Without much intelligence verification or technical reconnaissance, the Japanese were able to figure out the general situation just by relying on the depth of the shell and receiving radio communications near the port of San Francisco.

The mayor of San Francisco, who was giving a long farewell speech on the radio, mentioned that the proportion of Chinese Americans in San Francisco was actively joining the military far more than in the rest of the United States, and that it was Captain Kennedy, a Medal of Honor recipient who returned from the front, who contributed to this great result. It was he who met with President Roosevelt in May to expedite the repeal of the Chinese Exclusion Act.

The radio then played a recording made by Captain Kennedy. In the recording, Kennedy hoped that the people of all ethnic groups in the United States would unite in the face of a formidable enemy. He further mentioned that when he was fighting in Indonesia, he met a Chinese officer, and his courageous behavior gave him great encouragement. He returned to the United States with the hope of the "Captain Lin" who may have died, and mentioned the amendment to the president to the president, and he was glad that the Senate and House of Representatives unanimously voted to repeal this inhumane "evil law."

On other channels, the San Francisco Police Department announced that as of this month, the search for Japanese Americans had achieved significant results, and that the municipal department had built several new large Japanese concentration camps. The Japanese diaspora will be screened for loyalty, and those who are honest and honest may be allowed to join the U.S. military and go to Europe to fight Nazi Germany. The police department reminds citizens to go to nearby city halls, schools, and police stations to receive the latest published illustrations of the difference between Japanese and Chinese faces, and not to let Japanese spies pretend to be other ethnic groups in East Asia and remain at large.

The war news programs on other channels mentioned that the German new* had attacked London again, causing heavy casualties. And in the Asian direction, the troops of General Chu Tingchang continued to be unstoppable. By press time, Chu Tingchang's army had swept across Southeast Asia, annihilating more than 350,000 regular Japanese troops and 400,000 local puppet troops. At present, the Japanese army in Vietnam is in a panic and is in danger of being cut off from retreat. General Chu's press liaison officer said the Japanese had been lying about having some kind of "superweapon" that could wipe out an entire force.

In fact, this is just a rumor to shake the hearts of the allies, and this kind of thing, called "atomic fission bomb", does not exist. The Japanese army only distorted the explosion of the Indonesian Navy's arsenal into a so-called super*. Most of the Japanese were killed in the explosion of the ammunition depot, but General Mountbatten was unfortunately seriously injured.

After this news, the radio inserted a brief statement signed by Albert Einstein, which said that the so-called atomic fission weapon still exists in theory, just like the dream of human beings to go to the universe, the theory is feasible, but it may take a hundred years of practice to realize, and it is impossible to become a reality in a short time. In addition, Einstein judged that even if this possibility succeeded, it could not have been achieved first by the technologically backward Japanese.

Kanda and his co-captain stood on the enclosure, constantly looking around with binoculars, alerting the U.S. ships. The depth of the enclosure is dangerous, but he doesn't like to dive to periscope depth, which will make him lose his ability to be on air alert, and second, he will slow down, and the precious battery power must be saved for last.

Unlike the newly modified Yi-54, the Yi-12's battery pack is close to the limit, and its performance is much worse than before, and it can only be maintained underwater at a low speed for several hours. Moreover, if the periscope depth is maintained now, then the communication between the two ships will be interrupted.

According to the San Francisco Port Authority's telegraph and wireless telephone calls, the port is currently very busy, and some small boats have left their posts, possibly destroyers or pilot ships, but these are not important targets.

There was some rain in the sky, and the gloomy weather reflected the lead gray of the sea, which made the dilapidated shell easy to dodge, and the eyeliner in the air, but the white track left by high-speed water driving was not easy to hide.

In the distance, there were traces of American ships, about twenty-five kilometers or more, and what appeared to be just wooden fishing boats flying the American flag. Kanda couldn't see clearly with a 50x telescope on the enclosure.

Kanda did not have much confidence in the battery and decided to venture closer to the harbor before diving, and he could only bet that the people on the fishing boat could not see the enclosure that was not much larger than the sampan with the naked eye, but soon the radio intercepted the conversation between the fishing boat and the port authority, and a captain reported to the port authority that he saw two moving floating objects, possibly one or two Nazi submarines. Looks like bumping into a guy with nice eyes.

Kanda and Saeki communicated for the last time (the flag) and said goodbye to each other, and then the two submarines dived one after the other, and at first they could see each other's periscopes from a kilometer apart, but soon, they could not find them, and now they will dive into the harbor on their own.

The original mission of the I-12 was to shoot the explosion through a periscope outside the port, but this mission was temporarily canceled and became a cover for the I-54 to enter the port.

Saeki Shaoza's submarine quickly arrived near the harbor, waiting for a few merchant ships to enter, so that he could follow closely behind the merchant ships and blend in, the Kinmen Strait is 2 kilometers wide, and there is no anti-submarine net, but there are many ships of the Navy and the Coast Guard, and when they enter during the day, they are still easy to be seen by hundreds of pairs of vigilant eyes, and they have to find some cover.

