The dry expanse of prairie where the camp lay, sloped gradually up to the eastward, terminating in a ridge at a distance of about a mile from the camp. Over the crest of this ridge a throng of Sioux warriors was now galloping, much as they had come over that other ridge at the opening of the battle of Tahkahokuty. The emigrant camp lay nearest to them, and here a great confusion and panic immediately arose, and women and children began to emerge from the corral and run toward the military camp, shrieking and calling piteously for help. Without waiting for orders scores of soldiers seized their weapons and rushed out across the prairie toward the fugitives, many of whom, as soon as they were within the lines, fell to the ground exhausted or weeping hysterically. The soldiers, once started, continued their advance on the enemy, the swiftest runners distancing the rest. The Indians halted and fired, then seeing that their antagonists were not checked, began sullenly to retire, not even hastening much from the shells of the cannon, which had opened along the eastern edge of the camp. So the retreat and pursuit continued to the crest of the ridge, where the Indians went out of sight into the Bad Lands just beyond.
Al and Wallace, who had run out at the first alarm, presently found themselves, in company with one of the Sioux guides and a couple of soldiers of the Sixth Iowa, on the edge of the ridge with a deep, narrow valley before them, bounded on its farther side by four hillocks, or small buttes, shaped like sugar loaves and each separated from the next by crooked gullies, washed deep by rains. At the left end of this series of buttes lay a long, open space, entirely bare of vegetation, apparently extending around behind them. Not an Indian was in sight, but Wallace suggested,
"I believe some of the redskins are hiding behind those buttes. Let's surprise them. I'll tell you what we can do. You fellows," he addressed the two cavalrymen, "stay here and the rest of us will go back a little way and then sneak around and down across that open space and get in behind the flank of the buttes. If there are any Indians there, we can shoot them before they can get away."
"But there may be a lot of them," objected one of the troopers, "and they'll clean you out."
"No," declared Wallace, with conviction. "It's only a little way across, and if there are too many of them we can run back while you cover us with your fire. Besides, lots of the boys are near by."
This was true; a number of soldiers were still a short distance back on the plateau.
"What do you think of it?" asked Al, turning to the Sioux guide, who happened to be one who could speak English, as well as his own tongue.
"Good," said the Indian. "I go."
"Come on, then," urged Wallace, who seemed determined to have an adventure if possible.
Followed by Al and the guide he walked back across the prairie until the ridge hid them from view of any watchers who might be on the buttes. The two troopers, meanwhile, lay down on the edge of the ridge to wait developments. As soon as they were out of sight of the buttes, the boys turned north and ran for some distance, then swinging east again regained the edge of the ridge opposite the open ground below. Here they could not be seen from any except the northernmost butte and, hastening down the slope, they ran across to the base of this butte and around to its farther side. Looking up, they saw two Indians lying behind the top of the next adjoining eminence, peeping over at the two soldiers across the valley. Simultaneously the three adventurers fired. The head of one of the warriors dropped between his outstretched arms and he lay still without a struggle. His companion sprang to his feet, cast one terrified glance at the unexpected assailants below him and leaped with a few long bounds down the steep slope into the ravine at its base and around the third butte, where he disappeared. Al and Wallace gave a shout, in which the Indian scout joined, and Al ran on in the direction taken by the warrior, followed by Wallace. But the scout hesitated.
