John Wesley Powell’s
Fort D Historic Site


In the summer of 1861, four forts were built around the strategic city of Cape Girardeau on the orders of General John Frémont. Designed by German-American engineers from St. Louis, the forts were built by soldiers of the 20th Illinois Infantry, Bissell’s Engineers of the West, and local militia under the direction of Illinois Lt. John Wesley Powell. Powell, who would later gain fame as the explorer of the Grand Canyon, was detached from his regiment by the new general, Ulysses S. Grant, in order to raise a local company to man the forts. This Powell did, and his new Battery F served the forts until leaving for the Tennessee River campaign and the Battle of Shiloh. Of the four earthen forts, only Fort D still exists, an intact survivor thanks to civic action in the 1930’s and is now a city historic site. Fort D is located 5 blocks south of the intersection of Missouri Rte. 74 and Sprigg Street in Cape Girardeau, just west of the Mississippi River bridge.

History & Resources

Construction work on Fort D began on August 6, 1861. Eight months earlier, few would have dreamed that the fort would have been a necessity. Tensions between the non-slave states and the slave states grew during the 1850’s and conflict spread along the Missouri and Kansas border. Secessionists in the southern states feared that a new president might move to control their institution of human slavery.

Historical Reenactment

Civil War sites like Fort D don’t come to life without the dedicated help of volunteer Civil War Reenactors. Civil War reenacting is an exciting and rewarding hobby. Reenactors such as the Turner Brigade members here portray infantry, artillery, engineer, and medical units of Missouri Union volunteers and civilians of the Civil War period. We are a family-oriented group, with members from all around the Missouri – Illinois region.


Fort D is a project of the Cape Girardeau Parks and Recreation Department, the Cape Girardeau Convention and Visitors Bureau, The Turner Brigade Association, and the Civil War Roundtable of Cape Girardeau.

All interpreters and guides are volunteers and funding is provided by donations of visitors and friends.

Donations are necessary to the continued protection and interpretation of this unique Civil War site.
