George B. McClellan
A portion of the Julian Scott portrait of McClellan in the National Portrait Gallery in Washington, D.C. George Brinton McClellan (December 3, 1826 – October 29, 1885) was a major general during the American Civil War and the Democratic presidential nominee in 1864, who later served as Governor of New Jersey. He organized the famous Army of the Potomac and served briefly (November 1861 to March 1862) as the general-in-chief of the Union Army. Early in the war, McClellan played an important role in raising a well-trained and organized army for the Union. Although McClellan was meticulous in his planning and preparations, these characteristics may have hampered his ability to challenge aggressive opponents in a fast-moving battlefield environment. He chronically overestimated the strength of enemy units and was reluctant to apply principles of mass, frequently leaving large portions of his army unengaged at decisive points. McClellan's Peninsula Campaign in 1862 ended in failure, with retreats away from attacks by General Robert E. Lee's Army of Northern Virginia and an unfulfilled plan to seize the Confederate capital of Richmond. His performance at the bloody Battle of Antietam blunted Lee's invasion of Maryland, but allowed Lee to eke out a precarious tactical draw and avoid destruction, despite being outnumbered. As a result, McClellan's leadership skills during battles were questioned by President Abraham Lincoln, who eventually removed him from command, first as general-in-chief, then from the Army of the Potomac. Lincoln offered this famous evaluation of McClellan: "If he can't fight himself, he excels in making others ready to fight." Indeed, McClellan was the most popular of that army's commanders with its soldiers, who felt that he had their morale and well-being as paramount concerns. General McClellan also failed to maintain the trust of Lincoln, and proved to be frustratingly derisive of, and insubordinate to, his commander-in-chief. After he was relieved of command, McClellan was the unsuccessful Democratic Party nominee opposing Lincoln in the 1864 presidential election. The effectiveness of his campaign was damaged when he repudiated his party's anti-war platform, which promised to end the war and negotiate with the Confederacy. He served as the 24th Governor of New Jersey from 1878 to 1881. He eventually became a writer, defending his actions during the Peninsula Campaign and the Civil War. The majority of modern authorities have assessed McClellan as a poor battlefield general. However, a small faction of historians maintain that he was a highly capable commander, whose reputation suffered unfairly at the hands of pro-Lincoln partisans who needed a scapegoat for the Union's setbacks. His legacy therefore defies easy categorization. After the war, Ulysses S. Grant was asked to evaluate McClellan as a general. He replied, "McClellan is to me one of the mysteries of the war."
