how did enslaved people escape to the north? on the underground railroad through military force getting jobs in factories by taking part in insurrections

Explanation:

The Underground Railroad was a network of secret routes and safe - houses that helped enslaved African Americans escape to free states and Canada. Military force was not a common way for individual enslaved people to escape. Getting jobs in factories was not a means of escape. Insurrections were uprisings, not a typical escape method.
