After a year-long struggle with throat cancer, surrounded by his family, Grant died at 8:08 a.m. in the Mount McGregor cottage on July 23, 1885, at the age of 63. Sheridan, then Commanding General of the Army, ordered a day-long tribute to Grant on all military posts, and President Grover Cleveland ordered a thirty-day nationwide period of mourning. After private services, the honor guard placed Grant's body on a special funeral train, which traveled to West Point and New York City. A quarter of a million people viewed it in the two days before the funeral. Tens of thousands of men, many of them veterans from the Grand Army of the Republic (GAR), marched with Grant's casket drawn by two dozen black stallions to Riverside Park in the Morningside Heights neighborhood of Upper Manhattan. His pallbearers included Union generals Sherman and Sheridan, Confederate generals Simon Bolivar Buckner and Joseph E. Johnston, Admiral David Dixon Porter, and Senator John A. Logan, the head of the GAR. Following the casket in the procession were President Cleveland, the two living former presidents Hayes and Arthur, all of the President's Cabinet, as well as the justices of the Supreme Court.
