Charles Ledyard Norton, Appletons' Cyclopædia of American Biography (1900)
“ Any one of the present generation who is reasonably fair-minded must see that it is the work of a judicial mind, which seeks to do exact justice, irrespective of patriotic considerations. It was its fate, however, to stir up controversies as harsh and enduring as any of those in which its author was previously engaged, and it was freely denounced on both sides of the ocean as grossly unfair for diametrically opposite reasons. Cooper's facts have borne the test of time, and the work must always remain an authority on the subject treated. ”
