Abandonment of the rendezvous system after 1840 increased the importance of fixed trading posts. The deterioration of Fort William prompted the American Fur Co. to replace it in 1841 with a more pretentious adobe-walled post which cost some $10,000. Christened Fort John, presumably after John Sarpy, a stockholder, the new fort, like its predecessor, was popularly known as “Fort Laramie.” Competition in the declining fur trade led to open traffic in “fire-water,” and the debauchery of the Indians around Forts Platte and Laramie was noted by many travelers of the early 1840’s. Rufus B. Sage vividly describes the carousals of one band of Indians which ended with the death and burial of a Brule chief. In a state of drunkenness, this unfortunate merrymaker fell from his horse and broke his neck while racing from Fort Laramie to Fort Platte. Trade goods for the rival posts came out in wagons over the Platte Valley road from St. Joseph or over the trail from Fort Pierre on the upper Missouri. On the return trip, packs of buffalo robes and furs were sent down to St. Louis. In addition to wagon transportation, cargoes were sent by boat down the fickle Platte, which often dried up and left the boatmen stranded on sandbars in the middle of Nebraska. _The First Emigrants_ Up to 1840, traders, adventurers, and missionaries dominated the scene. The first party of true covered-wagon emigrants, whose experiences were recorded by John Bidwell and Joseph Williams, paused at Fort Laramie in 1841. The following year Lt. John C. Fremont visited the fort on his first exploring trip to the Rocky Mountains. Recognizing its strategic location and foreseeing the covered-wagon migrations, Fremont added his voice to those recommending the establishment of a military post at the site. In 1843, the “cow column,” first of the great migrations to Oregon, reached the fort under the guidance of Marcus Whitman. This group numbered nearly 1,000 persons. Thereafter, the emigrants with their covered wagons became a familiar sight each May and June. Impressions of the swift-flowing Laramie River, the white-walled fort, the populous Indian tepee villages, the “squawmen” at the fort, and the dances held on level ground beneath nearby cottonwoods were frequently recorded by diarists. More than 3,000 Oregon-bound emigrants paused at the fort in 1845, intermingling peacefully with the numerous Sioux Indians encamped there. Later that summer, peace still prevailed when Col. Stephen Watts Kearny arrived with five companies of the First Dragoons, encamped on the grassy Laramie River bottoms, and held a formal council with the Indians between the two forts. Here the Indians were warned against drinking “Taos Lightning” or disturbing the emigrants and were assured of the love and solicitude of the Great White Father. They were also duly impressed with his power as symbolized in a display of howitzer fire and rockets.
