Fort Donelson, a Confederate stronghold near Dover, Tennessee, was built in 1862 to dominate the Cumberland River, a crucial waterway for the Confederacy. Its capture by Union forces under Ulysses S. Grant in February 1862 marked a turning point in the Western Theater, ensuring Union control of the river and undermining Confederate defenses. Authors such as Ann S. Stephens vividly portrayed the fort’s siege as a “game of death,” while John G.
Nicolay highlighted its strategic intricacy, pointing to its powerful artillery and strong garrison. Grant himself stressed the need for the assault, acknowledging the fort’s role in splitting the Confederacy. Charles Carleton Coffin’s firsthand account captured the turmoil of battle, from cannon fire to the final surrender. These diverse viewpoints underscore Fort Donelson’s symbolic and military importance, securing its status as a key location in the Union’s effort to gain control of the Mississippi River.
