grattan fight

The Moncravie House was a small trading establishment constructed in 1856 on the Laramie River approximately twelve miles upstream from Fort Laramie, in what is now Goshen County, Wyoming.

After the Grattan Fight forced Platte River traders to Fort Laramie in 1855, Seth Ward and William Guerrier built a trading post just across the river. Ward became the fort’s sutler in 1857, anchoring one of the corridor’s most successful trading partnerships until 1863.

From 1850 to 1854, fur trader and interpreter Joseph Bissonette ran an independent trading post on the North Platte River, serving emigrants and Lakota bands alike. He later worked as a ferryman, bridge partner, and government official through the Oregon Trail’s final violent years.

For twelve years, John Baptiste Richard’s toll bridge and trading post near present-day Evansville was the upper North Platte’s busiest crossing, hosting emigrants, soldiers, and the Pony Express. Known to travelers as “Reshaw’s Bridge,” it gave way to Fort Caspar in 1865.
