Josephus writes, "While the Temple was ablaze, the attackers plundered it, and countless people who were caught by them were slaughtered. There was no pity for age and no regard was accorded rank; children and old men, laymen and priests, alike were butchered; every class was pursued and crushed in the grip of war, whether they cried out for mercy or offered resistance.
The Temple Mount, everywhere enveloped in flames, seemed to be boiling over from its base; yet the blood seemed more abundant than the flames and the numbers of the slain greater than those of the slayers. The soldiers climbed over heaps of bodies as they chased the fugitives." (Josephus' account appears in: Cornfield, Gaalya ed., Josephus, The Jewish War [1982]; Duruy, Victor, History of Rome vol. V [1883].)
