The Aleutian Islands campaign was a military campaign conducted by the United States, Canada, and Japan in the Aleutian Islands, part of the Territory of Alaska, in the American Theater and the Pacific Theater of World War II starting on June 3, 1942. In the only two invasions of the United States during the war of a U.S. incorporated territory, a small Japanese force occupied the islands of Attu and Kiska, where the remoteness of the islands and the challenges of weather and terrain delayed a larger American-Canadian force sent to eject them for nearly a year. Successful Japanese invasions of other U.S. territories, which were unincorporated territories, in the western Pacific shortly after the Attack on Pearl Harbor included Wake Island, Guam, and the Philippines. The islands' strategic value was their ability to control Pacific transportation routes as US General Billy Mitchell stated to the U.S. Congress in 1935, "I believe that in the future, whoever holds Alaska will hold the world. I think it is the most important strategic place in the world."
The Japanese reasoned that control of the Aleutians would prevent a possible US attack across the Northern Pacific. Similarly, the US feared that the islands would be used as bases from which to carry out a full-scale aerial attack on US West Coast cities like Anchorage, Seattle, San Francisco, or Los Angeles.
A battle to reclaim Attu was launched on May 11, 1943 and completed after a final Japanese banzai charge on May 29. On August 15, 1943, an invasion force landed on Kiska in the wake of a sustained three-week barrage, only to discover that the Japanese had withdrawn from the island on July 29.
The campaign is known as the "Forgotten Battle" because it has been overshadowed by other events in the war.
Military historians often believe that the Japanese invasion of the Aleutians was a diversionary or feint attack during the Battle of Midway that was meant to draw out the US Pacific Fleet from Midway Atoll, as it was launched simultaneously under the same commander, Isoroku Yamamoto. Some historians have argued against that interpretation and believe that the Japanese invaded the Aleutians to protect their northern flank and did not intend it as a diversion.

Japanese attack
Before Japan entered World War II, the Imperial Japanese Navy had gathered extensive information about the Aleutians but had no up-to-date information regarding military developments on the islands. Admiral Isoroku Yamamoto provided the Japanese Northern Area Fleet, commanded by Vice-Admiral Boshiro Hosogaya, with a force of two non-fleet aircraft carriers, five cruisers, twelve destroyers, six submarines, and four troop transports, along with supporting auxiliary ships. With that force, Hosogaya was first to launch an air attack against Dutch Harbor, then follow with an amphibious attack upon the island of Adak, 480 miles (770 km) to the west. Hosogaya was instructed to destroy whatever American forces and facilities were found on Adak, but the Japanese did not know the island was undefended. Hosogaya's troops were to return to their ships and become a reserve for two additional landings: the first on Kiska, 240 miles (390 km) west of Adak, the other on the Aleutians' westernmost island, Attu, 180 miles (290 km) west from Kiska.
Because the US Naval Intelligence had broken the Japanese naval codes, Admiral Chester Nimitz had learned by May 21 of Yamamoto's plans, including the Aleutian invasion, the strength of both Yamamoto's and Hosogaya's fleets, and Hosogaya's plan to start the fight on June 1 or shortly thereafter.
As of June 1, 1942, the US military strength in Alaska stood at 45,000 men, with about 13,000 at Cold Bay (Fort Randall) on the tip of the Alaskan Peninsula and at two Aleutian bases: the naval facility at Dutch Harbor on Unalaska Island, 200 miles (320 km) west of Cold Bay, and the recently built Fort Glenn Army Airfield 70 miles (110 km) west of the naval station on Umnak Island. Army strength, less air force personnel, at those three bases totaled no more than 2,300, composed mainly of infantry, field and antiaircraft artillery troops, and a large construction engineer contingent, which was used in the construction of bases. The Army Air Force's Eleventh Air Force consisted of 10 B-17 Flying Fortress heavy bombers and 34 B-18 Bolo medium bombers at Elmendorf Airfield, and 95 P-40 Warhawk fighters divided between Fort Randall AAF at Cold Bay and Fort Glenn AAF on Umnak. The naval commander was Rear Admiral Robert A. Theobald, commanding Task Force 8 afloat, who as Commander North Pacific Force (ComNorPac) reported to Admiral Nimitz in Hawaii. Task Force 8 consisted of five cruisers, thirteen destroyers, three tankers, six submarines, as well as naval aviation elements of Fleet Air Wing Four.
When the first signs of a possible Japanese attack on the Aleutians were known, the Eleventh Air Force was ordered to send out reconnaissance aircraft to locate the Japanese fleet reported heading toward Dutch Harbor and attack it with bombers, concentrating on sinking Hosogaya's two aircraft carriers. Once the enemy planes were removed, Naval Task Force 8 would engage the enemy fleet and destroy it. On the afternoon of 2 June, a naval patrol plane spotted the approaching Japanese fleet, reporting its location as 800 miles (1,300 km) southwest of Dutch Harbor. Eleventh Air Force was placed on full alert. Shortly thereafter bad weather set in, and no further sightings of the fleet were made that day.
Before the attack on Dutch Harbor, the Army's 4th Infantry Regiment, under command of Percy E. LeStourgeon, was established at Fort Richardson. Col. LeStourgeon had previously designed a layout of base facilities—such as isolation of weapons and munitions depots—to protect against enemy attack.
Attack on Dutch Harbor
According to Japanese intelligence, the nearest field for land-based American aircraft was at Fort Morrow AAF on Kodiak, more than 600 miles (970 km) away, and Dutch Harbor was a sitting duck for the strong Japanese fleet, carrying out a coordinated operation with a fleet that was to capture Midway Island.
