At this time, there was a great deal of controversy in the White House over whether or not to land in Japan for armed occupation, and people on both sides held their own opinions, and the final decision fell to the president.

After the Battle of Iwo Jima, the Aleutian Islands, American troops suffered heavy casualties.

And Japan launched the jade crushing strategy in China, and wanted to die together with the landing US troops (mainly relying on the tactics of the whole people, although the kamikaze commandos are notorious, but in fact the losses caused to the US troops are not as great as imagined, at least within the range that the US military can bear).

Japan also armed children and women to prepare for the death of the whole people.

This is a headache for the US military, if it lands directly, it will cause heavy casualties to the US military, and it is not here that is even more fatal, because if it is fought hard, Japan will still be doomed. The important question was the USSR, which at this time was about to attack Berlin.

Germany was the leader of the Axis powers in World War II, and once Germany surrendered first, history would credit the Soviets with the main credit, and the Soviet Union's position and power would also be strengthened, consolidated, and expanded, which the United States absolutely could not allow.

Therefore, the U.S. Congress unanimously agreed that Japan should surrender as soon as possible, so the U.S. government decided to abandon the landing in Japan and instead drop atomic bombs to deter Japan, thus accelerating Japan's defeat.

U.S. President Harry S. Truman and the U.S. government wanted to force Japan to surrender as soon as possible, and also wanted to suppress the Soviet Union, so Truman decided to drop atomic bombs on one of four Japanese cities, including Hiroshima and Nagasaki.

Prior to this, the United States, Great Britain and China issued the Potsdam Proclamation, urging Japan to surrender.

On 28 July, the Japanese government refused to accept the Potsdam Proclamation.

For military and political reasons, the U.S. government used atomic bombs against Japan in accordance with its original plan.

At 8 o'clock in the morning on August 6, 1945, three B-29 US planes entered the sky over Hiroshima from a high altitude. At this time, many Hiroshima citizens did not enter the bomb shelter, but looked up at the American plane.

Previously, the B-29 had flown into Japanese airspace for several days for training, but this time one of the three planes had already been equipped with a five-ton atomic bomb.

At this time, he was ordered to bomb Hiroshima.

At 9:14:17, when the sight and file of the U.S. plane carrying the atomic bomb was aimed in the center of a bridge in Hiroshima, the automatics were turned on.

After 60 seconds, the atomic bomb fell into the air through the open hatch. At this point, the plane made a 155° turn and dived down.

In an instant, the flight altitude dropped by more than 300 meters. This is done to stay as far away as possible from the site of the explosion.

Forty-five seconds later, the atomic bomb exploded 600 meters above the ground, immediately emitting a dazzling burst of intense white light, and a deafening explosion occurred over the center of Hiroshima. In an instant, a huge mushroom-shaped cloud of smoke suddenly rolled up in the city, and then hundreds of pillars of fire were erected, and the city of Hiroshima was immediately reduced to a sea of scorching fire.

The intense light waves of the atomic bomb blinded thousands of people.

The heat of 1 billion degrees has reduced everything to ashes; Radioactive rain will slow some people to death over the next 20 years.

The wind created by the shock wave destroyed all the buildings.

People and things under the influence of the epicenter are falling apart like atoms apart.

A little farther away from the center, the remains of men and women and children could be seen burned down in a flash.

Farther afield, some were lucky enough to be alive, but they were either badly burned or their eyes burned into two holes.

At 16 km away, one can still feel the sultry airflow.

Hiroshima has a population of more than 340,000 people, and most of the people near the center of the explosion died, with more than 88,000 dead and more than 51,000 injured or missing.

Of the city's 76,000 buildings, 48,000 were completely destroyed, and 22,000 were seriously damaged.

However, the tragedy in Hiroshima did not make Japan immediately agree to accept the Potsdam ultimatum, that is, to surrender unconditionally.

They tried their best to cover up the truth of Hiroshima and pinned their hopes on Soviet mediation. On 8 August, however, Japan received an answer from the Soviet leaders that Japan was still engaged in war and refused to accept the Potsdam Proclamation, so that the Japanese Government's proposal for Soviet mediation had lost all ground.

The Soviet government complied with its obligations to the United Nations, accepted the request of the United Nations, and declared a declaration of war against Japan from 9 August.

At 11:30 a.m. on the day the Soviet Union sent troops, the United States dropped a second atomic bomb on Nagasaki, Japan.

More than 60,000 of the city's 270,000 people died that day, causing another tragedy since Hiroshima.

On the morning of August 14, 1945, the supreme head of Japan held an imperial meeting in the air defense room of the Japanese Imperial Palace to discuss the issue of the edict of unconditional surrender.

Emperor Hirohito of Japan, considering the situation at home and abroad and the "national strength and combat strength of both sides," said that if the war continued, "both the country and the future of the country would disappear, and even the mother and child would be lost," and decided to issue an armistice edict.

On the same day, the Emperor of Japan issued the Edict of Armistice, countersigned by the Ministers of Foreign Affairs, saying: "In view of the general situation of the world and the present state of the Empire, I wish to take extraordinary measures to clean up the situation, and I hereby instruct my subjects to order the Imperial Government to inform the United States, Britain, China, and the Soviet Union that they are willing to accept their joint proclamation." ”

At noon on August 15, the Japanese Emperor's "Armistice Edict" was officially broadcast, announcing unconditional surrender. Citizens had no right to hear him.

He did not use the word surrender, but it was understood that the ceasefire was on the terms proposed by the Allies. They know that life has changed irreversibly.

The atomic bombing of Hiroshima and Nagasaki and the Soviet invasion of Manchuria on August 8 finally forced Japan to surrender.

Japan agreed to the terms of the Potsdam Conference. The Allies would occupy Japan and dismantle Japan's militaristic system.

At about 6 o'clock in the evening of 15 August, the news of Japan's unconditional surrender was broadcast by Chongqing Radio, and the citizens of Chongqing set off firecrackers and their joy was unprecedentedly high.

On the short, narrow gray wall of the Chongqing Central News Agency, a huge banner reading "Japan has surrendered" was posted.

Several reporters drove tricycles and banged gongs wildly, circling the city to report the news of Japan's surrender and victory in the War of Resistance against Japanese Aggression to the citizens.

On the evening of the same day, the "National Gazette" published the "Japanese surrender" and went to the center of Chongqing first, and the citizens scrambled to buy it, but the supply exceeded the demand.

The firecracker shop in Chongqing had a good business, and the firecrackers were sold out instantly. At night, firecrackers are set off, and searchlights from all walks of life are set off, shining on the urban area as if it were daytime.

Meanwhile, in the theater where the movie was being shown in Kunming, the audience cheered when the subtitle "Japan's unconditional surrender" was shown on the screen.

They took out their hats and handkerchiefs and danced them in the air.

In the theater where the drama was performing, someone jumped on the stage after hearing the news of the victory, hugged the big flower face that was shaking his tongue and shouted: "Japan has surrendered!" ”
