And so it proved. The Pawnees reported a skirmish with the Sioux, in which a few of the latter had been killed.

The next day the regiment set forth upon the trail of the Sioux. They traveled rapidly, and plainly gained ground.

At every camp the print of a woman's shoe was noted among the tracks of moccasined feet. The band evidently had a white captive in tow, and General Carr, selecting the best horses, ordered a forced march, the wagon-trains to follow as rapidly as possible. Will, with six Pawnees, was to go ahead and locate the hostiles, and send back word, so that a plan of attack might be arranged before the Indian village was reached.

This village the scouts discovered among the sand-hills at Summit Springs, a few miles from the South Platte River; and while the Pawnees remained to watch, Will returned to General Carr with the news.

There was suppressed excitement all along the line, as officers and men prepared for what promised to be a lively scrimmage. The troops moved forward by a circuitous route, and reached a hill overlooking the hostile camp without their presence being dreamed of by the red men.

The bugler was ordered to sound the charge, but he was trembling with excitement, and unable to blow a note.

"Sound the charge, man!" ordered General Carr a second time; but the unhappy wight could scarcely hold his horn, much less blow it. Quartermaster Hays snatched the instrument from the flustered man's hands, and as the call rang out loud and clear the troops rushed to the attack.

Taken wholly by surprise, the Indian village went to pieces in a twinkling. A few of the Sioux mounted and rode forward to repel the assault, but they turned back in half a minute, while those that were not mounted scattered for the foothills hard by. The cavalry swept through the village like a prairie fire, and pursued the flying Indians until darkness put an end to the chase.

By the next morning the bugler had grown calm enough to sound "Boots and Saddles!" and General Carr split his force into companies, as it was discovered that the Indians had divided. Each company was to follow a separate trail.

Will made one of a band of two hundred, and for two days they dogged the red man's footsteps. At sunrise of the third day the trail ran into another, showing that the Sioux had reunited their forces. This was serious for the little company of regulars, but they went ahead, eager for a meeting with the savages.

They had not long to wait. The sun was scarcely an hour high when some six hundred Sioux were espied riding in close ranks along the bank of the Platte. The Indians discovered the troops at the same moment, and at once gave battle. The Indian is not a coward, though he frequently declines combat if the odds are not largely in his favor.

In this engagement the Sioux outnumbered the soldiers three to one, and the latter fell back slowly until they reached a ravine. Here they tethered their horses and waited the course of Indian events, which, as usual, came in circular form. The Sioux surrounded the regulars, and finding them comparatively few in number, made a gallant charge.

But bows and arrows are futile against powder and ball, and the warriors reeled back from a scathing fire, leaving a score of their number dead.

Another charge, another repulse; and then a council of war. This lasted an hour, and evidently evolved a brilliant stratagem, for the Sioux divided into two bands, and while one made a show of withdrawing, the other circled around and around the position where the soldiers lay.

At a point in this revolving belt of redskins rode a well-mounted, handsome warrior, plainly a chief. It had been Will's experience that to lay low a chief was half the battle when fighting Indians, but this particular mogul kept just out of rifle-shot. There are, however, as many ways of killing an Indian as of killing a cat; so Will crawled on hands and knees along the ravine to a point which he thought would be within range of the chief when next he swung around the circle.

The calculation was close enough, and when the warrior came loping along, slacking his pace to cross the ravine, Will rose and fired.

It was a good four hundred yards, but the warrior pitched from his seat, and his pony ran down the ravine into the ranks of the soldiers, who were so elated over the success of the shot that they voted the animal to Will as a trophy.

The fallen warrior was Tall Bull, one of the ablest chiefs the Sioux ever had. His death so disheartened his braves that they at once retreated.

A union of General Carr's scattered forces followed, and a few days later an engagement took place in which three hundred warriors and a large number of ponies were captured. Some white captives were released, and several hundred squaws made prisoners.

Among these latter was the amiable widow of Tall Bull, who, far from cherishing animosity against Will as the slayer of her spouse, took pride in the fact that he had fallen under the fire of so great a warrior as "Pahaska," Long-haired Chief, by which name our scout was known among the Indians.
