There is little doubt that this post was held continuously by the French as a military post until 1696, when the French authorities at Quebec withdrew all their troops from Wisconsin, and as a trader's post or settlement, until the surrender in 1763 to the British of all French claims east of the Mississippi. It was probably garrisoned near the close of the latter period. It remained in the possession of the French some time, as the English, thinking it impossible to compete for the commerce of the Indian tribes with the French traders who had intermarried with them, and so acquired great influence, did not take actual possession until many years later. The post is occasionally mentioned by the early voyageurs, and the prairie which it commanded was known as the "Prairie du Chien," or praire of the dog, as early as 1763, and is so mentioned by Carver. It was not formally taken possession of by the United States until 1814, when Gov. Clarke with two hundred men came up from St. Louis to Prairie du Chien, then under English rule, to build a fort and protect American interests at the village. At that time there were about fifty families, descended chiefly from the old French settlers. These were engaged chiefly in farming, owning a common field four miles long by a half mile wide. They had outside of this three separate farms and twelve horse mills to manufacture their produce. The fort, held by a few British troops under Capt. Deace, surrendered without resistance, but soon after the British traders at Mackinaw sent an expedition under Joe Rolette, Sr., to recapture the post, which they did after a siege of three days, the defenders being allowed to withdraw with their private property on parole. They were followed by the Indians as far as Rock Island. Meanwhile, Lieut. Campbell, with reinforcements on his way from St. Louis, was attacked, part were captured and the remainder of his troops driven back to St. Louis. Late in 1814 Maj. Zachary Taylor proceeded with gunboats to chastize the Indians for their attack on Campbell, but was himself met and driven back. The following year, on the declaration of peace between Great Britain and America, the post at Prairie du Chien was evacuated. The garrison fired the fort as they withdrew from it.
