Fort Brown, Texas, March 18, 1860.
I received information a few days since from General Garcia that Cortinas had made his appearance again at the Mera with about 40 men. I immediately gave notice to the troops on the line. Captain Stoneman suggested a plan to attack him, which was approved. They unfortunately came in collision with a force General Garcia had sent up to co-operate with them.
Both Captain Stoneman and Captain Ford are pretty well convinced that Cortinas was at the Mera that night, but got away. A boy and some women said that he was in the rancho. Another man says positively that Cortinas was in the Mera the morning before. It is very difficult to arrive at the truth.
I have no doubt but that the authorities of Matamoras are sincere in their efforts to arrest him, but I more than doubt the fidelity of their troops. Cortinas or some of his friends have recently been in the interior, and it is generally believed that he is in communication with the Miramon party. Should this party gain the ascendancy in Matamoras, I doubt whether the force at my disposal would be sufficient to protect this frontier.
I am, sir, very respectfully, your obedient servant,
Major 1st Infantry, Com’g Brownsville Expedition.

We had therefore no time to lose, but immediately charged into the place on three sides, the back being a dense chaparral; shots were exchanged before we found that our opponents claimed to be national guards, and we regret to say that one Mexican soldier and one woman were wounded, the latter mortally, while she was trying to close a door from which an officer was firing at the cavalry as they were passing the house; none of our command was wounded, but the operation has cost us four horses. While taking breakfast within a few hundred yards of the rancho, a command numbering 150 or more of foot and mounted men, arrived, and the commander thereof asked for a
conference.
We informed him that we were after Cortinas, and that we had been informed officially that he was at the Mera with forty men or more, and he informed us that he was on the same duty; yet he, as well as all his officers, disclaimed all knowledge of his whereabouts. From conversation with him and others we learned that he had been watching us during the past day and night, and this, together with the conduct of the troops, led us to believe that he intended to attack us, but found our united force too strong for him to venture an attack upon us.
During the interview he requested that we should remain where we were until he could send to Matamoras and get a reply, which we declined doing, and informed him that in the pursuit of our object we should act according to the circumstances which might arise from time to time. We shall remain on the Mexican side of the Rio Grande until the passage down of the steamer, or until our presence here is no longer required, unless we receive orders to the contrary.
We are, very respectfully, your obedient servants,
Captain 2a Cavalry, Comd’g Regular Force.

A dispatch in Difficulties on Southwestern Border, House Documents, Volume 126; Volume 128, United States House of Representatives, U.S. Government Printing Office, 1860
During the 12 years following the Mexican-American War there were present on the frontiers of Texas and Mexico many factors that tended to create disturbances. The topography of the country, the sparsity and general character of its population, the lack of an extradition treaty and of sufficient national authority, wild Indians of uncertain abode, the Mexican tariff system, all caused friction and gave encouragement to lawlessness which not only retarded the development of the region but often threatened to interrupt friendly relations between the two republics.
