protection, Cortés ordered fire to be set to the buildings. This was no very difficult matter, since, although chiefly of stone, they were filled with mats, cane-work, and other combustible materials, which were soon in a blaze. But the buildings stood separated from one another by canals and draw-bridges, so that the flames did not easily communicate to the neighboring edifices. Hence the labor of the Spaniards was incalculably increased, and their progress in the work of destruction—fortunately for the city—was comparatively slow.8 They did not relax their efforts, however, till several hundred houses had been consumed, and the miseries of a conflagration, in which the wretched inmates perished equally with the defenders, were added to the other horrors of the scene.
The day was now far spent. The Spaniards had been everywhere victorious. But the enemy, though driven back on every point, still kept the field. When broken by the furious charges of the cavalry, he soon rallied behind the temporary defences, which, at different intervals, had been thrown across the streets, and, facing about, renewed the fight with undiminished courage, till the sweeping away of the barriers by the cannon of the assailants left a free passage for the movements of their horse. Thus the action was a succession of rallying and retreating, in which both parties suffered much, although the loss inflicted on the Indians was probably tenfold greater than that of the Spaniards. But the Aztecs could better afford the loss of a hundred lives than their antagonists that of one. And, while the Spaniards showed an array broken and obviously thinned in numbers, the Mexican army, swelled by the tributary levies which flowed in upon it from the neighboring streets, exhibited, with all its losses, no sign of diminution. At length, sated with carnage, and exhausted by toil and hunger, the Spanish commander drew off his men, and sounded a retreat.9
On his way back to his quarters, he beheld his friend the secretary Duero, in a street adjoining, unhorsed, and hotly engaged with a body of
