The correct answer is C, Robert E. Lee.
The secession of Virginia and the beginning of the Civil War took to Lee, who always showed a great fidelity by its native state, to leave its position in the federal army and to become the commander-in-chief of the Virginian troops. In June of 1861, with the rank of general of the Confederate army, he became military adviser to Jefferson Davis, President of the Confederation. He took command of the Army of Northern Virginia in 1862, launching an offensive by which he rejected the threat of the federal army of the Potomac over Richmond, and then defeated Pope in the Second Battle of Manassas.
He suffered his first major defeat at Gettysburg, in 1863. With his decimated army, he resisted the subsequent offensive of Ulysses S. Grant on Richmond, causing fifty thousand casualties to the Union. With the departure of William T. Sherman over Georgia and South Carolina, Robert E. Lee was appointed head of all the Confederate forces, and tried to withdraw his army to join him to Johnston, but was fenced off and forced to surrender at Appomattox on April 9, 1865. After the war, Lee became one of the leading advocates of national reconciliation.
