" Under standing orders from General Lee, the Army of Northern Virginia enslaved any and all black persons it could seize—in Virginia, Maryland, even Pennsylvania during the Gettysburg Campaign. It made no distinctions between those who had escaped during the war, those born free, or those freed before the war under the laws of Southern states. If they were black, the men in gray took them as property. "
