Histories

But before despatching the troops, Aryandes sent a herald to +Al Marj [20.833,32.5] (inhabited place), Al Jabal al Akhdar, Libya, Africa Barce to ask who it was who had killed Arcesilaus. The Barcaeans answered that it was the deed of the whole city, for the many wrongs that Arcesilaus had done them; when he heard this, Aryandes sent his troops with Pheretime.

This was the pretext; but I myself think that the troops were sent to subjugate Libya [17,25] (nation), AfricaLibya. For the Libyan tribes are many and of different kinds, and though a few of them were the king's subjects, the greater part cared nothing for Darius.
