How did the underground railroad help slaves run away in 1827?

answer:

The earliest mention of the Underground Railroad came in 1831 when slave Tice Davids escaped from Kentucky into Ohio and his owner blamed an “underground railroad” for helping Davids to freedom.

Most of the slaves helped by the Underground Railroad escaped border states such as Kentucky, Virginia and Maryland.

People known as “conductors” guided the fugitive slaves. Hiding places included private homes, churches and schoolhouses. These were called “stations,” “safe houses,” and “depots.” The people operating them were called “stationmasters.” There were many well-used routes stretching west through Ohio to Indiana and Iowa. Others headed north through Pennsylvania and into New England or through Detroit on their way to Canada.

on the morning of  july 21,  1861, general mcdowell ordered the  unionarmy to attack. it was on this hill that  confederate  colonel thomas jackson and his forces held back theunion  troops.
