History of the Peloponnesian War

At length both these and all the rest of the Thebans that were straggling in the city agreed to yield themselves and their arms to the Plataeans at discretion.

And this success had they that entered into Plataea.

But the rest of the Thebans that should with their whole power have been there before day for fear the surprise should not succeed with those that were in, came so late with their aid that they heard the news of what was done by the way.

Now Plataea is from Thebes seventy furlongs, and they marched the slower for the rain which had fallen the same night. For the river Asopus was swollen so high that it was not easily passable.
