Chapter 17: The Pedregal

The dispatches arrived before dawn, and Polk had them open by candlelight.

His private secretary had arranged the official correspondence to the right, newspapers and lesser material to the left, and Polk worked through the official stack with the speed of a prosecutor — methodical, unsentimental, alert to the gap between what was written and what was meant. The Executive Mansion's upper floor held the night's heat long after sunrise. By seven o'clock the air pressed against the skin — woollen, sourceless, thick enough to taste, carrying the faint sweetness of the horse-yard below and something older beneath it, the damp plaster of walls that never fully dried in a Washington August. He had drunk two cups of coffee. The breakfast tray sat at the desk's corner, untouched.

Scott's preliminary dispatch — arrived three days prior, now read four times — yielded nothing new on the fifth reading. The General wrote of signal victories and the enemy in full retreat upon the capital and terms of armistice consistent with the honour of both armies, but the terms themselves were not enclosed. The word armistice occupied the third paragraph with the comfortable vagueness of a man who considered certain questions beneath him to answer directly. Whether the armistice signalled imminent Mexican capitulation or a pause in which Santa Anna was reconstituting his forces — Scott had written the dispatch in a manner designed to ensure precisely that uncertainty.

Polk set it aside and reached for the newspapers.

The New York Herald, date of the twelfth, eight days old. The front page led with a dispatch from a correspondent identified only as a gentleman recently arrived from Puebla:

SAN PATRICIO TRAITORS FACE JUSTICE — COURTS-MARTIAL UNDERWAY IN SCOTT'S CAMP — FIFTY MEN OF THE BATTALION CONDEMNED — IRISHMEN WHO FOUGHT UNDER THE MEXICAN FLAG TO HANG OR BE FLOGGED AT THE GENERAL'S DISCRETION

He read the first three paragraphs and stopped. The correspondent had names. He had numbers — forty-eight condemned, sentences divided between hanging and flogging, the floggings to be administered before the walls of Churubusco. He had attended at least one proceeding. He had expressed his opinions in language calculated to sell newspapers in New York, Boston, and Philadelphia, where the Irish Catholic vote resided in concentrations the Democratic Party could not afford to disregard.

If the Whig press reprinted this before the administration could shape the account — and they would, within the week — every Democratic ward captain from the Bowery to Southwark would face the question: Your President hangs Irishmen for the crime of conscience, and you ask us for our votes?

A sudden clenching seized him low in the abdomen, sharp enough to pull his breath short. He gripped the desk's edge and held until it passed. Thirty seconds. He released the wood and tasted copper at the back of his throat.

He took the dispatches from the official stack and sorted them by date. Scott's, the fourteenth. Marcy's routing memorandum, the fifteenth. The adjutant general's communication, the seventeenth.

Nothing about the San Patricio courts-martial. Not one word.

A newspaper correspondent had attended proceedings the War Department had not reported to the President of the United States. If the Senate called for an accounting — and Calhoun would, the moment the Herald reached Charleston — there would be no official record to produce. He would stand before the country as a president ignorant of his own army's justice.

He crossed to the door and opened it. The young secretary, Elias, was already at his outer desk.

"Find Mr. Walker. Tell him I require Secretary Marcy here within the hour. Not at the War Department. Here."

"Yes, sir."

"And bring me paper. The heavy stock."

He returned to the desk and wrote the summons himself, in his own hand, in the declarative sentences he reserved for communications that were not requests. He required a full accounting of every dispatch originating from the field between the first and the eighteenth of August — date of composition, date of transmission, date of receipt. He required it before the morning was out.

He sanded the note and sealed it. The newspaper lay open beside it. He did not read further.

---

Marcy arrived bearing a memorandum and the faint smell of pomade applied in haste.

He produced the document from his coat with the care of a man presenting his only defence, setting it on the desk's corner. Polk did not touch it. The Secretary of War's cravat was not quite level. The moisture above his lip had nothing to do with the heat pressing through the windows.

"Mr. President." Marcy drew breath. "I have prepared for your consideration an accounting of the relay difficulties between Veracruz and the capital — the courier stations, the condition of the roads—"

"Sit down, Mr. Marcy."

The chair scraped once against the floor.

