But the reason why this small island, which was listed as the first target by Yang Zhen before, has not been the target of the bombing is because it has never been possible to determine the location of the target. Although Yang Zhen listed the long-range bomber as a key bombing target as soon as the Anti-United Nations had it, the location of the target could not be determined, and all plans could only be delayed again and again.

In order to cover up the audio-visual, the Japanese instituted strict secrecy measures. Not only have all the routes passing through this critically located island been modified and adjusted. The location of this island is not found on all Japanese maps, whether civilian or military, and the location of this island is blank on all maps.

Not only foreigners, but also residents of Takehara City, Hiroshima Prefecture, which is only three kilometers away, do not know about the situation on the island. Outsiders don't know the location and production of the poison gas factory on this island. All workers were recruited in the vicinity, and the Japanese Army issued strict gag orders against them.

Not to mention foreigners, even people other than workers are absolutely not allowed to land on the island. Even taking a map of the island is subject to the most severe penalties. Except for the secret map of the Japanese General Staff Headquarters, this island is not marked on any map of Japan, including military maps.

Hiroshima Prefecture Seto Inland Sea coast islands, this approximate geographical location Yang Zhen although known. However, the Seto Inland Sea in Hiroshima Prefecture is dotted with large and small inhabited and uninhabited islands. Which one is this Okunoshima, I'm afraid only the Japanese themselves can know. The Anti-Union also didn't have so many bombers and bombs, so they bombed one by one.

In order to determine the location of this island, Yang Zhen spent a lot of effort. Almost every member of the Japanese poison gas warfare unit who was captured was subjected to the most severe interrogation. From soldiers to officers, and even all university professors involved in poison gassing, were included in the interrogation.

On the basis of the confessions of the interrogation of captured Japanese chemical warfare experts and captured officers of the poison gas unit. Combined with an old Japanese map from 1910 found in the ruined ruins of Xinjing, and a map of the Japanese army's 516 chemical warfare units captured in Qiqihar and Xinjing, and a comparison with the current military maps of the Japanese mainland, the approximate location of this island was determined at the end of 42.

After determining the approximate location of the island, in view of the peculiarities of the island and the air defense forces in the vicinity that almost exceed the urban area of Hiroshima, an important Japanese military industrial base. Li Ming, commander of the bombing command, personally took command and dispatched a group of the best operational staff officers to continuously study the battle plan. The final plan, Yang Zhen has to personally inquire.

Although the location of the island was finally determined, nothing is known about the situation on the island. Despite all the forces of the intelligence system, not a single photograph of the island was found. In the absence of an accurate map and the actual location of the target, it was very difficult to bomb this island, so Yang Zhen had to act cautiously.

Aside from a 1910 map of the Seto Inland Sea in Japan, which was surveyed by the Americans, there is little reference for it. However, it is difficult to determine the location and carry out precise bombing by relying on maps alone. It's hard to make a final decision without coming up with a detailed plan. Therefore, although this Okunoshima Island was definitely in the top two among the bombing targets of the Anti-Japanese Union, it was not until the end of 42 that the bombing plan was finalized.

A carpet bombing was carried out to destroy the Japanese army's poison gas warfare capabilities from the roots. The reason why such a large group of bombers was dispatched to deal with this small island. Yang Zhen's meaning is very simple. Didn't I find the exact location of your factory, then I would destroy you completely.

However, judging from the limited scattered information, Yang Zhen judged that the location of this poison gas factory should be the northwest of the island, because this is the most sheltered place on the entire island. So he focused the bombing on the northwest of the island. However, all the buildings on the island were also within the bombing range. Yang Zhen's attitude is not to miss even the smallest house, as long as it is a building.

In order to be as accurate as possible, the bombing tactics adopted the adventurous method of entering at dawn and using the morning light to bomb with a slightly greater intensity. The group of bombers that took off took advantage of the cover of night and entered the Japanese mainland from the northeast of Hiroshima Prefecture. Take advantage of the opportunity in the early morning when the sky is just bright and the ground target is relatively clear.

At the same time, taking into account the difference in the time of sunrise between China and Japan, in order to ensure this operation, eight Il-4 bombers were specially arranged, carrying a large number of flares specifically for target designation. At the same time, each plane carried six 50-kilogram low-resistance bombs newly developed by the Anti-United Nations as ground fire suppression aircraft.

In order to prevent the bombing from injuring the pilots by the poison gas leakage, all pilots involved in the air raid were required to wear gas masks after entering the Japanese mainland. But no matter what they did, Yang Zhen made only one request to them, even if all the planes were lost, but all the buildings on the island should be completely wiped off the ground.

The reason why the B-24 bomber was chosen was because this kind of aircraft is the largest bomb load and the fastest cruising speed among all the bombers of the Anti-United Nations at the present time. With a range of more than 2,000 kilometers and a bomb load of two and a half tons, it surpassed that of the Stirling and B-17 bombers.

Considering the importance of the bombing, although there were also a lot of drills in advance, detailed tactics were formulated. However, after asking Yang Zhen for approval, Liming decided to personally lead the team to carry out the bombing mission. On 27 December, under the cover of the simultaneous bombing of the Hiroshima Arsenal by the Anti-Japanese Union, and the full radio suppression of electronic warfare planes.

