“From these considerations, and my own personal observations, I am, therefore, disposed to believe that two posts established by the government, one at the mouth of the Yellowstone River, and one on the Arkansas, would completely protect all our people in every section of the great wilderness of the West; while other advantages, at least with regard to one of them, confirm and urge the suggestion.  A fort at the mouth of the Yellowstone, garrisoned by fifty men would be perfectly safe.  The establishment might be constructed simply with a view to the stores, stables for the dragoons’ horses, and quarters for the regular garrison; the rest being provided with sheds or lodges, erected in the vicinity, for their residence during the winter months.”
