Philip swore to the treaty, but he delayed the departure of the Athenian envoys, who had yet to receive the oaths from Macedon's allies in Thessaly and elsewhere. Finally, peace was sworn at Pherae, where Philip accompanied the Athenian delegation, after he had completed his military preparations to move south. Demosthenes accused the other envoys of venality and of facilitating Philip's plans with their stance.* G. Cawkwell, "Philip II of Macedon", 102–105; D. M. MacDowell, "Demosthenes the Orator", ch. 12.</ref> Just after the conclusion of the Peace of Philocrates, Philip passed Thermopylae, and subdued Phocis; Athens made no move to support the Phocians.* D. M. MacDowell, "Demosthenes the Orator", ch. 12.</ref> Supported by Thebes and Thessaly, Macedon took control of Phocis' votes in the Amphictyonic League, a Greek religious organisation formed to support the greater temples of Apollo and Demeter. Despite some reluctance on the part of the Athenian leaders, Athens finally accepted Philip's entry into the Council of the League.* D. M. MacDowell, "Demosthenes the Orator", ch. 12.</ref> Demosthenes was among those who adopted a pragmatic approach, and recommended this stance in his oration "On the Peace". For Edmund M. Burke, this speech heralds a maturation in Demosthenes' career: after Philip's successful campaign in 346 BC, the Athenian statesman realised that, if he was to lead his city against the Macedonians, he had "to adjust his voice, to become less partisan in tone".
