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. A mere handful of troops was quartered there, technically two companies of infantry, yet numbering barely enough for one; and this in spite of rumors daily drifting to us that the Sacs and Foxes, with their main village just below, were already becoming restless and warlike, inflamed by the slow approach of white settlers into the valley of the Rock. Indeed, so short was the garrison of officers, that the harassed commander had ventured to retain me for field service, in spite of the fact that I was detailed to staff duty, had borne dispatches up the Mississippi from General Gaines, and expected to return again by the first boat. The morning was one of deep-blue sky and bright sunshine, the soft spring air vocal with the song of birds. As soon as early drill ended I had left the fort-enclosure, and sought a lonely perch on the great rock above the mouth of the cave. It was a spot I loved. Below, extended a magnificent vista of the river, fully a mile wide from shore to shore, spreading out in a sheet of glittering silver, unbroken in its vast sweep toward the sea except for a few small, willow-studded islands a mile or two away, with here and there the black dot of an Indian canoe gliding across the surface. I had been told of a fight amid those islands in 1814, a desperate savage battle off the mouth of the Rock, and the memory of this was in my mind as my eyes searched those distant shores, silent now in their drapery of fresh green foliage, yet appearing strangely desolate and forlorn, as they merged into the gray tint of distance. Well I realized that they only served to screen savage activity beyond, a covert amid which lurked danger and death; for over there, in the near shadow of the Rock Valley, was where Black Hawk, dissatisfied, revengeful, dwelt with his British band, gathering swiftly about him the younger, fighting warriors of every tribe his influence could reach. He had been at the fort but two days before, a tall, straight, taciturn Indian; no chief by birth, yet a born leader of men, defiant in speech, and insolent of demeanor in spite of the presence also at the council of his people's true representative, the silent, cautious Keokuk.
