XXIII. THE FATAL CIPHER.

The disgruntled Spaniards continued to threaten war. Governor Claiborne ordered Casco Calvo and Intendant Morales to quit the territory of New Orleans. Soon after this a body of Spanish troops, supported by Indian allies, a.s.sembled on the Sabine to menace the American borders. In August a force actually crossed the Sabine and advanced to Bayou Pierre, near Natchitoches, a hundred and twenty miles west of Natchez.

General Wilkinson came from St. Louis to Natchez, and presently advanced to Natchitoches at the head of a body of one hundred regulars and five hundred militia. Late one afternoon in October word was brought to Wilkinson in his tent that a young man of fine appearance had arrived in camp, desiring to enlist as a volunteer. The general gave orders to bring the man into his presence. The would-be soldier was conducted immediately to headquarters, and there he imparted his name and the real cause of his coming, his representation to the sentinel being a ruse.

"Ah, you are Colonel Burr's confidential secretary; you have travelled far and must be exhausted. You bring doc.u.ments for me?"

"Yes, sir; my credentials are included with matters more important."

"You know the contents of the enclosure?"

"Only the general import. The sender of these missives has divulged much to me. You may trust me."

"I trust you implicitly, Mr. Swartwout. The emba.s.sy on which you come is of a delicate character, requiring discretion--as secret service always does."

The general opened the package, and found that it contained three separate papers. The first was a letter introducing Samuel Swartwout, and vouching for his prudence, courage and trustworthiness. The other two papers were in hieroglyphics. Wilkinson, smiling graciously, turned to the messenger.

"Perhaps I had best be alone while I examine the other doc.u.ments. I will see that you are made comfortable."

An officer was summoned. "Captain Danvers, this gentleman is my guest.

Please see that he is suitably quartered and provided with a seat at my table. He is the son of an old military acquaintance of mine."

The cipher agreed upon by Wilkinson and Burr was a composite of arbitrary signs and of numerals representing letters of the alphabet.

The first riddle read by Wilkinson was a private letter to Burr from General Dayton. Part of the contents ran thus: "Under the auspices of Burr and Wilkinson, I shall be happy to engage, and when the time arrives, you will find me near you. Write and inform me, by first mail, what may be expected from you and your a.s.sociates.... Wealth and honor, courage and union, Burr and Wilkinson! Adieu."

The other communication was from Burr himself.

"Your letter, postmarked 13th May, is received. At length I have obtained funds and have actually commenced. The eastern detachments from different points, and under different pretences, will rendezvous on the Ohio, 1st of November. Everything internal and external favors our views. Naval protection of England is secured. Truxton is going to Jamaica, to arrange with the admiral on that station. It will meet us at the Mississippi. England, a navy of the United States, are ready to join, and final orders are given to my friends and followers. It will be a host of choice spirits. Wilkinson shall be second to Burr only, and Wilkinson shall dictate the rank and promotion of his officers.

Burr will proceed westward 1st of August, never to return. With him go daughter and grandson. The husband will follow in October, with a corps of worthies. Send forwith an intelligent friend, with whom Burr may confer. He shall return immediately with further interesting details; this is essential to harmony and concert of movement. Send a list of all persons known to Wilkinson west of the Alleghany Mountains, who could be useful, with a note delineating their character. By your messenger send me four or five of the commissions of your officers, which you can borrow under any pretence you please.

They shall be returned faithfully. Already are orders given to the contractor to forward six months' provisions to points Wilkinson may name; this shall not be used until the last moment, and then under proper injunctions. Our project, my dear friend, is brought to a point so long desired. Burr guarantees the result with his life and honor, with the lives and honor and the fortunes of hundreds, the best blood of our country. Burr's plan of operation is to move down rapidly, from the falls, on the 15th of November, with the first five hundred or thousand men, in light boats now constructing for that purpose, to be at Natchez between the 5th and 15th of December, there to meet you, there to determine whether it will be expedient in the first instance to seize on, or pa.s.s by, Baton Rouge ... on receipt of this send Burr an answer ... draw on Burr for all expenses, etc. The people of the country to which we are going are prepared to receive us; their agents, now with Burr, say that if we will protect their religion and will not subject them to a foreign power, that in three weeks all will be settled. The G.o.ds invite us to glory and fortune; it remains to be seen whether we deserve the boon. The bearer of this goes express to you; he will hand a formal letter of introduction to you, from Burr; he is a man of inviolable honor and perfect discretion, formed to execute rather than project, capable of relating facts with fidelity, and incapable of relating them otherwise. He is thoroughly informed of the plans and intentions of ----, and will disclose to you, as far as you inquire, and no further; he has imbibed a reverence for your character, and may be embarra.s.sed in your presence; put him at ease, and he will satisfy you."

The eastern sky was flushed faintly with morning red before the general finished deciphering this long message. Wilkinson saw that he could no longer maintain an equivocal att.i.tude, but must either yield positively to Burr's proposals or denounce them. Early in the day he summoned the messenger to his tent for a private interview.

"My dear sir," said the general, "you should be proud to be recommended by such a man, in such language. Burr has absolute confidence in your honor, fidelity, veracity and courage."

Swartwout answered with feeling and dignity.

"I hope I may prove myself worthy of his confidence and of yours. I would not hesitate to risk my life for Colonel Burr or for his best friend, General Wilkinson."

"That is very n.o.ble of you. Tell me, now that you are rested and refreshed after your long journey, by what route did you come?"

