The Cornfield and the nearby fights it spawned extracted a tremendous cost from both the Army Northern Virginia and the Army of the Potomac. Of the 9,298 men Lee lost at Antietam, roughly 7,000 of those had fallen in fighting on the Union right in or around the Cornfield. McClellan, too, lost most of his men sacrificed at Antietam in fighting around the Cornfield, some 9,913 of his total 12,401 battle casualties. Both Lee and McClellan lost nearly two thirds of their armies in fighting around the Cornfield. D. R. Miller’s cornfield harvest of death had simply bled both armies dry.
