In 1854, Ulysses S. Grant, then a young Lt., was stationed at Fort Humboldt. He was under the command of Brevet LtCol. Robert C. Buchanan. There was no love lost between the two and after four months of enduring the harsh and lonely Humboldt environment, Grant resigned from the army until later called back to duty by President Lincoln. He became the commanding general of the Union forces during the Civil War and later served two terms as President of the United States.
