Watch and Wait by Oliver Optic

Dandy, lacerated and bleeding, but still insensible, was conveyed to his chamber in the mansion house, by some of the servants. His physician was an old slave, skilled in the treatment of cases of this kind. When the patient recovered from the swoon into which he had fallen, his back was carefully washed, and the usual remedies were applied. Though suffering terribly from the effects of his wounds, he did not permit a sigh nor a groan to escape him.

The mangled flesh could be healed, but there was no balm at Redlawn that could restore his mangled spirit. Dandy felt that he had been crushed to earth. Slavery, which had before been endurable with patience and submission, was now intolerable. He had been scourged with the lash. He had realized what it was to be a slave in the most bitter and terrible sense.
