There were 953 Amache internees who served in the segregated Japanese American 442nd Regimental Combat Team, 100th Infantry Battalion, or the Military Intelligence Service (MIS), during WWII. This number was nearly ten percent of the people at Amache and the highest percentage of all the internment centers. Thirty-one Amache men gave their lives in the war, including one Medal of Honor recipient, and their names are inscribed on a monument at the Amache cemetery.
Thirty-two became language instructors in Army intelligence. The 442nd/100th is the most highly decorated unit for its size and length of service in the history of the U.S. Armed Forces, fighting in Italy, France and Germany, receiving eight Presidential Unit Citations, 21 Medals of Honor, 52 Distinguished Service Crosses 559 Silver Stars, 4,000 Bronze Stars, and 9,486 Purple Hearts.
In April 1945, the 552nd Field Artillery Battalion of the 442nd RCT helped to liberate part of the Dachau death camp. Japanese Americans in the MIS served as interpreters in the Pacific theater and later during the Occupation of Japan; many served in both the 442nd and MIS. In 2010, Congress awarded the Congressional Gold Medal, the nation’s highest civilian award, to the 100th/442nd/MIS. A bronze duplicate of the medal is on display at the Amache Museum in Granada, Colorado.
