States devoted specifically to astronomy, the Sidereal Messenger, and other works including The Orbs of Heaven (1848 and later), and Popular Astronomy (1860). When the American Civil War broke out, Mitchel turned soldier. He happened to be in New York when the news of the Battle of Fort Sumter came and, being asked to speak at a public meeting, poured out the deep emotions of his fervid soul in a passionate appeal whose eloquence produced an effect like that of the orations or Demosthenes, Cicero, and Burke. Men and women wept aloud; the cheering drowned his words and the speech he made has been regarded as worthy to be placed alongside abolitionists Abraham Lincoln, Charles Sumner, Wendell Phillips, and Henry Ward Beecher. His previous record and this address procured for Mitchel and high position in the Army and his career as a soldier began. Civil War During the American Civil War, he entered the Union Army with a commission as brigadier general of volunteers. He first organized the northern Kentucky defenses around Cincinnati. He commanded the Department of the Ohio from September to November 1861. During this time, he conspired with espionage agent James J. Andrews on plans to steal a train in Georgia and disrupt a railroad vital to the Confederate States Army coincident with Mitchel's planned attack on Chattanooga, Tennessee. The raid failed, as did Mitchel's military operation. Andrews and a number of his men were captured. Andrews himself was among eight men who were tried in Chattanooga. They were hanged in Atlanta by Confederate forces, but were later buried in the National Cemetery at Chattanooga in 1887. Although a military failure, the story of Andrew's Raid became known to American history as the Great Locomotive Chase, and has been retold in publications and film. The pursuit of Andrews' Raiders formed the basis of the Buster Keaton silent film The General and a dramatic 1956 Walt Disney film, The Great Locomotive Chase. Mitchel led a division in the Army of the Ohio from December 1861 to July 1862, and was placed in charge of the defense of Nashville, Tennessee, with headquarters in the vicinity of Shelbyville, Tennessee. He became famous when he seized the city of Huntsville, Alabama in April 1862 without a shot being fired, after he led his troops there from Shelbyville in a surprise maneuver. He was promoted to major general for his efforts. In
