内容简介：
It was the early springtime, and my history tells me the year was 1832, although now that seems so far away I almost hesitate to write the date. It appears surprising that through the haze of all those intervening years-intensely active years with me-I should now be able to recall so clearly the scene of that far-off morning of my youth, and depict in memory each minor detail. Yet, as you read on, and realize yourself the stirring events resulting from that idle moment, you may be able to comprehend the deep impression left upon my mind, which no cycle of time could ever erase. I was barely twenty then, a strong, almost headstrong boy, and the far wilderness was still very new to me, although for two years past I had held army commission and been assigned to duty in frontier forts. Yet never previously had I been stationed at quite so isolated an outpost of civilization as was this combination of rock and log defense erected at the southern extremity of Rock Island, fairly marooned amid the sweep of the great river, with Indian-haunted land stretching for leagues on every side.
