The secret language of war is sent out almost simultaneously using the short and medium waves emitted by the Funabashi communication and the ultra-long wave of the Isomi communication station; From this point of view, even if Lin Xiuxuan's plan failed, in the early morning of that day, at least five Yi-class submarines acting alone would lay down their special attack submarines and launch an attack on Pearl Harbor. In fact, warships above the mobile force cruiser are also equipped with * special radio stations, using winding antennas, which can receive long-wave information with a wavelength of 17 meters that were originally sent to underwater submarines.

Before Nagumo prepares to deliver his final agitative speech and raise the Z-shaped flag. Five motherships have approached an area 20 kilometers south of Ford Island.

After a month-long period of secretly sailing, the submariners who had secretly sailed, also in frustrated waiting, suddenly received a message to start a war to climb a new high mountain, and they started to work at a random high speed, and these people would become the first batch of special attack members of the Japanese Navy in this war, and they would carry out an attack with no return.

The characteristics of Pearl Harbor are that the water depth is not ideal, and second, it has a narrow entrance, and the above two points have created the unique anti-submarine advantage of this base, and the US Navy has set up an anti-submarine net at the entrance, and any large submarine wants to sneak into the port from such precautions, it is wishful thinking. However, the Japanese are always very good at observing their opponents in the shadows and coming up with some targeted evil moves.

In order to hide people's eyes, the Navy gave the special attack submarine an unlucky name - Marked A, which sounded like some kind of target ship.

On the Yi-22 submarine, a small celebration of victory has just been completed, and the scene is slightly tragic, not so much to congratulate the victory, but to say goodbye to the body.

The captain of the I-22 mothership, Iwasa Shoji Shoji, was also the captain of the agent submarine on board, and this arrangement was conducive to encouraging the junior soldiers to die generously, so the Navy also tended to do the same.

After drinking the send-off wine, Shao Zuo and Jun Cao Sasaki climbed into the SPS22 special attack submarine fixed on the deck in the dark. This is a pocket submarine with an internal diameter of only 1.6 meters, but the weapon is not shrunk, and it is equipped with 2 450 mm spears*, which is very powerful, and any one hit is enough to paralyze a warship of more than 10,000 tons.

Docked around the I-22 side by side are the other four mother boats, as well as the A mark on them. The submarines made contact with each other with great restraint in the use of urging light signals, and they wished each other success, and met at Pearl Harbor and Kudanzaka.

All 5 submarines broke away from their motherships and headed for their targets in the north. This kind of submarine does not have any navigation equipment except for a compass, but since there is no return, there is no need for extra equipment.

2:30 a.m. The deck of the Akagi was still empty, and the deck work before the start of the war had not yet begun. But all the personnel were already neatly arranged around their respective posts, energetically waiting for Nagumo's lecture.

These days, Lieutenant General Nagumo has indeed had too many grievances, and even now, he can't understand the belated arrival of local news, but he has finally unloaded his burden.

“…… The raid is imperative, and the success depends on the elites; At this moment, too much pre-war agitation is meaningless. All you need to do is reraise the historic Z-shaped flag raised by Commander Togo during the Battle of the Sea of Japan in the 38th year of the Meiji era, and you will surely return in triumph. ”

As soon as his words fell, a piercing banzai cry sounded again on the Akagi, shouted as many as 20 times. Immediately, the Japanese Navy, which faced the superstitious spiritual power, slowly raised the mast with a flag of special significance.

At this time, No. 419 had no intention of observing the battlefield, and after receiving the secret message of war, she quickly passed through the side of Pearl Harbor and immediately returned to Tokyo Bay as fast as possible. The main task now is to bring Lin Xiuxuan and his team back safely. Due to the hasty landing plan and the fact that they had brought too much equipment, Lin's group did not bring much food, and Cheng Dayang was worried that if he delayed for a few more days, Director Lin would be in danger of starving to death.

Outside Pearl Harbor, the No. 16 spy submarine was the first to arrive at the predetermined location, the light conditions were still very poor, and it was almost impossible to join up with other submarines.

3.5 kilometers away from SPS16, Second Lieutenant Hiroo's SPS22 special attack submarine was the first to run into trouble. Set sail too hastily, so he and his mechanic Yoshio Katayama Shoso. There was no time to drain the seawater that had accumulated at the bottom into the boat. With the water accumulation, it doesn't seem to hinder the speed of the ship too much.

But while driving, the lead-acid battery pack began to react with the seawater, producing a dizzying poisonous gas, and the interior of this near-disposable submarine was unventilated. Katayama tried to open the top lid to expel the gas, but the cramped interior space and the fact that he was carrying a saber in the way of his feet and feet caused him to not act quickly enough. The concentration of asphyxiating gas in the boat increased rapidly, causing the two men to fall into a coma and suffocate to death. The submarine then lost control and floated to the surface.

A U.S. PBY plane is patrolling from north to south. This was the third aircraft of its kind to take off in the early hours of the morning.

As soon as the plane arrived and left the port, a suspicious target was spotted. The observer from the Texas countryside had remarkable eyesight, and he saw a silhouette moving on the near-dark shore.