Forty-two B-24 bombers under the command of Dawn began to bomb after the main bomber group arrived over Hiroshima and the surrounding Japanese air defense forces were attracted to it. Immediately command the group of planes on the bombing mission, turn northwest and go straight to Okuno Island.

In the past, the bombing of Japan by the Anti-Japanese Union has always been in the mode of night bombing, and it has never been bombed at dawn. Coupled with the high-intensity suppression of wireless communications on the entire Japanese island of Honshu by the two electronic jamming planes participating in the war, the bombing caught the Japanese by surprise.

Not only the air defense of the entire Hiroshima urban area was relatively slow to respond. The air defense forces around Okuno Island did not take the slightest precaution. Because the Japanese army still has considerable confidence in its ability to keep secrets. Even they never imagined that the secret of this rather inconspicuous island on the seaside of Takehara City, Hiroshima, would one day be revealed.

Moreover, compared to this island, which the Japanese thought was well concealed secrets, there were not only a large number of arsenals in the city of Hiroshima, but also Kure, an important military port and shipbuilding base in Japan, throughout Hiroshima Prefecture. This Kure port, along with Yokosuka, Sasebo, and Tsukishima, has always been the four most important military ports of the Japanese Navy. At the same time, opposite Kure Port, there is Etajima, where the naval academy for training Japanese naval officers is located.

It can be said that the entire Japanese naval defense system in Hiroshima revolves around this Kure port and Kure naval factory, plus Etajima. You must know that Kure Harbor is now building a large number of naval ships, but the navy is the lifeblood of the war. Although the Yamato-4 ship under construction there has been dismantled, there is still a third ship that is being converted into an aircraft carrier.

Etajima is the cradle of the Japanese Navy and the seat of its roots. The Navy does not want its basic military academy, like the Army's non-commissioned officer school and the Army University, to be bombed repeatedly. The hundreds of trainees who were most urgently needed went to the arms of Amaterasu before they could report to the emperor on the battlefield.

It is true that there are armories in Hiroshima Castle, but those arsenals belong to the army and have nothing to do with the navy. The poison gas factory on Okuno Island is also owned by the Army, and even less to do with the Navy. The air defense of the navy is concentrated in Kure Harbor, and the navy in other places will not take care of it.

Even at dawn, when the Japanese Navy was dividing its forces, the Japanese Navy had set up a base radar station around Kure Port, which was also the first roadbed radar station of the Japanese Navy, and it had discovered that some of the bombers from the anti-coalition bomber group that attacked Hiroshima were continuing to fly rapidly in the northeast direction. Although the target has not yet been determined, the radar station with decent naval performance is after all the group that discovered the dawn.

Moreover, after careful calculation, the staff of the Navy's radar station has calculated that the target of this part of the bomber group separated by the Anti-United Nations is likely to be the Geyo Islands, where Okunoshima is located. As for the island of Shikoku further east, the Navy could not think of anything there that could be bombed. As for the Army's two bases in the Eiyo Islands, that is, the Army's ship unit, the goal should be there.

It was only because of the estrangement between the army and the navy that although the navy's radar station had already discovered the abnormality, the army was not informed of the incident at all. The navy was too busy with the security of Kure Harbor and Etajima, where there was time to take care of the affairs of the army. When it comes to the relationship between the army and the navy, the Japanese navy has always been good at keeping things alone.

The army and navy of every country are engaged in contradictions over military spending and resources, and this is a common problem of all countries in the world with comprehensive military services. However, the Japanese army and navy do not even say anything, and they do everything in their own way, and they do not inform each other of anything, I am afraid that they are still the only one.

The Navy builds tanks, and the Army builds submarines and aircraft carriers. The introduction of the same weapons, even if the army and navy take a fancy to it, they don't buy it together, you buy yours, I buy mine. The Navy escort team was attacked by a U.S. submarine on a route, and would never inform the Army afterwards that the route was unsafe. Similarly, when an army fleet is attacked, it is absolutely not informed of the Navy.

In terms of the transfer of materials, the two armies also did their own thing. The two sides would rather empty their precious fleets and Lang cost more precious fuel than allow the shipment of much-needed supplies from the other side. When US submarines set up ambushes on Japanese routes, they often did not need to change places for three or two days. Because the navy moved its nest when it was attacked, the uninformed army still had to take this route. The American submarines that participated in the attack often returned with a full load.

If an aircraft company manufactures aircraft for the army and navy at the same time, but the navy's aircraft must not use army parts. The technology of army aircraft must also not be shared with the Navy. Even the unit of measurement of the instrument is the metric system of the army, and the imperial system of the navy, and the same unit is resolutely not adopted.

When making airplanes, the screws on the Navy aircraft were turned to the left, so the planes of the Army had to be screwed to the right. At the time of manufacturing, it is absolutely impossible to share a common workshop. The high-quality Igarashi cemented carbide aluminum developed by the Navy for aviation is also absolutely not used by the army.

As a major naval power with the world's third-strongest navy, the army has to build its own sea transport ships and submarines, and even the army has to develop its own aircraft carriers. Moreover, the army would rather develop it from scratch slowly, and resolutely do not use the navy's shipbuilding technology, and of course the navy will not give the army technology, which is probably the only one in the world.
