The whole world of the Nisei- American-born Japanese- was destroyed on the day Pearl Harbor was attacked. Bill Hosokawa tells of the events that led up to the unprecedented wholesale evacuation of 110,000 Japanese Americans to internment camps, the way the evacuation decision was reached, how the Nisei fought to avert it; life in the evacuation camps, how the decision was reached to form a Nisei combat battalion, and to use other Nisei for intelligence work in the Pacific, and how their heroism helped to win acceptance for all Japanese Americans.
