A historical review is presented of Sloan U.S. Army General Hospital, the second largest Union Army hospital in Vermont, which operated from June 1864 to October 1865. Sloan Hospital later became Vermont College, which in 1972 merged with Norwich University. Sloan Hospital operated during the last year and a half of the Civil War and consisted of about 24 large buildings and a number of satellite structures. During its 16 months of operation, approximately 1,700 Union soldiers were admitted for treatment, most of them Vermonters. Information is provided on the establishment of the hospital, financing the construction costs, site selection, types of illnesses that were treated, operation of the hospital, purchase of the buildings/land after the Civil War by Newbury Seminary, and relocation of the buildings and establishment of Montpelier Seminary in 1868.
