Does anyone have an example of a primary source that talks about about Harriet Tubman or those that encountered her?? Including some quote or something the source said about her impact.

(A primary source is any source, document or artifact that was created at the time of the event. It was usually created by someone who witnessed the event, lived during or even shortly afterwards, or somehow would have first-hand knowledge of that event. A secondary source, by contrast, is written by a historian or someone writing about the event after it happened. )
