The time for clemency was past; the longer the civil war lasted, the more remorseless and implacable it became.
The Political Effects of the Battle of Pharsalus The East Submits Some time elapsed, before the consequences of the 9th of August 706 could be fully discerned.

What admitted of least doubt, was the passing over to the side of Caesar of all those who had attached themselves to the party vanquished at Pharsalus merely as to the more powerful; the defeat was so thoroughly decisive, that the victor was joined by all who were not willing or were not obliged to fight for a lost cause.

All the kings, peoples, and cities, which had hitherto been the clients of Pompeius, now recalled their naval and military contingents and declined to receive the refugees of the beaten party; such as Egypt, Cyrene, the communities of Syria, Phoenicia, Cilicia and Asia Minor, Rhodes, Athens, and generally the whole east.

In fact Pharnaces king of the Bosporus pushed his officiousness so far, that on the news of the Pharsalian battle he took possession not only of the town of Phanagoria which several years before had been declared free by Pompeius, and of the dominions of the Colchian princes confirmed by him, but even of the kingdom of Little Armenia which Pompeius had conferred on king Deiotarus.

Almost the sole exceptions to this general submission were the little town of Megara which allowed itself to be besieged and stormed by the Caesarians, and Juba king of Numidia, who had for long expected, and after the victory over Curio expected only with all the greater certainty, that his kingdom would be annexed by Caesar, and was thus obliged for better or for worse to abide by the defeated party.
The Aristocracy after the Battle of Pharsalus In the same way as the client communities submitted to the victor of Pharsalus, the tail of the constitutional party--all who had joined it with half a heart or had even, like Marcus Cicero and his congeners, merely danced around the aristocracy like the witches around the Brocken--approached to make their peace with the new monarch, a peace accordingly which his contemptuous indulgence readily and courteously granted to the petitioners.
