This is a portrait of a young man in a Union Army camp during the Civil War, circa May 1863, in Virginia. He is probably a former slave who found work with the army. A high-resolution version of the image is here. The caption at the bottom of the picture reads “Dick Sketched on the 6th of May, the afternoon of Gen. Hookers retreat across the Rappahannock.” This was after the Battle of Chancellorsville, where forces led by Union General Joseph Hooker were beaten by Confederate forces led by Generals Robert E. Lee and Stonewall Jackson.
