Benjamin Bonneville - Early Career

Early Career

In 1813 the young Bonneville received an appointment to the United States Military Academy at West Point, New York. He graduated after only two years, receiving a commission as brevet second lieutenant of light artillery. In his early career, he served at posts in New England, Mississippi, and at Fort Smith in the Arkansas Territory.

In 1824, he was transferred to Fort Gibson in the Indian Territory and promoted to Captain. While traveling to France, he was a guest of General Lafayette. After returning from France, he was transferred in 1828 to Jefferson Barracks in Missouri.

While in Missouri, Bonneville was inspired by the writing of Hall J. Kelley, as well as editorials in the St. Louis Enquirer (edited at the time by Thomas Hart Benton) to join in the exploration of the American West. Bonneville met with Kelley, who was impressed by him and appointed him to lead one of the expeditions to the Oregon Country; it was scheduled to leave in early 1832. The lack of volunteers for the expedition forced the delay and eventual cancellation of the expedition, leaving Bonneville unrequited in his ambitions.

To pursue his desire to explore the west, he petitioned General Alexander Macomb for a leave of absence from the military, arguing that he would be able to perform valuable reconnaissance among the Native Americans in the Oregon Country, which at the time was under a precarious joint occupation of the U.S. and Britain. It was largely controlled by the Hudson's Bay Company. Macomb granted his request, a 26-month leave running from August 1831 to October 1833, and instructed him to gather all information that might be useful to the government. In particular, he was to pose as a fur trader and find out the natural history of the region, its climates, soils, geography, topography, mineral production, geology, and the character of the local tribes. Expenses for his exploration were paid by private donors, including Astorian Alfred Seton and possibly John Jacob Astor.
