History of the Peloponnesian War

"But it may be some rely on this, that we exceed them in arms and multitude of soldiers so that we may waste their territories with incursions.

But there is much other land under their dominion, and by sea they are able to bring in whatsoever they shall stand in need of.

Again, if we essay to alienate their confederates, we must aid them with shipping because the most of them are islanders.

What a war then will this of ours be? For unless we have the better of them in shipping or take from them their revenue whereby their navy is maintained, we shall do the most hurt to ourselves.
