Butterfield joined Maj. Gen. George B. McClellan's Army of the Potomac for the Peninsula Campaign in the V Corps, commanded by Maj. Gen. Fitz John Porter. In the Seven Days Battles, at Gaines' Mill on June 27, 1862, he was wounded but demonstrated the bravery that was eventually recognized in 1892, with the Medal of Honor.
