Some of the most noted prisoners were
the women
spies Belle Boyd and Rose O'Neal (aka
Rose
Greenhow).
When the Civil War began, the Old
Capitol in
Washington, was abandoned and
dilapidated. The
government removed
the high board fence surrounding the
building,
replaced the wooden slats nailed over
the windows
with iron bars,
and turned it into a prison. Security
was provided
mainly by guards who constantly paced
around the
outside. Many
prominent prisoners were confined in
the Old
Capitol Prison, including Confederate
generals,
Northern political
prisoners, blockade runners, and spies.
Henry Wirz,
commandant of Andersonville Prison, and
the Lincoln
assassination
conspirators were hanged on the gallows
in the yard
of the Old Capitol Prison.
