Monroe wrote to Cevallos, April 9, that he considered “the negotiation as essentially terminated by what has already occurred.[22]... Should his Majesty’s government think proper to invite another issue, on it will the responsibility rest for the consequences. The United States are not unprepared for, or unequal to, any crisis which may occur.” Three days later he repeated the wish to “withdraw from a situation which, while it compromits the character of our government, cannot be agreeable to ourselves.”[23] Cevallos took no notice of the threats, and contented himself with repelling the idea that the blame of breaking off the negotiation should rest upon him. Nevertheless he hastened to record the opinion of his Government in regard to the last claim of the United States,--the Texan boundary. Here again Cevallos followed the guidance of Talleyrand. The dividing-line between Louisiana and Texas, he said, ought to be decided by the line between the French and Spanish settlements. The French post of Natchitoches, on the Red River, was distant seven leagues from the Spanish post of Nuestra Señora de los Adaes; and therefore the boundary of Louisiana should run between these two points southward, along the watershed, until it reached the Gulf of Mexico between the Marmentou and the Calcasieu,--a boundary which deprived the United States not only of Texas, but of an important territory afterward included in the State of Louisiana.[24] Eager as Monroe was to close the negotiation, he could not leave this note without reply; and accordingly he consumed another week in preparing more complaints of Cevallos’ dilatory conduct, and in proving that Texas was included in the grant made by Louis XIV. to Anthony Crozat in 1712. After disposing of that subject, he again begged for a conclusion. “As every point has been thus fully discussed, we flatter ourselves that we shall now be honored with your Excellency’s propositions for the arrangement of the whole business.”[25] He flattered himself in vain; ten days passed without an answer. May 1, at a private interview, he tried to obtain some promise of action, without better result than the usual obliging Spanish expressions; a week afterward he made another attempt, with the same reply, followed on Monroe’s part by an offer to concede even the point of dignity. “Would Señor Cevallos listen to a new and more advantageous offer on the part of the United States?” Cevallos replied that such a step would be premature, as the discussion was not yet ended.[26] Monroe had no choice but to break through the diplomatic net in which he had wound himself; and at length, May 12, 1805, he sent a general ultimatum to the Spanish government: If Spain would cede the Floridas, ratify the claims convention of August, 1802, and accept the Colorado as the Texan boundary, the United States would establish a neutral territory a hundred miles wide on the eastern bank of the Colorado, from the
