Demosthenes Philippic 1 34

[34] More than that, Athenians, you will be depriving Philip of his principal source of revenue. And what is that? For the war against you he makes your allies pay by raiding their sea-borne commerce. Is there any further advantage? Yes, you will be out of reach of injury yourselves. Your past experience will not be repeated, when he threw a force into Lemnos and Imbros and carried your citizens away captive, when he seized the shipping at Geraestus and levied untold sums, or, to crown all, when he landed at Marathon and bore away from our land the sacred trireme, ¹ while you are still powerless to prevent these insults or to send your expeditions at the appointed times.
