In the Pacific theatre of World War Two, Japan was the clear aggressor. The country had launched a devastating surprise attack on Pearl Harbor on the 7th December, 1941, and quickly conquered much of Southeast Asia.

 

However, by 1945 the Allies were starting to gain the upper hand. In this article, we will explore how the Allies finally defeated Imperial Japan and brought an end to World War Two in the Pacific.

Background

One of the key turning points in the war came in 1942, when the United States won a decisive victory at the Battle of Midway on the 4–7th of June.

 

This was a major naval battle, and it put an end to Japan's dominance of the Pacific.

 

Soon after, the Kokoda campaign was also critical in stopping the Japanese advance in New Guinea.

 

In this campaign, which lasted from the 21st of July to the 16th of November 1942, a small group of Australian soldiers held off a much larger Japanese force, buying time for the Allies to mount a counteroffensive.

Island hopping

By 1944, the United States had built up a large army in the Pacific theatre.

 

This army, under the command of General Douglas MacArthur, began a series of island-hopping campaigns to drive back the Japanese. 

 

Island-hopping was a strategy that consisted of taking back key islands that were under Japanese control, using them as bases to launch attacks on other Japanese-held islands.

  

The most important battle of this strategy was the Battle of Leyte Gulf, which took place on the 23–26 October 1944.

 

It was the largest naval battle of World War Two, and it resulted in a decisive Allied victory.


Battle of the Philippine Sea

On the 19th of June 1944, the United States launched an attack on the Japanese-held Mariana Islands.

 

This was known as the Battle of the Philippine Sea, and it resulted in a crushing defeat for the Japanese.

 

The loss of these islands meant that the Japanese were no longer able to launch air raids on mainland United States.

 

The most famous event of this campaign was the event known as the 'Great Mariana Turkey Shoot'.

 

This was a large naval engagement in which the United States destroyed over 400 Japanese planes.

Capture of the Philippines

In 1944, General Douglas MacArthur returned to the Philippines to fulfill his famous promise to the Filipino people that he would return after his forced departure in 1942.

 

MacArthur, who had been serving as the Supreme Commander of the Allied Forces in the Pacific, led a massive amphibious invasion of the Philippines, with the goal of liberating the country from Japanese occupation.

 

The campaign began on October 20, 1944, when Allied forces landed on the island of Leyte.

 

The invasion was supported by a massive naval and air assault, and MacArthur famously waded ashore onto the beach in Leyte, declaring, "I have returned."

 

Despite fierce Japanese resistance, the Allied forces were eventually able to establish a foothold on the island, and over the following months, they continued to push the Japanese back.

 

In February 1945, Manila was liberated from Japanese control, although the battle for the city was one of the most intense and destructive of the entire war.

Battle of Iwo Jima

In early 1945, the United States invaded the island of Iwo Jima. This was a small but strategic island, as it provided the Allies with a base from which to launch air raids on mainland Japan.

 

The battle was fought between the 19th of February and the 26th of March 1945 and resulted in a costly Allied victory.

 

This battle was particularly difficult because the Japanese had dug tunnels and bunkers into the volcanic rock of the island, making it difficult for the Allies to root them out. In the end, however, the United States was able to achieve victory over the island.


Invasion of Okinawa

The final major battle in the Pacific theatre was the invasion of Okinawa. This took place between 1st April and 22nd June 1945 and resulted in a costly Allied victory.

 

The island of Okinawa was important because it provided a base from which to launch an invasion of mainland Japan. 

 

This battle was fought mainly by United States Marines, who faced stiff resistance from the Japanese defenders.

 

In the end, however, they were able to eventually seize control of the island.

Kamikaze attacks

By 1945, the Japanese were desperate. Their army was retreating on all fronts, and they knew that an Allied invasion of mainland Japan was inevitable.

 

In a last-ditch effort to stop the Allies, the Japanese began using Kamikaze attacks.

 

Kamikaze pilots would fly their planes into Allied ships in suicide missions. This caused significant damage to the Allies, but it was not enough to turn the tide of the war.

 

These pilots made significant impacts in the battles of Leyte Gulf and Okinawa, but in the end, they were not enough to save Japan.

Firebombing of Tokyo

The Allies launched Operation Meetinghouse on the night of 9th to the 10th of March 1945.

 

This operation saw the United States Army Air Forces drop thousands of incendiary bombs on Tokyo.

 

The resulting firestorm killed over 100,000 people and destroyed 16 square miles of the city.

 

This was the single deadliest air raid of World War Two, and it demonstrated the Allies' willingness to use whatever means necessary to win the war.


The Bombing of Hiroshima and Nagasaki

By early 1945, it was clear that the Allies were going to win the war in the Pacific. However, the Japanese refused to surrender, and they continued to fight fiercely.

 

In order to force them to surrender, the United States dropped two atomic bombs on Japan: one on Hiroshima and one on Nagasaki.

 

These cities were chosen as the targets because they were large industrial centres that produced a lot of the resources Japan used in the war. 

 

The first bomb was dropped on the city of Hiroshima on the morning of the sixth of August.

 

In the space of one day, over 70,000 people were killed and another 70,000 were injured.

 

The second bomb was dropped on Nagasaki three days later. This bomb killed an estimated 40,000 people.

 

Also, during this time, the Soviet Union declared war on Japan on the 8th of August 1945.

 

This placed significant pressure on Japan, as they now had to fight a war on two fronts.

The Surrender of Japan

On the 15th of August 1945, Japanese Emperor Hirohito made a radio address to the nation in which he announced Japan's surrender.

 

This finally convinced the Japanese to give up, and on September 2nd, 1945, they signed a formal surrender agreement with the Allies. 

 

In September of that year, Allied forces occupied Japan and began the process of rebuilding the country.

 

With Japan's defeat, World War Two came to an end. The Allies had emerged victorious from one of the deadliest conflicts in human history.

 

Over 60 million people had died during the conflict in Europe and the Pacific theatres.


Summary

In conclusion, the Allies defeated Imperial Japan in World War Two through a combination of island-hopping campaigns, conventional warfare, and nuclear weapons.

 

This victory brought an end to the war in the Pacific theatre and led to the eventual surrender of Japan. 

 

The bombing of Hiroshima and Nagasaki was a controversial decision, as it resulted in the deaths of so many innocent civilians.

 

However, it is important to remember that without these bombings, the war would have continued for much longer, and many more lives would have been lost. In total, over 60 million people died in World War Two: this includes soldiers who were killed in battle as well as civilians who died as a

 

The aftermath of World War Two was felt all over the world. In Asia and the Pacific region, millions had been killed or wounded, and entire cities had been destroyed.
