President Roosevelt, an ardent conservationist, was caught between the two.

Men and women, black and white, risked their lives to carve an elaborate network of escape routes out of slavery in the mid 1800s -- trails and backroads, safehouses, river crossings and night trains leading as far north as Canada.

But flight to free territory didn't guarantee freedom; fugitives could be hunted down and returned.
