Hundreds of Confederate Enfields were picked up on Culp's Hill following the battle of Gettysburg. They had belonged to men of Lt. Gen. Richard Ewell's Second Corps, which had recently standardized on .58 caliber weapons. Here's an excerpt from a letter written by John M. Madden of the 109th Pennsylvania in the Union Twelfth Corps, which fought on Culp's Hill:
September 8, 1863, to his brother. "I have a rifle here now that was laying out on the Gettysburg battlefield and it is a regular Rebel one with sword bayonet and marked C-S-A, still nothing that belongs to our Government or is found on a battlefield can be taken home by anybody unless they are private property and have no Government mark on."
