This is from the Intelligencer (Atlanta, Georgia), 19 December 1861, pg.

One remarkable feature about Lincoln's late message is that he avoids
altogether the word "rebel." He has discovered at last that Southern
patriots rejoice to inherit the epithet applied to George Washington--"the
first rebel." He now doses us with the designation of "insurgents." The
coming generation will regard _that_ name equally honorable.
