I went first to St. Louis, and there took the steamboat for New Orleans, and when near the mouth of the Red River received word from General Canby that Kirby Smith had surrendered under terms similar to those accorded Lee and Johnston. But the surrender was not carried out in good faith, particularly by the Texas troops, though this I did not learn till some little time afterward when I was informed that they had marched off to the interior of the State in several organized bodies, carrying with them their camp equipage, arms, ammunition, and even some artillery, with the ultimate purpose of going to Mexico. In consequence of this, and also because of the desire of the Government to make a strong showing of force in Texas, I decided to traverse the State with two columns of cavalry, directing one to San Antonio under Merritt, the other to Houston under Custer. Both commands were to start from the Red River —Shreveport and Alexandria—being the respective initial points—and in organizing the columns, to the mounted force already on the Red River were added several regiments of cavalry from the east bank of the Mississippi, and in a singular way one of these fell upon the trail of my old antagonist, General Early. While crossing the river somewhere below Vicksburg some of the men noticed a suspicious looking party being ferried over in a rowboat, behind which two horses were swimming in tow. Chase was given, and the horses, being abandoned by the party, fell into the hands of our troopers, who, however, failed to capture or identify the people in the boat. As subsequently ascertained, the men were companions of Early, who was already across the Mississippi, hidden in the woods, on his way with two or three of these followers to join the Confederates in Texas, not having heard of Kirby Smith's surrender. A week or two later I received a letter from Early describing the affair, and the capture of the horses, for which he claimed pay, on the ground that they were private property, because he had taken them in battle. The letter also said that any further pursuit of Early would be useless, as he "expected to be on the deep blue sea" by the time his communication reached me. The unfortunate man was fleeing from imaginary dangers, however, for striking his trail was purely accidental, and no effort whatever was being made to arrest him personally. Had this been especially desired it might have been accomplished very readily just after Lee's surrender, for it was an open secret that Early was then not far away, pretty badly disabled with rheumatism.
By the time the two columns were ready to set out for San Antonio and Houston, General Frank Herron,—with one division of the Thirteenth Corps, occupied Galveston, and another division under General Fred Steele had gone to Brazos Santiago, to hold Brownsville and the line of the Rio Grande, the object being to prevent, as far as possible, the escaping Confederates from joining Maximilian. With this purpose in view, and not forgetting Grant's conviction that the French invasion of Mexico was linked with the rebellion, I asked for an increase of force to send troops into Texas in fact, to concentrate at available points in the State an army strong enough to move against the invaders of Mexico if occasion demanded. The Fourth and Twenty-fifth army corps being ordered to report to me, accordingly, I sent the Fourth Corps to Victoria and San Antonio, and the bulk of the Twenty-fifth to Brownsville. Then came the feeding and caring for all these troops—a difficult matter—for those at Victoria and San Antonio had to be provisioned overland from Indianola across the "hog-wallow prairie," while the supplies for the forces at Brownsville and along the Rio Grande must come by way of Brazos Santiago, from which point I was obliged to construct, with the labor of the men, a railroad to Clarksville, a distance of about eighteen miles.
The latter part of June I repaired to Brownsville myself to impress the Imperialists, as much as possible, with the idea that we intended hostilities, and took along my chief of scouts—Major Young—and four of his most trusty men, whom I had had sent from Washington. From Brownsville I despatched all these men to important points in northern Mexico, to glean information regarding the movements of the Imperial forces, and also to gather intelligence about the ex-Confederates who had crossed the Rio Grande. On information furnished by these scouts, I caused General Steele to make demonstrations all along the lower Rio Grande, and at the same time demanded the return of certain munitions of war that had been turned over by ex-Confederates to the Imperial General (Mejia) commanding at Matamoras. These demands, backed up as they were by such a formidable show of force created much agitation and demoralization among the Imperial troops, and measures looking to the abandonment of northern Mexico were forthwith adopted by those in authority—a policy that would have resulted in the speedy evacuation of the entire country by Maximilian, had not our Government weakened; contenting itself with a few pieces of the contraband artillery varnished over with the Imperial apologies. A golden opportunity was lost, for we had ample excuse for crossing the boundary, but Mr. Seward being, as I have already stated, unalterably opposed to any act likely to involve us in war, insisted on his course of negotiation with Napoleon.
As the summer wore away, Maximilian, under Mr. Seward's policy, gained in strength till finally all the accessible sections of Mexico were in his possession, and the Republic under President Juarez almost succumbed. Growing impatient at this, in the latter part of September I decided to try again what virtue there might be in a hostile demonstration, and selected the upper Rio Grande for the scene of my attempt. Merritt's cavalry and the Fourth Corps still being at San Antonio, I went to that place and reviewed these troops, and having prepared them with some ostentation for a campaign, of course it was bruited about that we were going to invade Mexico. Then, escorted by a regiment of horse I proceeded hastily to Fort Duncan, on the Rio Grande just opposite the Mexican town of Piedras Negras. Here I opened communication with President Juarez, through one of his staff, taking care not to do this in the dark, and the news, spreading like wildfire, the greatest significance was ascribed to my action, it being reported most positively and with many specific details that I was only awaiting the arrival of the troops, then under marching orders at San Antonio, to cross the Rio Grande in behalf of the Liberal cause.
