NORTHFIELD (AP) -- The Sullivan Museum and History Center at Vermont’s Norwich University is going to be hosting a new exhibition in its Civil War series.

The title of the exhibit that opens Jan. 13 will be "1864: Some Suffer So Much."

Norwich is the nation’s oldest private military college.

The exhibit will tell the stories of Norwich alumni during the bloody Civil War year of 1864.

It will examine the role of military surgeons who treated wounded soldiers on the battlefields and in the three Vermont Civil War hospitals in Brattleboro, Burlington and Montpelier. It also traces the history of post-traumatic stress disorder from the Civil War to the present.

Norwich alumni played a significant role in the United States Colored Troops, African American combat units that fought in 1864.
