The Throg task force struck the Terran Survey camp a few minutes after dawn, without warning, and with a deadly precision which argued that the aliens had fully reconnoitered and prepared that attack. Eye-searing lances of energy lashed back and forth across the base with methodical accuracy. And a single cowering witness, flattened on a ledge in the heights above, knew that when the last of those yellow-red bolts fell, nothing human would be left alive down there. His teeth closed hard upon the thick stuff of the sleeve covering his thin forearm, and in his throat a scream of terror and rage was stillborn. More than caution kept him pinned on that narrow shelf of rock. Watching that holocaust below, Shann Lantee could not force himself to move. The sheer ruthlessness of the Throg move-in left him momentarily weak. To listen to a tale of Throgs in action, and to be an eye-witness to such action, were two vastly different things. He shivered in spite of the warmth of the Survey Corps uniform.
