The earliest known still-existing listing of those buried at this cemetery is known as the "1917 Harper's List." For many years, the cemetery sat forgotten by history. In 1984 Towanna Spivey, an archeologist and curator of the Fort Sill National Landmark and Museum, completed a scientific investigation of records and the site. He identified 64 persons buried in that cemetery by name, but another 50 graves were listed as unknown. Out of respect, none of the remains have ever been dug up or disturbed. Activities today A detachment of the United States Marine Corps, consisting of a firing battery and commanded by a colonel, is stationed at Fort Sill. Referred to as the MARDET, the detachment works with the Field Artillery School to train Marine artillerymen. Marines also serve as gunnery and fire support instructors at the Army Basic Officer Leader Course & Marine Field Artillery Officer Basic Course, and as small group leaders at the Field Artillery Captains' Career Course. All Marine artillery officers attend the Field Artillery School, but are trained in separate classes from their Army counterparts. The 77th Army Band (Special designation: "The Pride of Fort Sill") is part of the Fires Center of Excellence. It was originally organized on 1 March 1907 at Fort Du Pont, Delaware as the 13th Band, Coast Artillery. Another special detachment is the Field Artillery Half Section, an eight-man group representative of the "flying artillery" which was drawn by a team of horses (the Half Section has eight horses – all named after former commanding generals of Fort Sill) around the turn of the 20th century. The Half Section was established in 1969 to celebrate Fort Sill's Centennial. The Soldiers are volunteers for the show group, while the horses, their equipment and transportation are provided through charitable donations. The popular Half Section has appeared in regional parades, local festivities, change of command ceremonies and a presidential inauguration parade. In June 2019, it was announced that the base was to be used for temporary shelter for recent immigrant children. The same facility was used in 2014 by the Obama administration for the same purpose. On July 28th, 2019, the U.S. Department of Health and Human Services announced cancellation of preparations due to public criticism from local communities and a decline in the number of referrals of undocumented youth.
