Aleutian Islands Campaign - Japanese Attack

Japanese Attack

Before Japan entered World War II, its navy had gathered extensive information about the Aleutians, but it had no up-to-date information regarding military developments on the islands. Admiral Yamamoto provided the Japanese Northern Area Fleet, commanded by Vice-Admiral Boshiro Hosogaya, with a force of two small 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 to the west. Hosogaya was instructed to destroy whatever American forces and facilities were found on Adak—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 west of Adak, the other on the Aleutian's westernmost island, Attu, 180 miles west from Kiska.

Because United States Naval intelligence had broken the Japanese naval codes, Admiral Nimitz had learned by May 21, of Yamamoto's plans, including the Aleutian diversion, the strength of both Yamamoto's and Hosogaya's fleets, and that Hosogaya would open the fight on 1 June or shortly thereafter.

As of June 1, 1942, United States 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 west of Cold Bay, and the recently built Fort Glenn Army Airfield 70 miles 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 2 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 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.

Famous quotes containing the words japanese and/or attack:

    I am a lantern—
    My head a moon
    Of Japanese paper, my gold beaten skin
    Infinitely delicate and infinitely expensive.
    Sylvia Plath (1932–1963)

    ...I believed passionately that Communists were a race of horned men who divided their time equally between the burning of Nancy Drew books and the devising of a plan of nuclear attack that would land the largest and most lethal bomb squarely upon the third-grade class of Thomas Jefferson School in Morristown, New Jersey.
    Fran Lebowitz (b. 1950)
