While researching connections between Maryland and the Lewis and Clark story, Lorna Hainesworth turned up a June 6, 1803 letter from Meriwether Lewis to William Linnard, the Army’s military agent in Philadelphia — a document missing from Donald Jackson’s standard Letters of the Lewis and Clark Expedition and overlooked by Ambrose, Cutright, and Dillon. The letter lays out, in exacting detail, how Lewis wanted his accumulated stores moved from Philadelphia and Harpers Ferry to Pittsburgh: the team and driver to hire, the route to follow, the schedule, the careful handling of his box of mathematical instruments, and how the expenses were to be accounted.
Read alongside four related 1803 letters (including the “Portable Soup” letter to General William Irvine), it reconstructs Lewis’s spring-to-summer travels and introduces the cadre of quartermasters, purveyors, and armory officers — Israel Whelan, Thomas Cushing, Joseph Perkins, George Ingels, and Irvine — who outfitted the expedition. The find reveals Lewis at his logistical best: not only an explorer, but a meticulous quartermaster and project manager.
