Ross's horse was pulled up as Foscar drove his heel into the ribs of his own mount, sending it at a brisker pace toward the neck of the valley. There was a blot of blue there--more than one of the aliens were waiting. Ross caught his lip between his teeth and bit down on it hard. He had stood up to the Reds, to Foscar's tribesmen, but he shrank from meeting those strangers with an odd fear that the worst the men of his own species could do would be but a pale shadow to the treatment he might meet at their hands. Foscar was now a toy man astride a toy horse. He halted his galloping mount to sit facing the handful of strangers. Ross counted four of them. They seemed to be talking, though there was still a good distance separating the mounted man and the blue suits. Minutes passed before Foscar's arm raised in a wave to summon the party guarding Ross. Ennar kicked his horse to a trot, towing Ross's mount behind, the other two men thudding along more discreetly. Ross noted that they were both armed with spears which they carried to the fore as they rode. They were perhaps three quarters of the way to join Foscar, and Ross could see plainly the bald heads of the aliens as their faces turned in his direction. Then the strangers struck. One of them raised a weapon shaped similarly to the automatic Ross knew, except that it was longer in the barrel. Ross did not know why he cried out, except that Foscar had only an ax and dagger which were both still sheathed at his belt. The chief sat very still, and then his horse gave a swift sidewise swerve as if in fright. Foscar collapsed, limp, bonelessly, to the trodden turf, to lie unmoving face down. Ennar whooped, a cry combining defiance and despair in one. He reined up with violence enough to set his horse rearing. Then, dropping his hold on the leading rope of Ross's mount, he whirled and set off in a wild dash for the trees to the left. A spear lanced across Ross's shoulder, ripping at the blue fabric, but his horse whirled to follow the other, taking him out of danger of a second thrust. Having lost his opportunity, the man who had wielded the spear dashed by at Ennar's back. Ross clung to the mane with both hands. His greatest fear was that he might slip from the saddle pad and since he was tied by his feet, lie unprotected and helpless under those dashing hoofs. Somehow he managed to cling to the horse's neck, his face lashed by the rough mane while the animal pounded on. Had Ross been able to grasp the dangling nose rope, he might have had a faint chance of controlling that run, but as it was he could only hold fast and hope.
