The U.S. warships have finally left Europe, and although it will take at least 20 days to cross the entire Atlantic, this is enough for the Americans, and as long as these capital ships can return, they should be able to stop the raiding fleet.

The results of the raid on Philadelphia greatly encouraged Cheng Biguang, but he also knew that next, it was impossible to sneak attack such a military shipyard, most of the military shipyards would not be built near the sea, it was too dangerous, most of them were in inland rivers, where there were waterways leading to the sea, except for Philadelphia, other shipyards on the East Coast were not suitable for battleship attacks.

However, on the east coast of the United States, as the original origin of the United States, there are so many ports that can be seen everywhere, more than 3,000 kilometers of coastline, it can't be said that there are ports everywhere, but it can be regarded as loopholes everywhere, Cheng Biguang didn't know that the United States mobilized a large army to come back, the news from Europe, fortunately, a little slower, they attacked Philadelphia, and did not consume much ammunition, after bypassing the encirclement of American ships, they started the third attack, this time, it was not a big city like New York, It's not a military shipyard like Philadelphia, but among the many harbors, a random one was chosen, of course, under the reconnaissance of reconnaissance aircraft, there are slightly more merchant ships in this port, almost more than 50 merchant ships, compared with a big city like New York, it is really incomparable, but among the many ports of more than 300 kilometers around, it is definitely outstanding, such a good target, it is also worth attacking.

The city is called Charleston, located in South Carolina, USA, is the largest port south of Philadelphia developed from the eighteenth century, and is one of the important outlets to the sea in the southern United States.

However, this is the most suitable target among the surrounding 300 kilometers, and it seems that he has few warships, and the defense is also low, after the reconnaissance plane determined the target, and reconnoitred within 150 kilometers around, there is no sign of large fleet activities, there is a harvest, and under the premise of ensuring safety, how could Cheng Biguang not make a move, and the above two are completely different, this time, the time of the attack is very short, only 20 minutes, after 30 minutes of artillery attack with all its might, the fleet left.

However, the attack of the four warships, even if it was only half an hour, was not something that a small port could withstand, and most of the machinery and equipment in the port were destroyed, and all 50 merchant ships were severely damaged, and the warehouse in charge of storage and transportation in the port was basically on fire, and the loss of personnel and property was huge.

This time, less than 4 days before the attack on Philadelphia, after the US Navy received the report, it was a little sad, but in the depths of most of the officers' hearts, they were a little excited.

In this way, the United States can only endure that there is no fleet that can match the emperor class, only relying on those mounted patrols and heavy patrols, at most to play a suppressive role, to limit the emperor class to a certain area, if you want to annihilate it, it is almost impossible, in this case, it can only wait, the United States can only reduce the merchant ships on the east coast at most, and concentrate most of the merchant ships in the direction of Boston, where it is further north, and the bay is shallow, enough to accommodate enough ships to prevent the emperor-class sneak attack.

The actions of the Americans, Cheng Biguang is clear, Boston is also a port, and there are even shipyards, but there are more heavily guarded there than New York, what they need to do is to strike at the weak links of the United States through asymmetrical strikes, so as to affect the mentality of the Americans, and forcibly attack the heavily guarded military port, which is a bit risky. Next, the fleet is like a ghost, wandering in the North Atlantic, or attacking merchant fleets, or attacking small fleets, or sneaking ports, in short, making the entire North Atlantic become full of soldiers, the Americans have thought of countless ways, the Chinese fleet does not love war, always fights and leaves, and gives full play to the speed advantage of battleships to the extreme, fights if it can be beaten, and runs away if it can't be beaten, 4 battleships like the emperor, in this world, there are really no warships that can fight.

Before the return of the main fleet, they had no choice but to be beaten passively, and even the Americans had prepared to hide the news, but under the power of the Allies, the news about the attack on New York was already known to everyone, and now, the affairs of these ports could not be concealed, and more and more news began to boil, and the fleet attacking the east coast of the United States changed from 4 ships to 12, 20, or even 40 ships, and civilians who knew nothing about warships always exaggerated things, even those who have witnessed it are no exception, the fantasy-level strong attack power, every time the attack on the shore, is earth-shattering, and it confirms this rumor.

