Troops, sometimes mounted and sometimes afoot, left the post daily for what I assumed to be patrol duty. I judged the little force of a thousand men were detailed here to maintain the authority of a distant government in a conquered country. Later, I learned that my surmise was correct, and this was but one of a great chain of similar posts that dotted the new frontier of the black nation into whose hands I had fallen. Slowly I learned their tongue, so that I could understand what was said before me, and make myself understood. I had seen from the first that I was being treated as a slave—that all whites that fell into the hands of the blacks were thus treated. Almost daily new prisoners were brought in, and about three weeks after I was brought in to the post a troop of cavalry came from the south to relieve one of the troops stationed there. There was great jubilation in the encampment after the arrival of the newcomers, old friendships were renewed and new ones made. But the happiest men were those of the troop that was to be relieved. The next morning they started away, and as they were forced upon the parade ground we prisoners were marched from our quarters and lined up before them. A couple of long chains were brought, with rings in the links every few feet. At first I could not guess the purpose of these chains. But I was soon to learn. A couple of soldiers snapped the first ring around the neck of a powerful white slave, and one by one the rest of us were herded to our places, and the work of shackling us neck to neck commenced. The colonel stood watching the procedure. Presently his eyes fell upon me, and he spoke to a young officer at his side. The latter stepped toward me and motioned me to follow him. I did so, and was led back to the colonel. By this time I could understand a few words of their strange language, and when the colonel asked me if I would prefer to remain at the post as his body servant, I signified my willingness as emphatically as possible, for I had seen enough of the brutality of the common soldiers toward their white slaves to have no desire to start out upon a march of unknown length, chained by the neck, and driven on by the great whips that a score of the soldiers carried to accelerate the speed of their charges. About three hundred prisoners who had been housed in six prisons at the post marched out of the gates that morning, toward what fate and what future I could not guess. Neither had the poor devils themselves more than the most vague conception of what lay in store for them, except that they were going elsewhere to continue in the slavery that they had known since their capture by their black conquerors—a slavery that was to continue until death released them.
