The arguments of his Indian allies prevailed with the Spanish commander, who resolved to propitiate the good will of the Tlascalans by an embassy. He selected four of the principal Cempoallans for this, and sent by them a martial gift,--a cap of crimson cloth, together with a sword and a cross-bow, weapons which, it was observed, excited general admiration among the natives. He added a letter, in which he asked permission to pass through their country. He expressed his admiration of the valor of the Tlascalans, and of their long resistance to the Aztecs, whose proud empire he designed to humble.[97] It was not to be expected that this epistle, indited in good Castilian, would be very intelligible to the Tlascalans. But Cortés communicated its import to the ambassadors. Its mysterious characters might impress the natives with an idea of superior intelligence, and the letter serve instead of those hieroglyphical missives which formed the usual credentials of an Indian ambassador.[98] The Spaniards remained three days in this hospitable place, after the departure of the envoys, when they resumed their progress. Although in a friendly country, they marched always as if in a land of enemies, the horse and light troops in the van, with the heavy-armed and baggage in the rear, all in battle-array. They were never without their armor, waking or sleeping, lying down with their weapons by their sides. This unintermitting and restless vigilance was, perhaps, more oppressive to the spirits than even bodily fatigue. But they were confident in their superiority in a fair field, and felt that the most serious danger they had to fear from Indian warfare was surprise. “We are few against many, brave companions,” Cortés would say to them; “be prepared, then, not as if you were going to battle, but as if actually in the midst of it!”[99] The road taken by the Spaniards was the same which at present leads to Tlascala; not that, however, usually followed in passing from Vera Cruz to the capital, which makes a circuit considerably to the south, towards Puebla, in the neighborhood of the ancient Cholula. They more than once forded the stream that rolls through this beautiful plain, lingering several days on the way, in hopes of receiving an answer from the Indian republic. The unexpected delay of the messengers could not be explained, and occasioned some uneasiness.