Making use of weather cover, the Japanese made a two-day aerial bombing of the continental United States for the first time in history on Dutch Harbor in the city of Unalaska, Alaska on June 3, 1942. The striking force was composed of Nakajima B5N2 "Kate" torpedo bombers from the carriers Jun'yō and Ryūjō. However, only half of the striking force reached their objective. The rest either became lost in the fog and darkness and crashed into the sea or returned to their carriers. Seventeen Japanese planes found the naval base, the first arriving at 05:45. As the Japanese pilots looked for targets to engage, they came under intense anti-aircraft fire and soon found themselves confronted by Eleventh Air Force fighters sent from Fort Glenn Army Air Field on Umnak. Startled by the American response, the Japanese quickly released their bombs, made a cursory strafing run, and left to return to their carriers. As a result, they did little damage to the base.
On June 4, the Japanese returned to Dutch Harbor. This time, the Japanese pilots were better organized and prepared. When the attack ended that afternoon Dutch Harbor oil storage tanks were burning, the hospital partly demolished, and a beached barracks ship damaged. Although American pilots eventually located the Japanese carriers, attempts to sink the ships failed because of bad weather setting in that caused the US pilots to lose all contact with the Japanese fleet. However, the weather caused the Japanese to cancel plans to invade Adak with 1,200 men.
Invasion of Kiska and Attu
Main articles: Japanese occupation of Kiska and Japanese occupation of Attu
The Japanese invasions and occupations of Kiska on June 6 and Attu on June 7 1942 shocked the American public, as the continental United States was invaded for the first time in 130 years since 1815 (during the War of 1812). The invading forces initially met little resistance from the local Unangax, also known as Aleuts. Though the U.S. Navy had offered to evacuate Attu in May 1942, the Attuan Unangax chief declined. Little changed for the Unangax under Japanese occupation until September 1942 when Japan's Aleutian strategy shifted. It was at this point that the Unangax were taken to Hokkaido, Japan, and placed in an internment camp.
The invasion of Attu and imprisonment of the local Unangax became the justification for the United States' policy of forcible evacuation of the Unangax in the Aleutian Islands. Unangan civilians were placed in internment camps in the Alaska Panhandle.
Aftermath
The loyal courage, vigorous energy and determined fortitude of our armed forces in Alaska—on land, in the air and on the water—have turned back the tide of Japanese invasion, ejected the enemy from our shores and made a fortress of our last frontier. But this is only the beginning. We have opened the road to Tokyo; the shortest, most direct and most devastating to our enemies. May we soon travel that road to victory.
—Lieutenant General Simon Bolivar Buckner Jr., a few months after the Aleutian Islands Campaign
Although plans were drawn up for attacking northern Japan, they were not executed. Over 1,500 sorties were flown against the Kuriles before the end of the war, including the Japanese base of Paramushir, which diverted 500 Japanese planes and 41,000 ground troops.
The battle also marked the first time that Canadian conscripts were sent to a combat zone in World War II. The government had pledged not to send draftees "overseas", which it defined as being outside North America. The Aleutians were considered to be North American soil, which enabled the Canadian government to deploy conscripts without breaking its pledge. There were cases of desertion before the brigade sailed for the Aleutians. In late 1944, the government changed its policy on draftees and sent 16,000 conscripts to Europe to take part in the fighting.
The battle also marked the first combat deployment of the 1st Special Service Force, but it also did not see any action.
In the summer of 1942, the Americans recovered the Akutan Zero, an almost-intact Mitsubishi A6M2 Zero fighter, which enabled the Americans to test-fly the Zero and contributed to improved fighter tactics later in the war.
Killed in action
During the campaign, two cemeteries were established on Attu to bury those killed in action: Little Falls Cemetery, located at the foot of Gilbert Ridge, and Holtz Bay Cemetery, which held the graves of Northern Landing Forces. After the war, the tundra began to take back the cemeteries and so in 1946, all American remains were relocated as directed by the soldier's family or to Fort Richardson near Anchorage, Alaska. On May 30, 1946, a Memorial Day address was given by Captain Adair with a 21-gun salute and the sounding of Taps. The Decoration of Graves was performed by Chaplains Meaney and Insko.
Veterans
The 2006 documentary film Red White Black & Blue features two veterans of the Attu Island campaign, Bill Jones and Andy Petrus. It is directed by Tom Putnam and debuted at the 2006 Locarno International Film Festival in Locarno, Switzerland, on August 4, 2006.
Dashiell Hammett spent most of World War II as an Army sergeant in the Aleutian Islands, where he edited an Army newspaper. He came out of the war suffering from emphysema. As a corporal in 1943, he co-authored The Battle of the Aleutians with Cpl. Robert Colodny under the direction of Infantry Intelligence Officer Major Henry W. Hall.
Legacy
Many of the United States locations involved in the campaign, either directly or indirectly, have been listed on the National Register of Historic Places, and several have been designated National Historic Landmarks. The battlefield on Attu and the Japanese occupation site on Kiska are both National Historic Landmarks and are included in the Aleutian Islands World War II National Monument. Surviving elements of the military bases at Adak, Umnak, and Dutch Harbor are National Historic Landmarks. The shipwrecked SS Northwestern, badly damaged during the attack on Dutch Harbor, is listed on the National Register, as is a crash-landed B-24D Liberator on Atka Island.
