My arm is paralyzed; my voice that once could be heard all along the line, is gone; I can scarcely speak above a whisper; my hearing is very much impaired, and sometimes I feel as if I wished the end would come; but I have some misrepresentations of my battles that I wish to correct, so as to have my record correct before I die.
