The next day, “in view of the above cited declarations,” the Commandant ordered four persons, Joseph Charpentier, LaForge, George Ruddell, and Don Robert McCoy, “Captain of the Militia,” to proceed to Little Prairie—a distance of about thirty miles—and there meet a division of regulars commanded by Corporal Felipo Canot, who had been ordered to the scene. Upon their arrival at the place further investigation convinced the officers that the new suspects were Samuel Mason and some of his followers, and that about half the number had left the Lesieur house and moved over to a house owned by Francois Langlois. Realizing that the pursuing party would soon be scented by the suspects, it was decided to invade the two houses early in the morning.

At six o’clock in the morning George Ruddell informed Captain McCoy that the Masons had their horses saddled and loaded with baggage and were on the point of leaving for New Madrid, but Samuel Mason, known as “Father Mason,” hearing that the interpreter was in town, expressed a desire to see him and explain that he wished to go to New Madrid to “justify himself” and clear himself of the crimes of which he was “falsely accused.” Captain McCoy, George Ruddell, and the interpreter walked to the house occupied by Samuel Mason and suggested to him that, in view of his intention to volunteer a justification, he and those of his people with him would do well to go over to the house occupied by his other associates where he would be given a hearing and could make explanations which would be forwarded to the Commandant at New Madrid. To this Mason consented and by eight o’clock his party, consisting of six men, one woman, and three children, was assembled in the Lesieur house which, unsuspected by the Masons, was guarded by concealed militia. Samuel Mason, turning to Captain McCoy, immediately referred to the “unjust imputations” made against him and his people. The Captain expressed the opinion that his explanation and justification had better be made in person to the Commandant. A signal was given by Captain McCoy, and before the Masons realized it, they were “in handcuffs and chains.”

Then, in the words of the clerk, “We immediately asked said prisoners their names and the father or oldest gave his as Samuel Mason;” those of his four sons, in order of age, were given as Thomas, John, Samuel Jr. (about eighteen years of age) and Magnus Mason (about sixteen years of age). Another man called himself John Taylor (later in the trial known as John Setton). The woman had three children with her and gave her name as Marguerite Douglas, wife of John Mason. Upon being questioned by McCoy and Charpentier, Samuel Mason answered that they had come from Nogales (Vicksburg) and intended to establish themselves in or near Little Prairie, in accordance with a passport given him. When asked to produce a passport issued “by the authorities of the locality from whence he came,” it was discovered he had “none other than the one we ourselves had given, dated New Madrid, March 29th, 1800.” This he surrendered to Captain McCoy, who agreed with the other officials present that it was genuine.

Facsimile of Passport issued to Samuel Mason

Written in French and issued by the Spanish Commandant of the District of New Madrid, March 29, 1800

The original passport was inserted between two leaves of the record book where it has ever since remained. The following is a translation:

“New Madrid, March 29th, 1800.

“Whereas Samuel Masson, Esqr. has expressed a wish to settle in this district and wishes to arrange his business affairs, We, Don Henri Peyroux de la Coundreniere, Captain of the Armies of His Majesty, Civil and Military Commander of this Post and District of New Madrid, hereby grant permission to said Samuel Masson to proceed to Natchez per boat, and on his return from there, said Samuel Masson may select a suitable place in this District for himself and family. He, Samuel Masson, having by oath attested his loyalty and fidelity to us, we pray that no hindrance be placed to his proposed journey.

“Henri Peyroux

“Approved and marked with the flourish of our signature.”

“We told them,” continues the record, “in order that none of their effects be lost or strayed an inventory of same would be made at once ... and at two o’clock in the afternoon we proceeded with the above-named inventory.” This work required almost two days. Every item was carefully examined and tabulated. There were eight horses, new and old clothes, many yards of silk, muslin and cotton, old and new pistols and guns, “a field stove,” a box of salt, three horns of powder, six barrels of flour, English cutlery, various other imported goods and more than a hundred other items, and seven thousand dollars in United States money of various denominations, of which the series number and amount of each was noted.

The following morning, while the inventory was being made, Samuel Mason, on behalf of his people, applied for the return of certain utensils and clothing of which his people had immediate need, and asked for “a pro and con settlement” with the citizens of Little Prairie. These requests were granted. On the 16th, the prisoners, with their property and a military guard, arrived at New Madrid. How they were transported is not stated.