Now Saeki does not know the location of Kanda, only that at the most dangerous moment, it may launch an attack and divert the enemy. Of course, it may not appear.

Two 10,000-ton Liberty ships were entering the port, which did not seem to be a good chance, but waiting too much was not necessarily beneficial, and the Yi 54 decided to take some risks.

He made it to the last American cargo ship at a speed of 6 knots. If the submarine gets close enough, it can hide the white track stirred up by the periscope into the track of the free wheel, and of course, the huge movement from the ship's diesel engine stroke will also cover up the movement of nearby warships.

The captain repeatedly issued orders to correct the course, and after 20 minutes, he managed to hide in an area of 40 meters behind the ship.

This is the closest he can get to manoeuvre, and if he gets closer, he can easily bump into it. Now Saeki can look through the periscope and see the name of the huge "Robert Pilley" with the American flag and paint brush on the stern.

The 10,000-ton ship, launched at the end of last year, was the focus of attention of the Allied propaganda department at the time, because it was a microcosm of the overwhelming superiority of American industry, and it took only four days from slipway to completion.

Of course, today the tired ship is returning home, and the attention of the crew is in the direction of the port, and it is not expected that there will be a Japanese devil submarine, following closely behind its ass.

At the same time, in the rear of the I-54, in the dismantled rear * cabin, the final commissioning of the nuclear bomb is still in full swing. The work of connecting the relays and charging the servos cannot be done too early and must be done before the explosion. As for the depth of the explosion and timing, in fact, the moment when the submarine left Rabaul had not yet been decided, and it was not until the submarine arrived in Marshall that there were several sets of plans, which required the captain to temporarily master on his own.

According to the information obtained by I-12, the surface explosion was even more significant, because according to I-12, fuel storage tanks near the port were found. I don't know why, in the target ranking of the base camp, fuel is always at the top. Japan's national strategy is always full of self-serving and wishful thinking, and many analysts believe that destroying fuel facilities can delay the US military's operations by several months.

By the time the Pilley turned, Saeki could already see the Golden Gate Bridge at the far end of the channel. I don't know where Yi 12 is at this time?

Saeki's hands holding the periscope grip began to sweat, he knew that this was a glorious one, and later he and the brothers here would melt with a dazzling white light, and then appear together at the Yasukuni Shrine. But when it came to the end, there was still some inexplicable nervousness. Nervousness dulled him.

After a moment of stunned effort, I could already hear the roar of the machine outside, which was different from the free wheel, through the bulkhead.

He turned his periscope, and an American submarine was already in sight. The I-54 was too close to the ship, resulting in a huge Liberty hull that obscured the view about 30° ahead, and the ship's noise also masked the destroyer's approach.

The two sides are less than 600 meters apart and appear in their respective fields of vision at the same time. If Saeki's reaction was fast enough, his periscope would have had time to disappear from the US Navy's field of view. But he foolishly confronted the approaching destroyer for a moment before giving the order for an urgent dive. And a non-commissioned officer in charge of observation in the cockpit of the US military just turned his head and saw the periscope of the Japanese submarine.

The 127-mm guns on the USS Grant began to aim, but after completing the loading, the distance was already 300 meters, and the gun depression angle was no longer enough to shoot deep enough below the periscope. According to common sense, under the periscope is the sail enclosure, which is also the area where the command module is located, and it is far more valuable to hit there than to hit somewhere else.

Amid the piercing sirens of the whole ship, the first shell grazed the periscope, and the loud explosion reminded the Japanese that the end had come.

The captain of the USS Grant, Captain Albert Ridge, realized that the enemy's submarine was rapidly descending with the loss of the main gun range.

He decided not to do anything, two cars at high speed, rushing to the periscope, maybe he could use the destroyer's 5.5-meter draft to turn everything in the enemy's periscope and the enclosure of the periscope into two, as long as a few inches of the rift, it was enough for the submarine to sink. Of course, it may be too late for the deep water* to be in time, since the discovery of the enemy submarine, but for a minute, he knows that his rear deck deep water* team has not reacted so quickly.

The destroyer drove at full speed, and the bottom of the blade almost hit the hull, but the Japanese submarine still dodged it. Saeki was below, shouting and ordering the left rudder to evade, he didn't know which direction the enemy's deep water* would come from, but at this time, it was better to turn around than not move.

The Americans, on board the Libership, rushed to the stern of the ship, watched in amazement as the destroyer maneuvered in a serpentine figure behind their track, and then threw deep water from the aft deck rails*. The first few pieces* did not have time to reduce the preset depth of the project, and they fell to the bottom of the water before they exploded. Yi 54 narrowly escaped the first deep-water* attack.

The depth of the strait is not enough for it to dodge attacks by diving deep, and if it is not careful, the submarine will sit on the bottom of the sea. After all, he had information on the depth of water in the main channel of the Kinmen Strait, which was information collected by the US side before the war.
