Gass's Journal of the Lewis and Clark Expedition

Patrick Gass joined the Lewis and Clark expedition as a private in the army, but after the death of another member due to appendicitis, he was quickly promoted to sergeant. By the end, he was given command of the party when Lewis and Clark were both away on separate explorations. His skills as a carpenter were valuable for the expedition, and he proved himself to be an honorable soldier throughout. Although he lived to be nearly 100, this journal only covers the time spent on the expedition.