Polk took the dispatches — Scott's, the correspondent's piece, the covering note — and arranged them in a column by date. The correspondent's article sat at the top. The official dispatch sat below it, three days younger. He let Marcy look at the column for the space of two full breaths.

"The Herald's man in Mexico has described the San Patricio courts-martial in sufficient detail that I could name the presiding officer. He has described the charges, the proceedings, and the anticipated sentences." A pause. "I have not, as of this morning, received a single line from your office on the subject. Senator Calhoun will have this newspaper by Friday. What answer shall I give him when he rises in the chamber to demand an accounting?"

"Sir, the relay from the field—"

"Has been managed in a fashion that ensures correspondents receive their material before this office receives its official intelligence." Polk's jaw set. The tendons in his neck drew taut above his collar. "That is not a difficulty of relay, Mr. Marcy. That is a policy of concealment."

Marcy's hand moved toward the memorandum. "I would ask you to examine—"

"I have examined the record." Polk rose and went to the window, turning his back to the room. Below, Pennsylvania Avenue shimmered — a dray moving toward the market, the rasp of its iron-rimmed wheels rising through the open casement, the shout of a drayman cursing his mule in a voice that carried the flattened vowels of the Tidewater. He let the silence extend until he heard the chair shift — that small, involuntary displacement of weight which betrayed composure purchased at considerable cost.

"The memorandum may stand in the record," Polk said, without turning. "I do not dispute that the roads are poor. I do not dispute the rainy season." He crossed back and stood over the desk. "You will, however, produce for my examination every private communication between the General's field headquarters and your office for the past sixty days. Not the official dispatches. The private letters."

The room held only the cry of a vendor below, the distant church bell marking the half-hour.

"Sir, those communications are—"

"Within the hour, Mr. Marcy. Or I shall send Mr. Walker to collect them, and the manner of that collection will constitute its own statement to the cabinet."

Marcy's mouth opened and closed. He was a lawyer before he was a soldier's administrator, and he understood precisely what that instruction uncovered — and what the alternative would cost.

"There is," Marcy said, lowering his voice as though the walls themselves might carry testimony, "a letter of the eighteenth of July. From the field. Addressed to this office. It is — in nature, a private communication. Concerning the negotiations."

"Concerning Mr. Trist."

Marcy did not answer.

"The General expressed his view," Marcy continued, each word placed with the deliberation of a man crossing a frozen river, "that Mr. Trist's conduct of the preliminary discussions exhibited — he used the phrase — considerable diplomatic capacity. He recommended that Washington afford the envoy wider latitude."

Polk stood motionless. The heat pressed against his collar, against the wool of his coat, against the skin of his wrists where they emerged from the cuffs.

"You received this letter on the eighteenth of July."

"Yes, sir."

"And you determined — you, the Secretary of War — that a communication from the commanding general in the field, recommending that the President's envoy be granted authority beyond his instructions, did not require the President's attention."

A fly worked itself against the windowpane in a small, repetitive assault, the dry scrape of it the only sound between them. Marcy said nothing.

"Bring me the letter. Bring me all of them." Polk sat down — and the sitting was worse than his standing had been, worse because it was deliberate, because it said the interview would continue, because it said Marcy was not dismissed. "And send to Mr. Buchanan. I want him here before noon. We have a commission to revoke."

The telegraph room in the War Department's lower floor smelled of galvanic acid and overheated copper, the apparatus having run long in the August heat. The ceiling pressed down with the indifference of a structure built for function rather than habitation. A single window gave onto the alley; it admitted a wedge of flat light and the sour reek of the canal, and nothing else.

Polk stood at the map table. He had come himself — the President descending to the lower floor at half past four, his secretary trailing behind — and the act carried its own weight. Buchanan had followed from the Executive Mansion without being summoned, which told Polk something about the Secretary of State's apprehension, though he had not yet determined whether it was the apprehension of a man who feared what was coming or the cannier unease of a man who already knew.

The clerk, a young man named Prewitt, had spread the decoded dispatch across the table. Beside it lay the survey map — brown ink rendering of the Rio Grande, the Gila, the disputed interior. Prewitt had marked the proposed boundary in red chalk.

Polk looked at the line.

It ran south of the Gila, as he had been told. He had expected that. What he had not expected — what he had refused to expect, because to expect it was to concede that the man he had dispatched was capable of such a betrayal — was the way the line curved westward, leaving the Mesilla Valley entirely on the Mexican side. Thirty miles of territory, in places. The southern wagon route to California. The Sonora road. The only practical corridor engineers had identified for a railroad from New Orleans to the Pacific.

