Stephen A. Douglas
In 1861, he was given command of the Army of the Potomac. He was a student of West Point and dubbed the name “Young Napoleon”. He had experience with war during the Mexican War and observed during Crimean War in Russia. He was good at organizing his army and drilling it, but he never found his army to be ready for fighting. He continued to drill without moving his army toward Richmond. He was given the nickname “Tardy George”.
