from them as far forward as possible all sorts of projectiles which are usually shot from military engines.[63] He directed the archers, who had also entered the water, to shoot their arrows from the middle of the river. But Glaucias durst not advance within range of the missiles; so that the Macedonians passed over in such safety, that not one of them lost his life in the retreat. Three days after this, Alexander discovered that Clitus and Glaucias lay carelessly encamped; that neither were their sentinels on guard in military order, nor had they protected themselves with a rampart or ditch, as if they imagined he had withdrawn through fear; and that they had extended their line to a disadvantageous length. He therefore crossed the river again secretly, at the approach of night, leading with him the shield-bearing guards, the Agrianians, the archers, and the brigades of Perdiccas[64] and Coenus,[65] after having given orders for the rest of the army to follow. As soon as he saw a favourable opportunity for the attack, without waiting for all to be present, he despatched the archers and Agrianians against the foe. These, being arranged in phalanx, fell unawares with the most furious charge upon their flank, where they were likely to come into conflict with their weakest point, and slew some of them still in their beds, others being easily caught in their flight. Accordingly, many were there captured and killed, as were many also in the disorderly and panic-stricken retreat which ensued. Not a few, moreover, were taken prisoners. Alexander kept up the pursuit as far as the Taulantian mountains; and as many of them as escaped, preserved their lives by throwing away their arms. Clitus first fled for refuge into the city, which, however, he set on fire, and withdrew to Glaucias, in the land of the Taulantians. CHAPTER VII. REVOLT OF THEBES (_September_, B.C. 335). While these events were occurring, some of the exiles who had been banished from Thebes, coming to the city by night, and being brought in by some of the citizens, in order to effect a change in the government, apprehended and slew outside the Cadmea,[66] Amyntas and Timolaüs,[67] two of the men who held that fortress, having no suspicion that any hostile attempt was about to be made. Then entering the public assembly, they incited the Thebans to revolt from Alexander, holding out to them as pretexts the ancient and glorious words, liberty and freedom of speech, and urging them now at last to rid themselves of the heavy yoke of the Macedonians. By stoutly maintaining that Alexander had been killed in Illyria they gained more power in persuading the multitude;[68] for this report was prevalent, and for many reasons it gained credit, both because he had been absent a long time, and because no news had arrived from him. Accordingly, as is usual in such cases, not knowing the facts, each man conjectured what was most pleasing to himself.