"I came straight from Pittsburg, thence westward through Ohio and Kentucky to Louisville, and from there on to St. Louis, expecting to find you at that post. Learning that you had gone down the Mississippi I followed in a skiff. I have been more than two months on the way from Philadelphia to Natchitoches and have travelled fully fifteen hundred miles."

"The doc.u.ment in your custody justified the difficult journey, Mr.

Swartwout. What information did you gather in the progress of your trip, concerning our preparations?"

"I learned that, with the support of a powerful a.s.sociation extending from New York to New Orleans, Colonel Burr is levying an armed body of seven thousand men, with the view of carrying an expedition against the Mexican provinces. Five hundred men are to descend the Alleghany, for whose accommodation boats are ready."

"What will be the course of action?"

"This territory will be revolutionized. Some property will be seized in New Orleans, I suppose. Our boats will be ready to leave in February for Vera Cruz; the troops will march from there to the City of Mexico."

"Does Colonel Burr know there are several millions of dollars in the Bank of New Orleans?"

"We know that full well."

"Is it the intention to seize upon the deposits of private individuals?"

"We mean to borrow, not to violate private property. We must equip ourselves in New Orleans; we expect naval protection from Great Britain. Of course, general, everything depends upon your co-operation."

"Mr. Swartwout, the plans set forth in Colonel Burr's schedule are admirable! You will readily perceive, however, that my part in carrying them into effect must be manipulated with caution. I am surrounded, as you see, by officers whom I must manage discreetly. It is impossible that I should ever dishonor my commission. If I cannot join in the expedition, the engagements which the Spaniards have prepared for me in my front might prevent my opposing your operations.

Do you understand me?"

Burr's agent understood. He interpreted Wilkinson's language to mean much more than it said, attributing to the commander a profound sagacity which imposed reticence for causes beyond an ordinary man's ken. His unsuspicious mind had been schooled by Burr to believe implicitly in Wilkinson.

Swartwout was under engagement to join Burr at Nashville, and he pressed for a letter which he might deliver to his chief. This request Wilkinson evaded. Promising to return Burr a speedy answer, he detained the envoy under various pretexts, bestowing upon him every hospitable attention, and finally dismissed him with oral messages, after having consumed ten days of his time.

Three days subsequent to the departure of Swartwout another messenger, as secret and more swift, was dispatched from Natchitoches, bearing to Washington City from the commander-in-chief, a full disclosure of the plans of conspiracy, and fastening the charge of treason on Aaron Burr. All the machinery of civil and military executive power was put in motion in the districts over which Wilkinson's authority extended.

The information forwarded by Wilkinson's messenger reached Washington City November 25, 1806. It was by no means the only evidence the President had received, impeaching the loyalty of the eminent politician. Daviess had written, and Morgan had written, and the veiled witness in black had come in person with the facts reiterated in Wilkinson's letter of exposure.

The President issued a proclamation, "warning and enjoining those who had been led to partic.i.p.ate in the unlawful enterprise, to withdraw without delay, and requiring all officers, civil and military, of any one of the States or Territories, to be vigilant, each within his respective department, in searching out and bringing to punishment all persons engaged or concerned in the undertaking."

XXIV. THE MIDNIGHT DEPARTURE.

The first snowstorm of early winter was whirling its flaky showers over the frozen fields and through the naked woods of Bacchus Island.

The short day was nearing a dismal close. Harman Blennerha.s.sett paced uneasily to and fro within the narrow confines of his study. His face was haggard, his general aspect that of a man hara.s.sed and hopeless.

Yet he seemed idle and without sense of responsibility for the future.

His air indicated irresolution, ennui, mild disgust of the world and of himself. He took down Homer, brushed the dust from the covers, and then replaced the volume on its shelf. He gave the gla.s.s cylinder of his electrical machine a turn or two, and was for the moment gratified to elicit a faint spark, a feeble snap of blue fire, which clicked from the "receiver" to his knuckles. His eye dwelt fondly for a few seconds on the air-pump, but wandered from that to the telescope, and finally took cognizance of an apparatus for weighing heavy articles.

This was provided with a small platform, upon which the recluse philosopher stepped, to determine his exact weight. He was busied in this personal experiment, when a visitor was announced and ushered into his _sanctum sanctorum_.

"I beg pardon! Do I intrude?" said the caller, a man of official bearing, who gave the name of Graham.

"Not in the least, Mr. Graham. I have been taking my weight, and I beg you to excuse me until I note the precise number of pounds and ounces.

My memory is treacherous. I make it a rule to ascertain my weight and my height several times a year, but I can never remember either, an hour after. I actually forget the date of my own birthday and how old I am."

"That is owing, doubtless, to the fact that your mind is absorbed in important things," said Graham, not very tactfully. "I make bold to come to your house, Mr. Blennerha.s.sett, uninvited, but not without warrant. You are, I am informed, a partner of Aaron Burr in certain enterprises now much talked of. It is of this Wachita expedition that I wish to speak with you."

"Speak freely, Mr. Graham. Colonel Burr intimated that you would probably join us. Here are letters giving recent information. Read for yourself."

Graham glanced over a number of communications containing secrets that Blennerha.s.sett, had he been a man of ordinary forethought, would not have trusted out of his own hands. Among the letters was one from Burr, giving a brief account of his troubles in Frankfort. "You perceive, my dear sir," so ran the lines, "that this step will embarra.s.s me in my project of the Wachita settlement, and will deprive me of the pleasure of seeing you at your own house." Graham smiled gravely at the guileless simplicity of the man who had not hesitated to take a stranger into his confidence, unquestioned and unsuspected.
