In 1861, the United States was a nation divided.
There were White people who depended on enslaving Black people to support their economy and their lifestyle. And White people who thought enslavement was wrong and wanted to abolish it. Most of the former were in the South. But New York had its share of people who supported them.
Then came the Civil War. No battles were fought in New York State. But that didn’t mean its citizens weren’t involved.
And long before that war, there came a railroad that wasn’t really a railroad at all.
