Originally published by the Combat Studies Institute in 2004 this study raises a variety of teaching points that are relevant to today’s officer. In addition, the expedition exemplifies the values that have guided the American soldier to the present day. The Staff Ride Handbook for the Lewis and Clark Expedition provides a systematic approach to the analysis of this key operation. Part I consists of an expedition overview that establishes the context for the individual actions to be studied in the field. Part II surveys the Army during the early 19th century, detailing the organization, weapons, transportation, logistic support and medical support for the Corps of Discovery. Part III consists of a suggested itinerary of sites to visit to obtain a concrete view of the expedition in its several phases. For each site, or stand, there is a set of travel directions, a discussion of the action that occurred there, and vignettes by participants in the expedition that further explain the action and which also allow the student to sense the human drama of the journey into the unknown. Parts IV and V provide information on conducting a staff ride along the Lewis and Clark route, the integration phase, and logistics considerations. Appendix A provides biographical sketches of key expedition members. Appendix B provides a copy of the ‘Detachment Orders’ written by the officers and NCOs of the corps. Appendix C overviews the uniforms worn by the expedition members, and Appendix D provides copies of the visuals used at the instructional stands. An annotated bibliography suggests sources for further study.
