History of the Peloponnesian War

Now their treasure being by these wars and by the detriment sustained from Deceleia and other great expenses that came upon them at a very low ebb, about this time they imposed on such as were under their dominion a twentieth part of all goods passing by sea for a tribute, by this means to improve their comings in. For their expenses were not now as before, but so much greater by how much the war was greater, and their revenue besides cut off.

The Thracians, therefore, that came too late to go with Demosthenes, they presently sent back, as being unwilling to lay out money in such a scarcity, and gave the charge of carrying them back to Diitrephes, with command as he went along those coasts (for his way was through the Euripus), if occasion served, to do somewhat against the enemy.

He accordingly landed them by Tanagra and hastily fetched in some small booty. Then going over the Euripus from Chalcis in Euboea, he disbarked again in Boeotia and led his soldiers towards Mycalessus, and lay all night at the temple of Mercury undiscovered, which is distant from Mycalessus about sixteen furlongs.
