The secret which underlay Pike's ostensible instructions from General Wilkinson, and the mystery which is supposed to have enshrouded his movements on this portion of his second expedition, are fully discussed in my notes, at various points in Pike's narrative or in my Memoir, where the subject obtrudes. Without going into any particulars here, it is to be said simply that Pike may have been ordered to proceed to Santa Fé--or as near that capital of Spanish New Mexico as he could go with the force at his command--without being informed of whatever ulterior designs the general of the army may have entertained. III. Pike was captured in his stockade, with the few men he had left about him, by Spanish dragoons, under the orders of General Allencaster, then governor of New Mexico. The message he received from his captors was disguised under the form of a polite invitation to visit the governor at Santa Fé. On the 27th of February, 1807, he left his post as a prisoner in the hands of a half-hostile foreign power, accompanied by the remnant of his men. They were treated with great forbearance--nay, with distinguished consideration; nevertheless, Pike was brought to book before the authorities, and required to explain how he had happened to invade Spanish territory with an armed force. Governor Allencaster then ordered him to report to General Salcedo at Chihuahua; he was accordingly escorted by the military down the Rio Grande from Santa Fé to El Paso, and thence by the usual route southward, in what was then New Biscay, to the first named city. From this capital he was conducted, still under guard, through a portion of what is now the State of Durango, around by the Bolson de Mapimi, thence northward throughout Coahuila, and so on to San Antonio. Continuing through Texas, he was finally delivered out of the hands of his Spanish hosts and captors, on crossing the river which in part bounds our present State of Louisiana; and ended his long peregrination at Natchitoches, among his own countrymen. At this point the author's narrative ends abruptly, so far as any itinerary of his movements is concerned. We are not even told what became of the men who did not accompany him to Natchitoches--those who were left behind when he started from the Rio Conejos, either at that point, or in the Wet Mountain valley, or on the Arkansaw. It had been understood, and was fully expected, that they were all to follow him through Mexico under Spanish escort. It is probable that they did so, and that all were finally restored to the United States. But at the last word we have on the subject from Pike himself, eight persons were still detained in Mexico.
