"The Mexican army retreated in great haste southward after Buena Vista, in order to meet Scott, who was advancing on Mexico by the way of Vera Cruz. That left the country comparatively clear for us, and we came through the mountains, until we saw the Castle of Montevideo. When we saw it, we believed still more strongly that this was the place, but we knew that the biggest part of our work was before us. We would have to spy, and spy, and keep on spying before we could act. Any mule driver or sheepherder might carry news of us, and we must have a secure hiding-place as a basis. After a long search we found this cabin, which I don’t think had been occupied for several years. We soon fixed it up so it was comfortable, as you can now see. There’s a little spring at the west edge of the cove, and on the other side of the ridge there’s a little valley with water and grass, but with walls so steep that a horse won’t climb ’em unless he’s led. Our horses are there now, having perhaps the best time of their lives. "When we were located, good and snug, we began to spy. I believed after we met the woman at the well that fortune was favoring us. Arenberg here talked a lot about the spirits of the forest and the stream, some old heathen mythology of his, to which Bill and I didn’t pay any attention. But anyway, we had luck. We scouted about the castle for weeks, but we didn’t learn a thing, except that de Armijo was now governor there. We could find no more trace of you than if you had been on the moon. "At last our lucky day came. We ran squarely upon a good-looking young Mexican, a vaquero. There wasn’t time for us to get away or for him to get away. So we, being the more numerous, seized him. I suppose he thought he was going to be killed at once, as we were Americans, looking pretty tough from exposure and hardships, and so to make a play on our good feelings--Bill Breakstone could understand his Spanish--he said that once he’d tried to help a Gringo, a prisoner, in the great castle in the valley. He said he’d carried a letter from him, asking for help, and that the prisoner was not much more than a boy, taken in a raid from Texas three years ago.
