The camp at La Pena was on sandy ground, unpleasant for men and animals, and by my advice it was moved to La Pendencia, not far from Lake Espantosa.  Before removal from our old location, however, early one bright morning Frankman and I started on one of our customary expeditions, going down La Pena Creek to a small creek, at the head of which we had established a hunting rendezvous.  After proceeding along the stream for three or four miles we saw a column of smoke on the prairie, and supposing it arose from a camp of Mexican rancheros catching wild horses or wild cattle, and even wild mules, which were very numerous in that section of country along the Nueces River, we thought we would join the party and see how much success they were having, and observe the methods employed in this laborious and sometimes dangerous vocation.  With this object in view, we continued on until we found it necessary to cross to the other side of the creek to reach the point indicated by the smoke.  Just before reaching the crossing I discovered moccasin tracks near the water’s edge, and realizing in an instant that the camp we were approaching might possibly be one of hostile Indians—­all Indians in that country at that time were hostile—­Frankman and I backed out silently, and made eager strides for La Pena, where we had scarcely arrived when Captain M. E. Van Buren, of the Mounted Rifle regiment, came in with a small command, and reported that he was out in pursuit of a band of Comanche Indians, which had been committing depredations up about Fort Clark, but that he had lost the trail.  I immediately informed him of what had occurred to me during the morning, and that I could put him on the trail of the Indians he was desirous of punishing.

We hurriedly supplied with rations his small command of thirteen, men, and I then conducted him to the point where I had seen the smoke, and there we found signs indicating it to be the recently abandoned camp of the Indians he was pursuing, and we also noticed that prairie rats had formed the principal article of diet at the meal they had just completed.  As they had gone, I could do no more than put him on the trail made in their departure, which was well marked; for Indians, when in small parties, and unless pressed, usually follow each other in single file.  Captain Van Buren followed the trail by Fort Ewell, and well down toward Corpus Christi, day and night, until the Indians, exhausted and used up, halted, on an open plain, unsaddled their horses, mounted bareback, and offered battle.  Their number was double that of Van Buren’s detachment, but he attacked them fearlessly, and in the fight was mortally wounded by an arrow which entered his body in front, just above the sword belt, and came through the belt behind.  The principal chief of the Indians was killed, and the rest fled.  Captain Van Buren’s men carried him to Corpus Christi, where in a few days he died.
