It was a tough climb in a country where white man apparently had never been before. Gruard and Big Bat did not slacken. The mountains opposed with timber and rock and precipices. All the file gasped; the air was heavy with thunderstorms; overcoats, blouses, everything was thrown aside, except the rifles and the ammunition. The Indians might follow, and might not; but distance was the only safety. The two scouts led without another stop until midnight; then the little company camped amidst the rocks on the very top of a peak. A terrific storm of wind and hail swept over them, so that the falling trees sounded like the crashes of artillery. The temperature almost reached freezing; yet this was no time for complaining. They might have been lying, colder still, among the horses. At first daylight they stumbled on. Gruard and Big Bat saw no rest until within touch of General Crook. The course turned southward, along the crests of the mighty range. They arrived at a canyon so steep that the tired troopers could not clamber down into it. Frank found a sort of a trail by way of a valley, to a crossing of the river at the canyon's bottom; and they needs must hustle madly, to cross and get out before any Indians discovered them in the pocket. The main camp was now twenty-five miles south-east, Gruard thought. The plains were in sight through the gaps; but there would likely be Indians down on those plains. Gruard and Big Bat guided up the opposite side of the canyon. They had to cling like squirrels, following a sheep trail not more than a foot wide, five hundred feet above the stream, and two hundred feet below the rim. But they got out. Gruard swung more eastward, toward the foothills. Beyond the foothills lay the camp of the Crook column. Presently the men were gasping for water. Everybody was pinched with hunger, for there had been nothing to eat and nothing to drink, since they had retreated just in time from the net. It was decided to venture into a valley of the foothills, and find water. They went slipping and sliding down the slope, carpeted with the dried pine needles, and treacherous with loose gravel, and drank in haste. But Frank was still suspicious. His senses were keen. He instantly led them back into the first belt of timber, above; and on a sudden, with a hiss of warning, he flung himself flat. Down they all sprawled. Just below, wellnigh at the very spot they had left, there were more Indians: Sioux! The Sioux were riding, arrayed for war, in open order, like scouts for a larger party behind. If they struck the trail to the water and back, that would mean another fight. It seemed horrible to be cut off, again, when so near help; the location of the General Crook camp was plain in view, off there twenty miles to the east. But the brave soldiers had grown too desperate to care. They were tired out, and determined to sell their lives dearly. Lieutenant Sibley motioned.
