Gen. Philip Sheridan's troops dealt a major blow to Robert E. Lee's Confederate army on April 6, capturing nearly a quarter of his men. At Appomattox Court House on April 9, 1865, Sheridan blocked Lee's escape. Gen. Ulysses S. Grant wrote of Sheridan that he "has no superior as a general, either living or dead, and perhaps not an equal."
