The swift tide of battle had swept on ahead. Near by a large, officers’ tent reared high its peak. Strangely it had survived the fierce struggle, which, but a few minutes before, had raged round it. To this tent Robert carried Taggert’s body, and placed it softly upon a cot inside. Choking back a lump in his throat, he drew a cover up over the cot and turned away. A bright blue sash caught his eye--one of the rare, brilliant-hued bits of apparel which only the most well-to-do Martians can afford because of the scarcity of minerals for dyes. This he tied conspicuously on the outside of the tent to identify it. With these precautions for later recovery of Taggert’s body, Robert dashed on after the receding line of battle. So hot was the chase and so overwhelming the enemy’s rout, that he had difficulty in gaining the front again. Once more in the front rank he fought furiously, for to his original grievance was now added that of the death of a pal. The resistance of the enemy’s center was completely broken. Its officers no longer had any control over it. Whole companies surrendered rather than be slaughtered. Suddenly, however, the headlong retreat of the enemy was checked. Those in the rear still scattered in consternation, or abjectly surrendered, but ahead there was a confusion and congestion--some obstacle against which the retreat floundered, swirled--and finally rallied. * * * * * Once more Robert found himself in the thick of the fray. Somehow, unaccountably, the enemy’s retreat had been halted. Those in contact with what had been the rear of the retreat, were now actually on the aggressive, fighting like rats, with their backs to a wall. Goaded by the thought of Zola’s danger, Robert fought furiously. His gun he had discarded in lieu of a saber, which he now wielded with terrible destruction. His strength, superior to that of the slightly smaller-statured Martians, was augmented by his passion to destroy, to kill, until he should reach the very heart of this resistance which was keeping him from _her_. His very fierceness was a protection, his whirlwind attack striking terror into the hearts of the opposing Martians near him. His followers, too, inspired by his example, fought with great vigor. Like the head of a wedge they hewed their way steadily into the enemy’s ranks. Once more their opponents were routed. Like chaff they were swept back, leaving but the core of their temporary resistance--a small knot of picked men round whom they rallied briefly though bravely. Against this group Robert charged with his followers. A terrific struggle ensued. By their uniforms Robert knew the stubborn group to be the emperor’s picked guardsmen. His heart leaped with fierce exultation as he realized that he was probably about to face the crafty, deceitful ruler. It was at this juncture that Kharnov himself appeared suddenly from out a sumptuous tent!
