Official site
Fort Donelson National Battlefield, located near Dover in Stewart County, Tennessee, with extensions into Calloway County, Kentucky, preserves the sites of a pivotal early Civil War engagement that marked one of the Union Army's first major victories. Established as a national military park on March 26, 1928, and redesignated a national battlefield in 1985, the 600-acre (243 ha) site commemorates the February 1862 Battle of Fort Donelson, where Union forces under Brigadier General Ulysses S. Grant captured a key Confederate stronghold on the Cumberland River, opening vital waterways and thrusting Grant to national prominence. The battlefield encompasses the remnants of three interconnected forts—Donelson, Henry, and Heiman—along with earthworks, river batteries, a national cemetery, and the historic Dover Hotel (Surrender House), offering visitors a tangible connection to the conflict's strategic and human dimensions. Managed by the National Park Service (NPS) as part of the American Battlefield Protection Program, it spans diverse terrain along the Cumberland River (now Lake Barkley), blending preserved Civil War fortifications with Ozark-like woodlands and riverine ecosystems. With around 300,000 visitors annually, the park serves as an educational hub for understanding the war's western theater, emphasizing themes of strategy, sacrifice, and reconciliation. As of September 2025, the park is fully operational, with the Visitor Center open daily (8 a.m.–4:30 p.m., extended in summer) and ongoing programs like ranger-led tours; no major closures or disruptions are reported, though trail conditions may vary with weather.
Fort Donelson National Battlefield occupies a strategically vital position on the Western Highland Rim of the Interior Low Plateaus physiographic province, at the confluence of the Cumberland and Tennessee Rivers (now impounded as Kentucky Lake and Lake Barkley). The core 559-acre (226 ha) Tennessee unit centers on Dover, with the 1,140-acre (461 ha) Fort Henry unit in Kentucky, totaling over 1,700 acres across both states. The landscape features a mix of narrow ridges, steep slopes (up to 200 feet/61 m elevation drops), deep ravines, bottomlands, and floodplains, dissected by the Cumberland River's bends and several small, intermittent streams that required bridging for modern trails. Geologically, the area is underlain by Mississippian-age limestone and shale from ancient seabeds (about 320–360 million years old), overlain by thin loess soils and glacial till from the Pleistocene Ice Age, which contributed to the fertile but erodible terrain used for Confederate earthworks. The river, now a reservoir managed by the U.S. Army Corps of Engineers, provides scenic vistas at summer pool levels, with bluffs offering commanding views that were crucial for 19th-century artillery placements. The park's location in the transitional zone between the Appalachian Highlands and Mississippi Embayment results in a humid subtropical climate: mild winters (average 40°F/4°C), hot summers (85°F/29°C), and 50 inches (127 cm) annual rainfall, fostering lush vegetation but also flood risks that mirror the battle's muddy conditions.
The history of Fort Donelson National Battlefield is inextricably
linked to the American Civil War's Forts Henry and Donelson
Campaign, a bold Union offensive in the war's western theater that
shattered Confederate defenses in the Upper South.
Pre-War
and Construction
The forts were constructed in 1861 by
Confederate forces under Brigadier General Daniel S. Donelson (a
relative of President Andrew Jackson) to control the Cumberland and
Tennessee Rivers, vital arteries for trade and invasion routes. Fort
Henry, on the east bank of the Tennessee River in Kentucky, was a
small earthwork with 17 guns; Fort Heiman, across the river, was an
unfinished hilltop battery; and Fort Donelson, 12 miles east on the
Cumberland near Dover, Tennessee, was the strongest—a 100-acre
complex of earthworks, rifle pits, and 15 heavy guns manned by
16,000 troops under Generals John B. Floyd, Gideon J. Pillow, and
Simon B. Buckner. These fortifications aimed to block Union advances
from Cairo, Illinois, but their low-lying positions proved
vulnerable to naval bombardment and flooding.
The Battle of Fort
Donelson (February 11–16, 1862)
The campaign began on February 6,
1862, when Union gunboats under Flag Officer Andrew H. Foote shelled
Fort Henry into submission after a 75-minute duel, capturing it with
minimal infantry involvement from Grant's 15,000-man force;
Confederates evacuated to Fort Donelson. Grant, promoted to major
general for his initiative, marched 10 miles overland in freezing
rain to invest Fort Donelson with 24,000 troops by February 11.
