The commissioners, however, were slow in coming; so that both Diaeus and Menalchidas had time to misrepresent the Senate’s answer to their respective peoples. The Achaeans believed that they had full leave to proceed according to the league law against the Spartans; the Spartans believed that they had permission to break off from the league. Once more, therefore, war was on the point of breaking out.[42] Just at this time Q. Caecilius Metellus was in Macedonia with an army to crush Andriscus. He was sending some commissioners to Asia, and ordered them to visit the Peloponnese on their way and give a friendly warning. It was neglected, and the Spartans sustained a defeat, which irritated them without crushing their revolt. When Diaeus succeeded Damocritus as Strategus in B.C. 147, he answered a second embassy from Metellus by a promise not to take any hostile steps until the Roman commissioners arrived. But he irritated the Spartans by putting garrisons into some forts which commanded Laconia; and they actually elected Menalchidas as a Strategus in opposition to Diaeus. But finding that he had no chance of success Menalchidas poisoned himself.[43] Then followed the riot at Corinth.[44] Marcus Aurelius Orestes at the head of a commission arrived at last at Corinth, and there informed the magistrates in council that the league must give up Argos, Corinth, and Sparta. The magistrates hastily summoned an assembly and announced the message from the Senate; a furious riot followed, every man in Corinth suspected of being a Spartan was seized and thrown into prison; the very residence of the Roman commissioners was not able to afford such persons any protection, and even the persons of Orestes and his colleagues were in imminent danger. Some months afterwards a second commission arrived headed by Sextus Julius Caesar, and demanded, without any express menace, that the authors of the riot should be given up. The demand was evaded; and when Caesar returned to Rome with his report, war was at once declared. [Sidenote: B.C. 147-146.]
