When Confederate Brig. Gen. Lloyd Tilghman
was sent to command Fort Donelson on the Cumberland River and hastily
constructed Fort Henry on the east side of the Tennessee River during
the winter of 1861-62, he realized immediately that the fort was indefensible,
being built on low ground that was susceptible to flooding directly
across the river from higher ground. In January 1862 Gen. Albert Sidney
Johnston ordered Tilghman to construct a new fort - known as Fort Heiman
after Col. Aldolphus Heiman of the 10th Tennessee who commanded the
1,100 troops at the fort - on the bluffs on the west bank (Kentucky
side of the river. The new fort remained under construction when Union
Brig. Ulysses S. Grant launched his offensive against Forts Henry and
Donelson in early February 1862.
On February 4-5, 1862, Grant landed his
divisions in two different locations, one on the east bank of the Tennessee
River to prevent the garrison at Fort Henry from escaping or receiving
reinforcements from Fort Donelson and the other to occupy the high ground
on the Kentucky side to ensure the fall of both Forts Heiman and Henry.
After gunboats under the command of Union naval Flag Officer Andrew
H. Foote began bombarding the forts, Tilghman, realizing that Fort Heiman
could not be held, recalled the 1,100 troops building the fort to cross
the river and assist the nearly 2,000 soldiers defending Fort Henry.
The Confederates hoped that the muddy roads would make it impossible
for the Union army to set up artillery on the partially completed Fort
Heiman. On February 6, Tilghman surrendered Fort Henry after 70 minutes
of bombardment, because it was surrounded by rising water and could
not be supported by infantry. Tilghman decided to withdraw all troops
from Fort Henry to Fort Donelson with the exception of one battery which
he left behind to delay the Union assault and secure his retreat. After
the capture of both Fort Henry and the uncompleted Fort Heiman, the
latter was occupied by troops under Brig. Gen. Lew Wallace on February
6. Thus, the surrender of Forts Heiman and Henry enabled the Federals'
wooden gunboats to ascend the Tennessee River south to Muscle Shoals,
Alabama, and set the stage for Grant's successful assault against Fort
Donelson 11 miles to the east on the Cumberland River on February 16.
Western Kentucky and Tennessee continued
to play a vital role in military operations during the remainder of
the Civil War. For the Union, the Tennessee and Cumberland rivers were
a vital supply line that had to be maintained. For the Confederates,
the area between the rivers was a sparsely defended region which cavalry
raids and guerilla operations could penetrate easily to disrupt Union
communication and supply lines. Thus, Federal troops occupied unfinished
Fort Heiman until March 6, 1863, to afford Union protection to the people
in the area and, perhaps more importantly to the Union army, protect
the vital supply lines that the Tennessee and Cumberalnd rivers had
become.
During 1862-63, Fort Heiman was garrisioned
by troops from the 5th Iowa Cavalry under the command of Col. W. W.
Lowe. Forts Heiman, Henry, and Donelson offered a haven for a growing
number of refugees, most of whom were slaves seeking safety within the
Union lines. The Federals housed the freedmen, who were officially termed
"contraband of war," employing them as laborers at the forts
and in the area's industries. At least two African-Americans are known
to have been employed at Fort Heiman.
Before evacuating the fort on March 6,
1863, as part of a general buildup of Union forces in the region, Lt.
Col. M. T. Patrick, in command of the post at Fort Heiman, was ordered
to level the river face of the fort's earthworks. Patrick reported that
the earthworks fronting the river were "very slight - the fort
never having been completed by the rebels." Although the earthwork
fortifications along the river were destroyed, largely intact outer
earthworks of the fort along the crest of the bluffs, an upper battery
or redoubt, and remnants of what may have been a powder magazine remain
on site.
Despite its strategic location, neither
side made a sustained effort to occupy Fort Heiman once the war moved
south into Tennessee. Perhaps, the greatest Confederate military success
in the Fort Heiman vicinity occurred in late October 1864 when Confederate
Brig. Gen. Nathan Forrest occupied the fort with 3,500 men. On October
28, using the fort as their base, Forrest's cavalrymen fired upon and
sank the Union steamboat Mazeppa. Two days later, the Confederates
continued their assault on Union vessels passing along the Tennessee
River from Fort Heiman, firing on the Anna, disabling the Undine,
forcing the Venus to surrender, and causing the J. W. Cheeseman
to be abandoned. Thereafter, the Confederates took a Union vessel and
headed up river where they engaged the Union navy. Eventually Forrest
burned all the seized ships once they had been stripped of their cargoes
of food and supplies. During these encouters only one Confederate was
wounded, while 8 Union troops were killed, 11 wounded, and 43 captured,
including one officer.
On November 4, Forrest launched his most
successful raid during the Civil War from his base at Fort Heiman, attacking
the Union supply base at Johnsonville, Tennessee, some 30 miles to the
south at the western terminus of the Nashville and Northwestern Railroad.
During the raid, Forrest's cavalrymen destroyed 4 Union gunboats, 14
transports, 20 barges, and 26 pieces of artillery, captured 150 Union
soldiers, and burned millions of dollars' worth of stockpiled supplies
bound for Nashville and Union Maj. Gen. George H. Thomas' army. During
this encounter, Confederate losses were two killed and nine wounded.
