Numerous bands of Mexicans, half from Mexico and half from the United States, committed depredations, stole property and killed Americans all along the river to Brownsville. This so-called Garza war kept my troops busy marching, and in the difficult effort to punish them we lost a number of men.
Another disturbing element between the two countries was the formation of large islands in the river. The shifting stream produced these "bancos," as they were called, which, when two or three hundred acres in extent, were claimed by the more excitable and lawless of both sides. They were used as a refuge by smugglers and other criminals denying the jurisdiction of both countries.
One of the bancos, Banco de Vela, was used by an American as a pasturage for about three thousand sheep. The Mexican customs authorities put the herders in jail and took the sheep into Mexico, as confiscated under their revenue laws. In retaliation the sheriff of the Texan county put the Mexicans found on the banco in jail.
Colonel Minero, commanding the 4th Mexican Cavalry, at the city of Reynosa, was opposite Banco de Vela. My regiment, the 3d U. S. Cavalry, was drawn up on one side to prevent further arrests and probable conflicts between the contending parties. This situation caused the organization of the Boundary Commission, of which I was later a member. (Text, 281.)
Ordered to relieve the 2d Cavalry under Colonel Wade, my regiment arrived at Fort Reno, June 24, 1893. I had always stated that if I ever became colonel and the authorities gave me an insignificant command of but one or two companies, the band and the laundresses, I would apply for retirement. A few days after reaching Fort Reno, one company was detached, leaving me but two companies of my own regiment. I wrote General Miles, commanding the department, my official and personal friend, that as regulations held me responsible for the efficiency and discipline of my regiment, I would prefer to take advantage of my right to retire on thirty years, unless I could be furnished with at least half of the regiment. For that purpose I asked six months' leave.
The general replied that he would, if it were possible, furnish me the half or the whole of my regiment, but the conditions were such that he could not. When I applied, he recommended my leave. Nannie, with Constance, had preceded me to Worcester, where I went to make arrangements to retire and devote my attention to my cartridge belt factory there.
But General Gresham, who knew of my familiarity with the banco troubles, told me the President had decided to appoint a Boundary Commissioner, and offered me the post. Supposing that it would only last a year or two, and knowing that I was well acquainted with the people of both sides and the nature of the questions involved, I decided to accept. Then it was discovered that I could not lawfully do so, unless I resigned my army commission, as no one could hold two government positions. The Secretary told me he was so anxious I should take the place, he would procure a resolution from Congress authorizing me to accept it as a colonel of cavalry, with pay and allowances as such, which he did. I entered upon this duty, not expecting it to last long, or to become a general.
As I look back over my military career I am impressed with the changes which time has wrought in the size of the military establishment. When I was made a colonel, there were but seventy-two colonels in the line, although forty-five States, represented by ninety senators, were then in the Union.
When I was made a general officer there were but nine general officers in the line of the army; while at that time the President of the United States had eight cabinet officers.