He thought it might be a buoy, but he couldn't eat it accurately, so he reminded the captain to go around again. It was later determined that the thing was indeed moving, much like a surfacing submarine sail cover. There was some deep water * on board the Katrina anti-submarine aircraft, however, the captain, Captain William Turner, did not dare to act rashly. A few days ago, he had been instructed that he could fire at all targets with ill intentions, but the criteria for determining targets were somewhat ambiguous, and no one had yet told him that the United States might be at war with other countries. The captain decided to play it safe and dropped a flare on this suspicious thing to indicate the target for the nearby destroyer.

Agent SPS18 underneath was completely unaware that it had been discovered. The captain, Second Lieutenant Shigami Yoshino, was driving through the periscope towards the dim light of the harbor ahead. Originally, after entering the target area, he should enter the state of submarine, but he did not have the means of effective ranging, and some coveted higher speed of surface navigation; In short, for such an outlaw who believes in the favor of fate, the details have been completely ignored.

The cruiser USS Detroit, which was cruising nearby, rushed at a high speed of 25 knots towards the red smoke wafting in the air. The cruiser traveled from west to east, which made the slightly lit sky in the east a good backdrop. During the search, the observer saw a suspicious floating object in front of him, which would have almost been used as a buoy with the tide if it had not been for its speed of up to 20 knots. Like the anti-submarine aircraft, the cruiser received only ambiguous permission to fire, to some extent, the captain was at his own risk in identifying the target. So the captain decided not to use the gun, but to ram the target, at least like an accident.

Second Lieutenant Yoshino, who had taken methamphetamine, was in a state of tirelessness, and he sat in the command position almost naked, but the drug paralyzed his senses, and he almost heard the rumbling sound outside the hull before turning the periscope. A huge black shadow had obscured all of the periscope's field of view.

The 8,000-ton cruiser instantly opened a hole in the pitiful, less than 45-ton iron can, and in 15 seconds, the sea water filled the submarine, causing it to sink.

At the same time, at the preset position 320 kilometers north of Oahu, all six Japanese aircraft carriers were filled with steam, and it was a hot scene. On the skillful aircraft carriers Akagi and Kaga, the flight squadrons that had completed the first wave of attacks were arranged, with the light Zero squadron in front, using the shortest runway; Dive bombers with a load of 250 kg * are in the middle, they are the backbone of the attack; Bulky, and decisive attack power of the Type 97 * bomber, ranked last.

Nagumo stood on the bridge covered in hammocks and looked down at the fighting pilots. According to the plan, the submarine forces should have already mixed into the harbor by this time. But he didn't quite believe that the mere ten* carried by those little things could do anything. His air attack wave will rain down 40 pieces* and close to 80 tons*, which is the firepower that completely buries the Pacific Fleet.

In fact, whether it is by submarine or airplane, both methods have been tested in combat in Europe, where fierce fighting is raging. A year ago, the aviation raid of the British aircraft carrier on the military port of Taranto was an unprecedented success; 3 months ago, 5 Italian men* and tried to carry out a sneak attack on Alexandria, which failed. Nagumo is quite worried that those submarines that have already launched operations may expose their plans in advance, thus adding chaos to themselves.

Light communications between the ships have become more frequent, and judging from the US Navy communications that have been monitored, the number of telecommunications has not increased, which is clear evidence that they are still in a state of paralysis.

5 a.m. SPS22, controlled by Shoji Iwasa, was quietly waiting near the entrance to Pearl Harbor, and he was the highest-ranking officer in this assault, and he was given the command of the entire operation, of course, it was impractical to cooperate in combat. There is no communication equipment on the submarine, and even if there is, it will not be allowed. Now, he has absolutely no idea where his subordinates are, and he doesn't know that 2 mini-submarines have been reimbursed. So far, the U.S. military has not fired a single shot.

According to information from Hawaiian spies, the early hours of the morning are the time when large U.S. military transport ships are likely to appear outside the port, and they usually transport aviation fuel in the morning. No. 22 is like a wolf lurking in the grass, turning the periscope from time to time. There are one or two U.S. destroyers circling around, and they are still far away.

The supply ship Antaris appeared in his field of vision, and Shaozo turned around and looked not far behind him, Sasaki, who was wearing pants and covered in engine oil, nodded with a smile.

"Here's your chance. Don't drop the chain there. ”

"Understood, sir."

The cunning submarine quietly slipped past and followed closely. Leaning on the underwater limit speed of 19 knots, try to get as close as possible to the supply ship. The anti-submarine net, towed by the pilot ship, will not take too long to open, and it is necessary to get into it with a hurry. He noticed that an American destroyer was approaching this side, and the relative position was not ideal, but the sky was already getting brighter, and he could not wait any longer, so he could only take a risk. He did not know that the nearby US ships had already communicated with each other through the radio, and his vigilance had been heightened at this moment.

Sirens blared aboard the USS Ward, and the observation post clearly saw periscopes trying to sneak into the harbor following the supply ship. The destroyer then opened fire and drove over.

No. 22 heard the sound of cannons and tried to dive quickly, but it was too late, and the anti-aircraft fire on the side of the destroyer pierced through the bulkhead of the submarine, and the water ingress caused the submarine to sink rapidly. While Iwasa was still struggling at the bottom of the sea, the destroyer that arrived threw deep water* on his head, completely destroying him.
