Legacy
One of Grant's most trusted lieutenants

Short, fierce and relentless, Philip Sheridan became one of Ulysses S. Grant's most trusted commanders. He crushed Confederate resistance in the Shenandoah Valley, helped run Lee's army to ground at Appomattox, and after the war carried the same hard hand into the wars against the Native nations of the Plains, a record now remembered with that darkness.

Rise of a fighter

Born in 1831, Sheridan rose rapidly1 in the Civil War through sheer aggression, from an infantry commander in the West to chief of cavalry1 for Grant's armies in the East. Grant valued his drive, and gave him independent command in 18642.

The Shenandoah and Appomattox

Sent to clear the Shenandoah Valley, Sheridan defeated Confederate forces there and then systematically destroyed its farms and supplies to deny them to the enemy1, a campaign remembered as 'The Burning.' In the war's final days his cavalry blocked Lee2's line of retreat, helping force the surrender at Appomattox in April 1865.

The Indian Wars

After the war Sheridan rose to command the army in the West and directed much of the campaigning against the Plains nations, endorsing harsh winter attacks on villages3 and the destruction of the bison herds that sustained them1. He became Commanding General of the Army before his death in 1888.1 His Civil War generalship is widely admired; his role in the Indian Wars is judged far more critically today.
