[HEGESANDRIDAS.] Later in the same year, soon after Hegesandridas had sailed from Euboea to act in concert with Mindarus in the north, Thymochares was sent from Athens in the same direction with a few ships. A battle ensued between the squadron of Hegesandridas and the portion of the Athenian navy to which Thymochares had brought reinforcements. and the Peloponnesians proved victorious. (Xen. Hell. i. 50.1.)
