Translated with the sanction of the author by William Purdie Dickson
A quick departure in a southerly direction towards Thessaly withdrew him at the last moment from imminent destruction; Pompeius had to content himself with having liberated Scipio from his position of peril. Caesar had meanwhile arrived unmolested at Apollonia. Immediately after the disaster of Dyrrhachium he had resolved if possible to transfer the struggle from the coast away into the interior, with the view of getting beyond the reach of the enemy's fleet--the ultimate cause of the failure of his previous exertions. The march to Apollonia had only been intended to place his wounded in safety and to pay his soldiers there, where his depots were stationed; as soon as this was done, he set out for Thessaly, leaving behind garrisons in Apollonia, Oricum, and Lissus.
The corps of Calvinus had also put itself in motion towards Thessaly; and Caesar could effect a junction with the reinforcements coming up from Italy, this time by the land-route through Illyria--two legions under Quintus Cornificius--still more easily in Thessaly than in Epirus. Ascending by difficult paths in the valley of the Aous and crossing the mountain-chain which separates Epirus from Thessaly, he arrived at the Peneius; Calvinus was likewise directed thither, and the junction of the two armies was thus accomplished by the shortest route and that which was least exposed to the enemy. It took place at Aeginium not far from the source of the Peneius. The first Thessalian town before which the now united army appeared, Gomphi, closed its gates against it; it was quickly stormed and given up to pillage, and the other towns of Thessaly terrified by this example submitted, so soon as Caesar's legions merely appeared before the walls. Amidst these marches and conflicts, and with the help of the supplies-- albeit not too ample--which the region on the Peneius afforded, the traces and recollections of the calamitous days through which they had passed gradually vanished.
