Henry Wirz, Swiss-American captain (b. 1823)

Henry Wirz (born Hartmann Heinrich Wirz, November 25, 1823 – November 10, 1865) was a Swiss-American officer of the Confederate States Army during the American Civil War. He was the commandant of the stockade of Camp Sumter, a Confederate prisoner-of-war camp near Andersonville, Georgia, where nearly 13,000 Union detainees died as result of inhumane conditions. After the war, Wirz was tried and executed for conspiracy and murder relating to his command of the camp.

Since his execution, Wirz has become a controversial figure due to debate about his guilt and reputation, including criticism over his personal responsibility for Camp Sumter's conditions and the quality of his post-war trial.
