[76] In 1764 Auguste Chouteau made tentative plans for the fortification of St. Louis. In obedience to an order by Don Francisco Cruzat, the lieutenant-governor, he made a survey in 1781 for the purpose of perfecting these earlier plans. In the same year the stockade was begun immediately south of the present site of the courthouse. In 1797 the round stone tower which Flagg mentions was constructed and preparations made for building four additional towers; the latter were never completed. From 1804 to 1806 these fortifications were used by the United States troops, and then abandoned for military purposes. The commandant's house served as a courthouse from 1806 to 1816; and the tower as a jail until 1819. For a detailed description of the plans, see J. F. Scharf, _St. Louis City and County_ (Philadelphia, 1883), p. 136 ff.--ED. [77] For a brief sketch of William H. Ashley see Maximilian's _Travels_, in our volume xxii, p. 250, note 198. He purchased (1826 or 1827) eight acres on the present site of Broadway, between Biddle and Bates streets, St. Louis, where he built a handsome residence. Bloody Island, now the Third Ward of East St. Louis, was formed about 1800 by the current cutting its way through the neck in a bend of the river. For a long time it was not determined to what state it belonged, and being considered neutral ground many duels were fought there, notably those between Thomas H. Benton and Charles Lucas (1817), United States District Attorney Thomas Rector and Joshua Barton (1823), and Thomas Biddle and Spencer Pettis (1830). The name was derived from these bloody associations.--ED. [78] For a sketch of Charlevoix, see Nuttall's _Journal_, in our volume xiii, p. 116, note 81.--ED. [79] D'Ulloa, the first Spanish governor of Louisiana, sent a detachment of soldiers to St. Louis in 1767. Later, these troops were transferred to the south bank of the Missouri, a few miles above its mouth, where "Old Fort St. Charles the Prince" was erected. General Wilkinson built Fort Bellefontaine on this site in 1805. From 1809 to 1815 this was the headquarters of the military department of Louisiana (including Forts Madison, Massac, Osage, and Vincennes). It was the starting point of the Pike, Long, and Atkinson expeditions. On July 10, 1826, it was abandoned for Jefferson Barracks, but a small arsenal of deposits was maintained here until 1834. The land was eventually sold by the government (1836). See Walter B. Douglas's note in Thwaites, _Original Journals of the Lewis and Clark Expedition_ (New York, 1905), v, pp. 392, 393.--ED. [80] North of Missouri River, twenty miles above its confluence with the Mississippi, where the bluffs of the two streams unite, two smooth, treeless, grass-covered mounds stand out from the main bluffs. These mounds, a hundred and fifty feet in height, were called by the early French "mamelles" from their fancied resemblance to the human breast.--ED.
