Philip Henry Sheridan was a career United States Army officer and a Union general in the American Civil War. His career was noted for his rapid rise to major general and his close association with General-in-chief Ulysses S. Grant, who transferred Sheridan from command of an infantry division in the Western Theater to lead the Cavalry Corps of the Army of the Potomac in the East. In 1864, he defeated Confederate forces under General Jubal Early in the Shenandoah Valley and his destruction of the economic infrastructure of the Valley, called "The Burning" by residents, was one of the first uses of scorched-earth tactics in the war. In 1865, his cavalry pursued Gen. Robert E. Lee and was instrumental in forcing his surrender at Appomattox Courthouse.

Ulysses S. Grant was an American military officer, politician, and the 18th president of the United States from 1869 to 1877. As commanding general, Grant led the Union Army to victory in the American Civil War in 1865 and briefly served as U.S. secretary of war. An effective civil rights executive, Grant signed a bill to create the Justice Department and worked with Radical Republicans to protect African Americans during Reconstruction.
