Camp Floyd Cemetery was established in 1858 and abandoned three years later when the troops stationed at Camp Floyd returned to fight in the Civil War. The actual number, location, and identities of soldiers buried there are not known with certainty because the Army did not keep burial records during this period and all surface evidence of grave locations was destroyed. Efforts to commemorate the cemetery included a monument dedicated by the War Department in 1913 and 84 granite markers placed by the American Legion in 1960. Army records later revealed that almost half of the names on those markers were of individuals who died someplace other than Camp Floyd or were never with Johnston's Army. A list of possible burials was reconstructed from army records of soldiers who died at Camp Floyd, but no list of civilians could be found. Ground penetrating radar in 2009 revealed 33 burials and one double burial, though it may not have detected all possible burials. New headstones were placed in 2011 at the locations of the known burials and read "Unknown" to reflect that the identity of the burial is not known.
