History of the Peloponnesian War

The most numerous and compact body rushed into a large building next to the city wall: the doors on the side of the street happened to be open, and the Thebans fancied that they were the gates of the town, and that there was a passage right through to the outside.

The Plataeans, seeing their enemies in a trap, now consulted whether they should set fire to the building and burn them just as they were, or whether there was anything else that they could do with them;

until at length these and the rest of the Theban survivors found wandering about the town agreed to an unconditional surrender of themselves and their arms to the Plataeans.
