History of the Peloponnesian War

Meanwhile, the Locrians had invaded the Rhegian territory with all their forces, to prevent their succoring Messina, and also at the instance of some exiles from Rhegium who were with them; the long factions by which that town had been torn rendering it for the moment incapable of resistance, and thus furnishing an additional temptation to the invaders.

After devastating the country the Locrian land forces retired, their ships remaining to guard Messina, while others were being manned for the same destination to carry on the war from thence.

About the same time in the spring, before the corn was ripe, the Peloponnesians and their allies invaded Attica under Agis, the son of Archidamus, king of the Lacedaemonians, and sat down and laid waste the country.
