On the north bank of the Rock river, 3 M. from its mouth, there was a large summer

village (sometimes called Saukenuk) of the Sauk Indians, built about 1730 and destroyed in 1831; and near the mouth of the Rock river is a bluff called " Black Hawk's watch-tower." A settlement on the island was made in 1816, when the fort was built; the first settlement on the mainland was made in 1826 . In 1841 the town of Rock Island was formed by the consolidation of two small settlements named Stephenson and Farnhamsburg and was incorporated; it received a city charter in 1849 . Upon the west end of the island the United States government in 1816 built Fort Arm-strong, where on the 21st of September 1832, at the close of the Black Hawk War, a treaty of peace was signed by General Winfield Scott and Governor John Reynolds of Illinois and by the chiefs of the Sauk and Foxes, and where, six days before, General Scott and Governor Reynolds had made a treaty with the Winnebagoes . The fort was abandoned in 1836 and was burned in 1855; a monument now marks its site . The Rock Island armoury and arsenal, under an act of 1862, were built in 1863, when a number of captured Confederate soldiers were confined on the island .
