History of the Peloponnesian War

This was chiefly done, by the Syracusans, because they saw that the place afforded an approach to Sicily, and were afraid that the Athenians might hereafter make it their head-quarters and proceed against them with a larger force; by the Locrians, for hatred of the people of Rhegium, and with a wish to reduce them by hostilities on both sides.

At the same time too the Locrians had invaded the territory of Rhegium with all their forces, to prevent their going to the rescue of Messana, and also at the instigation of some exiles from Rhegium who were with them. For that town had been for a long time torn by faction, and it was impossible at the present time to resist the Locrians; for which reason they were the more determined to attack them.

After devastating the country, the Locrians retired with their land-forces, but their ships remained to guard Messana; and others that were being manned were to go to that station, and carry on the war from it.

About the same period of the spring, before the corn was ripe, the Peloponnesians and their allies made an incursion into Attica, under the conduct of Agis son of Archidamus, king of the Lacedaemonians; and pitching their camp in the country, proceeded to lay it waste.
