The fort covered altogether about four acres and was capable of sheltering a garrison of three hundred men. The expense of its erection was one million dollars, a sum of money only equalled in those days by the expenditure for the fortifications of Louisburg, Quebec, and Crown Point. It is generally believed that large profits went to the commandant and to others interested in its construction. The command of the point in 1760 passed from Macarty to Nenon de Villiers, who led the French and Indians against Washington at Great Meadows in the skirmish which virtually was the opening engagement of the French and Indian War, a part of his force on this occasion being drawn from the garrison of Fort Chartres. The veteran St. Ange de Belle Rive, stationed at Vincennes, took charge of the fort in 1764 and had the melancholy distinction of surrendering it to the English, October 10, 1765, when Captain Thomas Stirling came from Fort Pitt with one hundred Highlanders of the 42d British regiment,--a fitting distinction when one remembers that St. Ange had been in command of the first fort shortly after its establishment, and when there was no rival to French power in all of the West. A predecessor of Fort Chartres in making sure French dominion of the West was Fort St. Louis, on Starved Rock, on the Illinois River, about forty miles southwest of Chicago of to-day and not far distant from the present-day city of Ottawa, Illinois. Of Fort St. Louis there remains not a trace, but to its existence and to La Salle, its intrepid founder, there will for centuries be a natural monument--that great towering crag upon whose flat summit the stronghold was built. A natural phenomenon of great geologic interest, Starved Rock rises directly from a level river plain. Its sides are as steep as castle wall and attain a height of one hundred feet and more. The river washes its western base and its summit overhangs the stream so that water can be drawn therefrom by means of a bucket and a cord. On three sides the pinnacle of the rock is inaccessible and the fourth side might be held by a handful of men against an army. The top of the cliff measures about two hundred feet in diameter and is flat. On this ideal site, in 1682, the French built Fort St. Louis. In less than three months fourteen thousand Indians lay encamped on the plains of the river within sound of the guns of the fort. To-day the point is a pleasure park. From Fort St. Louis many an exploring expedition pushed forth into the wilderness and here many a treaty was concluded with savage tribes. While frequently obliged to give up command temporarily Henry de Tonti, La Salle’s very faithful lieutenant, was supreme at Fort St. Louis practically from its foundation until its abandonment in 1702. In 1718 a number of French traders were making it their headquarters, but its military history ceased with Tonti’s departure.