Trist had surrendered it.

The relay behind him ticked in its slow, mechanical pulse. Polk traced the red chalk with one finger, following it from the point where it departed the river's course to the place where it rejoined, far north of where any honest reading of his instructions placed the boundary. The chalk was rough under his fingertip, granular, leaving a faint residue of red on his skin.

"Read me the indemnity figure," he said.

Prewitt found the passage. "Twelve million dollars, Mr. President. In three installments."

"My instructions specified fifteen."

"Yes, sir."

Buchanan stood at the table's far corner, his large frame angled so the lamplight fell on the dispatch rather than his face. He had said nothing since they descended the stairs.

"Mr. Buchanan." Polk did not look up from the chalk line. "You drafted the original instructions. You specified the boundary. You specified the indemnity. At what point did you authorise the envoy to concede the only railroad corridor between the Gulf and the Pacific?"

"I authorised nothing of the kind." Buchanan's voice was even — the evenness of a prepared answer delivered with the intention of being heard. "It must be acknowledged, however, that the circumstances in the field may have presented him with conditions that—"

"The Mexican commissioners presented conditions to a man who possessed instructions." Polk's finger struck the red line at the Mesilla Valley, and the sound of nail against wood was sharp in the small room. "He chose to disregard those instructions. The question is not what Mexico demanded. The question is what was conceded without authority."

Buchanan's right forefinger moved, once, against the table's edge. "If I may — the commissioners who sit opposite him are not the same commissioners who would sit opposite any successor. The relationships he has cultivated, the channels of confidence he has established with Peña y Peña's men — these are not transferable. They are particular to this moment, to—"

"You are arguing that his insubordination is an asset."

"I am arguing that the consequences of recalling him at this juncture require — that is to say, the question of what replaces him is not a simple one, and the interests of this republic—"

"The interests of this republic are served by an envoy who executes his instructions, Mr. Buchanan. Not by one who substitutes his own judgment for the President's." Polk straightened from the table. "If this boundary stands, every Southern senator who voted for this war will demand to know why the administration surrendered the route their constituents require. Mr. Calhoun will have the answer before I can compose it. The Whig press will have it before Calhoun."

The telegraph erupted — a clatter of the stylus, rapid and emphatic, that brought all three men upright. Prewitt crossed the room, bent over the machine, watched the tape emerge.

"Weather report. Fort McHenry."

The apparatus fell silent. The acid smell thickened in the failing light.

"Mr. Buchanan." The voice carried the terrible evenness of a man who has passed beyond anger into the country of decision. "You will draft a communication this evening. He is to cease all negotiations with immediate effect. He is to return to Washington and report to this office. You will make plain — in terms that admit no construction but the one intended — that no treaty, no armistice, no preliminary instrument of any kind bears the authority of this government unless it carries my direct authorisation. His commission is revoked."

A silence. Then Buchanan, with the careful precision of a man entering his dissent into the record while taking care that it should not appear as dissent: "Mr. President, if we recall the only envoy positioned to receive Mexico's surrender at the moment when their capital is about to fall — we may find ourselves in possession of a conquered city and no lawful means of ending the war."

"Then we shall end it on terms this government has authorised. Not on terms invented in the field."

"The courier for Veracruz departs the day after tomorrow. If I am to reach him—"

"You will reach him tonight. The draft will be on my desk before I retire."

Buchanan's forefinger stilled against the table's edge. He looked at the map — at the chalk line, at the valley, at the indemnity figure Prewitt had read aloud — and then he looked at Polk, and whatever calculation he was completing, he completed it without speaking. He inclined his head. The gesture was neither agreement nor submission; it was the acknowledgment of one who recognises a closed door and does not press it.

He gathered his hat from the chair beside him and left without further remark.

The lamp had burned to a low, unsteady flame by the time Polk opened the diary. What light remained pooled across the desk's surface, abandoning the room's corners to a darkness that smelled of tallow smoke and the slow exhalations of old wood warming in the night heat. He drew the book toward him and uncapped the inkwell. Through the open window the air hung motionless — the distant cry of a nightbird, the creak of a sentry's boots on the gravel path below, the faint rot of the canal drifting up from the south. He pressed the heel of his hand against the open page and felt the grain of the paper, the slight give of the binding beneath his palm.

