In addition to cleaning up the leakers, the Boston Imperial Military also analyzed the current situation, and finally they analyzed that the Thar Navy was originally under great pressure from the Yaman Navy, and now they were expelled from the Mediterranean, with the follow-up Chinese Imperial Navy, plus their own Storm Ocean Fleet, the Allied Navy is facing threats from three sides, and even the world's largest navy is tired of coping.

The Confederates already had a considerable initiative at sea, so they believed that the Saar and Nantes navies could only defend with all their might and could no longer take the initiative.

It's a pity that the Bostonians don't know about the Thar Navy, and they don't know the true meaning of the Navy. Years of experience in dominating the seas have made the Thar Navy deeply understand that the Navy is an offensive service, and if the Navy is reduced to defense, then defeat is doomed, so the Thar Navy is so resolute to send a fleet that is almost a suicide attack mission, attacking the east coast of the Boston Empire, in the hope of pressuring their government to withdraw from the war.

Since they didn't think of a possible sneak attack by the Thor Navy and the Boston Navy didn't think about defending their own coast, they only thought about how to fight back and take revenge.

As soon as the Boston Imperial high-level learned of the defeat of Dewey's fleet, they contacted the St. Martin Empire through cable telegrams, wanting to contact the Yaman Imperial Navy through them, hoping that the two sides could join forces and inflict heavy damage on the Thor Navy.

The wireless telegraph system of the Chinese Empire and its allies is already an open secret known to all countries, but Fang Xiaoyu has always been very strict about it and does not sell it to the outside world at all. Several allies could not obtain it after many negotiations with the Chinese Empire, and this time the Boston Empire could only communicate indirectly with the commercial residence of the Chinese consortium in the Yaman Empire through the St. Martin Empire for fast communication.

After contacting the Yaman Empire, the two sides agreed to meet in the North Sea, and then the two countries would form a joint fleet to attack the anchorage of Scapa Bay, the home port of the main fleet of the Thar Navy.

On the fourth day of the departure of the Boston Navy's Storm Ocean Fleet, Betty's Thar fleet approached the east coast of the Boston Empire, and their first target was Gotham Harbor, the most prosperous port in the Boston Empire.

Gotham Harbor is the largest city and largest commercial port in the Boston Empire, and it is also the economic center of the entire Boston Empire, although the area here is only 1,214.4 square kilometers, it has a population of more than 8 million, and more than 80% of the bank headquarters of the entire Boston Empire are located here.

Fifty kilometers south of Port Gotham is the Brooklyn Heavy Industry Area, the second largest in the Boston Empire, which produces more than three million tons of steel a year, builds more than half of the ships of the entire Boston Empire, and is the most important economic and shipbuilding center of the Boston Empire, and Vice Admiral Betty's goal is here.

Taking advantage of the night, Vice Admiral Betty's fleet had slowly approached Gotham Harbor, and the two destroyers quietly approached the port at a low speed, which was the most economically prosperous area of the Boston Empire, and because it was a free port, the Boston Empire did not place a battery here, and after the departure of the Boston Imperial Navy, it was no longer defenseless.

The approaching destroyer fired a white flare indicating safety, and as the flare rose into the air, Vice Admiral Betty gave the order to attack. Thirty-two 356-mm guns of the four battleships roared at the same time, and in a loud screech, high-explosive shells fell on the business district of the city center.

The huge explosion caused chaos throughout Gotham Harbor, people began to flee in all directions, and a large number of bank headquarters in Manhattan became the focus of Betty's attack, a large number of buildings were blown up, and the vaults were buried deep underground, and the entire city of Manhattan was in ruins.

After dozens of rounds of shelling, the Saar naval fleet began to turn its bow and advance southward, the main target of this attack was the Brooklyn Heavy Industrial District, for which the Saar Empire came up with the latest weapons, imitations of white phosphorus incendiary bombs from the Chinese Empire.

New shelling began, this time due to the presence of a large number of shipyards on the coast, and even cruisers and destroyers approached to carry out shelling in order to destroy the docks of the shipyards along the coast.

The scorching and violent flames of white phosphorus ignited everything, and the entire Brooklyn industrial area was covered in a scorching flame, which caused huge explosions from time to time, revealing that there were also a number of munitions factories here.

The cruisers and destroyers with a relatively close range were specially attacked by the shipyard, and in the intensive attack, the three battleships and twelve cruisers being built here, along with a large number of merchant ships under construction, were burned, and the keel of the steel structure was directly burned and collapsed under the high-temperature flames of white phosphorus, and finally completely scrapped, and all shipbuilding equipment was turned into scrap metal.