The battle unfolded in phases:
February 11–13 (Skirmishes and
Siege): Union probes tested Confederate lines; on the 13th,
Brigadier General Charles F. Smith's division seized a key outer
work (Fort Heiman-style position), but heavy rains turned the ground
to mud, stalling advances.
February 14 (Naval Engagement):
Foote's ironclads dueled river batteries in a 90-minute exchange,
wounding Foote and damaging the gunboats, which retreated—boosting
Confederate morale but failing to breach the works.
February 15
(Breakout Attempt): Confederates launched a surprise counterattack
at 5 a.m., led by Pillow and Buckner, nearly routing Grant's right
wing under McClernand, but Union reinforcements (Lew Wallace's
division) and Grant's rally held the line; by noon, Floyd and Pillow
retreated back into the fort, exhausted.
February 16 (Surrender):
Surrounded and starving (rations depleted, temperatures below
freezing), Floyd fled by boat (later drowning in the James River),
Pillow escaped on horseback, and Buckner, an old West Point friend
of Grant's, surrendered the garrison of 12,000–15,000 men—the
largest U.S. surrender until 1942—after Grant's famous demand for
"no terms except unconditional and immediate surrender."
Casualties were heavy: Union ~2,700 (500 killed, 2,100 wounded, 100
missing); Confederate ~13,000 captured, plus 1,500 killed/wounded.
The surrender occurred at the Dover Hotel, now the Surrender House.
Aftermath and Civil War Significance
The victory secured the
Cumberland and Tennessee Rivers for Union supply lines, leading to
the fall of Nashville (February 25) and much of Tennessee/Kentucky,
shifting momentum westward and earning Grant the nickname
"Unconditional Surrender." It boosted Northern morale after Bull Run
defeats and forced the Confederacy to abandon border states, paving
the way for Shiloh and Vicksburg. Post-war, the site became a
national cemetery in 1867 for reinterring Union dead, now holding
670 Civil War soldiers and later veterans. Archaeological surveys
since the 1950s have uncovered rifle pits, cannons, and soldier
artifacts, aiding preservation.

Nestled in the Cumberland River valley, Fort Donelson's ecology
reflects the Eastern Deciduous Forest biome, with human-modified
landscapes recovering to showcase regional biodiversity. The 600-acre
site features oak-hickory dominated hardwood forests on ridges and
slopes, transitioning to riverine bottomlands with sycamore, river
birch, and willow along floodplains and intermittent streams. Over 100
plant species have been cataloged by botanist Dr. Edward W. Chester,
including common wildflowers, ferns, and trees that provide seasonal
color—vibrant fall foliage from oaks and maples, spring wildflowers, and
summer greenery with songbirds. The terrain's diversity—steep ravines,
open fields from old farmsteads, and river bluffs—supports varied
habitats, though invasive species like Japanese honeysuckle and
tree-of-heaven pose management challenges.
Wildlife is abundant yet
subtle: Songbirds (e.g., cardinals, wood thrushes) fill the air in
summer; mammals include white-tailed deer, raccoons, opossums, and
occasional coyotes; reptiles like box turtles and copperheads inhabit
the understory; and aquatic life in the Cumberland (e.g., catfish, bass)
thrives in the reservoir. The park's four-season appeal highlights
ecological resilience, with clearer winter views revealing the battle's
harsh conditions. Preservation efforts focus on habitat restoration
through controlled burns and invasive removal, integrated with NPS's
broader Cumberland River watershed initiatives to combat erosion and
pollution.
Fort Donelson offers accessible, interpretive recreation centered on
history and nature, ideal for families and history enthusiasts. The
6-mile (9.7 km) Battlefield Driving Tour features 11 stops with pullouts

trail experience.
Designated to safeguard the forts' archaeological integrity (e.g., unexcavated earthworks yielding bullets and buttons), the battlefield falls under NPS management with the Civil War Sites Advisory Commission, emphasizing cultural landscape preservation. The 2021 Foundation Document outlines goals for resource stewardship, visitor engagement, and partnerships with Stewart County and the Corps of Engineers to mitigate reservoir fluctuations and erosion. Efforts include vegetation management to prevent overgrowth of fortifications and invasive species control, alongside cultural resource inventories (e.g., 2020s geophysical surveys at Fort Heiman). The national cemetery, administered by the Department of Veterans Affairs, ensures perpetual care for its graves. Challenges like urban sprawl and climate impacts (e.g., flooding) are addressed through the NPS's 2025 resilience plan, sustaining the site's role as a "silent witness" to the war's turning point.
