First then, men of Athens, I propose to equip fifty war-galleys; next you must make up your minds to embark and sail in them yourselves, if necessary. Further I recommend the provision of transports and other vessels, sufficient for the conveyance of half our cavalry.

All this is a necessary provision against Philip’s sudden raids from Macedonia against Thermopylae, the Chersonese, Olynthus, or where he will. You must present to his mind the consideration that you may possibly shake off your excessive apathy and strike out as you did at Euboea, and before that, as we are told, at Haliartus, and quite recently at Thermopylae.The Athenians sent a force to Euboea in 357 (cf. Dem. 1.8). They helped the Thebans to defeat Lysander at Haliartus in Boeotia in 395. In 352, when Philip tried to march from Thessaly against Phocis, he was checked by the dispatch of an Athenian fleet to Thermopylae.
