After the Battle of the Little Bighorn in 1876, the U.S. Army created forts in eastern Montana, including one where the north-flowing Tongue River flowed into the east-flowing Yellowstone River. The first fort was known as the Tongue River Cantonment or the Tongue River Barracks and was founded on August 27, 1876. A second, permanent fort was constructed on higher ground two miles to the west of the mouth of the Tongue and this became Fort Keogh.

Custer County is a county located in the southeast part of the U.S. state of Montana. As of the 2020 U.S. census, the population was 11,867. Its county seat and largest town is Miles City. The county was established after the end of the American Civil War (1861-1865), on June 2, 1865, as one of the nine original counties of the new western federal Territory of Montana, which had been formed the previous May of 1864 by the United States Congress, with the approval of 16th President Abraham Lincoln (1809-1865, served 1861-1865). It was originally named Big Horn County of the old Montana Territory, and was renamed on February 16, 1877, in honor of Lieutenant Colonel George Armstrong Custer (1839-1876), commander of the famous 7th Cavalry Regiment of the United States Army, recently massacred and killed in the nearby Battle of the Little Bighorn, in the later portion of the American Indian Wars, the year before in June 1876.
