The officer's face went poker-expressionless. He looked at the lone figure, dressed in the garb of the Tuareg, even to the turban-veil which covers all but the eyes of these notorious Apaches of the Sahara.

"This is no affair of yours," the lieutenant said. "Who are you?"

Homer Crawford said very clearly, "Sahara Division, African Development Project, Reunited Nations. You're far out of your own territory, lieutenant. I'll have to report you, and also to demand that you turn and go back to your origin."

The lieutenant flicked his hand, and the trooper behind the Brenn gun sighted the weapon and tightened his trigger finger.

Crawford dropped to the ground and rolled desperately for a slight depression that would provide cover. He could have saved himself the resultant bruises and scratches. Before the Brenn gun spoke even once, there was a Götterdammerung of sound and the three occupants of the jeep, driver, lieutenant and gunner were swept from the vehicle in a nauseating obscenity of exploding flesh, uniform cloth, blood and bone.

To the side, Abe Bakr behind his thorn bush and rock vantage point turned the barrel of his Tommy-Noiseless to the first of the half tracks. Already Arab Union troopers were debouching from them, some firing at random and at unseen targets. However, the so-called Enaden smiths were well concealed, their weapons silenced except for the explosion of the tiny shells upon reaching their target.

It wasn't much of a fight. The recoilless automatic rifle manned by Elmer Allen and Kenny Ballalou swept the wadi, swept it of life, at least, but hardly swept it clean. What few individuals were left, in what little shelter was to be found in the dry river's bottom, were picked off easily, if not neatly by the high velocity automatics in the hands of Abe Bakr and Bey-ag-Akhamouk.

Afterwards, the five of them, standing at the side of the wadi, stared down at their work.

Elmer Allen muttered a bitter four-letter obscenity. He had once headed a pacifist group at the University in Kingston, Jamaica. Now his teeth were bared, as they always were when he went into action. He hated it.
