Alexander prepared to meet his enemy in Macedonia, but the king anticipated him, and, reaching Larissa, was admitted into the city. Alexander withdrew to Pherae whilst the Macedonian King placed a garrison in Larissa, as well as in Crannon, which had also come over to him. But once the bulk of the Macedonian army had retired, the states of Thessaly feared the return and vengeance of Alexander, and so sent for aid to Thebes, whose policy it was to put a check on any neighbour who might otherwise become too formidable. Thebes accordingly dispatched Pelopidas to the aid of Thessaly. On arrival of Pelopidas at Larissa, whence according to Diodorus, he dislodged the Macedonian garrison, Alexander presented himself and offered submission. When Pelopidas expressed indignation at the tales of Alexander's profligacy and cruelty, Alexander took alarm and fled.
