Flavius Josephus, The Wars of the Jews
William Whiston, A.M., Ed.

[29] When this accident had unexpectedly happened, the minds of both parties were variously affected; for though one would expect that the Jews would be discouraged, because this fall of their wall was unexpected by them, and they had made no provision in that case, yet did they pull up their courage, because the tower of Antonia itself was still standing; as was the unexpected joy of the Romans at this fall of the wall soon quenched by the sight they had of another wall, which John and his party had built within it. However, the attack of this second wall appeared to be easier than that of the former, because it seemed a thing of greater facility to get up to it through the parts of the former wall that were now thrown down. This new wall appeared also to be much weaker than the tower of Antonia, and accordingly the Romans imagined that it had been erected so much on the sudden, that they should soon overthrow it: yet did not any body venture now to go up to this wall; for that such as first ventured so to do must certainly be killed.
