FORT BENTON

A short history of Fort Benton

Established in 1846 as Fort Lewis and relocated 15 miles downstream in 1847 by Alexander Culbertson, who worked for Auguste Chouteau and Pierre Chouteau, Jr. of St. Louis, the original fort was the last fur trading post on the Upper Missouri River, which soon made it an important economic center. For 30 years, the port attracted steamboats carrying goods, merchants, gold miners and settlers, coming from New Orleans, Memphis, St. Louis, Hannibal, Bismarck, and Kansas City, among other places. As the eastern terminus for the 642-mile-long Mullan Road, completed by the United States Army in 1860, and at the head of navigation of the Missouri River, Fort Benton was part of the overland link between the Missouri and the Columbia River, with its own head of navigation at Fort Walla Walla in Washington. Twenty thousand migrants used the road to travel to the Northwest in its first year. It became an important route for miners from both directions going into the interior of Idaho and north to Canada. Steamboat travel to Fort Benton from St. Louis, Missouri, helped broadly fuel the development of the American West between 1860 and 1890, when it was supplanted by railroad transport. The river was an important route for miners to the newly discovered gold fields of southern Montana at what became Bannack and Virginia City beginning in 1862, and Helena beginning in 1865.

With the decline of the fur trade, the American Fur Company sold the fort to the Northwest Fur Company in 1865, and the fort became a U.S. Army post from 1868 until the army units departed in 1881. Founder Alexander Culbertson formally named it Fort Benton on Christmas Day 1850, in honor of Senator Thomas Hart Benton of Missouri. Beginning in the early 1860s, with the arrival of the first steamboats, a town began to grow up around the fort. Besides being one of the most important ports on the Missouri-Mississippi river system, Fort Benton was once the "World's Innermost Port" – the furthest point of navigable water on the Missouri River. It was served by numerous well-known "mountain boats" (designed specifically for the Missouri River), including the Yellowstone and the Far West, and their famed captains, Joseph LaBarge and Grant Marsh, respectively.

Fort Benton's importance in trade was superseded by the construction of transcontinental railroads in the late 19th century. In 1867, Fort Benton was the site where Union General Thomas Francis Meagher, then acting governor of Montana Territory, fell overboard from his steamboat and drowned in the river; his body was never recovered.
