Extract of a letter from an officer in the American service, to his friends in Frankfort, Ky. dated,

Natchitoches, Sept. 23.

"A Spaniard arrived here yesterday, who made oath before Dr. Sibly, a justice of the peace, that he was an artillerist some time since at St. Antoine, in the service of the Republicans, and that the corps to which he had been attached had joined the royal party, much against his inclination: and that Cols. Manshac, and Bernard, with Capts. Gonsalves and Hannandes, (all in the republican interest) had been empowered to go to the United States with instruction to treat for arms and ammunition, saying that the republicans had upwards of three millions of dollars, which the United States government could have by sending a vessel round to bring it away and that gov. Cordero, who commands some where in the interior, learning of the expedition, gave intimation of it to gov. Salcedo, at St. Antoine, with an order to send out patrols to intercept the party, if possible. That himself was one of the patrols sent--that he deserted his party and joined Manshac-- that they then crossed the Sabine and had gotten within 50 miles of this place (Natchitoches) when they were overtaken by a large party, who surrounded the house (Mr. Bernard's) in which Manshac and his party had quartered for the night--that himself made his escape with much difficulty. He expects Manshac and party were either killed or taken.

"The report is generally believed here as the Spaniard is intelligent.

"He moreover states, that Manshac had an intercepted letter from Governor Cordero to some of the commandants of the Royal party, in which he says "that he intended soon to march against Fort Claiborne with a force of 600 men, in consequence of our interference in Florida." Mexico is besieged with a large party of Republicans--they are badly armed, the Royalists possess the magazines. The American captain R. Smith has been killed in the republican service."
