After this they erected a trophy and stayed two or three days, expecting the Illyrians who were coming to Perdiccas upon hire; and Perdiccas meant afterwards to have gone on against the villages of Arrhibaeus one after another, and to have sitten still there no longer. But Brasidas, having his thoughts on Mende, lest if the Athenians came thither before his return it should receive some blow, seeing withal that the Illyrians came not, had no liking to do so, but rather to retire.
Whilst they thus varied, word was brought that the Illyrians had betrayed Perdiccas and joined themselves with Arrhibaeus. So that now it was thought good to retire by them both, for fear of these who were a warlike people; but yet for the time when to march, there was nothing concluded, by reason of their variance. The next night, the Macedonians and multitude of barbarians (as it is usual with great armies to be terrified upon causes unknown) being suddenly affrighted, and supposing them to be many more in number than they were, and even now upon them, betook themselves to present flight and went home. And Perdiccas, who at first knew not of it, they constrained when he knew, before he had spoken with Brasidas (their camps being far asunder), to be gone also.
