Again he rode forward. Again the troopers interposed their mounts, and this time their leader cocked his carbine. His attitude was menacing. Billy was close to him. Their ponies were shoulder to shoulder, that of the bandit almost broadside of the trail. Now Billy Byrne was more than passing well acquainted with many of the fundamental principles of sudden brawls. It is safe to say that he had never heard of Van Bibber; but he knew, as well as Van Bibber knew, that it is well to hit first. Without a word and without warning he struck, leaning forward with all the weight of his body behind his blow, and catching the man full beneath the chin he lifted him as neatly from his saddle as though a battering ram had struck him. Simultaneously Bridge and Miguel drew revolvers from their shirts and as Billy wheeled his pony toward the remaining five they opened fire upon them. The battle was short and sweet. One almost escaped but Miguel, who proved to be an excellent revolver shot, brought him down at a hundred yards. He then, with utter disregard for the rules of civilized warfare, dispatched those who were not already dead. “We must let none return to carry false tales to Pesita,” he explained. Even Billy Byrne winced at the ruthlessness of the cold-blooded murders; but he realized the necessity which confronted them though he could not have brought himself to do the things which the Mexican did with such sang-froid and even evident enjoyment. “Now for the others!” cried Miguel, when he had assured himself that each of the six were really quite dead. Spurring after him Billy and Bridge ran their horses over the rough ground at the base of the little hill, and then parallel to the arroyo for a matter of a hundred yards, where they espied two Indians, carbines in hand, standing in evident consternation because of the unexpected fusillade of shots which they had just heard and which they were unable to account for. At the sight of the three the sharpshooters dropped behind cover and fired. Billy's horse stumbled at the first report, caught himself, reared high upon his hind legs and then toppled over, dead. His rider, throwing himself to one side, scrambled to his feet and fired twice at the partially concealed men. Miguel and Bridge rode in rapidly to close quarters, firing as they came. One of the two men Pesita had sent to assassinate his “guests” dropped his gun, clutched at his breast, screamed, and sank back behind a clump of mesquite. The other turned and leaped over the edge of the bank into the arroyo, rolling and tumbling to the bottom in a cloud of dry dust. As he rose to his feet and started on a run up the bed of the dry stream, dodging a zigzag course from one bit of scant cover to another Billy Byrne stepped to the edge of the washout and threw his carbine to his shoulder. His face was flushed, his eyes sparkled, a smile lighted his regular features. “This is the life!” he cried, and pulled the trigger.
