He regarded the Ætolian peasant-league, with its raids and savage feuds, and the revolutionary attempts of the Spartan kings Agis and Cleomenes with equal abhorrence; and by turning his arms against them alternately he played into the hands of the common national foe, Macedonia. As strategus his military talents were of a very inferior order. He was admirably skilled in arranging sudden attacks and ambushes, and in the carrying out of military surprises his boldness and daring were equal to his subtlety and cunning, but as a commander his capacity was small, and in his first campaign he proved diffident, timorous, and faint-hearted. It was not his strong point to look danger boldly in the face, in battle he lost self-control and presence of mind; and he consequently preferred the privy and crooked ways of stratagem, dissimulation, and deceit to a direct and valiant attack.
In his second period of office as strategus, Aratus increased the reputation he had gained by the liberation of Sicyon, but had impaired by a profitless campaign against the Ætolians in the first year of his command, by his successful stratagem at Corinth. With mingled craft and daring he succeeded in ridding the impregnable citadel of Acrocorinthus of its Macedonian garrison, and persuaded this important city, one of the three “fetters of Greece,” to join the League.
ARATUS TAKES CORINTH
Three brothers, Syrian Greeks, had pilfered from the royal treasure at Corinth, and one of them named Erginus, came to Sicyon from time to time to exchange their plunder at the house of a banker well known to Aratus. Through this channel Aratus learned that there was an accessible point in the wall of the citadel; and Erginus, having engaged the concurrence of a fourth brother who served in the garrison, undertook to conduct Aratus to the place, where the wall was no more than fifteen feet high. The brothers demanded a large reward. Sixty talents [£12,000 or $60,000] were to be deposited with the banker, to be paid to them in the event of success; and even in the case of failure, if they escaped, each was to receive a house and a talent. Aratus could not immediately raise so large a sum, and was forced to pledge his plate and his wife’s ornaments, purchasing, as Plutarch observes, the privilege of a perilous adventure for the good of his country, at a price which it would have been accounted magnanimous to reject, if it had been offered as a bribe. When the time came which had been fixed for the attempt, leaving the main body of his forces under arms, he proceeded with four hundred men, few of whom were in the secret, towards Corinth. As they approached the wall, the light of the full moon, which would have rendered concealment almost impossible, was intercepted by clouds which rose from the sea. Several other propitious circumstances contributed to his success, though he fully earned it by his courage. Erginus with seven others, disguised as wayfarers, gained entrance at a gate and overpowered the guard, while Aratus, with only a hundred of his men, scaled the wall, and advanced towards the citadel with the scaling-ladders, ordering the rest to follow. But on his way through the town he fell in with a patrol, one of whom escaped, and soon raised a general alarm.
Aratus, again favoured by the moon which broke through the clouds as he was entangled in the most intricate part of the ascent, reached the wall of the citadel safely, and was soon engaged in a hard combat with the garrison. As soon as the alarm was raised, Archelaus, finding that the citadel was attacked, hastened with all his forces in that direction. But he chanced to light on three hundred Achæans, who, unable to find the track of their comrades, had cowered behind a projection of the rock. They now sprang out as from an ambuscade, and completely routed and dispersed his troops. But they were recalled from the pursuit by Erginus to the succour of Aratus, and their arrival decided the struggle. By sunrise he was in possession of the fortress, and the forces which had followed him from Sicyon, making their appearance at the same time, were joyfully admitted into the lower town by the Corinthians, who helped to capture the royal soldiers.
[242-232 B.C.]
By this act, in which he generously hazarded his private fortune, Aratus gained such a degree of popular confidence that the Achæans thenceforth committed the conduct of public affairs to his hands, and followed his counsel even in the years when he was by law excluded from the office of strategus. The towns of Trœzen, Epidaurus, Cleonæ, and Megara, presently revolted from Macedonia and joined the Achæan League.
