“Just beyond a strip of woods about 100 yards behind the John Otto farmhouse are the remains of the farmer's bank barn. After the Battle of Antietam on Sept. 17, 1862, farmer Otto's house and barn were used as makeshift field hospitals by the Union army. Many wounded soldiers from the 16th Connecticut were first treated here after the battle. 16th Connecticut private Henry Tracy, who did not participate in the battle because of severe sunstroke, was detailed to serve as a nurse here. He was responsible for 80 wounded men.”
