Inscription.
“Fort D,” one of the four forts erected in Cape Girardeau by Union forces in 1861, is the only one preserved. Its site southeast of the town was chosen to command the entire bend of the river southward, and also the river road from downstream.

Inclined embankments were built with ditches on the outside. A rectangular gun emplacement projected diagonally at each corner. These earthworks may still be seen.

The soldiers made a bowling alley on the terreplein of the Fort using huge sticks of wood for pins and 32 pound cannon balls to bowl them over.

During extremely cold weather some of the soldiers dug caves into the steep hillside north of the Fort and became temporarily troglodytes; but most of them decided the extra comfort did not warrant the extra work.

remnant of Missouri’s numerous “city” forts, which were forts surrounding Missouri centers of population during the Civil War. The fort originally consisted of a continuous earthwork called a redan that resembles two sides of a triangle with wings. The third side of the triangle was not made of earth, but rather was a simple wooden palisade wall or fence, of indeterminate height, that served to define the rear of the redan, an area called a gorge.

Located within the earthwork walls is a museum structure, constructed in 1937 by the WPA. This museum was also built to be the meeting house for the American Legion. The style of the building is WPA Rustic. The walls of this structure, locally referred to as the blockhouse, are made of limestone that was salvaged from another building. The foundation is concrete. The roof line of the building resembles a castellated parapet, giving the building a distinct, small-scale castle-like appearance.

army. Fort D is the only surviving fortification built by Union troops in the area during the Civil War.

The fort was saved from development in the early 20th century. The earthworks were repaired by the Works Progress Administration during the 1930s. The stone blockhouse was also built by the WPA in 1936 and has been used for various purposes since.

The first regular Union troops, members of the 20th Illinois Volunteer Regiment, landed in Cape Girardeau on July 6th, 1861. Rumors abounded as to the likelihood of the city being attacked by secessionist forces. Construction work on Fort D began on August 6, 1861, under the direction of Lieutenant John Wesley Powell.
