Abstract
The relatively plentiful sources for the year 346 pose several questions which have never been satisfactorily answered. Why did Philip insist on an alliance with Athens as a precondition of the peace ? Did Demosthenes simply invent the promises of Philip which he claims Aeschines reported to the Athenian assembly in Skirophorion? Why were the Athenians frightened when Philip got control of Thermopylae? They had long expected him to settle the Sacred War, and such action surely required occupation of the pass. The correct answer to these questions indicates that Philip had two alternative plans in 346. ‘Plan A’ was with the aid of the Athenians to turn on Thebes. By this move, he would reduce the power of the second greatest city in Greece and thus eliminate the possibility of a combination of Athens and Thebes, which might be sufficiently powerful to block his ambitions
