Washington Irving 
Astoria; Or, Anecdotes of an Enterprise Beyond the Rocky Mountains [EPUB ebook] 

In 1811 a group of American traders built a fort at the mouth of the Columbia River, named Fort Astoria in honour of its financier, John Jacob Astor. Envisioned as the spur of a fur-trading empire, by 1813 the project was a business failure and the fort was surrendered to the British. But in its short life Astoria rendered incalculable benefits to public understanding of the Great Northwest. The exploration of trade routes, the description of various Indian tribes and their customs, and an American claim on the Northwest coast were among many of its legacies. (Goodreads)
