The best altitude and distance for aircraft bombing, 500 to 3000 meters is the best, of course, it also varies from case to case, but at this altitude, the bombardier is the most comfortable.

If the altitude is too high, it is much more difficult to calculate, and the accuracy is much worse, so many pilots still prefer to lower the altitude to drop bombs.

The fourth formation of the Huafu Air Force flew to the designated area, which was a factory area, and the planes began to reduce their altitude and flight speed, preparing to drop bombs, and suddenly, a group of soldiers in Japanese military uniforms appeared on the ground, where and what to operate.

The plane's ground observer Tong Guò monitor noticed the situation and shouted loudly, "Japanese movements have been detected, they are operating artillery, suspected anti-aircraft guns, repeating, Japanese troops are being operated anti-aircraft guns." ”

After the captain of the fourth squad heard the shouts of the observers, a cold sweat immediately broke out on his forehead, at this altitude, in the face of the enemy's artillery, the group was in danger, he immediately ordered: "The bombers accelerate and pull up, leave this position first, the fighter group, attack the ground, stop the Japanese from firing, and move quickly." ”

At this moment, the Japanese troops on the ground opened fire, and the 4 anti-aircraft guns fired several salvos directly, and huge shells flew into the sky and exploded in the air.

At this time, the fourth formation was only more than 2,000 meters high from the ground, and the German anti-aircraft gun introduced by Japan had a firing height of 5,400 meters, and it was absolutely no problem to hit the planes.

In fact, this can also be understood, later generations counted the number of anti-aircraft guns and planes during World War II, with an average of more than 10,000 shells to hit an airplane. There is no reference point in the big sky, so it is very difficult to hit a plane that is in motion.

The escort fighters of the fourth squadron of the Air Force swooped down, took advantage of high speed and low altitude, and came close to the ground in the air, and fired a round of strafing at the artillery positions on the ground. Several planes all attacked in turn, not giving the artillery positions a chance to breathe.

The machine-gun bullets clanged against the anti-aircraft guns, and several Japanese soldiers who were unlucky were swept away by the airsoft bullets of the plane, and a large hole immediately appeared in their bodies, and blood was sprayed all over the ground, and there was absolutely no chance of rescue.

Ryusuke Koizumi shouted loudly, "Don't stop, fire shells at me." Just take a plane, we will win, you will all be heroes of Japan, do not stop. ”

The anti-aircraft guns continued to fire shells into the sky, chasing the bombers and bombing indiscriminately, but the fighters of the air force were desperately strafing the four anti-aircraft guns with machine guns, and from time to time Japanese soldiers were knocked down. The scene is so weird and cruel.

The fight between life and death is like this, from time to time you die and I die. There is no compromise and no consequences, only non-stop struggle to fight for a future of your own.

A huge bullet was fired into the chest of Ryusuke Koizumi, the young commander of the Japanese Resident Infantry Regiment with a very brain, and died like this. No one in the world knows that more than 20 years later, a general and chief of staff of the Japanese Army was killed by the Huafu Air Force in the small town of Osaka.

"Team 4, how are you doing? Whether there is a loss of personnel. On the radio, the captain shouted quickly.

The captain of the fourth squad hurriedly replied, "Captain, we have left the range of the enemy's artillery, and the fighter squad has cleaned up the ground artillery, and now the ground artillery has lost its combat effectiveness. ”

"Are there any losses in the fighters?" The captain continued.

"There is no big loss, but some drivers heard the sound of shrapnel hitting the body, there should be damage, the specific damage is dù, it is difficult to count now."

"Then can you still fight, if not, you can fly back to the Busan base?" The captain said with concern.

"We can, captain, please let us complete the mission." The squadron leader was unwilling to give up his mission, and was ambushed by the enemy and almost died, he was already very aggrieved, and if he withdrew from the battle, it would make it even more difficult for these soldiers to accept the mission as their vocation.

There was silence on the radio for a while, and then the captain said, "I agree that you will continue to carry out the mission, in order to avoid possible anti-aircraft artillery attacks, carry out high-altitude bombing, you should act faster, and after dropping the bomb, hurry back to me, check the damage to the plane, do you know?" ”

"Captain, don't worry, we won't delay, we will go back directly after dropping the bomb." After the fairy tale of the squadron leader and captain of the fourth squad ended, he turned off this channel, switched to the radio of the fourth squad, and said directly: "Brothers, little Japan dares to yin us, damn them, the captain said, carry out high-altitude bombing, let's hurry up and carry out the mission, and go back to overhaul our plane after the incident, damn, if the plane is lost, I and the little devils are not finished." ”

"Blow them up, and after the plane is repaired, they will have something to see."

"Drop the high-altitude bombardment, don't let these ghost things feel good."

