Military Service Note
Grant, Ulysses S. 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 and came out less well. 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. 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. (From http://www.whitehouse.gov)
