The Grand Review of the Armies, held in Washington, D.C., on May 23–24, 1865, was a massive celebration marking the end of the Civil War. Tens of thousands of Union soldiers marched down Pennsylvania Avenue in a two‑day spectacle that symbolized national reunification and the scale of the Union victory. General Philip Sheridan and his cavalry took part in the procession, riding before cheering crowds. Within weeks, Sheridan would be sent to the Texas frontier to oversee operations related to French intervention in Mexico, but he was present for the triumphant review that closed the war.
