Fort Leavenworth in Leavenworth County, Kansas — The American Midwest (Upper Plains)
Fort Sully
During the Civil War, Fort Leavenworth functioned as an arsenal, a supply base, and a training and organizational camp for volunteer troops. A series of defensive earthworks was constructed on a hill overlooking the National Cemetery. The position was fortified with these two 24 pound seige and garrison guns mounted within the works as the fort's primary armament along with field gun emplacements and rifle pits. Although technically a battery, the entire complex was named Fort Sully after Brigadier General Alfred Sully who had been stationed at Fort Leavenworth at the outbreak of the war. Two more gun positions were constructed just South and West of the main parade and post hospital. All these positions were abandoned at the end of the Civil War.
