The next morning silence reigned over the city. Not a Mexican was to be seen anywhere near the palace, within which the Spaniards were virtually prisoners. Cortez hoped, however, that Cuitlahua would soon persuade the people to return to their usual habits, and to open the markets for provisions; but in any case, he felt so confident of his power to overawe the city, that he sent off a messenger with dispatches to the coast, saying that he had arrived safely, and should soon overcome all opposition.

In half an hour, however, the messenger returned at a gallop, wounded in a score of places. He reported that the city was up in arms, the drawbridges were raised, and the Mexicans were marching towards the palace. Scarcely had he arrived, when the sentinels on the towers shouted that masses of men were approaching, by all the streets leading to the palace; and immediately afterwards the terraces and flat roofs of the houses near were darkened by throngs of natives, shouting and brandishing their weapons.

The trumpet instantly sounded to arms, and so strict was the discipline that prevailed that, in an incredibly short time, every soldier was at his post. The position was capable of being defended against a very numerous enemy, unprovided with artillery; for the wall round the great one-storied building, though low, was strong; and the turrets, placed at intervals upon it, enabled the defenders to command its face, and to pour missiles upon any who might be bold enough to endeavor to effect a breach, by undermining it with crowbars and levers. The garrison, too, were sufficient for its defense; for there were not only some twelve hundred Spaniards, but the eight thousand Tlascalan allies.

The Aztecs rushed forward, with the shrill whistle used as a battle cry by the people of Anahuac; and, as they advanced, poured a rain of missiles of all kinds upon the palace, to which were added those shot from the terraces and flat roofs.

The Spaniards had pierced the walls with embrasures for their cannon, and these commanded all the avenues. The gunners waited until the columns were close at hand, and then their terrible discharge swept lanes through the crowded masses in the streets. For a moment the Mexicans paused, paralyzed by the terrible slaughter; and then, rallying, rushed forward again. Three times the cannon were discharged into their midst; but though broken and disordered, they still pressed on until they swept up to the very foot of the walls, pouring in a hail of arrows.

They were well seconded by those on the housetops who, from their elevated position, were on a level with the Spaniards; and whose missiles, arrows, javelins, and stones thrown with great force from slings, galled the defenders greatly, and wounded great numbers of them.

In vain did the Aztecs strive to climb the walls. These were of no great height but, as they showed their heads above the parapet, they were shot down by the Spanish arquebus men, or struck backwards by the weapons of the Tlascalans. Failing to scale the walls, they tried to batter down the parapet with heavy pieces of timber. But the stonework was too strong, and they then shot burning arrows into the palace, and hurled blazing torches over the wall.

The palace itself was of stone, but some of the exterior works which had been constructed were of wood, and these were soon on fire. The defenders had no water with which to extinguish the flames and, at the point where the new works joined the wall, the fire was so fierce that they were afraid it would spread to the palace; and, to extinguish it, were forced to adopt the desperate expedient of overthrowing the wall upon the burning mass. The breach thus made was guarded by a battery of heavy guns and a party of arquebusiers, and these repelled every attempt of the Mexicans to take advantage of the breach which had been thus formed.
