The 2d and 10th Infantry were a portion of the force operating in our centre at the battle of Antietam, Maryland. They engaged, two hundred and twenty-five strong, on the 17th of September. I was on duty near the field. The wounded were brought on stretchers to me, and ambulances carried them a couple of miles to the field hospital. The fire was case-shot and musketry, at moderate range. A few primary operations under chloroform, but none of serious character, were performed before the above-mentioned hospital was reached. The casualties numbered eighty-five, or twenty-one per centum.
September 20th, the brigade engaged in a skirmish, following a reconnoissance, near Shepherdstown, Virginia. The wounded were brought over the river and sent to the Antietam hospitals. I assisted in a primary operation at the upper third of the thigh for severe compound fracture from a minie ball. Death resulted next day. While lying in camp near Sharpsburg, the 7th Infantry joined the brigade and was assigned to my care.
