The words of Thucydidês here are—Ἔπειτα δὲ ξύμβασιν ποιησάμενοι καὶ ξυμμαχίαν ἀναγκαίαν πρὸς τὸν Περδίκκαν, ὡς αὐτοὺς κατήπειγεν ἡ Ποτίδαια καὶ ὁ Ἀριστεὺς παρεληλυθὼς, ~ἀπανίστανται ἐκ τῆς Μακεδονίας~, καὶ ἀφικόμενοι ἐς Βέροιαν κἀκεῖθεν ἐπιστρέψαντες, καὶ πειράσαντες πρῶτον τοῦ χωρίου καὶ οὐχ ἑλόντες, ἐπορεύοντο κατὰ γῆν πρὸς τὴν Ποτίδαιαν—ἅμα δὲ νῆες παρέπλεον ἑβδομήκοντα. “The natural route from Pydna to Potidæa (observes Dr. Arnold in his note) lay along the coast; and Berœa was _quite out of the way_, at some _distance to the westward_, near the fort of the Bermian mountains. But the hope of surprising Berœa induced the Athenians to deviate from their direct line of march; then, after the failure of this treacherous attempt, they returned again to the sea-coast, and continued to follow it till they arrived at Gigônus.” I would remark upon this: 1. The words of Thucydidês imply that Berœa was _not in_ Macedonia, but _out_ of it (see Poppo, Proleg. ad Thucyd. vol. ii, pp. 408-418). 2. He uses no expression which in the least implies that the attempt on Berœa on the part of the Athenians was _treacherous_, that is, contrary to the convention just concluded; though, had the fact been so, he would naturally have been led to notice it, seeing that the deliberate breach of the convention was the very first step which took place after it was concluded. 3. What can have induced the Athenians to leave their fleet and march near twenty miles inland to Mount Bermius and Berœa, to attack a Macedonian town which they could not possibly hold,—when they cannot even stay to continue the attack on Pydna, a position maritime, useful, and tenable,—in consequence of the pressing necessity of taking immediate measures against Potidæa? 4. If they were compelled by this latter necessity to patch up a peace on any terms with Perdikkas, would they immediately endanger this peace by going out of their way to attack one of his forts? Again, Thucydidês says, “that, proceeding by slow land-marches, they reached Gigônus, and encamped _on the third day_,”—κατ᾽ ὀλίγον δὲ προϊόντες τριταῖοι ἀφίκοντο ἐς Γίγωνον καὶ ἐστρατοπεδεύσαντο. The computation of time must here be made either from Pydna or from Berœa; and the reader who examines the map will see that neither from the one nor the other—assuming the Berœa on Mount Bermius—would it be possible for an army to arrive at Gigônus on the third day, marching round the head of the gulf, with easy days’ marches; the more so, as they would have to cross the rivers Lydias, Axius. and Echeidôrus, all not far from their mouths,—or, if these rivers could not be crossed, to get on board the fleet and reland on the other side.
