reached the Peloponnesus. Metellus sought by the utmost moderation
to induce the Greeks to abandon their senseless resistance, and gave
orders, for example, that all the Thebans with a single exception,
should be allowed their liberty; his well-meant endeavours were
thwarted not by the energy of the people, but by the desperation of
the leaders apprehensive for their own safety. Diaeus, who after
the fall of Critolaus had resumed the chief command, summoned all men
capable of bearing arms to the isthmus, and ordered 12,000 slaves,
natives of Greece, to be enrolled in the army; the rich were applied
to for advances, and the ranks of the friends of peace, so far as they
did not purchase their lives by bribing the ruling agents in this reign
of terror, were thinned by bloody prosecutions. The war accordingly was
continued, and after the same style. The Achaean vanguard, which, 4000
strong, was stationed under Alcamenes at Megara, dispersed as soon as
it saw the Roman standards. Metellus was just about to order an
attack upon the main force on the isthmus, when the consul Lucius
Mummius with a few attendants arrived at the Roman head-quarters
and took the command. Meanwhile the Achaeans, emboldened by a
successful attack on the too incautious Roman outposts, offered
battle to the Roman army, which was about twice as strong, at
Leucopetra on the isthmus. The Romans were not slow to accept it.
At the very first the Achaean horsemen broke off en masse before the
Roman cavalry of six times their strength; the hoplites withstood the
enemy till a flank attack by the Roman select corps brought confusion
also into their ranks. This terminated the resistance. Diaeus fled
to his home, put his wife to death, and took poison himself. All the
cities submitted without opposition; and even the impregnable Corinth,
into which Mummius for three days hesitated to enter because he
feared an ambush, was occupied by the Romans without a blow.
