Book excerpt: This book tells the story of some people who went west in 1846. 1846 saw the outbreak of the war with Mexico, Fremont and the Bear Flag Revolt, a great Oregon and California emigration, the conquest of New Mexico, Doniphan's expedition, and the tragedy of the Donner party of emigrants--half adults, half childrens. These narratives are told as stories in themselves, as related parts of the great national spectacle, and as the culmination of the whole movement of American westward migration from the Atlantic to the Pacific.
