"Sir, the Germans have reported that they have successfully ended the campaign in Brazil and completely annihilated the American Patton cluster, and are now temporarily resting and preparing for the next attack. Pen & Fun & Pavilion www.biquge.info"

Tsukahara 243 took the battle report and quickly scanned it, the figures written on it that annihilated 150,000 people and destroyed more than 4,000 planes aroused his strong interest, raised his eyebrows, and asked, "Are the results of the battle reliable?" ”

"Reliable! Our observers have verified that there may have been omissions in the German achievements, but there is no deliberate exaggeration. ”

"How many U.S. troops are there in Brazil right now?"

"There may be 200,000 U.S. troops and more than 2,500 aircraft in the whole of South America, including more than 150,000 troops in Brazil, about 2,000 aircraft, and an unknown number of tanks.

Ryunosuke Kusaka wondered: "Aren't German submarines very powerful?" Why haven't the U.S. military's transportation lines been cut off yet? ”

"On the one hand, the German army moved its submarines to the end of the South Atlantic, mainly cutting off the shipping system in the direction of South Africa; On the other hand, the Americans have now made adjustments, making it much more difficult for German submarines to break the diplomatic relationship. The staff officer of the report explained in detail.

In the past, the U.S. military's material delivery route was directly loaded and transported from various ports on the east coast to South America, and the route was long and there were many places to start, but because the Germans' main attention was on the Anglo-Canadian route in the Atlantic, the U.S. military suffered little losses, and the Joint Chiefs of Staff did not pay much attention to it.

After the end of the European campaign, the U-boats rushed to the Atlantic with all their might, strangling the US transport fleet with all their might, and the losses continued to rise, and the Joint Chiefs of Staff could no longer bear it. At the same time, he suggested that the army should go from the air -- the loss of supplies from the sunken ship is only a loss of money, but the loss of people is a big deal.

But even if the loss of personnel is almost non-existent, the loss of material is a headache - it is not a waste of money, what if the war reaches a critical moment but the supply of materials and equipment is not available?

So the way out to solve the problem lies in anti-submarine, and Turner racked his brains and devised a new set of methods for the transport force on a whim:

The supplies to be transported were transported by train to Miami, the southernmost tip of the Florida peninsula, where a convoy was formed. The flotilla usually departs from Miami at dawn and arrives in Cuba in the early evening with anti-submarine services provided by large aircraft and small frigates (there are not enough cruisers now).

Anti-submarine planes can spot the outline of a submarine within 40 meters of water in the daytime with a good line of sight, and although a frigate can only detect a submarine at a depth of about 20 meters, its monitoring range is larger than that of an airplane, and it is even better than radar when the submarine is not protruding.

Although the German XXI submarines can launch underwater attacks with the help of soundphones, they still have to surface to expand their field of vision when looking for targets. Rising during the day is equivalent to a live target, no matter how strong the silent performance is, it is not the best use, so you can only choose to start at night. At first, the U.S. fleet stayed overnight in Puerto Padre, Cuba, and then waited for daybreak before going on the road, and then the planes continued to escort the ......

Along the way, the U.S. fleet spent the first day in Cuba, the second in Haiti, the third in Puerto Rico, the fourth in Dominica, and the fifth in Trinidad...... Relying on the advantages of the Caribbean's many ports and islands, it operates only during the day and takes refuge in the harbors at night - each port is covered with mine nets. It looks awkward and slow, but it works well and the losses are drastically reduced.

Even if it did, it would have taken about 11 days to get to Recife, nearly doubling the time, but the loss rate had dropped to less than 5%. At the same time, this system of not operating night ships is also suitable for the situation in which the majority of novices in the US military operate ships, and it helps to reduce the error and error rate of night operations.

This tactic also forced Dönitz to withdraw the main force of long-range submarines from the Caribbean Sea and concentrate on deploying them in the South Atlantic, while cutting off the South African route, where there were no islands for American ships to take shelter from every night; While pondering the submarine ambush formation, he was preparing to use it next time to attack the main fleet of the US army. As for the important task of breaking diplomatic relations in the Caribbean, he was ready to let the surface ship force carry it out, but unfortunately the latter was too busy to take care of it.

"This anti-submarine system is a bit interesting, we can also learn it, send a telegram to the military command department, tell the US military about the new tactics, let them try in the South China Sea and India direction." Tsukahara groaned and said, "So it seems that the target of the German army's next move is South Africa, do you know the specific time of the attack?" ”

"It's uncertain for the time being, maybe a month or more, and the Germans are stockpiling supplies to Mozambique and Madagascar, and the merchant fleet is flowing every day." Ryunosuke Kusaka asked, "Are we going to continue with the original plan?" ”

"Execution, too, can be regarded as a favor for the Germans, to help them distract the attention of the American army." Tsukahara smiled, "Publish it in my name!" Let's see if there is a deterrent to the United States! ”

In the early morning of 27 September, the US media, which had not yet recovered from the shock wave of the German Führer's speech, suddenly received a telegram from the Japanese army -- "Letter to the People of the United States of America."

