As I promised on my arrival in the United States, to give their friends an account of their situation, I could conceive no more certain and expeditious a method than through the medium of your Herald, and therefore wish you to give this communication publicity; and hope the Editors of the Gazettes of the states in which the friends of those unfortunate young men may belong, will republish it, that their connections may receive the melancholy assurances of some being in existence, and that others are beyond the power of tyranny and oppression. I am, &c., [Signed] Z. M. PIKE. In a late involuntary tour which I made through part of his Catholic majesty's dominions of New Spain, whilst at St. Affe [Santa Fé], the capitol of N. Mexico and Chihuahua, I met with a number of the poor unfortunate companions of the deceased Nolan. One of whom gave me the following cursory statement of their treatment, &c. since their being taken, and on their joint application, I addressed a letter to his excellency Nemeio [_sic_] Salcedo, in their favor, of which an extract is subjoined, with the verbal reply of the general. "We crossed the Mississippi on the 1st day of November, 1800, at the Walnut hills [Nogales], and in January following arrived at the river Brassus [Brazos], in the provinces of Texus, and proceeded to build pens [for the capture of mustangs]. In March, 1801, we began to run wild horses, and having caught several hundreds of them we selected the handsomest and let the ballance go. On the 22 of March, we were attacked at break of day, by sixty regular troops, and two hundred and forty militia and Indians, with one field piece. Our commander, (Nolan) being killed, we capitulated in the evening, on the assurance that Nolan was killed, who only was to blame, we should be conducted to Naggadoches [Nacogdoches], from whence there was no doubt, we would have permission to return to our country, as soon as the circumstances were stated to the governor of St. Antonio. We remained there under promises and daily expectations of being released until July, when we were all put in heavy irons. "In August we were marched, in irons, to St. Antonio [Texas]; and in December through the province of Coqquella [Coahuila] and [New] Biscay, into the vice-royalty of Mexico, to the city of St. Louis Potosi, where we remained fourteen months, ironed, and in close confinement. In February, 1803, we were dispatched to Chihuahua, where after some time, our irons were struck off. From which to the present time, we have experienced various treatment, sometimes enjoying the liberty of the town, sometimes the barracks, and for three months in irons and close confinement.
