1On May 5, 942, the Japanese base camp ordered the capture of midway and the western islands of the Aleutian Islands. In order to carry out this campaign, the Japanese high command used the basic naval forces: 1 1 battleships, 4 heavy aircraft carriers, 4 seaplane carriers, 13 heavy cruisers, 66 destroyers, 22 submarines, and a large number of minesweepers, transport ships and oil tankers.

The above-mentioned troops were organized into six combat formations under the unified command of Admiral Isoroku Yamamoto. Nanyun Zhong Yi vice admiral's carrier assault formation (4 heavy carriers, 2 battleships, 3 cruisers and 12 destroyers) and Fujitsu vice admiral's landing formation (15 transport ship with 5000 landing soldiers, 1 light carrier, 2 seaplane carriers and 2 battleships).

The northern formation (2 light aircraft carriers, 6 cruisers, 12 destroyers, 6 submarines, 4 transport ships and 2,450 landings on other ships) under the command of Lieutenant General Wu Zilang of Xixuan was responsible for capturing Artu and Kiska Island. From 26th to 29th, various formations set sail from the mainland one after another, and are scheduled to launch an attack on Midway Island on June 4th.

In order to avoid the sudden appearance of the American fleet, Japanese submarines cruised in the waters near midway and Aleutian Islands in advance. The Japanese high command thinks that surprise attack is of great significance, so it attaches great importance to campaign camouflage, but overestimates the concealment of its radio communication.

In mid-May, 1942, the US military grasped the Japanese password, found out the Japanese attempt and took necessary countermeasures. Admiral Nimitz, Commander-in-Chief of the US Pacific Theater, mobilized three aircraft carriers (more than 230 carrier-based aircraft) and about 40 other combat vessels to form a 16 special mixed fleet (under the command of Major General spruance) and a 17 special mixed fleet (under the command of Major General Fletcher), which were deployed in the northeast waters of Midway Island and were hidden for standby.

At the same time, the submarine 19 was deployed in the waters near Midway Island to monitor the actions of Japanese ships, and a long-range aerial reconnaissance with a radius of 700 nautical miles was deployed. The island itself has also strengthened its defense. The coast and nearby waters have been mined, and anti-aircraft guns and field guns have also been strengthened. The Japanese army tried to start the action in the direction of Aleutian Islands one day and one night in advance, in order to confuse and attract the American troops in the main assault direction.

1On June 3rd, 942, a northern formation (2 aircraft carriers, 82 carrier-based aircraft and 29 other warships) led by Japanese vice admiral Nishihiko Kojiro launched a surprise attack on the naval base of Dutch Port in the Aleutian Islands, and the battle started. The next day, the Japanese army raided again and the coastal defense facilities were seriously damaged. On June 6th, the Japanese army landed in Chiska (1 250) and Atu (1 200), but they did not resist the occupation of the two islands on July 7th.

However, the Japanese attacked Midway Island. As a result of the Midway naval battle, the Japanese army lost four heavy aircraft carriers (Chicheng, Kaga, Black Dragon and Dragonfly), 1 heavy cruiser, 332 aircraft (280 of which sank with the aircraft carrier), 1 battleship and 654,300 heavy cruisers. There were 3,500 casualties.

The US military lost 1 aircraft carrier ("York City"), 1 destroyer and 150 aircraft (30 of which were destroyed at the midway base) and 307 personnel. In order to recover Artu and Kiska Island in the western Aleutian Islands, the US military launched a landing operation from May to August in 1943. 1June, 942, Japanese troops occupied Artu and Kiska Island. In order to strengthen the defense of the Aleutian Islands, the Japanese army adapted and expanded the North Sea Guard.

By April 1943, the number of Japanese troops stationed in Artu had increased to 2,500, and that in Kiska Island had increased to 6,000. The U.S. military first imposed a sea blockade on the above islands and cut off its ties with Japan, and then decided to recover the two islands under the command of Major General T.C. Kincaid, commander of the Aleutian region.

According to the reconnaissance, the Japanese defense in Atu was weak, so they decided to bypass Kiska Island and attack Atu first. The landing formation is under the command of Major General Rockwell, with three battleships, six cruisers, 19 destroyers, 1 escort carriers and five transport ships, with nearly 250 aircraft as air support. The landing force is the 7th Infantry Division of the United States.

At the dawn of May 1943, 1 1, the US military began to prepare aviation firepower. 10: 30, the 7th division began to land with the support of naval gun fire. One division landed from the north bank of Artu, and the main force landed from the south bank of Masakes Bay. Due to the suppression of American artillery fire, the Japanese troops guarding the island were forced to retreat to the reserve position. Two landing troops of the American army crushed the slight resistance of the Japanese army, and then attacked the north and south. After the rendezvous, they pursued eastward. In the case of isolation and helplessness, the Japanese army resisted with hidden shelters. The American attack was blocked and the progress was slow.

1943 At the end of May, the Japanese army retreated to the northern highlands and was bombarded by American naval guns, causing heavy casualties. At dawn on the 30th, 150, the Japanese army broke into the American position, and the whole army was wiped out. In this campaign, the US army retaken Artu at the cost of 600 deaths 1200 injuries. At the end of June, the US military began to prepare for the aviation and naval gun firepower of Kiska Island.

In view of the isolated situation and difficult defense, the Japanese troops guarding the island gradually withdrew under the cover of dense fog before July 29. Unaware of the Japanese retreat, the US military bombed the island 1 06 times and fired naval guns 15 times from August 15, and landed on the island on August15. In this campaign, the US military recovered the Aleutian Islands for the first time by cross-island attack tactics, which eliminated Japan's threat to the North Pacific and Alaska, kicked off the partial counterattack, and established a forward base to surround and attack Japan.
