This engraving, from a photograph, is of Colonel William Findlay Rogers of the 21st New York Infantry from J.H. Mills’ Chronicles of the Twenty-first Regiment New York State Volunteers (1887).

Rogers was the original Colonel of the 21st, commanded them at Antietam in September 1862, and led them to the end of their term in May 1863. He was later honored by brevet to Brigadier General of Volunteers for his war service.
