"They should reach our ship in two days ... three at the most ... if they are pushing," Travis said thoughtfully. "It would be a help—if that flyer is a link in any com unit—to destroy it before its crew picks up and relays any report of what happens back there."

Jil-Lee grunted. He was surveying the heights above the pocket in which Menlik and two of the Mongols were piling brush. "There ... there ... and there...." The Apache's chin made three juts. "If the pilot swoops for a quick look, our cross fire will take out his blades."

They held a last conference with Menlik and then climbed to the perches Jil-Lee had selected. Sentries on lookout reported by mirror flash that Tsoay, Deklay, Lupe, and Nolan were now on the move to join the other three Apaches. If and when Manulito's trap closed its jaws on the Reds at the western ship, the news would pass and the Apaches would move out to storm the enemy fort on the prairie. And should they blast any caller the helicopter might carry, Menlik and his riders would accompany them.

There it was, just as Menlik had foretold: The wasp from the open country was flying into the hills. Menlik, on his knees, struck flint to steel, sparking the fire they hoped would draw the pilot to a closer investigation.

The brush caught, and smoke, thick and white, came first in separate puffs and then gathered into a murky pillar to form a signal no one could overlook. In Travis' hands the grip of the gun was slippery. He rested the end of the barrel on the rock, curbing his rising tension as best he could.

To escape any caller on the flyer, the Tatars had remained in the valley below the Apaches' lookout. And as the helicopter circled in, Travis sighted two men in its cockpit, one wearing a helmet identical to the one they had seen on the Red hunter days ago. The Reds' long undisputed sway over the Mongol forces would make them overconfident. Travis thought that even if they sighted one of the waiting Apaches, they would not take warning until too late.

Menlik's bush fire was performing well and the flyer was heading straight for it. The machine buzzed the smoke once, too high for the Apaches to trust raying its blades. Then the pilot came back in a lower sweep which carried him only yards above the smoldering brush, on a level with the snipers.

Travis pressed the button on the barrel, his target the fast-whirling blades. Momentum carried the helicopter on, but at least one of the marksmen, if not all three, had scored. The machine plowed through the smoke to crack up beyond.

Was their caller working, bringing in the Mongols to aid the Reds trapped in the wreck?

Travis watched Menlik make his way toward the machine, reach the cracked cover of the cockpit. But in the shaman's hand was a bare blade on which the sun glinted. The Mongol wrenched open the sprung door, thrust inward with the tulwar, and the howl of triumph he voiced was as worldless and wild as a wolf's.
