[105] Dangerous passes on the Mississippi were rendered doubly perilous to early navigators by the presence of bands of robbers. An incident occurred early in 1787, which led to a virtual extermination of these marauders. While ascending the river, Beausoliel, a wealthy merchant of New Orleans, was attacked near Cotton Wood Creek by the Culbert and Magilhay freebooters. After being captured, the merchants made good their escape through the strategy of a negro, killed many of their captors, and returned to New Orleans to report the state of affairs. The following year (1788) the governor issued a proclamation forbidding boats to proceed singly to St. Louis. Accordingly a fleet of ten boats ascended and destroyed the lair at Cotton Wood Creek, the remaining robbers having fled at their approach. This bloodless victory marks the close of the freebooting period. The year was afterwards known in local annals as _L'Annee des dix Bateaux_. See L. U. Reaves, _Saint Louis_ (St. Louis, 1875), pp. 21, 22; and Scharf, _St. Louis_, ii, p. 1092.--ED. [106] In 1805.--FLAGG. _Comment by Ed._ Every house save one was destroyed by fire on June 11, 1805. The memory of the disaster is preserved in the motto of the present seal of the city: _Resurget Cineribus_ (she arises from the ashes). [107] Lieutenant-Colonel Francisco Cruzat, who succeeded (May, 1775) Captain Don Pedro Piernas, the first lieutenant-governor of Upper Louisiana, followed the liberal policy of his predecessor and was highly esteemed by his people. He was followed in 1778 by Captain Fernando de Leyba, who was sadly lacking in tact and political ability; he was displaced for incompetency after the Indian attack of May 26, 1780. Cruzat was reappointed in September and served until November, 1787. One of the first acts of his second administration was to direct Auguste Chouteau to make plans for the fortification of St. Louis; see note 76, _ante_.--ED. [108] One, which occurred during the summer of the present year, was extensively felt. In the vicinity of this fortification, to the south, was an extensive burial-ground; and many of its slumbering tenants, in the grading of streets and excavating of cellars, have been thrown up to the light after a century's sleep.--FLAGG. [109] Colonel John O'Fallon (1791-1865), a nephew of George Rogers Clark, born near Louisville, served his military apprenticeship under General William Henry Harrison during the War of 1812-15. Resigning his position in the army (1818), he removed to St. Louis where he turned his attention to trade and accumulated a large fortune. He endowed the O'Fallon Polytechnic Institution, which was later made the scientific department of St. Louis University, contributed liberally to Washington University, and built a dispensary and medical college. It is estimated that he gave a million dollars for benevolent purposes.--ED.
