(June 25th 1876), Surveyed and drawn under the personel supervision of Lieut. Edward Maguire, Corps of Engineers U.S.A. by Sergeant Charles Becker Co. "D" Battalion of Engineers.
In 1873, the War Department issued instructions that an engineer was to map every reconnaissance. Thus, a topographic engineer was included within each of the three main columns converging on northern Wyoming and southern Montana. Lt. Maguire was included in Terry's column, but accompanied Col. Gibbon after Terry and Gibbon separated. The map was drawn on June 27, while others buried the bodies of Custer's units. The map was then included in an appendix to Maquire's annual report and was later published in Mercator's World Magazine. The bodies of officers were marked by upright stakes or boards reflected in the above map.
