Major Henry Wirz, the superintendent of a prison camp in Andersonville, Georgia, is hanged, becoming one of only three American Civil War soldiers executed for war crimes.

Henry Wirz was a Swiss-American convicted war criminal who served as a Confederate Army officer during the American Civil War. He was the commandant of Andersonville Prison, a Confederate prisoner-of-war camp near Andersonville, Georgia, where nearly 13,000 Union Army prisoners of war died as a result of inhumane conditions. After the war, Wirz was tried and executed for conspiracy and murder relating to his command of the camp; this made the captain the highest-ranking soldier and only officer of the Confederate Army to be sentenced to death for crimes during their service. Since his execution, Wirz has become a controversial figure due to debate about his guilt and reputation, including criticism over his personal responsibility for Andersonville Prison's conditions and the quality of his post-war trial.

Hanging is killing a person by suspending them from the neck with a noose or ligature. Hanging has been a standard method of capital punishment since the Middle Ages, and has been the primary execution method in numerous countries and regions. As a form of execution, it is commonly practiced at a structure called a gallows. The first known account of execution by hanging is in Homer's Odyssey. Hanging is also a common method of suicide.

The American Civil War was a civil war in the United States between the Union and the Confederacy, which was formed in 1861 by states that had seceded from the Union. The central conflict leading to war was a dispute over whether slavery should be permitted to expand into the western territories, leading to more slave states, or be prohibited from doing so, which many believed would place slavery on a course of ultimate extinction.
