This study is about the 442nd Regimental Combat Team during World War II as it assisted VI Corps in the push through the Vosges Mountains in northern France. The 442nd RCT was composed mostly of Japanese-Americans, or Nisei, who volunteered to join the U.S. Army. Behind their contributions were U.S. government policies which precluded Japanese immigrants from citizenship and land ownership, and culminated in the relocation of more than 110,000 Japanese-Americans from the West Coast of the United States. This study briefly examines the Japanese in America, the formation of the 442nd RCT, and its exploits. Its involvement in the campaign through the Vosges Mountains began with its attachment to the 36th Infantry Division on 13 October and ended on 9 November 1944. This study examines the four battles during the campaign to take Bruyeres, Biffontaine, the Rescue of the "Lost Battalion," and the follow-on mission. This study examines the combat and environmental conditions in the Vosges Mountains. It shows military decision-making from the corps level to regiment level and, in some cases, to company level. It provides a balanced review of events to promote historical accuracy.