He dipped the pen and began to write.

This day has been one of the most materially consequential of my administration. The dispatches from the field, together with the armistice terms as proposed by the envoy, have made plain what I have long suspected: that the man dispatched by this government to negotiate a treaty has arrogated to himself a discretion in territorial matters which the Constitution reposes exclusively in the President. I have this day directed the Secretary of State to prepare the necessary communication recalling him from his mission.

The nib split. A fine spray of ink scattered across the lower margin. He set the pen down, took up his penknife, and trimmed the point with four precise strokes — the blade catching the lamp's diminished light, the shavings of quill falling onto the blotter. He wiped the pen, dipped it, and held it above the page.

He did not immediately write.

The earlier dispatches returned to him uninvited. Trist wrote well — that could not be denied. The April letter from Puebla had described the Mexican government's internal divisions with an accuracy none of Polk's other sources had approached: the factions named, their finances traced, the commissioners who could bind their principals distinguished from those who could not. The letter had been, in its own terms, a work of genuine intelligence. Trist had understood what Peña y Peña required for ratification. He had understood what Santa Anna's defeat at Contreras had cost the war party. He had understood the precise margin of humiliation within which a Mexican government might survive a negotiated peace.

Polk understood these things now because Trist had explained them to him. And that was the offence — not incompetence but its opposite. A capable man acting beyond his authority was more dangerous than a fool, because a fool could be dismissed and a capable man had to be answered.

He put the pen to the page.

*It is not the competence of the envoy that is in question. It is the principle that the executive power of this republic, in the conduct of its foreign relations, is not divisible. An agent who acts upon his own judgment in place of his instructions does not serve the republic — he supplants it. The boundary terms proposed, conceding the Mesilla Valley and leaving the line south of the Gila, were never authorised by this government and represent not a diplomatic judgment but an

act of constitutional insubordination.*

He wrote without stopping now, the sentences arriving in the cadence he preferred, each one closing behind him like a bolt driven home. He underlined constitutional insubordination with a single stroke. Then he noted — the pettiness of it rising in him like bile, unstoppable — that the handwriting evidenced in the dispatches reviewed through the course of the day was slovenly and unbecoming a representative of this government.

He turned the page.

The recall order will proceed by morning courier. Until it reaches its destination, no agreement reached with the Mexican commissioners can be considered valid.

He set the pen in its tray. He blotted the page, pressing the paper down across every line with a force that left the blotter dimpled. Then he closed the book.

The sealed order lay on Buchanan's desk, ready for the morning courier. In six weeks — perhaps seven, if the roads held and the guerrilleros did not intercept the packet — it would reach the man it was meant to stop.

Polk rose. His knees ached. His abdomen carried the dull residue of the morning's clenching, a low heat that had not fully subsided. He crossed to the window and stood where the night air, such as it was, moved against the sweat on his neck.

Below, the city lay dark except for the watch-lamps along the Avenue and a single lit window in the building opposite — Marcy, he supposed, still assembling the correspondence Polk had demanded, still reckoning what its disclosure would cost him.

The knock came before he had turned from the glass.

Not the soft, anticipatory rap of a servant. This was the knock of a man who had run, who had not paused at the outer door to compose himself, who carried something that could not wait for morning. Polk did not move from the window.

"Enter."

The aide was one of Buchanan's — young, his cravat pulled loose, a leather dispatch wallet held against his chest with both hands as though it might otherwise escape him.

"Mr. President." He crossed the room in four strides and held out the wallet. "From the telegraph office, sir. The operator held it for the Secretary, but the Secretary said — the Secretary said you would want it at once."

Polk took it. The leather was damp from the aide's grip. Inside, a single folded sheet, the ink still carrying the faint chemical smell of the transcription.

He read it once. Then again.

Trist had not waited for instructions. The commissioners had convened that afternoon in the village of Guadalupe Hidalgo. A treaty — terms undisclosed as yet, the telegraph rendering only the barest fact of the thing — had been signed.

The aide stood with his hands at his sides, watching the President's face for whatever it would yield.

Polk yielded nothing. He folded the sheet along its original crease and held it.

"Who else has seen this?"
