History of the Peloponnesian War

Having made this protestation to the gods, he made ready his army for the war. And first having felled trees, he therewith made a palisade about the town that none might go out. That done, he raised a mount against the wall, hoping with so great an army all at work at once, to have quickly taken it.

And having cut down wood in the hill Cithaeron, they built a frame of timber and wattled it about on either side to serve instead of walls to keep the earth from falling too much away and cast into it stones and earth and whatsoever else would serve to fill it up.
