Most of the materials on which this essay is based are to be found in the manuscript collection entitled “Diplomatic, Consular and Domestic Correspondence of the Republic of Texas,” now in the State Library at Austin. Except in cases where the notes indicate otherwise, the letters and papers referred to belong to this collection. Some whose originals do not exist in the collection have been published in Niles' Register. For the sake of convenience and economy in printing, the references, instead of being completely distributed to support detailed statements, are, for the most part, grouped in notes at the ends of the paragraphs.
