CAMP CAMERON, March 13th, 1877.
Morning clear, still and pleasant. The guard, George Tracy, informs me that Col. Nelson and Judge Howard have gone. Since my confinement here, I have reflected much over my sentence, and as the time of my execution is drawing near, I feel composed, and as calm as the summer morning. I hope to meet my fate with manly courage. I declare my innocence. I have done nothing designedly wrong in that unfortunate and lament-able affair with which I have been implicated. I used my utmost endeavors to save them from their sad fate. I freely would have given worlds, were they at my command, to have averted that evil. I wept and mourned over them before and after, but words will not help them, now it is done. My blood cannot help them, neither can it make that atonement required.
