Dutch Harbor
The Battle of Dutch Harbor took place on June 3–4, 1942, when the Imperial Japanese Navy launched two aircraft carrier raids on the Dutch Harbor Naval Operating Base and U.S. Army Fort Mears at Dutch Harbor on Amaknak Island, during the Aleutian Islands Campaign of World War II. The bombing marked the first aerial attack by an enemy on the continental United States, and was the second time in history that the continental U.S. was bombed by someone working for a foreign power, the first being the accidental bombing of Naco, Arizona in 1929.
