Shelling the rebel works on the Chickahomy [sic] across the Mechanicsville bridge

Union artillerymen direct their shells at Confederate troops assembled across the Chickahominy River during the Battle of Mechanicsville, which took place on June 26, 1862, and marked the beginning of the Seven Days' Campaign. This pencil sketch was made by Alfred R. Waud, the London-born artist who served as a war correspondent for Harper's Weekly.
