General McClellan :D
Little Mac was Major General George Brinton McClellan who was in the Union Army. He was the Commander of the Army of the Potomac and he would later be the Democratic candidate for the presidency of the United States in the 1864 elections.
As the new Union General in Chief George B. McClellan was making plans in the East for the Army of the Potomac, General McClellan did not neglect the Western Theater. He appointed General Don Carlos Buell to head the Department of Ohio, and General Henry W. Halleck to head the Department of Missouri. As an aside, at the time, little did both McClellan nor Halleck know that before the year of 1862 was over, Halleck would replace McClellan as general in chief.
When General George B. McClellan assumed command of the Army of the Potomac, a replacement was needed for the Ohio Department. General William S. Rosecrans was selected. He was a West Point graduate and a soldier of known competence.
He was called Little Mac and the Young Napoleon. Part of the reason for this was that McClellan was a student of the Napoleonic wars, and that his intellect was high as was Napoleon's. He was called Little Mac and the Young Napoleon by the Union side in the war. He was known in the south as "The Virginia Creeper" after his performance during the Peninsula Campaign.
Lincoln's response to General McClellan's command was that Lincoln relieved McClellan of Command.
