The History of the Grecian War (1.74.1-1.74.3)

"Which being so, and evident that the whole state of the Grecians was embarked in their fleet, we conferred to the same the three things of most advantage, namely, the greatest number of galleys, the most prudent commander, and the most lively courage. For of four hundred galleys in the whole, our own were few less than two-thirds; and for commander Themistocles, who was the principal cause that the battle was fought in the strait whereby he clearly saved the whole business and whom, though a stranger, you yourselves have honoured for it more than any man that came unto you.

And a forwardness we showed more adventurous than any other in this, that when none of them had aided us by land before, and the rest of the cities, as far as to our own, were brought into servitude, we were nevertheless content both to quit our city and lose our goods, and even in that estate not to betray the common cause of the confederates, or divided from them to be unuseful, but to put ourselves into our navy and undergo the danger with them, and that without passion against you for not having formerly defended us in the like manner.

So that we may say that we have no less conferred a benefit upon you than we received it from you. You came indeed to aid us, but it was from cities inhabited and to the end you might still keep them so, and when you were afraid not of our danger but your own. Whereas we, coming from a city no more being, and putting ourselves into danger for a city hopeless ever to be again, saved both you in part and ourselves.
