Little Bighorn Battlefield National Monument preserves the site of the June 25, 1876, Battle of the Little Bighorn, near Crow Agency, Montana, in the United States. It also serves as a memorial to those who fought in the battle: George Armstrong Custer's 7th Cavalry and a combined Lakota-Northern Cheyenne and Arapaho force. Custer National Cemetery, on the battlefield, is part of the national monument.
The first memorial on the site was assembled by Captain George K. Sanderson and the 11th Infantry. They buried soldiers' bodies where they were found and removed animal bones. In his official report dated April 7, 1879, Sanderson wrote:
"I accordingly built a mound out of cord wood filled in the center with all the horse bones I could find on the field. In the center of the mound I dug a grave and interred all the human bones that could be found, in all, parts of four or five different bodies. This grave was then built up with wood for four feet above ground. The mound is ten feet square and about eleven feet high; is built on the highest point immediately in rear of where Gen’l Custer’s body was found..."
Lieutenant Charles F. Roe and the 2nd Cavalry built the granite memorial in July 1881 that stands today on the top of Last Stand Hill. They also reinterred soldiers' remains near the new memorial, but left stakes in the ground to mark where they had fallen. In 1890 these stakes were replaced with marble markers.
