Irish American General Philip Henry Sheridan, career United States Army officer and a Union general in the American Civil War, dies of heart disease in Dartmouth, Massachusetts, on August 5, 1888.

Sheridan is born in Albany, New York, the third child of six by John and Mary Meenagh Sheridan, immigrants from the parish of Killinkere, County Cavan. Fully grown, he reaches only 5 feet 5 inches in height, a stature that leads to the nickname “Little Phil.” Abraham Lincoln describes his appearance in a famous anecdote, “A brown, chunky little chap, with a long body, short legs, not enough neck to hang him, and such long arms that if his ankles itch, he can scratch them without stooping.”

Sheridan’s career is noted for his rapid rise to major general and his close association with General-in-chief Ulysses S. Grant, who transfers 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 defeats Confederate forces in the Shenandoah Valley and his destruction of the economic infrastructure of the Valley, called “The Burning” by residents, is one of the first uses of scorched earth tactics in the war. In 1865, his cavalry pursues General Robert E. Lee and is instrumental in forcing his surrender at Appomattox Court House.

In later years, Sheridan fights in the Indian Wars of the Great Plains. Comanche Chief Tosahwi reputedly tells Sheridan in 1869, “Me, Tosahwi; me good Injun,” to which Sheridan supposedly replies, “The only good Indians I ever saw were dead.” Sheridan denies he had ever made the statement. Biographer Roy Morris Jr. states that, nevertheless, popular history credits Sheridan with saying “The only good Indian is a dead Indian.” This variation “has been used by friends and enemies ever since to characterize and castigate his Indian-fighting career.” In Bury My Heart at Wounded Knee, Dee Brown attributes the quote to Sheridan but does not provide documentation to support his contention, so the quote may be more apocryphal than real.

Both as a soldier and private citizen, Sheridan is instrumental in the development and protection of Yellowstone National Park. The protection of the Yellowstone area is Sheridan’s personal crusade. He authorizes Lieutenant Gustavus Doane to escort the Washburn Expedition in 1870 and for Captain John W. Barlow to escort the Hayden Expedition in 1871. Barlow names Mount Sheridan, a peak overlooking Heart Lake in Yellowstone, for the general in 1871. As early as 1875, Sheridan promotes military control of the area to prevent the destruction of natural formations and wildlife.

In 1883, Sheridan is appointed general-in-chief of the U.S. Army, and in 1888 he is promoted to the rank of General of the Army during the term of President Grover Cleveland. Sheridan serves as the ninth president of the National Rifle Association.

Sheridan suffers a series of massive heart attacks two months after sending his memoirs to the publisher. After his first heart attack, the U.S. Congress quickly passes legislation to promote him to general and he receives the news from a congressional delegation with joy, despite his pain. His family moves him from the heat of Washington, D.C. and he dies of heart failure in his summer cottage in the Nonquitt section of Dartmouth, Massachusetts.

His body is returned to Washington, and he is buried on a hillside facing the capital city near Arlington House in Arlington National Cemetery. The burial helps elevate Arlington to national prominence.
