There were no less than seven of these canals intersecting the great street of Tlacopan,[141] and at every one the same scene was renewed, the Mexicans making a gallant stand and inflicting some loss, at each, on their persevering antagonists. These operations consumed two days, when, after incredible toil, the Spanish general had the satisfaction to find the line of communication completely re-established through the whole length of the avenue, and the principal bridges placed under strong detachments of infantry. At this juncture, when he had driven the foe before him to the farthest extremity of the street, where it touches on the causeway, he was informed that the Mexicans, disheartened by their reverses, desired to open a parley with him respecting the terms of an accommodation, and that their chiefs awaited his return for that purpose at the fortress. Overjoyed at the intelligence, he instantly rode back, attended by Alvarado, Sandoval, and about sixty of the cavaliers, to his quarters. The Mexicans proposed that he should release the two priests captured in the temple, who might be the bearers of his terms and serve as agents for conducting the negotiations. They were accordingly sent with the requisite instructions to their countrymen. But they did not return. The whole was an artifice of the enemy, anxious to procure the liberation of their religious leaders, one of whom was their _teoteuctli_, or high-priest, whose presence was indispensable in the probable event of a new coronation.
