Fort Henry (Stewart County, Tennessee)
Stewart County · Tennessee · Civil War
History & Significance
Named for Confederate Senator Gustavus Henry of nearby Clarksville, this poorly positioned earthen field fortification was laid out on low ground by Tennessee state engineers and constructed in the summer of 1861 to defend the Tennessee River and the critical railroad route between Bowling Green, Kentucky, and Memphis. Construction began in mid-June, using men from the 10th Tennessee Infantry and slaves, with the first cannon test fired on July 12, 1861.
The fort's placement proved fatally flawed: situated on low, swampy ground and dominated by hills across the river, it developed into frequent flooding during rains or high tide, with more than half the fort underwater on some occasions, including most of its armory. The fort with its seventeen mounted guns and adjacent entrenched garrison camp became the scene of the first major Union victory in the western theater on February 6, 1862, defended by fewer than 3,400 ill-equipped Confederate soldiers under Brigadier General Lloyd Tilghman, largely inundated by floodwaters.
Brigadier General Ulysses S. Grant commanded 15,000 troops supported by Flag Officer Andrew H. Foote's seven gunboats; Tilghman quickly recognized the futility of his position and sent all but 70 artillerymen overland to reinforce nearby Fort Donelson. The victory belonged to the navy; Grant's foot soldiers, delayed by weather and muddy roads, did not join the fighting, and Foote breached the Confederate line with surprising ease, opening the Tennessee River to northern Alabama.
With the fall of Fort Henry, Union forces outflanked the major Confederate defensive bastion at Columbus, Kentucky, on the Mississippi River and opened West Tennessee to Union invasion and occupation. Fort Henry demonstrated that the Civil War in the West would be fought largely for control of the rivers—antebellum commercial arteries that became wartime barriers to effective Confederate unity and Union avenues for military, political, and economic reconstruction.