The final result of quantitative change will be transformed into qualitative change, the entire port part, the city by the sea, everyone is in danger, although it is said that every time a battleship attacks the port, the number of civilians killed is not much, after all, the fantasy class is to attack the war heritage of the United States, although it is said that large-scale anti-personnel will cause greater casualties in the war heritage, but a large number of civilian casualties may inspire the spirit of resistance of the people, which is more than worth the loss.

Such a measure has really played a good effect, the loss of personnel is limited, but the property loss is huge, and the pressure everywhere is on most of the people, who knows what will happen next? Rich, basically, none of them stay in the port city, they have more channels than civilians, the chaebol is of course the first to go, the United States is the world of the chaebol, even if the US government blockade, they can know everything that happens through his inextricable connections, if next, Philadelphia and Charleston are no longer attacked, maybe, they will not act, now, the Chinese are clearly expanding the attack, even ports like Charleston have been attacked, a few days ago, It even attacked a coastal city, which was not a port, but a transshipment base, and several industrial enterprises, which were attacked because of their proximity to the sea.

For Cheng Biguang, this was just a sudden idea, because when the reconnaissance plane was flying along the coastline, it saw a series of industrial areas, although it was not clear from high altitude, but the boilers and large tanks proved that his scale was not low, and attacking him, to a certain extent, was better than attacking the port, and under a series of blows, there were really not many valuable ports.

However, this attack, it is like stabbing a hornet's nest, a city by the sea, no one can stay, if it is not for the factories and enterprises that can't be transported away, they will even move the factory, but most of the valuable machines, precision instruments, laboratories, top scientists, basically do not go to withdraw, after they leave, it is a variety of affiliated enterprises related to them, as well as many seven sisters-in-law and eight aunts and the like, accompanied by more and more people, and then the news can no longer be stopped, and everyone on the entire East Coast is in danger.

The places where the industry of the United States is concentrated, except for the Great Lakes region, are these coastal cities, in the interior, almost to the 21st century, that is, an agriculture-based, the United States' agricultural strength is almost the best in the world, but this kind of strength, for the war has no benefit, in addition to ensuring food self-sufficiency, at most is to exchange more money, the important thing is industry, only industry represents a country's war heritage, can represent the foundation of how long a country can last.

Coastal cities, especially those on the east coast, account for almost 15% of the total industrial output of the United States in terms of industrial value, which is a huge number, because of the attack from the Chinese fleet, this attack is pervasive, as long as there is a target, it will be attacked, the United States has no warships to block, New York, Philadelphia, Charleston, these have been attacked, the US Navy has done nothing at all, there is no way to play a protective role.

Panic is spreading, different from the previous financial turmoil, the financial turmoil, at most let the money go, this is the safety of life and property, now, countless people working in the city, many ports on the entire east coast, involving the evacuation of about 40 million people, it is simply a terrible thing, these people involved in factories and gross domestic production, almost accounting for one-seventh of the United States, no matter how strong the United States is, it cannot bear such huge losses, the direct impact is, Orders, which were supposed to be delivered in the first half of 1916, were almost all postponed.

The financial crisis and the crisis on the east coast are two hammers, which directly hit the weakest link of the United States, and the Americans are also bitter and unspeakable, he has thought countless times, if the fleet can put on its wings and come back quickly, as long as there is a fleet to follow the footsteps of the other side, while pursuing, they can also expel them, and then there will be no problem.

At this moment, what the Americans can do is to let several large fleets start to cruise in North America, but such a fleet only restricts the area attacked by Cheng Biguang at most, and even as soon as their fleet leaves on the front foot, Cheng will attack behind, which simply makes the United States anxious.

However, with the continuation of the attack, especially when most of the personnel located on the beach have run about the same, the effect of the attack has also decreased, no matter what, the attack cannot be intensified all the time, there is a certain limit, the US fleet is still on the way, but every day passes, it is closer to the United States, the Americans do not want Cheng Biguang to leave, they left, who to take revenge?
