When his proposals of peace addressed to the king, which substantially amounted to a restoration of the state of matters before the war, met with no acceptance, he advanced just as he had landed, from the harbours of Epirus to Boeotia, defeated the generals of the enemy Archelaus and Aristion there at Mount Tilphossium, and after that victory possessed himself almost without resistance of the whole Grecian mainland with the exception of the fortresses of Athens and the Piraeeus, into which Aristion and Archelaus had thrown themselves, and which he failed to carry by a coup de main.

A Roman division under Lucius Hortensius occupied Thessaly and made incursions into Macedonia; another under Munatius stationed itself before Chalcis, to keep off the enemy's corps under Neoptolemus in Euboea; Sulla himself formed a camp at Eleusis and Megara, from which he commanded Greece and the Peloponnesus, and prosecuted the siege of the city and harbour of Athens.
