Still, notwithstanding the advantages gained over the enemy in the field, the Tlascalans were sorely pressed by their long hostilities with a foe so far superior to themselves in numbers and resources. The Aztec armies lay between them and the coast, cutting off all communication with that prolific region, and thus limited their supplies to the products of their own soil and manufacture. For more than half a century they had neither cotton, nor cacao, nor salt. Indeed, their taste had been so far affected by long abstinence from these articles that it required the lapse of several generations after the Conquest to reconcile them to the use of salt at their meals.[114] During the short intervals of war, it is said, the Aztec nobles, in the true spirit of chivalry, sent supplies of these commodities as presents, with many courteous expressions of respect, to the Tlascalan chiefs. This intercourse, we are assured by the Indian chronicler, was unsuspected by the people. Nor did it lead to any further correspondence, he adds, between the parties, prejudicial to the liberties of the republic, “which maintained its customs and good government inviolate, and the worship of its gods.”[115] Such was the condition of Tlascala at the coming of the Spaniards; holding, it might seem, a precarious existence under the shadow of the formidable power which seemed suspended like an avalanche over her head, but still strong in her own resources, stronger in the indomitable temper of her people; with a reputation established throughout the land for good faith and moderation in peace, for valor in war, while her uncompromising spirit of independence secured the respect even of her enemies. With such qualities of character, and with an animosity sharpened by long, deadly hostility with Mexico, her alliance was obviously of the last importance to the Spaniards, in their present enterprise. It was not easy to secure it.[116]
