World War II: Japanese on American soil

Frank Gartz's best friend, Frank Von Arx, writes to him from his post in the Aleutian Islands, Alaska. Besides the usual wry humor, this letter contains little-known information about the World War II Japanese invasion of the Aleutian Islands, Alaska. It was the first time the Japanese had invaded American soil since the War of 1812. I had known nothing about the battles of Attu and Kiska before reading this letter and looking into the history.
