Barry shows that Amos Green (1826-1911) from Paris, Illinois, was a leading lawyer and Peace Democrat (Copperhead). Green saw the War as unjust and Lincoln as a despot who had to be stopped. He wrote vicious denunciations of the administration in local newspapers. He was arrested for sedition in 1862. After his release in August 1862, he became the grand commander of the secret Order of American Knights in Illinois, which fought restrictions on civil liberties. It was was also called the Knights of the Golden Circle and later the Sons of Liberty. Green was funded by the Confederate government to arrange riots at the Democratic National Convention in 1864. Although the riots never materialized, he continued giving antigovernment speeches until he was again arrested in November 1864. After this arrest, he agreed to testify for the government about the activities of the Knights; his testimony implicated others but ignored his own deep involvement in antigovernment plots.
