"A River Unvexed: A History and Tour Guide of the Campaigns for the Mississippi River." by Jim Mills, p. 452 "Soldiers in the Confederate trenches were not only eating mule and ratmeat, but one Missouri regiment reportedly consumed a camel. During Jefferson Davis' tenure as Secretary of War, he had recomended that the Army experiment with using camels in place of horses and mules in the arid west. A number were imported from Egypt, but the effort came a cropper. The survivor of the failed experiment, "a quiet peaceable fellow, and a general favorite" with the men, reported Col. Robert S. Bevier, had been killed by a Union sniper. The men's reaction to camel steaks apparently went unrecorded."

"History, 31st Regiment, Illinois Volunteers, Organized by John A. Logan". "After the surrender of Vicksburg, the regiment went into camp on a hill inside the Confederate lines and to the northwest of Fort Hill (3rd Louisiana Redan) overlooking the graveyard road. Along this valley road supplies were passed from Vicksburg to Pemberton's left wing during the siege. In this valley our sharpshooters had killed 'Price's Camel' used as a pack animal by the Confederates. His skeleton was picked up and his bones made into finger rings and other ornaments and sold to curiosity hunters from the North. When the supply was exhausted, the bones of cattle slain for beef were substituted, the souvenir fiend being fully satisfied they were part of 'Price's Camel'."
