The bugle notes broke upon the ears of the redskins just in time to deprive them of their prey, for, wheeling to one side of the retreat, they drove on at full speed, for they knew that United States cavalry was upon them and in large force.

“After them, men!” shouted Buffalo Bill, and with Captain Keyes by his side, and nearly a hundred troopers following, they rode hot on the heels of the flying redskins.

It was a complete surprise, of the kind that causes a stampede, and the Indians only sought to escape their pursuers until they reached a place where they could rally and ambush their foes.

But Captain Keyes was too good a soldier to be caught in a trap, with tired-out horses and men, and he called a halt when his command drew near a heavily timbered hill.

“Halt here, men, and let them think this is all the force, while Cody, you go back, meet the other men and flank yonder ridge with them, ordering a courier to go to the reserve and fetch them, with the gun, to your aid with all speed.”

It was almost daylight now, and the tired men rested where they were in line of battle, while Buffalo Bill rode back, checking the troopers still coming up and ordering them to keep out of sight in the timber, while he went to the retreat of those who had been rescued in the nick of time.
