Delium (Peloponnesian War).
Fought B.C. 424 between the Athenians under Hippocrates. 17,000 strong, and the Bœotians under Pagondas, 18,000 strong. The armies met on a plain before Delium, and after an obstinate encounter, in which the Thebans on the right overpowered the Athenians, while their left attack was repulsed, the appearance of a large body of cavalry on their flank alarmed the Athenians, who broke and fled, Hippocrates fell in the battle.
