History of the Peloponnesian War

After this appeal to the gods he began hostilities. In the first place the Lacedaemonians, using the trees which they had cut down, built a stockade round Plataea, that in future no one might leave the place; then they began raising a mound against the town, hoping that with so large an army at work this would be the speediest way of taking it.

So they cut timber on Cithaeron and built a structure alongside the mound on either side of it, laying the logs like lattice-work I to form a sort of wall, that the mound might not spread too much.

Then they brought and threw into the space wood and stones and earth and anything else which when thrown on would serve to build up the mound. And for seventy days and nights continuously they kept on raising the mound, divided into relays, so that while some were carrying others might take sleep and food; and the Lacedaemonian commanders of auxiliaries together with the officers in charge of the contingents from the several cities kept them at their task.

But the Plataeans, seeing the mound rising, put together a framework of wood which they set on top of their own wall at the point where the mound was being constructed, and inside this frame they put bricks which they took from the neighbouring houses.

The timbers served to hold the bricks together, preventing the structure from becoming weak as it attained height, and they were protected by coverings of skins and hides, so that the workmen and woodwork might be safe and shielded from incendiary arrows.

The wall was mounting to a great height, and the opposing mound was rising with equal speed, when the Plataeans thought of a new expedient. They made an opening in that part of the city wall where the mound came into contact with it, and began to draw the earth in.
