Conquest of Mexico
should the strangers return to the valley, to render them their homage and allegiance. The young caciques expressed their readiness to do so; but, as this must bring on them the vengeance of the Aztecs, they implored the general to furnish a sufficient force for their protection.
Cortés received a similar application from various other towns, which were disposed, could they do so with safety, to throw off the Mexican yoke. But he was in no situation to comply with their request. He now felt, more sensibly than ever, the incompetency of his means to his undertaking. "I assure your Majesty," he writes in his letter to the emperor, "the greatest uneasiness which I feel after all my labours and fatigues is from my inability to succour and support our Indian friends, your Majesty's loyal vassals." Far from having a force competent to this, he had scarcely enough for his own protection. His vigilant enemy had an eye on all his movements, and, should he cripple his strength by sending away too many detachments, or by employing them at too great a distance, would be prompt to take advantage of it. His only expeditions, hitherto, had been in the neighbourhood, where the troops, after striking some sudden and decisive blow, might speedily regain their quarters. The utmost watchfulness was maintained there, and the Spaniards lived in as constant preparation for an assault, as if their camp was pitched under the walls of Mexico.
On two occasions the general had sallied forth and engaged the enemy in the environs of Tezcuco. At one time a thousand canoes, filled with Aztecs, crossed the lake to gather in a large crop of Indian corn nearly ripe, on its borders. Cortés thought it important to secure this for himself. He accordingly marched out and gave battle to the enemy, drove them from the field, and swept away the rich harvest to the granaries of Tezcuco. Another time a strong body of Mexicans had established themselves in some neighbouring towns friendly to their interests. Cortés, again sallying, dislodged them from their quarters, beat them in several skirmishes, and reduced the places to obedience. But these enterprises demanded all his resources, and left him nothing to spare for his allies. In this exigency his fruitful genius suggested an expedient for supplying the deficiency of his means.
Some of the friendly cities without the valley, observing the numerous beacon-fires on the mountains, inferred that the Mexicans
