The great Republic formed after seven years of valor and sacrifice from thirteen weak and scattered colonies, had, through several decades of unprecedented development and prosperity, become a most powerful homogeneous nation. In its creation and progress, there was left one element of discord; one vexed question remained unsettled that threatened to dismember the government, destroy the federation and seriously embarrass our advance toward a higher civilization. When reason became dethroned, logic and argument failed, the problem had to be settled by the dread arbitrament of war. The young men, the very flower of our national manhood, were required to decide that great problem. For the very important duties of citizenship and soldier, the distinguished author of this volume was well equipped for the important duties of that time and to render important service for his government and the people of our country. Descending from the best of ancestral stock, born and reared in what was known as the Great Middle West, in an atmosphere of national independence, a region of our country where we find the highest type of our American civilization, he grew to manhood under the most favored auspices. Educated at excellent schools and institutions of learning, his mind became well stored with useful knowledge concerning his own country and the world. He then went to that famous military academy, West Point, where he acquired a thorough military training and those manly attributes for which the institution is noted. His mind naturally sought wider fields of usefulness, and when he resigned, he became identified with that marvelous civil development that has transformed a vast wilderness and mountain waste into productive communities and States. As a civil engineer, he was most useful and successful. When the great crisis came, he was found true and steadfast in his allegiance to the national welfare amid chaos, doubt and uncertainty. His loyalty was invaluable, his patriotism sublime; among the first to volunteer, his record was most commendable and praiseworthy, ever present in every campaign and battle in which his company or regiment was engaged. Four times breveted for distinguished conduct in battle, he fought for a principle, and had the satisfaction of witnessing its final triumph, and its universal approval by the civilized world. In that "war for civilization" on our western frontier, he again rendered distinguished service, not only by his conspicuous gallantry in action against Indians, but by his skill and genius as a commander in achieving success and victory where there was little prospect of winning either. In a campaign where success depends entirely upon the ability of the commander, there he succeeded.
