For their expenses were not on the same scale as before, but much greater; inasmuch as the war also was greater, while their revenues were being destroyed.

Accordingly he landed them at Tanagra, and carried off some plunder in a hurried manner; and then in the evening sailed across the Euripus from Chalcis in Euboea, and landing them in Boeotia, led them against Mycalessus.
