The entrance was through a narrow opening in the centre of the rampart; but this was now closed up with heavy stones, that seemed to form one solid work with the rest of the masonry. It was an affair of time to dislodge these huge masses, in such a manner as not to rouse the garrison. The Indian nations, who rarely attacked in the night, were not sufficiently acquainted with the art of war even to provide against surprise by posting sentinels. When the task was accomplished, Juan Pizarro and his gallant troop rode through the gateway, and advanced towards the second parapet. But their movements had not been conducted so secretly as to escape notice, and they now found the interior court swarming with warriors, who- as the Spaniards drew near, let off clouds of missiles that compelled them to come to a halt. Juan Pizarro, aware that no time was to be lost, ordered one half of his corps to dismount, and, putting himself at their head, prepared to make a breach as before in the fortifications. He had been wounded some days previously in the jaw, so that, finding his helmet caused him pain, he rashly dispensed with it, and trusted for protection to his buckler.20 Leading on his men, he encouraged them in the work of demolition, in the face of such a storm of stones, javelins, and arrows, as might have made the stoutest heart shrink from encountering it. The good mail of the Spaniards did not always protect them; but others took the place of such as fell, until a-breach was made, and the cavalry, pouring in, rode down all who opposed them.
