On the top of the eminence was a blazing beacon, serving to notify to the inhabitants of the capital when the Spanish fleet weighed anchor. Before Cortés had regained his brigantine, the canoes and _piraguas_ of the enemy had left the harbors of Mexico, and were seen darkening the lake for many a rood. There were several hundred of them, all crowded with warriors, and advancing rapidly by means of their oars over the calm bosom of the waters.[2] Cortés, who regarded his fleet, to use his own language, as “the key of the war,” felt the importance of striking a decisive blow in the first encounter with the enemy.[3] It was with chagrin, therefore, that he found his sails rendered useless by the want of wind. He calmly awaited the approach of the Indian squadron, which, however, lay on their oars at something more than musket-shot distance, as if hesitating to encounter these leviathans of their waters. At this moment, a light air from land rippled the surface of the lake; it gradually freshened into a breeze, and Cortés, taking advantage of the friendly succor, which he may be excused, under all the circumstances, for regarding as especially sent him by Heaven, extended his line of battle, and bore down, under full press of canvas, on the enemy.[4] The latter no sooner encountered the bows of their formidable opponents than they were overturned and sent to the bottom by the shock, or so much damaged that they speedily filled and sank. The water was covered with the wreck of broken canoes, and with the bodies of men struggling for life in the waves and vainly imploring their companions to take them on board their over-crowded vessels. The Spanish fleet, as it dashed through the mob of boats, sent off its volleys to the right and left with a terrible effect, completing the discomfiture of the Aztecs. The latter made no attempt at resistance, scarcely venturing a single flight of arrows, but strove with all their strength to regain the port from which they had so lately issued. They were no match in the chase, any more than in the fight, for their terrible antagonist, who, borne on the wings of the wind, careered to and fro at his pleasure, dealing death widely around him, and making the shores ring with the thunders of his ordnance. A few only of the Indian flotilla succeeded in recovering the port, and, gliding up the canals, found a shelter in the bosom of the city, where the heavier burden of the brigantines made it impossible for them to follow. This victory, more complete than even the sanguine temper of Cortés had prognosticated, proved the superiority of the Spaniards, and left them, henceforth, undisputed masters of the Aztec sea.[5]
