John Catron,
Missouri v. Iowa (48 U.S. 660)…
“ The war of 1812 seems to have hindered a survey of the lines, as, in 1815, by another treaty, peace was reestablished between the contracting parties, and former treaties were renewed, and in 1816 John C. Sullivan was sent by the United States to run the lines north of the Missouri River. The Osages, by the treaty of 1808, having surrendered all claim to territory north of the Missouri River, it became necessary that they should show to the United States what part of that country they owned, so that it might be separated, by a defined boundary, from other Indian territories. ”
