Sheridan's aggressive and well-executed performance at the Battle of Sayler's Creek on April 6 effectively sealed the fate of Lee's army, capturing over 20% of his remaining men. President Lincoln sent Grant a telegram on April 7: "Gen. Sheridan says 'If the thing is pressed I think that Lee will surrender.' Let the thing be pressed." At Appomattox Court House, April 9, 1865, Sheridan blocked Lee's escape, forcing the surrender of the Army of Northern Virginia later that day. Grant summed up Little Phil's performance in these final days: "I believe General Sheridan has no superior as a general, either living or dead, and perhaps not an equal."