These planes, in the hearts of every pilot, are treasures, are very precious, closer than their own wives, and now they have been injured, even if there is an extra scratch, they will be distressed.

On this day, the urban area of Osaka suffered a large-scale bombing by the Huafu Air Force, and none of the four blocks in the urban area were spared, all of them were bombed more or less, and the losses were incalculable, and this time the Huafu Air Force still consciously focused on the enterprise area of Osaka, so after the bombing, most of the factories in Osaka basically entered a state of stagnation.

Osaka City also carried out self-rescue and disaster relief, although there had been arrangements before, but because of the large scale of the bombing of the Huafu Army, the losses in Osaka were still very heavy, with more than 20,000 dead and wounded, more than 10,000 houses burned, and even greater factory losses.

Fortunately, Japan has not yet developed to the later stage of the hobby of caesarean section, and it is mainly the habit of military personnel who love caesarean section, otherwise these government officials should go to caesarean section.

After the end of the Osaka bombing mission, the Air Force fighters returned to Busan, and after inspection, the planes of the fourth squadron, three bombers suffered damage of different degrees, the most severe plane, which had a large hole about 30 centimeters long in its abdomen, which needed to be repaired for a period of time before it could be lifted off again, and the other planes also had many scratches on the fuselage.

After the incident, the Air Force reviewed the matter and once again emphasized the safety requirements for carrying out the mission.

Of course, in the war, it is impossible to avoid losses on their side, this time the incident is already very lucky, discipline needs to be emphasized, but it cannot be lost because of this, so the Huafu army took a larger bombing operation.

On May 27, the Huafu Army bombed Nagasaki, and the shipbuilding industry, which had been destroyed by Guo Yu once, was once again taken care of, and the city of Nagasaki Prefecture was also full of ravines like land ploughed by ploughed oxen.

On May 28, Nagoya was bombed, and as one of the four major industrial cities, factories and enterprises were taken care of, and the losses were less than that of the Osaka Industrial Zone.

On May 29, Kobe was bombed, and the still industrial area was named.

On May 30, Yokohama was taken care of by the Huafu Air Force, and its important steel, oil refining, chemical, and shipbuilding industries suffered heavy losses.

On May 31st, take a day off, hehe, a combination of work and rest, Wu Dazhu is not a commander without humanity, so he gave the troops a day off, but the Huafu army rested, but they did not notify the Japanese side, all the cities in Japan are still in strict formation, do not dare to relax in the slightest, the next day after all the cities reported the information, the Japanese government only knew, by the way, the Huafu army actually rested, it really made people vomit blood.

One of the things that the Japanese government regrets the most is that it did not attach importance to antiaircraft guns at the beginning, and only purchased 10 antiaircraft guns from Germany for research and imitation, but until now Japan has not carried out research projects on antiaircraft guns, and there is no achievement in this regard.

Now the department that studies anti-aircraft artillery is a little late, and even if it is researched, it will not be rushed, but Japan still hastily launched this project, but it is difficult to say whether it can produce its own anti-aircraft guns before the end of the war.

However, even if Japan really produces anti-aircraft guns, what can it do, can Japan have anti-aircraft guns to stop the Huafu Army's bombing of Japan?

However, Huafujun's planes themselves have advanced bomb delivery calculation equipment, and they are higher than those for dropping bombs, and although they cannot do precision guidance, they are still sure of hitting large buildings such as factories and buildings, so there are really not many opportunities for Japan to counterattack.

In August 1925, representatives of 54 countries around the world held the "International Conference on Children's Happiness" in Geneva, Switzerland, and issued a declaration of love for children and protection of children's welfare. The International Association for the Promotion of Children's Happiness proposed the establishment of Children's Day, and the United Kingdom, the United States, Japan and other countries responded positively and successively established their own children's days.

In November 1949, the Executive Committee of the International Democratic Women's Federation held a meeting in Moscow and decided to make June 1 of each year the International Children's Day.

However, at this time, Guo Yu clearly stipulated that June 1 was Children's Day in the legal holidays of South China.

Children's Day is a happy day, so Guo Yu called Wu Dazhu the day before, asking him to give the Japanese government a gift to carry out a second bombing of Tokyo, and also to give advance notice to ask if the Japanese government is willing to surrender, if not, to bomb Tokyo on June 1.

After receiving Guo Yu's order, Wu Dazhu held a meeting overnight to draft a telegram at 7 a.m. on 1 June, demanding that the Japanese Government reply within five hours.

At the Busan airport, all the planes and pilots were preparing for the war, and this time, if Japan did not surrender or did not reply, the Hwafu Army would have its planes on hand to carry out the largest bombing campaign against Japan. (To be continued......)
