"To arms! to arms!" shouted the captain.  Everybody was instantly on their feet.  I found that he had more arrangements than I had fancied. The Indians had got over the walls of the court-yard, but the gate was so blocked up that they could not open it to get our horses through. Their only outlet was through our house.  The door leading to this was instantly occupied by some of the Mexicans, while others ran their rifles through all the crevices and holes in the walls, and began firing away at the Indians.  They, disappointed in their attempt to carry off our horses, after ham-stringing several of them, leaped back over the walls, exposing themselves as they did so to the rifles of the Mexicans. Several were shot down, but the greater number made their escape.  No one attempted to follow them, however, for there could be no doubt that a large party of them were in the neighbourhood, and that they would very likely renew their attack on us.  They did not disappoint us.  In less than a quarter of an hour the trampling of horses' hoofs was heard, and through the gloom of night a large body of horsemen was seen galloping up through the street of the ruined village.  As they got near, they gave vent to the most unearthly shrieks and cries, intending, undoubtedly, to terrify us.  Captain Driscoll was not, however, totally unprepared for them.  He had stationed the best marksmen of the party behind the walls of the enclosure and at the windows of the house. There was little time, however, to make the arrangements, but each man seemed to know pretty well what he had to do.  Not a shot was fired, not a word was uttered.  The Indians, expecting an easy victory, galloped along the road, flourishing their lances, or holding their rifles ready to fire as soon as any one appeared to fire at.  They got close up to the walls of the house, and there halted, fancying apparently that we had already decamped.  Some got off their horses, to examine the ground for our trail.
