In five web pages, this synopsis tells the entire story starting in 1803 at Washington City, heading down the Ohio, wintering at St. Louis in 1804, and reaching the Pacific in late 1805. In 1806, they return to St. Louis.
Synopsis Part 1
Washington City to Fort Mandan
by Harry W. Fritz
The Corps of Discovery, as it would be called, or the “corps of volunteers for North Western Discovery,” as Lewis put it, epitomized the rising glory of the United States—its sense of limitless possibilities and unparalleled opportunities.
Synopsis Part 2
Fort Mandan to the Marias River
by Harry W. Fritz
Near the mouth of the Knife, in late October 1804, the expedition settled down for the winter. After the river ice broke up, the keelboat left for St. Louis and six new dugout canoes headed the opposite direction, up the Missouri river.
Synopsis Part 3
The Marias River to the Lemhi Valley
by Harry W. Fritz
The captains were worried. The expedition was quickly running out of time and space: time to cross the Rockies before winter, and space to find the Shoshones, with their horses and guides. Another month of increasingly toilsome river travel would ensue.
Synopsis Part 4
Lemhi Valley to Fort Clatsop
by Harry W. Fritz
After trading for horses with Sacagawea’s people, the expedition turned north and then west, on what would indisputably be the most exhausting and debilitating segment of the entire journey, the passage across the Bitterroot Mountains.
Synopsis Part 5
Fort Clatsop to St. Louis
by Harry W. Fritz
On 23 March 1806, once again battling the rising spring runoff, as it had each of the two previous years on the Missouri, the Corps of Discovery started up the Columbia River towards home.
