Knowing how necessary it was to surprise them he shouted to his companions to charge at once.

Not doubting he would be followed, he dashed ahead with his horse on a dead run, but looking over his shoulder when he had gone part way, he saw to his consternation he was alone.
Angered and impatient, he rode back to learn what it meant.

The chief guide had directed the men to wait as there was no doubt the Apaches desired to hold a parley.

It meant the next moment in the shape of a bullet from the Indians which struck the leader in the breast and rendered him senseless.

As soon as he recovered, he ordered his men to make the attack and leave him to himself.
He was obeyed, but the delay was fatal.
