The only think that happened between DC and Camp Dubois is Lewis traveled back and forth (by himself by horseback) from Philadelphia, Pennsylvania several times to purchase the supplies (boats and food stuff) for the LC Expedition. Only reason Lewis was in DC was that he was Pres Jefferson private secretary. Lewis also traveled back and forth several times from DC to Harpers Ferry to order/purchase rifles and some tools and ammunition (gun power and mini-balls) and attend Dr Rush's first aid training. He eventually picked up the killboat (the big one) and with 5 troopers, traveled from Philadelphia to the Ohio River to the Mississippi river then up to Camp Dubois for the winter. That trip from DC to Philad. & harpers ferry & eventually to St Louis (Camp Dubois) trip was not considered part of the Lewis and Clark Expedition. Did not notice where you live but the best place to start the L & C Expedition is at Charlottesville at Monticello (Thomas Jefferson's plantation). Monticello is where the real planning of the expedtion started. The brain childs behind the year long planning for the Expedition were Jefferson and Lewis (mostly lewis)...was actually ingenious what Lewis took along....were overstocked with gun power and writing paper. The expedition trip started in Illinois, (near Akton(sp?), Ill) at Camp Dubois on the Wood River. Great museum there at approximate site of Camp Dubois. Trip Ended at Astoria along the Pacific. But they went one route but returned over 3 differrent routes and 3 separate groups. The facinating part of the expedition is 6 troops (including Lewis and Clark) (all those that could read and write) kept quite good diaries most days (journals) and most of these have been preserved. They all met up at in North Dakota at "Reunion Bay" (today a cattle ranch) on the Missouri River. Take a duel sport to get there. If you live close to DC the National History Museum has one of the few artifacts still in existance, Lewis's pocket compass.
