clouds of arrows; while their comrades on the roofs of the houses took more deliberate aim at the combatants in the court-yard. The Mexicans were particularly expert in the use of the sling;4 and the stones which they hurled from their elevated positions on the heads of their enemies did even greater execution than the arrows. They glanced, indeed, from the mail-covered bodies of the cavaliers, and from those who were sheltered under the cotton panoply, or escaupil. But some of the soldiers, especially the veterans of Cortés, and many of their Indian allies, had but slight defences, and suffered greatly under this stony tempest.
The Aztecs, meanwhile, had advanced close under the walls of the intrenchment, their ranks broken and disordered and their limbs mangled by the unintermitting fire of the Christians. But they still pressed on, under the very muzzles of the guns. They endeavored to scale the parapet, which, from its moderate height, was in itself a work of no great difficulty. But the moment they showed their heads above the rampart they were shot down by the unerring marksmen within, or stretched on the ground by a blow of a Tlascalan maquahuitl. Nothing daunted, others soon appeared to take the place of the fallen, and strove by raising themselves on the writhing bodies of their dying comrades, or by fixing their spears in the crevices of the wall, to surmount the barrier. But the attempt proved equally vain.
Defeated here, they tried to effect a breach in the parapet by battering it with heavy pieces of timber. The works were not constructed on those scientific principles by which one part is made to overlook and protect another. The besiegers, therefore, might operate at their pleasure, with but little molestation from the garrison within, whose guns could not be brought into a position to bear on them, and who could mount no part of their own works for their defence without exposing their persons to the missiles of the whole besieging army. The parapet, however, proved too strong for the efforts of the assailants. In their despair, they
