quote “On May 5, 1863, Vallandigham was arrested as a violator of General Order Number 38. His enraged supporters burned the offices of the Dayton Journal, the Republican rival to the Empire. Vallandigham was tried by a military court on May 6 and 7. Vallandigham’s speech at Mount Vernon, Ohio was cited as the source of the arrest. He was charged by the Military Commission with “Publicly expressing, in violation of General Orders No. 38, from Head-quarters Department of the Ohio, sympathy for those in arms against the Government of the United States, and declaring disloyal sentiments and opinions, with the object and purpose of weakening the power of the Government in its efforts to suppress an unlawful rebellion.”
Vallandigham was a former Congressman and a noted Copper Head. He was arrested by military authorities for inciting soldiers to desert their posts in a time of war.
Lincoln ordered him to be released and sent South to the Confederates.
