History of the Peloponnesian War

At every ten battlements stood a great tower of a just breadth to comprehend both walls and reach from the outmost to the inmost front of the whole, so that there was no passage by the side of a tower but through the midst of it.

And such nights as there happened any storm of rain, they used to quit the battlements of the wall and to watch under the towers, as being not far asunder and covered beside overhead. Such was the form of the wall wherein the Peloponnesians kept their watch.

The Plataeans, after they were ready and had attended a tempestuous night, and withal moonless, went out of the city and were conducted by the same men that were the authors of the attempt. And first they passed the ditch that was about the town and then came up close to the wall of the enemy, who, because it was dark, could not see them coming; and the noise they made as they went could not be heard for the blustering of the wind.

And they came on besides at a good distance one from the other, that they might not be betrayed by the clashing of their arms, and were but lightly armed and not shod but on the left foot for the more steadiness in the wet.

They came thus to the battlements in one of the spaces between tower and tower, knowing that there was now no watch kept there. And first came they that carried the ladders and placed them to the wall: then twelve lightly armed, only with a dagger and a breastplate, went up, led by Ammeas the son of Coroebus, who was the first that mounted; and they that followed him went up into either tower six. To these succeeded others lightly armed that carried the darts for whom they that came after carried targets at their backs that they might be the more expedite to get up, which targets they were to deliver to them when they came to the enemy.
