The sharp-shooters returned by nightfall. Soon afterward I established my pickets and outposts well to the front in the jungle, so as to prevent all possibility of surprise. After dark, fires suddenly shot up on the mountain passes far to our right. They all rose together and we could make nothing of them. After a good deal of consultation, we decided they must be some signals to the Spaniards in Santiago, from the troops marching to reinforce them from without--for we were ignorant that the reinforcements had already reached the city, the Cubans being quite unable to prevent the Spanish regulars from marching wherever they wished. While we were thus pondering over the watch-fires and attributing them to Spanish machinations of some sort, it appears that the Spaniards, equally puzzled, were setting them down as an attempt at communication between the insurgents and our army. Both sides were accordingly on the alert, and the Spaniards must have strengthened their outlying parties in the jungle ahead of us, for they suddenly attacked one of our pickets, wounding Crockett seriously. He was brought in by the other troopers. Evidently the Spanish lines felt a little nervous, for this sputter of shooting was immediately followed by a tremendous fire of great guns and rifles from their trenches and batteries. Our men in the trenches responded heavily, and word was sent back, not only to me, but to the commanders in the rear of the regiments along our line, that the Spaniards were attacking. It was imperative to see what was really going on, so I ran up to the trenches and looked out. At night it was far easier to place the Spanish lines than by day, because the flame-spurts shone in the darkness. I could soon tell that there were bodies of Spanish pickets or skirmishers in the jungle-covered valley, between their lines and ours, but that the bulk of the fire came from their trenches and showed not the slightest symptom of advancing; moreover, as is generally the case at night, the fire was almost all high, passing well overhead, with an occasional bullet near by.
