Ulysses S. Grant
Born Hiram Ulysses Grant, at the outbreak of the Civil War, Grant was working in his father's leather store in Galena, Illinois. He was appointed by the Governor to command an unruly volunteer regiment. Grant whipped it into shape and by September 1861 he had risen to the rank of brigadier general of volunteers.
He sought to win control of the Mississippi Valley. In February 1862 he took Fort Henry and attacked Fort Donelson. When the Confederate commander asked for terms, Grant replied, "No terms except an unconditional and immediate surrender can be accepted." The Confederates surrendered, and President Lincoln promoted Grant to major general of volunteers.
At Shiloh in April, Grant fought one of the bloodiest battles in the West. President Lincoln fended off demands for his removal by saying, "I can't spare this man--he fights."
For his next major objective, Grant maneuvered and fought skillfully to win Vicksburg, the key city on the Mississippi, and thus cut the Confederacy in two. This was the culmination of one of the most brilliant military campaigns of the war. With the loss of Pemberton's army and this vital stronghold on the Mississippi, the Confederacy was effectively split in half. Grant's successes in the West boosted his reputation, leading ultimately to his appointment as General-in-Chief of the Union armies. Then he broke the Confederate hold on Chattanooga.
Lincoln appointed him General-in-Chief in March 1864. Grant directed Sherman to drive through the South while he himself, with the Army of the Potomac, pinned down Gen. Robert E. Lee's Army of Northern Virginia.
Finally, on April 9, 1865, at Appomattox Court House, Lee surrendered. Grant wrote out magnanimous terms of surrender that would prevent treason trials.
Robert E. Lee
Politically, Robert E. Lee was a Whig. Ironically, he was attached strongly to the Union and to the Constitution. He entertained no special sympathy for slavery.
When Virginia withdrew from the Union, Lee resigned his commission rather than assist in suppressing the insurrection. His resignation was two days following the offer of Chief of Command of U.S. forces under Scott. He then proceeded to Richmond to become Commander-in-Chief of the military and naval forces of Virginia. When these forces joined Confederate services, he was appointed Brig. Gen. in the Regular Confederate States.
Lee returned to Richmond in March of 1862 to become military advisor to President Davis. Whenever he had a plan, General Lee took the initiative and acted at once. Cutting off supplies and reinforcements executed by Jackson at Seven Pines was a successful Confederate venture. He also stopped McClellan's threat to Richmond during the Seven Days Battle - June 26-July 2, 1861. At the Battle of Second Manassas, Lee defeated Pope. At the Battle of Antietam, his Northern thrust was checked by McClellan; however, he repulsed Burnside at Fredericksburg in December of 1862. In May of 1863, Gen. Lee defeated Gen. Hooker at Chancellorsville, but was forced onto the strategic defensive after Gettysburg in July. On April 9, 1865, Lee surrendered to Ulysses S. Grant at the village of Appomattox Court House.
