Letter from Thomas Jefferson to William Dunbar

Thomas Jefferson to William Dunbar, March 3, 1803

Overview:
After thanking William Dunbar for earlier correspondence, including Martin Duralde's report to the American Philosophical Society, Thomas Jefferson expresses hopes that American rights to the Mississippi River can be maintained without war; the President also anticipates the acquisition of Native lands on the left bank of the river to "plant on the Missisipi itself the means of it's own defence."

Washington, Mar. 3. 1803.

Dear Sir
,

Your favr. of the 5th of Jan. has been duly recieved, and I have to return you thanks for the two vocabularies. The memoir of Mr. Duralde has been forwarded to the Philosophical society. We shall be happy to see your history of the Misisipi Maps: compleated, as it is becoming one of the most interesting parts our country, the only one where some of the Tropical productions can be numbered among ours. Mrs. Trist had only a little mistaken the information I gave her; which was not that you were removing altogether, but that you meant shortly to take a trip to England, which I had understood from some other persons is not from yourself.

The late interruption of our commerce at New Orleans by the Spanish Intendant, combined with the change of proprietors which Lousiana certainly, and the Floridas possibly are immediately to undergo, have produced a great sensation here while some have wished to make it the immediate cause of war which might derange our finances & unharness the administration of the government, which in the state of their political passions would be a counter-veil for the most serious public calamities; we have formed what we believe a more certain, & more speedy means of reestablishing permanently the rights & conveniences of our commerce. Whether we may succeed in the acquisition of the island of N. Orleans & the Floridas peaceably for a price far short of the expence of a war, we cannot say. Butt that we shall obtain peaceably an immediate & firm reestablishment of all our rights under the Spanish treaty every circumstance known to us tends us to believe. If contrary to expectations, war should be necessary to restore our rights, it is surely prudent to take a little time for availing ourselves of the division of Europe to strengthen ourselves for that war. Nothing but the failure of every peaceable mode of redress, nothing but dire necessity, should force us from that path of peace which would be our wisest pursuit; to embark in

broils and contentions of Europe, and become a satelite to any power there, yet this must be the consequence, if we fail in all peaceable means of reestablishing our rights. Were we to enter into the war alone the Missisipi Maps: would be blockaded at least during the continuance of that war, by a superior naval power, and all our Western states be deprived of their commerce unless they would surrender themselves to the blockading power. Great endeavors have been used from this quarter to enflame the Western people to take possession of New Orleans, without looking forward to the use they could make of it with a blockaded river but I trust they will be sensible that a peaceable redress will be the quickest & most for their interests. We shall endeavor to procure the Indian right of soil, as soon as they can be prevailed on to part with it,of the whole left bank of the Missisipi Maps: to a respectable breadth, and encourage it's prompt settlement; and thereby plant on the Missisipi Maps: itself the means of it's own defence, and present as strong a frontier on that as our Eastern border.

I pray you to accept assurance of my great esteem and respect.
Th: Jefferson
