Benjamin Bonneville was a brave soldier and a famous explorer. 

Bonneville had a big dream to see the American West. He wanted to learn about the land and its people. He asked his leader, General Alexander Macomb, for a leave of absence. The General said yes for 26 months. Bonneville was told to act like a fur trader. He needed to study the soil, the weather, and the mountains. He also had to learn about the local tribes. Private people paid for his expensive trip. One man who helped was John Jacob Astor. This mission was a very important job for the government.
In May 1832, the great expedition finally began. Bonneville led 110 men across the wild country. They traveled through places like Wyoming and the Green River. They even built a trading post named Fort Bonneville. Some mountain men called it "Fort Nonsense" because it was not used for trading. In 1833, Bonneville explored the Snake River in Idaho. He met a young Shoshone boy named John Enos. Enos became a scout for other explorers later on. Bonneville also sent men to find a path to California. They found a way through the mountains called the California Trail. This path helped many people reach gold fields later.
Life was not always easy for Bonneville during his travels. He tried to trade with the Hudson's Bay Company. However, their leaders often refused to do business with him. This made it hard to get food and supplies. He spent some winters living with the Shoshone people. When he finally returned home, he found out his military job was gone. He had to work very hard to get it back. He eventually succeeded in 1836. He went on to fight in the Mexican-American War. He also served during the Civil War. He rose to the high rank of brigadier general.
Bonneville became a household name because of his stories. He met a famous writer named Washington Irving in New York. Irving loved the tales of the West. They made a deal for $1000 to write a book. Irving used Bonneville's maps and notes for the story. The book was called "The Adventures of Captain Bonneville." It was published in 1837 and made him very famous. Many things are named after him today. There is a Bonneville County in Idaho and even a crater on Mars. He lived to be 82 years old. He is buried in a cemetery in St. Louis. 
Benjamin Louis Eulalie de Bonneville was a significant figure in the history of the American West. He served as an officer in the United States Army and worked as a fur trapper and explorer. 
Bonneville's life began in or near Paris, France, in 1796. His parents were Nicholas Bonneville, a publisher, and Marguerite Brazier. When Benjamin was seven, his family moved to the United States. A man named Thomas Paine paid for their passage. Paine was the godfather to Benjamin and his brothers, Louis and Thomas. After Paine died in 1809, he left an estate to Marguerite. This included a 100-acre farm in New Rochelle, New York. This inheritance allowed her to educate her sons.
In 1813, Bonneville entered the United States Military Academy at West Point. He graduated in only two years as a brevet second lieutenant of light artillery. He served at various posts in New England, Mississippi, and the Arkansas Territory. By 1824, he was promoted to captain at Fort Gibson. During a trip to France, he met General Lafayette. Later, in 1828, he moved to Jefferson Barracks in Missouri. In Missouri, he felt inspired to explore the American West. He read writings by Hall J. Kelley and editorials in the St. Louis Enquirer.
Bonneville sought permission from General Alexander Macomb to explore the West. He argued that he could perform reconnaissance in the Oregon Country. At that time, the region was under joint occupation by the U.S. and Britain. The Hudson's Bay Company largely controlled the area. Macomb granted a 26-month leave from August 1831 to October 1833. Bonneville was instructed to gather useful information for the government. He was to pose as a fur trader to study the natural history. He needed to document the climate, soil, geography, and mineral production. He also had to study the local tribes. Private donors, including Alfred Seton and possibly John Jacob Astor, paid his expenses.
His most famous expedition began in May 1832 with 110 men. He was joined by lieutenants Michael Cerre and Joseph R. Walker. The trip was financed by John Jacob Astor. The group traveled from Fort Osage up the Missouri River. They crossed present-day Wyoming and reached the Green River in August. There, they built a trading post called Fort Bonneville. Some mountain men called it "Fort Nonsense" because it was never used for trading. In 1833, Bonneville explored the Snake River in present-day Idaho. He met a young Shoshone guide named John Enos. During this time, he sent Joseph Walker to find a route to California. Walker discovered a path through the Sierra Nevada mountains. This became the California Trail, used later by gold seekers.
Exploring the West presented many difficult challenges. The Hudson's Bay Company, led by John McLoughlin, made business difficult. McLoughlin forbade his traders from working with Bonneville. This meant Bonneville struggled to trade or find supplies. He faced many rejections at Fort Nez Perces and Fort Vancouver. These difficulties caused him to stay longer than his 26-month leave allowed. When he finally returned to Missouri in 1835, he found his military commission had been revoked. He spent much time petitioning the Secretary of War, Lewis Cass, to get his job back. He was successful in 1836.
Bonneville continued a long and distinguished military career. He served in the Mexican-American War and was part of the occupation of Mexico City. He later became a colonel of the 3rd Infantry Regiment in 1855. During the Civil War, he served in Missouri and St. Louis. He was eventually honored as a brevet brigadier general. After retiring for a second time in 1866, he moved to Fort Smith, Arkansas. He married Sue Neis there. Bonneville died in 1878 at the age of 82. He is buried at Bellefontaine Cemetery in St. Louis. 
His adventures reached a wider audience through literature. While in New York, Bonneville met the famous writer Washington Irving. Irving was interested in the stories of the West. They agreed on a deal where Bonneville provided maps and notes for $1,000. Irving used these to write "The Adventures of Captain Bonneville," published in 1837. This book made Bonneville a celebrity. Today, his name is found on many things. These include Bonneville County in Idaho and even a crater on Mars. His legacy lives on through the trails he helped map and the stories he shared.
