Washington Irving's The Adventures of Captain Bonneville Introductory Notice WHILE ENGAGED in writing an account of the grand enterprise of Astoria, it was my practice to seek all kinds of oral information connected with the subject. Nowhere did I pick up more interesting particulars than at the table of Mr. John Jacob Astor; who, being the patriarch of the fur trade in the United States, was accustomed to have at his board various persons of adventurous turn, some of whom had been engaged in his own great undertaking; others, on their own account, had made expeditions to the Rocky Mountains and the waters of the Columbia.

Among these personages, one who peculiarly took my fancy was Captain Bonneville, of the United States army; who, in a rambling kind of enterprise, had strangely ingrafted the trapper and hunter upon the soldier. As his expeditions and adventures will form the leading theme of the following pages, a few biographical particulars concerning him may not be unacceptable.

Captain Bonneville is of French parentage. His father was a worthy old emigrant, who came to this country many years since, and took up his abode in New-York. He is represented as a man not much calculated for the sordid struggle of a money-making world, but possessed of a happy temperament, a festivity of imagination, and a simplicity of heart, that made him proof against its rubs and trials. He was an excellent scholar; well acquainted with Latin and Greek, and fond of the modern classics. His book was his elysium; once immersed in the pages of Voltaire, Corneille, or Racine, or of his favorite English author, Shakespeare, he forgot the world and all its concerns. Often would he be seen in summer weather, seated under one of the trees on the Battery, or the portico of St. Paul's church in Broadway, his bald head uncovered, his hat lying by his side, his eyes riveted to the page of his book, and his whole soul so engaged, as to lose all consciousness of the passing throng or the passing hour.

Captain Bonneville, it will be found, inherited something of his father's bonhommie , and his excitable imagination; though the latter was somewhat disciplined in early years, by mathematical studies. He was educated at our national Military Academy at West Point, where he acquitted himself very creditably; thence, he entered the army, in which he has ever since continued.

The nature of our military service took him to the frontier, where, for a number of years, he was stationed at various posts in the Far West. Here he was brought into frequent intercourse with Indian traders, mountain trappers, and other pioneers of the wilderness; and became so excited by their tales of wild scenes and wild adventures, and their accounts of vast and magnificent regions as yet unexplored, that an expedition to the Rocky Mountains became the ardent desire of his heart, and an enterprise to explore untrodden tracts, the leading object of his ambition.

By degrees he shaped his vague day-dream into a practical reality. Having made himself acquainted with all the requisites for a trading enterprise beyond the mountains, he determined to undertake it. A leave of absence, and a sanction of his expedition, was obtained from the major general in chief, on his offering to combine public utility with his private projects, and to collect statistical information for the War Department concerning the wild countries and wild tribes he might visit in the course of his journeyings.
