Caring for the wounded from the Mississippi to the Potomac

In the upper photograph are soldiers convalescing at Baton Rouge, Louisiana, from their wounds received on the Red River and Port Hudson expeditions, and below is Smith's farm near Keedysville, Maryland, close to where the battle of Antietam was fought in September, 1862. In the course of the day's fierce firing nearly twenty-five thousand men were killed and wounded. It covered a period of about twelve hours; few entrenchments or fortifications of any kind were used by either side. Dr. Bernard, surgeon of the One Hundred and Second New York, was made the chief of all the hospitals. One of the locations of his corps hospitals was on Smith's farm. In the background of the picture is a fine view of South Mountain. In the foreground the men are gathered about a fire.