After two hours of shelling, the Thar fleet ran out of all the incendiary bombs, and Admiral Betty, who did not know that the Bostonian fleet had already gone east, did not dare to stay long, so in order not to encounter the other side, he immediately ordered the fleet to turn around and go to a predetermined location in the open sea to receive the ammunition supply from the supply ships, and he wanted to continue to advance south, bloodied every Boston Imperial city he passed, and strive to expand the results again, and burn all the ports of the Boston Empire.

The huge loss of Gotham Harbor drove the Boston royal family crazy, and they immediately contacted the St. Martin Empire, hoping that they would allow the Boston Empire's Eastern Ocean Fleet to enter the Storm Ocean through the Guatemala Canal in the territory of the St. Martin Empire, in order to destroy the Saar naval fleet that was wreaking havoc there, because they could not contact the Storm Ocean Fleet that had already sailed without radio.

Regarding the attack on the coastal areas of the Boston Empire, Fang Xiaoyu secretly snickered, and he secretly signaled to the St. Martin Empire to delay time, so that the fleet of the Thor Navy could cause more damage.

For Fang Xiaoyu's intentions, Marshal Kaolan understood it, and he was really ruthless, after careful planning, the intelligence department of the St. Martin Empire caused a collision between two ships in the canal, sinking an 8,000-ton merchant ship and a cargo ship of more than 9,000 tons in the canal, blocking the canal for a month.

The Boston Empire was anxious enough but couldn't attack, people had an accident, and they didn't deliberately let it go, and the fleet was too far to circumnavigate the Strait of Magellan, and it was really too far to quench its thirst.

The Boston Empire and the St. Martin's Empire have also been mortal enemies for more than a hundred years, and although they have now become allies, they are also afraid that the other party will act at a critical moment, so even if the Boston Empire's Eastern Ocean Fleet set sail immediately after receiving the news, it is slow to move because it is too cautious.

With such ample time, Vice Admiral Betty's fleet wreaked havoc on the east coast of the Boston Empire, and the Boston Empire could only rely on coastal batteries to defend carefully, but the Boston Empire had never had any major battles, and the previous confrontation with the St. Martin Empire had always pressed each other to fight, and there was not much consideration for defense at all, and there were not many coastal batteries in various coastal cities.

Vice Admiral Betty also avoided attacking the city without the protection of the battery, and did not announce the return of the fleet until the supply ships ran out of shells. By the time the Boston Imperial Eastern Ocean Fleet circled the Strait of Magellan and headed north again to reach the east coast of the country, Vice Admiral Betty's fleet had already returned home.

After the departure of Betty's fleet, the Boston Empire did not care about the aftermath, and first sent high-ranking officials to negotiate with the Chinese Empire about the purchase of radio equipment.

Upon learning of what had happened to the Boston Empire, the Yaman Empire, the Habfsburg Kingdom, and the Grand Duchy of Sardinia united and expressed their willingness to purchase radio technology.

According to Fang Xiaoyu's original intention, he was reluctant to sell radio technology, but so many allies have expressed their hope to be able to buy it, and if they refuse to sell, it will easily affect the unity between the allies.

If they hold a grudge and unite to do bad things for themselves when they divide the dirt in the future, it will damage the interests of the Chinese Empire, and it is better to be a favor.

What's more, Fang Xiaoyu found that in the people of the Saar Empire, there were already near-successful finished radio products, so Fang Xiaoyu sold radio technology to several allies at a price of 100 tons of gold in the name of recovering scientific research funds.

Now that the radios have been sold, Fang Xiaoyu has not stopped doing anything and registered patents for both electron tubes and transistors. With the development of various countries, the advent of the era of electrical appliances has shown signs, rather than let them steal their own technology in the future, it is better to put it out openly, let them pay patent fees, with the widespread use of several electrical products in their hands, the patent fees of the Chinese consortium can be collected.

The Chinese consortium sold radios to various allies, so that radio technology was no longer unique to the Chinese Empire, so Fang Xiaoyu began to ask scientific research institutions to start new research on radio encryption and decryption technology, as well as electronic jamming equipment.

In addition, he believed that he had used paratroopers several times, but there were no transport planes available, so he could only use bombers for the time being, but fortunately, the new transport planes had been basically finalized, and Fang Xiaoyu asked them to be mass-produced immediately after they passed the military's approval, and the Air Force would also establish a number of special transport aircraft wings.

When Vice Admiral Betty attacked the Boston Empire, a naval battle was in full swing on the sea surface of the North Sea, and the elite of the Yaman Empire cooperated with the Storm Ocean Fleet of the Boston Empire to conduct a big duel against the native fleet of the Thar Empire.

After the Saar Empire sent a fleet to attack the Boston Empire, their fleet also appeared to be undernumered. Avoiding the Sahr patrol fleet, the Yaman fleet secretly left the harbor and joined up with the Boston fleet near Iceland in the northern part of the Stormy Ocean.
