January 2012 ** An interesting account of the army training camp and prisoner of war camp in Indianapolis during the American Civil War. This was of particular interest to me because I live in the neighborhood now known as Herron-Morton and my home is on ground that once was covered by the tents of the guards of Camp Morton.
However, for a more nuanced and less romanticized version of the camp's history, read Den of Misery
by James R. Hall. He points out that this book is the classic, but was published in a strongly patriotic time and was based primarily on newspaper accounts, which portrayed the camp in mostly positive terms.
