The cross-bowmen fell back, and between their opening lines the pikemen advanced. These were largely mercenaries, and their masters had no compunction about sacrificing them. They were intended to mask the advance of the knights until the latter were within smiting distance. So while the arbalesters plied their bolts from either flank at long range, the pikemen marched into the teeth of the blast from above, and behind them the knights came on. When the pikemen began to falter beneath the savage hail of death that whistled down the slopes among them, a trumpet blew, their companies divided to right and left, and through them the mailed knights thundered. They ran full into a cloud of stinging death. The clothyard shafts found every crevice in their armor and the housings of the steeds. Horses scrambling up the grassy terraces reared and plunged backward, bearing their riders with them. Steel-clad forms littered the slopes. The charge wavered and ebbed back. Back down in the valley Amalric reformed his ranks. Tarascus was fighting with drawn sword under the scarlet dragon, but it was the baron of Tor who commanded that day. Amalric swore as he glanced at the forest of lance-tips visible above and beyond the head-pieces of the Gundermen. He had hoped his retirement would draw the knights out in a charge down the slopes after him, to be raked from either flank by his bowmen and swamped by the numbers of his horsemen. But they had not moved. Camp-servants brought skins of water from the river. Knights doffed their helmets and drenched their sweating heads. The wounded on the slopes screamed vainly for water. In the upper valley, springs supplied the defenders. They did not thirst that long, hot spring day. On the King's Altar, beside the ancient, carven stone, Xaltotun watched the steel tide ebb and flow. On came the knights, with waving plumes and dipping lances. Through a whistling cloud of arrows they plowed to break like a thundering wave on the bristling wall of spears and shields. Axes rose and fell above the plumed helmets, spears thrust upward, bringing down horses and riders. The pride of the Gundermen was no less fierce than that of the knights. They were not spear-fodder, to be sacrificed for the glory of better men. They were the finest infantry in the world, with a tradition that made their morale unshakable. The kings of Aquilonia had long learned the worth of unbreakable infantry. They held their formation unshaken; over their gleaming ranks flowed the great lion banner, and at the tip of the wedge a giant figure in black armor roared and smote like a hurricane, with a dripping ax that split steel and bone alike.
