About this time, the inhabitants of the cities on the lake grew weary of the long protracted warfare, and sent deputations to our general, offering to submit themselves to his authority, and declaring that they had been constrained by the Mexicans to persist hitherto in their hostilities against us. Cortes received them very graciously, and assured them of his protection, providing that they should conduct themselves properly for the future, and give him their assistance by supplying canoes and provisions to our army, and in the construction of barracks for the troops. They readily promised all this, but performed very badly. Cortes had huts built for his detachment[7]; but the rest of us remained exposed to the weather, which was exceedingly severe and distressing, as it rained almost incessantly during June, July, and August. Our detachment on the causeway of Tacuba continued our approach towards Mexico, filling up every ditch and canal as we advanced by means of the materials of the houses which we destroyed; and we every day gained possession of temples or houses, which stood apart from each other, and of the bridges by which they communicated. To avoid jealousy, our three companies took the duties of working and fighting alternately, our allies giving most important assistance in pulling down the houses and filling up the ditches and cross-cuts of the causeway. Every evening the whole of our men stood to their arms, and we sent off our allies before us, before retreating to our post for the night. During all this time, Sandoval, who carried on his approach from Tepejacac, was obliged to sustain continual attacks from the enemy; as likewise was Cortes, who now commanded at the third attack.
