While Confederate
artillery batteries erected below Washington, D.C. had more bark than
bite – observers wrote of poor marksmanship and munitions -- they effectively blockaded
the vital Potomac River for five months.
Among the
most imposing was Cockpit Point Battery in Prince William County, Va. Sitting
atop a 70-foot bluff, the fort had an air of mystery from the beginning.
It was built in secret, with trees left in front to better hide the construction.
Curious Federal troops on the Maryland side of the river eventually used a balloon
to try to figure out how many men were at Cockpit Point and other batteries in
the area.
The Rebel emplacements thrown up early in the war saw relatively little action, but the threat embarrassed
the Federal government and to a degree stymied efforts to resupply the capital.
“It is
something that is really unknown, even to hard-core Civil War buffs,” said Bill
Backus of the county’s Historic Preservation Division.

Backus and
colleague Rob Orrison earlier this month conducted the first public tours (above) of
the property, which was donated about a year ago by the developers of Potomac Shores,
a large residential and golf community just to the north of Cockpit Point.
Cockpit Point Civil War Park, a few miles east of Dumfries, is not technically open. The 113 acres are split by a busy railroad line that passes by a chemical facility and the Possum Point Power station, modern facilities that bookend the park.
County
officials for now will concentrate on a 93-acre parcel of the property, with
the hopes of putting in a small parking lot later this year (until then, people
are not encouraged to drive to the site). That side will highlight natural
resources, including a pond. The park has two bald eagle nests.
“We think it
is going to be mixed use, because access of the earthworks is limited, because
of the railroad,” Backus said. “Our ultimate goal is to put a trail system to
both sides of the park.”
There is no
timetable for putting a trail or interpretive markers on the battery side of
the property. There currently is no safe (or legal) way to cross
the railroad. Officials encourage visitation through special tours in the
spring and November.

The 20 people
who took part in this month’s visit saw “some of the few batteries that remain
from the blockade of the Potomac River in the first year of the war,” said
Backus.
In a press
release announcing the tours, Orrison, the county's
historic site operations supervisor, wrote: "This property is
unique as it contains some of the best preserved earthworks and forts from the
Civil War in Northern Virginia. It's by far the best-preserved Civil War
battery associated with the Potomac Blockade."
'A remarkable military position'
The Texas
Brigade is said to have been among the units that Brig. Gen. Isaac Trimble
employed in autumn 1861 to build the four lunettes on the bluff, called Possum
Nose.
Backus said
the batteries probably are about 150-200 yards from the Potomac.

The
Confederacy rotated artillery in and out of the fort. Sometimes there were six,
sometimes fewer. A 30-pounder Parrott, nicknamed “Long Tom,” was used, along
with guns from the Norfolk naval station. Between 100 and 200 men were in the garrison.
The Federal
government was worried by Cockpit Point and nearby Shipping Point, Freestone
Point and Evansport fortifications (totaling 37 heavy guns); a pro-Unionist called the former a “remarkable military
position.”
Backus and Orrison recently wrote about the blockade for Blue & Gray magazine. They stress
the Federal government needed an open Potomac River for resupply and
communication reasons, along with a wish to keep Maryland out of the fight.
Orrison, in the blog Emerging Civil War, wrote: “Though the batteries were constructed under the auspices
of the Confederate Navy, the men manning the guns were infantry. Various units
moved in and out of the area to man the guns, and their skill as gunners was
obvious, as they rarely were able to hit anything that fired along the river.”
While the blockade lasted until March 1862, Cockpit Point took a beating
from the Union navy in January 1862. Two vessels – the USS Yankee and USS
Anacostia -- pounded the batteries from
positions that couldn’t be easily hit by return fire. Shots from the USS
Anacostia were accurate enough to force the Confederates to abandon one of the
batteries. But the fort remained in Southern hands

Federal
troops and batteries on the Maryland side hoped for help from Maj. Gen. George
B. McClellan, who could have used his massive force on the Virginia side to
attack the batteries from the rear. But he apparently felt that did not fit
within the larger strategy, Orrison writes.
Instead, it
was Rebels who took the batteries out of action.
In early
March 1862, they withdrew to build new defenses along the south bank of the
Rappahannock River. An attempt was made to destroy the river positions.
For their
part, Federal forces used Cockpit Point to launch patrols, “mainly looking for
guerrillas.” They knocked the batteries down further so they would be of little or no
use if the Confederates retook them.

Keeping further deterioration in check
Backus says
the remnants of the lunettes are quite discernible. Trees have moved in
and other natural forces have worked on the fortifications over the past 155 years. Still, the state of preservation is considered to be good and there have been few modern disturbances.
Foundations
of winter huts are still in place, along with the remains of a communications
trench.
A study conducted for the county said it should work to maintain surrounding forest to
protect surviving earthworks and take steps to prevent vandalism.
There has
been evidence of fairly recent relic hunting, and officials don’t want visitors
on site. They could cause more damage to the batteries. “We are trying to keep
it protected by not marking where everything is,” Backus told the Picket.
There’s no
interest in reconstructing the defenses. Instead, officials want to prevent any
further deterioration. One bluff is eroding and officials may step in to help
stabilize it.
