There was no longer any question as to the expediency of evacuating the capital. The only doubt was as to the time of doing so, and the route. The Spanish commander called a council of officers to deliberate on these matters. It was his purpose to retreat on Tlascala, and in that capital to decide according to circumstances on his future operations. After some discussion, they agreed on the causeway of Tlacopan as the avenue by which to leave the city. It would, indeed, take them back by a circuitous route, considerably longer than either of those by which they had approached the capital. But, for that reason, it would be less likely to be guarded, as least suspected; and the causeway itself, being shorter than either of the other entrances, would sooner place the army in comparative security on the mainland.
There was some difference of opinion in respect to the hour of departure. The daytime, it was argued by some, would be preferable, since it would enable them to see the nature and extent of their danger, and to provide against it. Darkness would be much more likely to embarrass their own movements than those of the enemy, who were familiar with the ground. A thousand impediments would occur in the night, which might prevent them acting in concert, or obeying, or even ascertaining, the orders of the commander. But, on the other hand, it was urged that the night presented many obvious advantages in dealing with a foe who rarely carried his hostilities beyond the day. The late active operations of the Spaniards had thrown the Mexicans off their guard, and it was improbable they would anticipate so speedy a departure of their enemies. With celerity and caution, they might succeed, therefore, in making their escape from the town, possibly over the causeway, before their retreat should be discovered; and, could they once get beyond that pass of peril, they felt little apprehension for the rest.
The general had already superintended the construction of a portable bridge to be laid over the open canals in the causeway. This was given in charge to an officer named Magarino, with forty soldiers under his orders, all pledged to defend the bridge to the last extremity. The bridge was to be taken up when the entire army had crossed one of the breaches, and transported to the next. There were three of these openings in the causeway, and most fortunate would it have been for the expedition, if the foresight of the commander had provided the same number of bridges. But the labor would have been great, and the time was short.
At midnight the troops were under arms, in readiness for the march. Mass was performed by Father Olmedo, who invoked the protection of the Almighty through the awful perils of the night. The gates were thrown open, and, on the first of July, 1520, the Spaniards for the last time sallied forth from the walls of the ancient fortress, the scene of so much suffering and such indomitable courage.
The night was cloudy, and a drizzling rain, which fell without intermission, added to the obscurity. The great square before the palace was deserted, as, indeed, it had been since the fall of Montezuma. Steadily, and as noiselessly as possible, the Spaniards held their way along the great street of Tlacopan, which so lately had resounded to the tumult of battle. All was now hushed in silence; and they were only reminded of the past by the occasional presence of some solitary corpse, or a dark heap of the slain, which too plainly told where the strife had been hottest. As they passed along the lanes and alleys which opened into the great street, or looked down the canals, whose polished surface gleamed with a sort of ebon lustre through the obscurity of the night, they easily fancied they discerned the shadowy forms of their foe lurking in ambush, and ready to spring on them. But it was only fancy; and the city slept undisturbed even by the prolonged echoes of the tramp of horses, and the hoarse rumbling of the artillery and baggage trains. At length, a lighter space beyond the dusky line of buildings showed the van of the army that it was emerging on the open causeway. They might well have congratulated themselves on having thus escaped the dangers of assault in the city itself, and that a brief time would place them in comparative safety on the opposite shore. But the Mexicans were not all asleep.
As the Spaniards drew near the spot where the street opened on the causeway, and were preparing to lay the portable bridge across the uncovered breach which now met their eyes, several Indian sentinels, who had been stationed at this, as at the other approaches to the city, took alarm and fled, rousing their countrymen by their cries. The priests, keeping their night watch on the summit of the teocallis, instantly caught the tidings and sounded their shells, while the huge drum in the desolate temple of the war-god sent forth those solemn tones, which, heard only in seasons of calamity, vibrated through every corner of the capital. The Spaniards saw that no time was to be lost. The bridge was brought forward and fitted with all possible expedition. Sandoval was the first to try its strength, and, riding across, was followed by his little body of cavalry, his infantry, and Tlascalan allies, who formed the first divisions of the army. Then came Cortes and his squadrons, with the baggage, ammunition wagons, and a part of the artillery. But before they had time to defile across the narrow passage, a gathering sound was heard, like that of a mighty forest agitated by the winds. It grew louder and louder, while on the dark waters of the lake was heard a plashing noise, as of many oars. Then came a few stones and arrows striking at random among the troops. They fell every moment faster and more furious, till they thickened into a terrible tempest, while the very heavens were rent with the yells and war cries of myriads of combatants, who seemed all at once to be swarming over land and lake!
The Spaniards pushed steadily on through this arrowy sleet, though the barbarians, dashing their canoes against the sides of the causeway, clambered up and broke in upon their ranks. But the Christians, anxious only to make their escape, declined all combat except for self-preservation. The cavaliers, spurring forward their steeds, shook off their assailants, and rode over their prostrate bodies, while the men on foot with their good swords or the butts of their pieces drove them headlong again down the sides of the dike.
But the advance of several thousand men, marching, probably, on a front of not more than fifteen or twenty abreast, necessarily required much time, and the leading files had already reached the second breach in the causeway before those in the rear had entirely traversed the first. Here they halted, as they had no means of effecting a passage, smarting all the while under unintermitting volleys from the enemy, who were clustered thick on the waters around this second opening. Sorely distressed, the vanguard sent repeated messages to the rear to demand the portable bridge. At length the last of the army had crossed, and Magarino and his sturdy followers endeavoured to raise the ponderous frame-work. But it stuck fast in the sides of the dike. In vain they strained every nerve. The weight of so many men and horses, and above all of the heavy artillery, had wedged the timbers so firmly in the stones and earth, that it was beyond their power to dislodge them. Still they laboured amidst a torrent of missiles, until, many of them slain, and all wounded, they were obliged to abandon the attempt.
The tidings soon spread from man to man, and no sooner was their dreadful import comprehended, than a cry of despair arose, which for a moment drowned all the noise of conflict. All means of retreat were cut off. Scarcely hope was left. The only hope was in such desperate exertions as each could make for himself. Order and subordination were at an end. Intense danger produced intense selfishness. Each thought only of his own life. Pressing forward, he trampled down the weak and the wounded, heedless whether it were friend or foe. The leading files, urged on by the rear, were crowded on the brink of the gulf. Sandoval, Ordaz, and the other cavaliers dashed into the water. Some succeeded in swimming their horses across. Others failed, and some, who reached the opposite bank, being overturned in the ascent, rolled headlong with their steeds into the lake. The infantry followed pell-mell, heaped promiscuously on one another, or struck down by the war clubs of the Aztecs; while many an unfortunate victim was dragged half-stunned on board their canoes, to be reserved for a protracted, but more dreadful death.