Ample corroboration of the reports then circulated was found in my inquiries regarding the quantity of forage we could depend upon getting in Mexico, our arrangements for its purchase, and my sending a pontoon train to Brownsville, together with which was cited the renewed activity of the troops along the lower Rio Grande. These reports and demonstrations resulted in alarming the Imperialists so much that they withdrew the French and Austrian soldiers from Matamoras, and practically abandoned the whole of northern Mexico as far down as Monterey, with the exception of Matamoras, where General Mejia continued to hang on with a garrison of renegade Mexicans.
The abandonment of so much territory in northern Mexico encouraged General Escobedo and other Liberal leaders to such a degree that they collected a considerable army of their followers at Comargo, Mier, and other points. At the same time that unknown quantity, Cortinas, suspended his free-booting for the nonce, and stoutly harassing Matamoras, succeeded in keeping its Imperial garrison within the fortifications. Thus countenanced and stimulated, and largely supplied with arms and ammunition, which we left at convenient places on our side of the river to fall into their hands, the Liberals, under General Escobedo—a man of much force of character—were enabled in northern Mexico to place the affairs of the Republic on a substantial basis.
But in the midst of what bade fair to cause a final withdrawal of the foreigners, we were again checked by our Government, as a result of representations of the French Minister at Washington. In October, he wrote to Mr. Seward that the United States troops on the Rio Grande were acting "in exact opposition to the repeated assurances Your Excellency has given me concerning the desire of the Cabinet at Washington to preserve the most strict neutrality in the events now taking place in Mexico," and followed this statement with an emphatic protest against our course. Without any investigation whatever by our State Department, this letter of the French Minister was transmitted to me, accompanied by directions to preserve a strict neutrality; so, of course, we were again debarred from anything like active sympathy.
After this, it required the patience of Job to abide the slow and poky methods of our State Department, and, in truth, it was often very difficult to restrain officers and men from crossing the Rio Grande with hostile purpose. Within the knowledge of my troops, there had gone on formerly the transfer of organized bodies of ex-Confederates to Mexico, in aid of the Imperialists, and at this period it was known that there was in preparation an immigration scheme having in view the colonizing, at Cordova and one or two other places, of all the discontented elements of the defunct Confederacy —Generals Price, Magruder, Maury, and other high personages being promoters of the enterprise, which Maximilian took to readily. He saw in it the possibilities of a staunch support to his throne, and therefore not only sanctioned the project, but encouraged it with large grants of land, inspirited the promoters with titles of nobility, and, in addition, instituted a system of peonage, expecting that the silver hook thus baited would be largely swallowed by the Southern people.
The announcement of the scheme was followed by the appointment of commissioners in each of the Southern States to send out emigrants; but before any were deluded into starting, I made to General Grant a report of what was going on, with the recommendation that measures be taken, through our State Department, looking to the suppression of the colony; but, as usual, nothing could be effected through that channel; so, as an alternative, I published, in April, 1866, by authority of General Grant, an order prohibiting the embarkation from ports in Louisiana and Texas, for ports in Mexico, of any person without a permit from my headquarters. This dampened the ardor of everybody in the Gulf States who had planned to go to Mexico; and although the projectors of the Cordova Colonization Scheme—the name by which it was known—secured a few innocents from other districts, yet this set-back led ultimately to failure.
Among the Liberal leaders along the Rio Grande during this period there sprang up many factional differences from various causes, some personal, others political, and some, I regret to say, from downright moral obliquity—as, for example, those between Cortinas and Canales —who, though generally hostile to the Imperialists, were freebooters enough to take a shy at each other frequently, and now and then even to join forces against Escobedo, unless we prevented them by coaxing or threats. A general who could unite these several factions was therefore greatly needed, and on my return to New Orleans I so telegraphed General Grant, and he, thinking General Caravajal (then in Washington seeking aid for the Republic) would answer the purpose, persuaded him to report to me in New Orleans. Caravajal promptly appeared, but he did not impress me very favorably. He was old and cranky, yet, as he seemed anxious to do his best, I sent him over to Brownsville, with credentials, authorizing him to cross into Mexico, and followed him myself by the next boat. When I arrived in Brownsville, matters in Matamoras had already reached a crisis. General Mejia, feeling keenly the moral support we were giving the Liberals, and hard pressed by the harassing attacks of Cortinas and Canales, had abandoned the place, and Caravajal, because of his credentials from our side, was in command, much to the dissatisfaction of both those chiefs whose differences it was intended he should reconcile.
