In the midst of the Battle of Gettysburg, Brigadier General Thomas A. Rowley, U.S.A., was arrested for drunkenness and disobedience and was subsequently court martialed. But what really happened on that chaotic day, and how did it affect Rowley and those around him in the years to come? This volume chronicles Rowley's life, with particular attention to the events of July 1, 1863 and the battle that ended his military career. The author discusses the court martial's questionable guilty verdict and Rowley's reaction to it. Sources include personal letters and diaries of the men who served with and under General Rowley. Pertinent information regarding the military rules of the period is provided in order to reveal how Rowley's case deviated from the norm. Finally, appendices provide a list of Rowley's commands, a roll of the court martial participants and Rowley's personal defense statement
