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.
