repeated the offer to Wirz who replied, "Mr. Schade, you know that I have always told you that I do not know anything about Jefferson Davis. He had no connection with me as to what was done at Andersonville. If I knew anything of him, I would not become a traitor against him, or anybody else, even to save my life." Rev. P. E. Bole received the same visitor and later sent a letter to Jefferson Davis, who included it as well as Wirz's reply to Schade in his book, Andersonville and Other War-Prisons (1890). Andersonville quartermaster Richard B. Winder, who was in the prison at the time, also confirmed this episode. Execution Wirz was hanged at 10:32 a.m. on November 10, 1865, at the Old Capitol Prison in Washington D.C., located next to the U.S. Capitol. His neck did not break from the fall, and the crowd of 200 spectators guarded by 120 soldiers watched as he writhed and slowly strangled. Wirz was buried in the Mount Olivet Cemetery in Washington, D.C. Wirz was one of only two men tried, convicted, and executed for war crimes during the Civil War, the other being Confederate guerrilla Champ Ferguson. Confederate soldiers Robert Cobb Kennedy, Sam Davis, and John Yates Beall were executed for spying, and Marcellus Jerome Clarke and Henry C. Magruder were executed for being guerrillas. In 1869, Schade received permission from President Johnson to rebury Wirz's body, which had been buried at the Washington Arsenal alongside the Lincoln assassins. While the body was being transferred, it was discovered that the right arm, and parts of the neck and head, had been removed during autopsy. As of the late 1990s, the National Museum of Health and Medicine still had two of his vertebrae. Controversy The Wirz controversy grew out of the questions remaining after his trial pertaining to guilt and responsibility for multiple deaths of prisoners of war in camps on both sides following suspension of the Dix-Hill Cartel prisoner exchange agreement in July 1863. The Grand Army of the Republic, the United Confederate Veterans, Sons of Confederate Veterans (SCV), and the United Daughters of the Confederacy (UDC), among others, evoked sad memories of Civil War prisoners portraying Wirz either a villain, or a martyr-hero, thus further contributing to the disputation. From 1899 to 1916, sixteen states erected monuments dedicated to the Camp Sumter's prisoners. In response, the United Daughters
