When Nan Yun watched with satisfaction that his fleet was about to create another war legend, an air raid alarm suddenly sounded, and then three 250-pound bombs hit the Chicheng, which instantly lost its combat capability and soon stopped at sea. At this time, the hangar in the hull exploded violently, and the burning flame and smoke had spread to the bridge. This is because the engine room lost contact, and Captain Aoki immediately asked Nan Yun to leave the ship. Although Nan Yun finally had no choice but to leave Chicheng, when he was ready to leave, he found that the stairs had been covered by dragons, but he jumped into the sea from the window and was rescued by the cruiser. He temporarily handed over the command to the cruiser Chang Liang. At this time, Yamaguchi learned to replace Nanyun. When Nan Yun boarded Chang Liang, he found that his powerful fleet had been fragmented, and Chicheng Kaga and Black Dragon had been wiped out. Only the dragonfly continued to move forward alone.

Nan Yun's tragedy, personally, many people think that he is an expert in mine warfare and is not suitable to be the commander of mobile forces, which eventually led to the tragedy of Midway Island. In fact, I feel that this is not a tragedy of Nanyun, but an outbreak of the weaknesses accumulated by the Japanese aircraft carrier fleet for a long time. First of all, in this battle, Nan Yun's operational thought was vague. Do you want to capture Midway Island first, or do you want to annihilate the US mobile forces? Because Nan Yun's troops had been fighting in the Indian Ocean during the first half of 1942, they didn't actually participate in the battle plan of Midway Island, which led to the chaos of Nan Yun in the early stage of the battle of Midway Island, especially after the appearance of the US mobile forces, which cast a shadow over the final demise.

Secondly, the second point of Nanyun's defeat is that Nanyun relies too much on subordinates. Nan Yun was an excellent Japanese naval officer when he was young. He was able to bear hardships and learn. However, when Nan Yun was promoted to be a general and commanded the first mobile unit, Nan Yun had the common fault of Japanese naval generals, that is, every general was amiable, but he only signed the subordinate's battle plan and would not think with his own ideas. Pastoral history once recalled that Nan Yun struggled with himself. Over-reliance on staff officers, especially Nayun's chief of staff, Shiro Sukehiro. Mizuho wrote in his memoirs that Nayun gave up the third attack on Pearl Harbor because he followed the advice of the Chief of Staff. Similarly, the first flight team came back at the most critical moment in Midway Island, and Yunyun listened to Yunyun's suggestion, took back the first wave of planes and took off the second wave. It was in these few minutes that the American plane defeated the main force of that cloud and was sent to the sky. The reason why the first wave of flying grass Lulongjieke let Nanyun take back was because many pilots on the first wave were friends of Caolongjieke, and this selfishness made him make a wrong proposal to Nanyun.

Third, Nan Yun is indecisive and lacks decision-making ability. The effect of the first formation air raid on Midway Island was not good. When the first flight commander You Yongzhang asked for a second air raid, Nan Yun immediately asked the plane to hang the bomb and prepare for another air raid. However, when the reconnaissance plane sent a telegram and found the local mobile troops, Nan Yun immediately ordered the hangar to stop loading 1997 aircraft and replace it with torpedoes, preparing to attack the enemy fleet, because 1997 carrier aircraft is a multi-purpose aircraft, which can be loaded with both torpedoes and bombs. So Nanyun can easily replace torpedoes and bombs. Then in half, the reconnaissance pilot sent a telegram saying that the enemy had no aircraft carrier. This is B- 17, which makes Nan Yun decide to change the bomb again. However, the reconnaissance plane sent a telegram saying that there was an aircraft carrier behind the fleet, which made Nanyun messy again and repeatedly operated. Finally, Nanyun's aircraft carrier hangar was filled with all kinds of explosives. At this time, only a small fuse is needed to instantly turn Nanyun's aircraft carrier into a coffin. This is the first time that Nan Yun hesitated in Midway Island, but it is not the last time. When the first wave of aircraft was recovered, Nan Yun's aircraft carrier was loading ammunition and gasoline for fighter planes, and Yamaguchi's aircraft carrier was ready, so Yamaguchi asked his black dragon and dragonfly to take off and attack first, but Nan Yun hesitated before this decision, didn't know how to do it, hesitated for a long time before refusing, and soon the American plane arrived. . . . . .

Finally, another point of Nan Yun's defeat was that he paid too much attention to attack and forgot to investigate. At that time, Nanyun's aircraft carrier was still a single search, and there was no professional reconnaissance plane. This is still an old seaplane used for reconnaissance. Only Chicheng, Nanyun, has brought several zero-change reconnaissance planes, which are still experimental models. This makes it possible for the reconnaissance plane to report whether there is an enemy fleet near Nanyun when the first wave of formation is dispatched in the battle of Nanyun, so that it can use the second wave of formation to attack the enemy, which has appeared twice in the Indian Ocean battlefield. One was an air raid on Yangon, and the other was an air raid on Ceylon. At that time, the other fleet was weak and was quickly annihilated by Nanyun. This is how the British competitive god was killed by Nan Yun. However, on Midway Island, the American Katrina hovered over Nanyun, but Nanyun didn't know the location of the American aircraft carrier for a long time. At the same time, in the Battle of Midway, there was something wrong with the catapults of Reagan and Duima, and Nanyun did not send carrier-based aircraft to remedy it in time, which was also the most important reason for Nanyun's defeat in Midway.

No one is smart or stupid in the war, but both sides keep making mistakes, and finally the one who makes the most mistakes loses the war. Spruance, the "silent prefect", gave us a perfect display in Midway Island. Nan Yun's failure was not his own sorrow, but the sorrow of the senior generals of the Japanese navy at that time.
