The destruction of Carthage took place in the spring of B.C. 146. When Scipio went back to celebrate his triumph, Polybius seems to have returned to the Peloponnese, there to witness another act of vengeance on the part of Rome, and to do what he could to lighten the blow to his countrymen, and to preserve the fragments of their shattered liberties.
B.C. 148.
Among the restored Achaean exiles were Diaeus, Damocritus, Alcamenes, Theodectes, and Archicrates. They had returned with feelings embittered by their exile; and without any of the experience of active life, which might have taught them to subordinate their private thirst for revenge to the safety of their country. Callicrates died in B.C. 148, and Diaeus was Strategus in B.C. 149-148, 147-146. The appearance of the pseudo-Philip (Andriscus) in Macedonia, and the continued resistance of Carthage during his first year of office (148), encouraged him perhaps to venture on a course, and to recommend the people to adopt a policy, on which he would otherwise not have ventured. Troubles arising out of a disgraceful money transaction between the Spartan Menalchidas, Achaean Strategus, and the Oropians, who had bribed him to aid them against the Athenians, had led to a violent quarrel with Callicrates, who threatened to impeach him for treason to the league in the course of an embassy to Rome. To save himself he gave half the Oropian money to Diaeus, his successor as Strategus (B.C. 149-148). This led to a popular clamour against Diaeus: who, to save himself, falsely reported that the Senate had granted the Achaeans leave to try and condemn certain Spartans for the offence of occupying a disputed territory. Sparta was prepared to resist in arms, and a war seemed to be on the point of breaking out. Callicrates and Diaeus, however, were sent early in B.C. 148 to place the Achaean case before the Senate, while the Spartans sent Menalchidas. Callicrates died on the road. The Senate heard, therefore, the two sides from Diaeus and Menalchidas, and answered that they would send commissioners to inquire into the case. 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.
B.C. 147.
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.
B.C. 147-146.
The new Strategus, elected in the autumn of B.C. 147, was Critolaus. He was a bitter anti-Romanist like Diaeus: and these statesmen and their party fancied that the Romans, having already two wars on hand, at Carthage and in Spain, would make any sacrifice to keep peace with Achaia. They had not indeed openly declined the demands of Sextus, but, to use Polybius’s expressive phrase, “they accepted with the left hand what the Romans offered with the right.”45 While pretending to be preparing to submit their case to the Senate, they were collecting an army from the cities of the league. Inspired with an inexplicable infatuation, which does not deserve the name of courage, Critolaus even advanced northwards towards Thermopylae, as if he could with his petty force bar the road to the Romans and free Greece. He was encouraged, it was said, by a party at Thebes which had suffered from Rome for its Macedonising policy. But, rash as the march was, it was managed with at least equal imprudence. Instead of occupying Thermopylae, they stopped short of it to besiege Trachinian Heracleia, an old Spartan colony,46 which refused to join the league. While engaged in this, Critolaus heard that Metellus (who wished to anticipate his successor Mummius) was on the march from Macedonia. He beat a hasty retreat to Scarpheia in Locris,47 which was on the road leading to Elateia and the south; here he was overtaken and defeated with considerable slaughter. Critolaus appears not to have fallen on the field; but he was never seen again. He was either lost in some marshes over which he attempted to escape, as Pausanias suggests, or poisoned himself, as Livy says. Diaeus, as his predecessor, became Strategus, and was elected for the following year also. Diaeus exerted himself to collect troops for the defence of Corinth, nominally as being at war with Sparta. He succeeded in getting as many as fourteen thousand infantry and six hundred cavalry, consisting partly of citizens and partly of slaves; and sent four thousand picked men under Alcamenes to hold Megara, while he himself occupied Corinth. When Metellus approached, however, this outpost at Megara hastily retreated into Corinth. Metellus took up his position in the Isthmus, and offered the Achaeans the fairest terms. Diaeus, however, induced them to reject all offers; and Metellus was kept some time encamped before Corinth.
B.C. 146. Arrival of Mummius.
It was now late in the spring of B.C. 146, and the new Consul, Lucius Mummius, arrived at the Roman camp. He at once sent Metellus back to Macedonia, and quietly awaited the arrival of fresh troops, which he had sent for from Crete and Pergamum, as well as from Italy.48 He eventually had an army of about thirty thousand men, nearly double of the Greek army in Corinth. Nothing apparently was done till the late summer, or autumn. But then the final catastrophe was rapid and complete. The Roman officers regarded the Achaean force with such contempt, that they did not take proper precautions, so that Diaeus won a slight advantage against one of the Roman outposts. Flushed with this success, he drew out for a pitched battle, in which he was totally defeated. He made his way to Megalopolis, where, after killing his wife, he poisoned himself.
Polybius saves some statues of national interest.
Thus by a series of imprudent measures, which Polybius denounces, but was not at home to oppose, the Achaean league had drifted into downright war with Rome; and, almost without a struggle, had fallen helplessly at her feet, forced to accept whatever her mercy or contempt might grant. Mercy, however, was to be preceded by stern punishment. Corinth was given up to plunder and to fire, and Polybius returned from Africa in time to witness it.49 The destruction or deportation of works of art, of pictures, statues, and costly furniture, he could not prevent; but he spoke a successful word to preserve the statues of Philopoemen in the various cities from destruction; and also begged successfully for the restoration of some of the Eponymous hero Achaeus, and of Philopoemen and Aratus, which had already been transported as far as Acarnania on their way to Italy.50 He also dissuaded his friends from rushing to take their share in the plunder by purchasing the confiscated goods of Diaeus, which were put to auction and could be bought at low rates; and he refused
