The La Salle Expedition on the Mississippi River: A Lost Manuscript of Nicolas de La Salle

The La Salle Expedition on the Mississippi River presents the definitive English translation of Nicolas de La Salle’s diary account of René-Robert Cavelier, Sieur de La Salle’s 1682 discovery expedition of the Mississippi River from Canada to the Gulf of Mexico. This previously unknown manuscript copy was discovered recently in the collection of rare books in the Texas State Archives.

It provides the most complete and authoritative account available of this historic North American adventure and territorial claim. By careful cross- document analysis, Foster projects an extended expedition chronology that adds about two weeks to the journey, corrects the date that La Salle’s claim was announced, and revises erroneous interpretations made by most contemporary French and American scholars. The work includes maps prepared by the noted Southwest cartographer John V. Cotter.
