Mansfield Avenue heads across the northern part of the battlefield between the Poffenberger Farm and the former site of the North Woods, cut down in the century and a half since the battle but currently under restoration. It was named for Union Major General Joseph Mansfield, who was mortally wounded commanding the Union 12th Corps at Antietam, the highest ranking officer killed in the battle. His monument is on Smoketown Road.

The north end of the battlefield was the staging area for Hooker’s 1st Corps, which moved across Antietam Creek on the evening of September 16 and took up positions here. In the morning Hooker’s men attacked to the south across the Miller farm and into the Cornfield. In the end the attack was thrown back, the 1st Corps was fought out, and Hooker himself left the field with a wound to his foot.
