One of littlest known Campaigns in the Pacific Theatre was the Aleutian Islands Campaign, which took place on a chain of islands off the coast of Alaska, with very harsh weather. The Japanese bombed the port of Dutch Harbour for 2 days in June of 1942, which caused the highest casualties in the campaign. They then subsequently took over 2 if the islands in the chain. The U.S reacted as fast at it could, with countless bombing runs over the Japanese. The turning point was when a U.S submarine sunk 1 destroyer and severely damaged 2 others off the coast. The Americans attacked with 15,000 men including CANADIAN allies. Japan lost only 29 men, but the allies lost around 200 men, all from traps and friendly fire.

The battle ended that same month, however not without major losses, especially for Japan, who lost 4 aircraft carriers 2 battleships and 21 other ships, and killing 10,500 Japanese men destroying most of Japan’s surface fleet, including the IJN Battleship Musashi, which was a Yamato-class Battleship, and was the biggest battleship of all time.
When the American marines landed on Iwo Jima, they didn’t think anyone was alive due to heavy bombing by American ships. In February, 1945 they landed on the island, but it was too quiet, all of a sudden motors and machine guns began firing on the Americans. The Japanese had 22,000 troops on the island, most of which survived the bombing. The Americans attacked with 70,000 marines. It was a game of cat and mouse due to the many caves around the island. Overall the 5 week campaign killed 7,000 American soldiers, and killing 21,000 Japanese men. This was eventually turned into a movie.

In 1939 the American’s began working on a Nuclear bomb of their own, mainly because Nazi Germany was also trying to build one. In late-July of 1945 the Japanese government rejected the request from the Allies to surrender. Top military generals wanted to use conventional bombing techniques followed with a massive invasion, which would cause U.S deaths of up to 1 million soldiers. To stop the large amounts of casualties, Truman believed that an Atomic bombing would reduce U.S casualties. On August 6, the U.S dropped the first bomb “Little Boy” , killing 80,000 in Hiroshima, and 3 days later on August 9, the U.S dropped the second bomb”Fat Man” , killing another 40,000 in Nagasaki. The attacks killed tens of thousands of more due to radiation. Japan then agreed to surrender, and on September 2, a formal surrender was signed on the U.S.S Missouri.
