Abandonment of the rendezvous system after 1840 increased the importance of fixed trading posts. The deterioration of Fort William as well as competition from a rival post (Fort Platte) constructed on the North Platte River caused the American Fur Co. to replace Fort Laramie 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, continued to be popularly known as "Fort Laramie." The rival post, known as Fort Platte was constructed in late in 1840 or early in 1841 by Lancaster P. Lupton, a veteran of the fur trade in what is now Colorado, but later operated by at least two other independent trading companies.
Competition in the declining fur trade led to open trafficking in alcohol and the debauchery of the Indians around Fort Platte and Fort Laramie and was noted by many travelers of the early 1840's. Rufus B. Sage (Reference) 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 both of 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 River. 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 what would be Nebraska.
Up to 1840, trappers and traders, dominated the scene however adventurers, travelers, missionaries and even tourists passed through the fort, while accompanying the annual supply trains to rendezvous. The first party of true covered-wagon emigrants, whose experiences were recorded by John Bidwell and Joseph Williams, paused at Fort Laramie in 1841 and after that year increasing numbers of immigrants would pass the fort. In 1841, Lt. John C. Fremont visited the fort on his first expedition to the Rocky Mountains. Recognizing its strategic location along what would become the Oregon Trail and foreseeing the covered-wagon migrations, Fremont added his voice to those recommending the establishment of a military post at the site.
While Fort Platte was abandoned in 1845 due to declining profits in the fur trade, trade continued to be brisk at Fort Laramie during the winter of 1845-46, and it is recorded that during the following spring a small fleet of Mackinaw boats, under the leadership of the veteran factor P. D. Papin, successfully navigated the Platte with 1,100 packs of buffalo robes, 110 packs of beaver, and 3 packs of bear and wolf skins. However, despite a moderately brisk business with the emigrants, trading at Fort Laramie continued to suffer from the general decline of the fur markets and in competition with independent dealers in Mexican whiskey.
For some years the Government had considered establishing military posts along the Oregon Trail for the protection of emigrants, and this site at confluence of the Laramie and North Platte Rivers had often been recommended. In December 1845, such action was proposed by President Polk and in May 1846 the Congress approved "An Act to provide for raising a regiment of Mounted Riflemen, and for establishing military stations on the route to Oregon." Funds were provided to mount and equip the troops, to defray the expenses of each station, and to compensate the Indian tribes on whose lands these stations might be erected. The Mexican War delayed the projected building of forts on the Oregon Trail.
As news of the discovery of gold in California in 1849 was published throughout the nation, and the resulting fevered preparations to trek westward the next spring increased the urgency of completing the chain of forts. In March, United States Adj. Gen. Roger Jones directed Gen. D. E. Triggs at St. Louis to carry out establishment of the second post "at or near Fort Laramie, a trading station belonging to the American Fur Company." Lt. Daniel P. Woodbury, of the Corps of Engineers, was authorized to purchase the buildings of Fort Laramie "should he deem it necessary to do so."
On August 31, 1889 the usefulness of the installation for military purposes had ended and an order to abandon Fort Laramie would be issued. On March 2nd the last garrison of the post would leave. A public auction was held on April 9th to sell the remaining property and buildings.
