Operations Security for Harriet
Tubman and the Underground depend-
ed greatly on secrecy and obscurity.
This operation was so successful that
Tubman was never caught and the
Underground Railroad system was
never compromised; this is one of the
greatest feats ever coordinated by
people from all walks of life.

Proud Statement to Frederick Douglas
by Harriet Tubman :
“I was conductor of the Underground
Railroad for eight years, and I can say
what most conductors can’t say – I
never ran my train off the track and I
never lost a passenger.”
- Harriet Tubman
