The History of the Grecian War (1.35.3-1.35.5)

And sure it were very unreasonable that the Corinthians should have the liberty to man their fleet out of the cities comprised in the league, and out of any other parts of Greece, and not the least out of places in your dominion, and we be denied both the league now propounded and also all other help from whencesoever. And if they impute it to you as a fault that you grant our request, we shall take it for a greater that you grant it not.

For therein you shall reject us that are invaded and be none of your enemies; and them, who are your enemies and make the invasion, you shall not only not oppose but also suffer to raise unlawful forces in your dominions. Whereas you ought in truth either not to suffer them to take up mercenaries in your states, or else to send us succours also in such manner as you shall think good yourselves, but especially by taking us into your league and so aiding us.

Many commodities, as we said in the beginning, we show unto you, but this for the greatest: that whereas they are your enemies (which is manifest enough) and not weak ones but able to hurt those that stand up against them, we offer you a naval, not a terrestrial, league; and the want of one of these is not as the want of the other. Nay, rather your principal aim, if it could be done, should be to let none at all have shipping but yourselves, or at least, if that cannot be, to make such your friends as are best furnished therewith.