“…… In order to retaliate against the above-mentioned rude acts, the United States Government has repeatedly ignored the Japanese Government's desire for peace, and has repeatedly turned a deaf ear to the Japanese Government's desire for peace. In order to avoid harming the innocent, the Commander decided to inform in advance:

The broad masses of the American people are requested to immediately respond to this public notice and evacuate to the inland areas as much as possible, and those who cannot be evacuated should find the nearest air-raid shelters and artillery shelters for themselves, and prepare enough water and food for this purpose...... The offensive will be launched as early as the early hours of October 1, California time.

In this attack, the range of naval artillery attack is 30 kilometers along the coast, and the target of the attack by carrier-based aircraft is 500 kilometers along the coast.

The Commander deeply regrets the loss of innocent lives and property that may result from the attack, and asks the ordinary people to seek compensation from their own government after the fact, which should bear all the losses caused by their repeated hostility to Japan and their repeated rejection of Japan's sincerity for peaceful purposes in order to satisfy the ulterior motives of black-hearted arms dealers, monopoly oligarchs, opportunistic politicians, and ambitious military officers.

From now on, all seas on the east coast of the Pacific Ocean will be blocked, and the Allied forces will not be allowed to enter and exit, and they will be destroyed as soon as they are discovered! ”

"The Japanese are coming to attack the West Coast? Isn't this a joke? Truman made a rare outburst of anger at an emergency meeting of the Joint Chiefs of Staff and shouted, "This must not be allowed to happen!" ”

In view of the current situation, Dewey was also invited to attend the meeting, and his tone was calmer, but the question was sharp: "The last time Horikichi attacked New York, I happened to be the mayor of New York, and that time caused great damage to the city and cast a shadow on the confidence of countless people in the war. Now tell me, generals, is this likely to happen? If it happens, how can we stop it? ”

Turner stubbornly came out and explained: "The Combined Fleet can theoretically do this, and this telegram we measured using the triangular coordinate method, and deduced that the enemy's approximate position is 2,000 nautical miles southeast of Pearl Harbor, and there are still more than 2,300 nautical miles in a straight line from Los Angeles, and it is expected to arrive within 4-5 days." Although we destroyed a lot of Japanese tankers, they were able to get replenishment, so I don't think oil was a key factor in restricting the Japanese movement, at least not yet. ”

"So how can you stop them?"

"At present, the Pacific Fleet is not in order, and it is simply unable to deal with the main fleet of the Japanese army, so it can only rely on aircraft, especially heavy bombers, to intercept it." Turner smiled wryly, "Once the enemy approaches 1000-1200 kilometers from the west coast, we have a chance to detect and attack them." ”

"Chance?" Dewey's brow furrowed suddenly, "Meaning uncertain?" ”

"Yes, spotting an enemy fleet from a distance requires not only the weather and the direction of the wind, but also some luck. In addition, it was difficult to spot the German fleet at night, except in exceptional circumstances. Turner saw that Truman's face was very unpleasant, and quickly added, "But it is relatively easier to find the enemy fleet within a range of 500-600 kilometers." ”

"This is almost also a circle of attack by enemy aircraft, last time they attacked at night!" Dewey was deeply distressed by this, "Since you know where the Japanese army is now, can't you launch a preemptive strike?" ”

"We lack the means of preemptive strike, and the Pacific Fleet is no match for the Japanese army."

"Can't you send planes or submarines to weaken the enemy fleet first? Or we can first make targeted deployment at the position where the Japanese army is going to attack, and strangle the attack at the initial stage. ”

"I'm sorry, Your Excellency, I really can't do it, the search for sea targets is not an easy job, the radar can only see 100-150 kilometers away, and any search must rely on experienced crews for reconnaissance. Besides, the west coast is huge, and the devil knows which section the Japanese fleet is going to fight. ”

"So what do you say?" Dewey glared at Turner dissatisfied, "No amount of difficulty can be a reason for us to be helpless." ”

"First, send additional aircraft to conduct reconnaissance and keep track as much as possible; Second, strengthen the air defense system in various regions and reduce the offensive capability of the enemy's forces; Third, retreat and evacuate the crowd -- you don't have to evacuate all of them, just focus on a few big cities, such as San Francisco, Los Angeles, San Diego, Sacramento, Portland, Seattle, oh, and at most Las Vegas, which is about 400 kilometers from the coastline, which is basically the limit of the Japanese planes. ”

After Turner finished speaking, Dewey began to go berserk......
