After this Thucydides proceeded to arrange matters at Eion, in order to insure its safety for the present, if Brasidas should attack, and also for the future, receiving those who chose to come thither from the upper town according to the terms of the truce.[*](cf. 4.105.2.)
And Brasidas suddenly sailed down the river to Eion with many boats, in the hope that by taking the point which juts out from the wall he might gain command of the entrance, and at the same time he made an attempt by land; but he was beaten back at both points, and then proceeded to put matters in order at Amphipolis.
