Thomas P. Slaughter interrogates the explorers' dreams, how they wrote and what they aimed to possess, their interactions with animals, Indians, and each other, their sense of themselves as leaders and men, and why they feared that they had failed their nation and President. Slaughter's Lewis and Clark are more confused, frightened, courageous, and flawed than in previous accounts. They are more human, their expedition more dramatic, and thus their story is more revealing about our own relationships to history and myth.
