Food was now cooked, and, after eating, the three relapsed into silence. Presently Middleton, also, joined them, and told them that very thorough preparations had been made to guard against a surprise. Sentinels on horseback were already far out on the plain, riding a watchful round which would be continued all through the night. "It is easy to guard against surprise on that side," said Middleton, "but snipers may creep down the river bank in the timber. We must keep our best watch there." "I’ll go on duty," said Philip promptly. "Not yet," replied Middleton. "You may be needed late in the night, in which case we’ll call on you, but our most experienced borderers don’t think the Comanches will come back." "You can never trust them," said Arenberg earnestly. "We don’t mean to," said Middleton. "Now, Phil, I’d advise you to wrap yourself in your blanket and go to sleep. On a campaign it’s always advisable to sleep when you’re off duty, because you never know when you will get the chance again." It seemed to Phil that it was impossible to sleep, after so much excitement and danger, but he knew that Middleton was speaking wise words, and he resolved to try. There were yet hours of daylight, but, putting his blanket beneath him, he lay before one of the fires with his arm under his head and closed his eyes. He would open them now and then to see the yellow flames, the figures of the men moving back and forth, and the circle of wagons beyond. He could not make himself feel sleepy, but he knew that his nerves were relaxing. Physically he felt a soothing languor, and with it came a mental satisfaction. He had helped to win his first battle, and, like the older and seasoned men around him, the victory encouraged him to bid further defiance to the Comanches or anything else that threatened. [Illustration: "Putting his blanket beneath him, he lay before one of the fires"] These reflections were so grateful that he found himself able to keep his eyes shut longer. It was not so much of an effort to pull the eyelids down, and when, at intervals steadily growing more distant, he opened his eyes, it was to find the fires and figures of the men becoming dim, while the circling line of the wagons beyond was quite lost. At last the eyelids stayed down of their own accord, and he floated away into a sleep that was deep, sweet, and refreshing.
