Quauhtemoctzin, with his generals and papas, finding that no advantage was to be gained over us in this way, determined to attack our position at Tlacupa with his united forces. This was accordingly put into practice as soon as day began to dawn, and they fell upon us from all sides with great intrepidity, and threw our line into disorder; but at this moment it pleased the Almighty to refresh our strength; our troops rallied again, and in their turn fell courageously upon the infuriated foe. Our brigantines too lent us what assistance they could, and the cavalry, with lances fixed, spurred their horses on, while our crossbow-men and musketeers, strove to do their utmost; we others, armed with swords, thrusting and cutting in among the enemy most valiantly, so that at last we drove them back. This was a more terrible battle than any we had fought on the causeways. Alvarado himself was wounded in the head, and eight of our men were killed. If the Tlascallans had likewise encamped this night on the causeway, we should no doubt have suffered more severely, as their numbers would have embarrassed our movements; but experience had taught us prudence, and each night we ordered them to draw off to Tlacupa, and we only considered ourselves safe when assured they had left the causeway.
In this engagement we slew a great number of the enemy, and among the many men we took prisoners there were four personages of high rank.
By this time the reader will certainly be wearied of reading of battles which were every day renewed; but I have not exaggerated them, for during the ninety-three days we lay before this great and strong city, we were compelled to fight both day and night almost without intermission; and certainly, of all these numerous engagements, I am at least bound to mention the most striking occurrences. If I were desirous of relating every circumstance I should never finish, and my book would resemble 'Amadis de Gaule,' and other such romances, whose authors can find no end to their pretty stories. I will, however, be as brief as possible in my further account of this siege, and hasten on to St. Hippolytus' day, when we subdued this vast city, and took Quauhtemoctzin, with all his generals, prisoners. But, before we were so far successful, we suffered great hardships, and the whole of us were near perishing in the attempt, particularly the division under Cortes, as the reader will shortly see.
