History of the Peloponnesian War

Such were the preparations and such the feelings with which the contest opened.The allies of the two belligerents were the following.

These were the allies of Lacedaemon: all the Peloponnesians within the Isthmus except the Argives and Achaeans, who were neutral; Pellene being the only Achaean city that first joined in the war, though her example was afterwards followed by the rest. Outside Peloponnese the Megarians, Locrians, Boeotians, Phocians, Ambraciots, Leucadians, and Anactorians.

Of these, ships were furnished by the Corinthians, Megarians, Sycyonians, Pellenians, Eleans, Ambraciots, and Leucadians; and cavalry by the Boeotians, Phocians, and Locrians. The other states sent infantry. This was the Lacedaemonian confederacy.
