From the Richmond Examiner, 7/21/1863
A NEGRO SOLDIER DISCOVERED. – The prison officials, while engaged in paroling the prisoners on Belle Isle, in order to send a body away by flag of truce, discovered among the enlisted men a negro, who had cropped his kinky hair short, and by the aid of a light olive complexion, and a regulation uniform, had escaped notice. He gave the name of Hascall, (intended rascal,) and said he enlisted in Massachusetts. The black sheep was removed from the white flock, and provided with quarters becoming his importance.
