For several years at the beginning of the war, Sparta remained largely inert. Spartan troops may have been involved in some of the early battles of the war, but if so, they were not specifically mentioned in any sources. In 458 BC or 457 BC, Sparta at last made a move, but not directly at Athens. A war had broken out between Athens' ally Phocis and Doris, across the Corinthian Gulf from the Peloponnese. Doris was traditionally identified as the homeland of the Dorians, and the Spartans, being Dorians, had a long-standing alliance with that state. Accordingly, a Spartan army under the command of the general Nicomedes, acting as deputy for the under-age king Pleistoanax, was dispatched across the Corinthian Gulf to assist. This army forced the Phocians to accept terms, but while the army was in Doris an Athenian fleet moved into position to block its return across the Corinthian Gulf.
