large number of civilian merchant ships, loaded with a large number of soldiers and land equipment, began to approach the west coast of Boston. In order to cooperate with this operation, all the submarine forces of the Chinese Empire in the eastern ocean were scattered to various key areas to monitor the movements of the Axis forces.

Even in the area under the actual control of the St. Martin Empire, two new squadrons of Black Feather high-altitude strategic reconnaissance planes were deployed, allowing them to cooperate with a previously arranged squadron to cooperate with high-altitude reconnaissance satellites to conduct 24-hour uninterrupted monitoring of the coastal areas of the Boston Empire, especially its naval ports.

In the early morning of the 21st, the Southern Attack Group led by Feng Ju first approached the coastline of the Boston Empire, and he was about to launch an attack on the port of San Diego. Under the interference of electronic warfare aircraft, the Boston radar system became blind in an instant, and the communication and command system was completely paralyzed.

The Southern Attack Group led by Feng Ju had eight aircraft carriers, and more than 400 Sailfish 2C attack planes took off one after another from these aircraft carriers, and they were divided into many squads carrying guided bombs to carry out fierce bombardment of 12 military airfields, eight radar stations, and communications and command systems in the vicinity of San Diego Harbor.

After the carrier-based aircraft began to bombard, the eight Zhonghua-class battleships began to bombard the coast with the only remaining front main guns after the refit, and in order to make up for the lack of naval gun firepower, a large number of rocket launchers temporarily placed on many container ships also began to bombard the ground. After the shelling, the Marines on landing ships and assault boats began to launch a beach-grabbing landing operation.

What Feng Ju never expected was that Marshal Pershing accurately judged the direction of his attack and set up heavy troops here in advance. Although the Boston soldiers guarding the beachhead suffered heavy losses after the intensive attack of the Chinese Imperial Navy, they still used strong fortifications to desperately block the attack of the Chinese army, and the battle fell into a stalemate for a while.

Marshal Pershing had been waiting for news of the attack, and when the news of the attack on the port of San Diego reached the War Department, Marshal Pershing's heart relaxed a lot, because in his consideration, the port of San Diego was also the preferred target for attack, and the Boston Army in the south was heavily deployed here.

The port of San Diego is close to the Moss Kingdom, and once China successfully lands here, it can cut off the connection between the Moss Kingdom and the Boston Empire, and those Boston troops who enter the territory of the Moss Kingdom to fight will also be cut off. At that time, the two million Boston Army and the one million Moss Army will be flanked by the Chinese Army and the St. Martin Army, and it is only a matter of time before they are gathered and annihilated by the lack of supplies.

If this happens, it will be a great blow to Boston's will to resist, and they will also be able to break through the weakly defended southern border of Boston, strike north along the East Coast, and threaten the imperial capital of Boston before the rest of the West Coast defenders can return to defense.

After receiving the news that the Chinese army was beginning to attack, Marshal Pershing immediately mobilized nearby reserves to replenish the direction of San Diego, which was already heavily garrisoned, and at the same time he began to move a large number of reserves deployed in the north to the south, so as to strengthen the forces there and eliminate the living forces of the Chinese army as much as possible.

The troops under the command of Feng Ju attacked quite violently, and a large number of ship-based helicopters used anti-armor weapons and cluster bombs to inflict heavy casualties on the Boston army, and the latest air-cushion landing craft of the Chinese Empire also played a huge role, these air-cushion landing craft could rush onto the beach and drive on land, and a large number of self-propelled guns and combat vehicles could be placed inside, which provided strong heavy fire support for the landing force of the Chinese army.

Under heavy fire, the Chinese army quickly took control of the beach area near the port of San Diego, and then the troops attacked inside the port and soon took control of the pier. Although the Marines gained a foothold on land, the Boston Army relied on its superiority in strength to quickly counterattack, leaving the Marines unable to advance an inch, and the two sides engaged in fierce fighting in the dock area, and the casualties and equipment losses of the newly landed Marines were rapidly increasing due to their small numbers.

The landing battle at the port of San Diego was raging, but Salt Lake City, more than 50 kilometers north of the port city, did not have the slightest atmosphere of a major war. The faint sound of cannon was like rolling thunder in the sky, which could not arouse the slightest interest of the people here, because each of them was busy, busy producing weapons, busy receiving food, and busy living hard.

In this lifeless city, which has been weighed down by the haze of war, there is at least one person who is leisurely, and he is Qin Lei, who is wearing a jacket and leaning against a bell tower to smoke.

As the base of the 51st Army Corps in Boston, Salt Lake City has a high density of patrols and is more war-alert than the cities in the rear. On the outskirts of Salt Lake City, there are several large military camps, each of which houses seven armies with more than 200,000 troops, which is also an important force in maintaining the security of Salt Lake City, and most of the patrols are from these regular army units. At the same time, the 51st Army was the closest Boston army to the port of San Diego, and once this reinforcement passed, the landing Chinese Imperial Army would be very passive.

Qin Lei, as a special forces subordinate to the Einsatzgruppen of the Intelligence Bureau, his task is to delay the reinforcement of Boston reinforcements, and there are hundreds of special forces like him who are sent to nearby areas by submarine. Hundreds of people are nothing in a large battle, but as special operations personnel, they can definitely play a role more than a group army.
