Japanese occupation of Attu
The Japanese occupation of Attu (Operation AL) was the result of an invasion of the Aleutian Islands in Alaska during World War II. Imperial Japanese Army troops landed on 7 June 1942, the day after the invasion of nearby Kiska. Along with the Kiska landing, it was the first time that the continental United States was invaded and occupied by a foreign power since the War of 1812. The occupation ended with the Allied victory in the Battle of Attu on 30 May 1943.
Although it is not clear how the Navy General Staff requested the Combined Fleet Command to plan the Aleutian Operation (Operation AL) to occupy Attu and Kiska Islands, the Navy General Staff seemed to have acknowledged the necessity of Operation AL in response to the proposition of the Fifth Fleet when considering the attempt to overtake Midway (Operation MI).
The plan of Operation AL was consulted with the Imperial General Headquarters army section on 15 April. In early June, the navy would attack Dutch Harbor and Adak Island, and occupy Kiska Island and Attu Island. The Imperial Japanese Army was reluctant to occupy the Aleutian Islands and responded to the navy on 16 April that they would not dispatch troops to the operation. However, the Doolittle Raid on Japan from the North Pacific on 18 April had a great influence on Operation AL. After the air raids on Japan by the Doolittle bombers, the army acknowledged the need to set up patrol bases on the western Aleutian Islands and agreed on 21 April to dispatch troops.
The Navy General Staff promoted Operation MI and Operation AL with the primary purpose of advancing the bases for patrol line, and the Combined Fleet Command also followed it. In other words, the purpose of Operation AL was to build a patrol network in the North Pacific by establishing bases on Midway, Attu, and Kiska to monitor attacks on Japan mainland by US task forces. At the same time, it was intended to prevent advances of US air bases.
Eventually, it was determined that the Imperial Army would invade Attu Island and the Imperial Navy (Navy Maizuru Third Special Naval Landing Force) would invade Kiska Island. The army established the North Sea Detachment (Hokkai-shitai) on 5 May, headed by Major Matsutoshi Hozumi and consisting of approximately 1,000 men.
The order of operation was announced on 5 May. Hozumi was tasked to secure or destroy key points in the western part of the Aleutian Islands, and to make enemy mobility and air power advance in this area difficult. The finalized plan was to destroy Adak's military facilities and then withdraw. Next, the army troops were to invade Attu while the navy invaded Kiska.
Prior to the landings, air raids from carriers were to destroy the air force at Dutch Harbor.
In May 1942, the Japanese began near-simultaneous campaigns against Midway and the Aleutians, thus beginning the Aleutian Islands campaign. During the Battle of Midway, Japanese forces were repulsed in a decisive action. Meanwhile on 7 June, Japanese naval forces under Boshirō Hosogaya landed troops unopposed at Attu in conjunction with the same forces invading Kiska the previous day. A force consisting of 1,140 infantry under Major Matsutoshi Hosumi took control of the island and captured Attu's population, which consisted of 42 Aleuts and two white Americans, Charles Foster Jones (1879–1942), an amateur radio operator and weather reporter, originally from St. Paris, Ohio, and his wife Etta (1879–1965), a teacher and nurse, originally from Vineland, New Jersey. The village consisted of several houses around Chichagof Harbor on the northeast side of the island.
