The tale recorded by Zosimus
Gerontius, who had abandoned the pass of Thermopylæ, took no measures to defend the Isthmus of Corinth, or the difficult passes of Mount Geranion, so that Alaric marched unopposed into the Peloponnesus, and, in a short time, captured every city in it without meeting with any resistance. Corinth, Argos, and Sparta, were all plundered by the Goths. The security in which Greece had long remained, and the policy of the government, which discouraged their independent institutions, had conspired to leave the province without protection, and the people without arms. The facility which Alaric met with in effecting his conquest, and his views, which were directed to obtain an establishment in the empire as an imperial officer or feudatory governor, rendered the conduct of his army not that of avowed enemies. Yet it often happened that they laid waste everything in the line of their march, burned villages, and massacred the inhabitants.
Alaric passed the winter in the Peloponnesus without encountering any opposition from the people; yet many of the Greek cities still kept a body of municipal police, which might surely have taken the field, had the imperial officers performed their duty and endeavoured to organise a regular resistance in the country districts. The moderation of the Goth, and the treason of the Roman governor, seem both attested by this circumstance. The government of the Eastern Empire had fallen into such disorder at the commencement of the reign of Arcadius, that even after Rufinus had been assassinated by the army the new ministers of the empire gave themselves very little concern about the fate of Greece.
Honorius had a more able, active, and ambitious minister in Stilicho, and he determined to punish the Goths for their audacity in daring to establish themselves in the empire without the imperial authority. Stilicho had attempted to save Thessaly in the preceding year, but had been compelled to return to Italy, after he had reached Thessalonica, by an express order of the emperor Arcadius, or rather of his minister Rufinus. In the spring of the year 396, he assembled a fleet at Ravenna, and transported his army directly to Corinth, which the Goths do not appear to have garrisoned, and where, probably, the Roman governor still resided. Stilicho’s army, aided by the inhabitants, soon cleared the open country of the Gothic bands, and Alaric drew together the remains of his diminished army in the elevated plain of Mount Pholoe, which has since served as a point of retreat for the northern invaders of Greece. Stilicho contented himself with occupying the passes with his army; but his carelessness, or the relaxed discipline of his troops, soon afforded the watchful Alaric an opportunity of escaping with his army, of carrying off all the plunder which they had collected, and, by forced marches, of gaining the Isthmus of Corinth.
