History of the Peloponnesian War

The next day he cometh to the city, being a very great one, and taketh it; for they kept no watch nor expected that any man would have come in and assaulted them so far from the sea. Their walls also were but weak, in some places fallen down, and in others low-built, and their gates open through security.

The Thracians, entering into Mycalessus, spoiled both houses and temples, slew the people without mercy on old or young, but killed all they could light on, both women and children, yea, and the labouring cattle, and whatsoever other living thing they saw. For the nation of the Thracians, where they dare, are extreme bloody, equal to any of the barbarians. Insomuch as there was put in practice at this time, besides other disorder, all forms of slaughter that could be imagined;

they likewise fell upon the schoolhouse, which was in the city a great one, and the children newly entered into it; and killed them every one. And the calamity of the whole city, as it was as great as ever befell any, so also was it more unexpected and more bitter.
