Undercover Reporting

Redpath inaugurated a "Facts of Slavery" column for the New York Tribune, curating slave sale information from the Southern press, and later went South to interview slaves so they could have a forum for relating their experiences in their own words. He later took jobs at Southern newspapers and surreptitiously sent reports back north in the guise of letters to relatives in Minnesota. They, in turn, under prior arrangement, forwarded the reports to editors.
