The 522nd Field Artillery Battalion was activated in 1943 as part of the famed 442nd Regimental Combat Team (RCT) and served as fire support during key moments in the European Theater including the battle at Hill 140, the liberation of Bruyères and the rescue of the 141st Infantry Regiment’s “Lost Battalion.”
The unit then split from the 442nd RCT and supported various infantry divisions to break the Siegfried Line, also liberating survivors from some satellite camps of the Dachau Concentration Camp.
