Other Markers at Washington Navy Yard Pertaining to the Civil War: Second Officer's House

From HMdb.

SECOND OFFICER'S HOUSE.

The second Officer's House or Quarters B is believed to have elements of an 18th century farmhouse.  This structure was erected as a two-and-a-half story Federal style brick house late in 1801.

It escaped destruction when the British invaded Washington, D.C., in the War of 1812 in 1814 and was substantially altered and enlarged in the later 19th century.  It was used as barracks for Union troops during the Civil War, but returned to its original function as home of the Yard's second ranking officer after the war.

Most recently it has been occupied by the Senior Flag Officer  stationed in the Washington area.

George Washington University-- Part 2: Barracks and Hospital During the War

During the Civil War most of the students left the school to join the Confederacy.  The buildings were used as barracks and a hospital.  Walt Whitman was among the many volunteers to serve here.

In 1873, Columbia College became Columbia University and moved to the urban downtown location centered on 15th Street and H Street, Northwest

In 1904, the school moved to Foggy Bottom and in 1912 to its present location thanks to the efforts of Maxwell Van Zandt Woodhull.
