Army pioneering expeditions from Fort Leavenworth in the 1820s and 1830s had been undertaken mainly for making treaties with the Great Plains Indians and for protecting trading caravans. Beginning in the early 1840s the prime consideration was to help the American settlers pouring westward. In 1842, 2d Lt. John C. Fremont of the Corps of Topographical Engineers led an expedition to explore and map the Platte River country for the benefit of emigrants moving over the Oregon Trail; his second expedition in 1843 reached Sacramento in Upper California.
