The Oregon Trail by Francis Parkman Chapter 12 — "Ill Luck" In Chapter 12, Parkman hits a stretch of pure frontier misfortune. Everything that can go wrong does go wrong. The chapter opens with a string of setbacks—sick horses, broken gear, and the kind of bad weather that turns the prairie into a test of endurance. Parkman and his companions find themselves slowed, frustrated, and worn down by the grind of daily travel. But the "ill luck" isn't just physical. Parkman's own health begins to falter, and he describes the creeping exhaustion and fever that make every mile feel heavier. The chapter captures the reality of the trail in a way few writers ever have: the West wasn't just grand vistas and adventure—it was hardship, monotony, and the constant threat of things falling apart.

Despite the setbacks, Parkman's eye for detail never dims. He paints the landscape with the same care as always, showing how beauty and misery often walked hand‑in‑hand on the frontier. By the end of the chapter, the party is still moving forward, but the trail has taken its toll.
