The command arrived at Mendota August 24 and was at once put to building the log houses of a cantonment. The site was near the present ferry and the hamlet of Mendota, where a sharp eye may still note traces of foundations. In September a reinforcement of one hundred and twenty arrived. In the spring of 1820 the companies were put into camp above the fort, near the great spring known to all early settlers. It was named Camp Coldwater. In July the command passed to Colonel Joseph Snelling, who held it till near the time of his death in 1828. A daughter born in his family a short time after their arrival was the first white child born in Minnesota.
Colonel Snelling at once began the erection of a fort, which, however, was not ready for occupation till October, 1822. It was a wooden construction, for which the logs were cut on the Rum River. In 1821 a rude sawmill was built at “the Falls” which converted the logs into lumber. This was of course the first sawmill in Minnesota. Two years later a “run of buhrs” was put in, and a first flour mill established. Colonel Snelling named his work “Fort Saint Anthony,” but in 1824, upon recommendation of Major-General Winfield Scott, after a visit to the place, that name was changed to “Fort Snelling,” in recognition of the enterprise and efficiency of its builder.
The reader must not be allowed to fear that the government was trespassing on Indian ground when building Fort Snelling. Pike had bargained for the site in 1805, but the government for fourteen years neither took possession nor tendered payment. The Senate on ratifying the treaty filled the blank in article II by inserting $2000, and Congress in 1819 made an appropriation of that amount. In anticipation of the dispatch of a detachment of troops, Major Forsyth was ordered to transport $2000 worth of goods to the Sioux country and deliver them in payment for the lands ceded to Pike. It chanced that his boats arrived at Prairie du Chien in time to make the further ascent of the river in company with the command of Colonel Leavenworth. The payment was happily managed. On his way up river Major Forsyth called at the villages of Wabashaw, Red Wing, and Little Crow, and gave each of those chiefs a present of blankets, tobacco, powder, or other goods. On arrival at destination similar presents were made to five other chiefs, whose villages were not distant. In each case the major records that he had to give a little whiskey. The United States could afford such generosity.
