On his side there was an out-post of the Mexicans, at a place where one of the apertures in the causeway was too deep to be forded, and which had been strongly fortified by the enemy. He made a successful attack on this place, where he commanded in person, although the enemy made a brave resistance both by land and water; but he was obliged to retire at night without filling up the ditch, and he lost four Spaniards killed, and had above thirty wounded, the pass being commanded from the terraces of several houses in the water, and his brigantines were unable to get forward to protect his flanks, owing to the piles which the enemy had fixed under water. Guatimotzin and his Mexicans defended themselves with amazing bravery and resolution, trusting to wear us out and destroy us by continual assaults. On the 21st of June, the anniversary of the day of our first entry into Mexico, the enemy assailed us at every point of all our three attacks, both by land and water, in front, flanks, and rear, about two hours before day. The number fit for duty at our post on the causeway of Tacuba was 120 men, and all the allies attached to our detachment, were as usual off the causeway during the night. It was with the utmost difficulty that we were able to resist and repulse the enemy, of whom a great number were killed and wounded, losing two of our own soldiers. The enemy repeated their assaults on all the posts for two other nights successively; and on the third morning, just at day-break, they concentrated their whole force and made a desperate attack on our post. If our allies had been with us we should have been all lost. On this occasion our cavalry saved our rear, and our brigantines did signal service by clearing our flanks. After a most severe and long doubtful contest, we beat off the enemy and made four of their chiefs prisoners, eight of our soldiers being slain in this tough affair. I fear my readers may be tired of this constant repetition of battles, which my duty of historian compels me to relate: But if I were to give an account of every action which took place during the ninety-three days in which we were engaged in the siege of this great, strong, and populous city, every day and night of which time brought a perpetual succession of battles and assaults, my work would be without end, and would more resemble Amadis de Gaul and other romances of chivalry than a true history, which it really is.
