+69.+ Simultaneously with these events the cavalry engagement was also being brought to a decision; in which all the Achaean cavalry, and especially Philopoemen, fought with conspicuous gallantry, for to them it was a contest for freedom. Philopoemen himself had his horse killed under him, and while fighting accordingly on foot received a severe wound through both his thighs. Meanwhile the two kings on the other hill Olympus began by bringing their light-armed troops and mercenaries into action, of which each of them had five thousand. Both the kings and their entire armies had a full view of this action, which was fought with great gallantry on both sides: the charges taking place sometimes in detachments, and at other times along the whole line, and an eager emulation being displayed between the several ranks, and even between individuals. But when Cleomenes saw that his brother’s division was retreating, and that the cavalry in the low ground were on the point of doing the same, alarmed at the prospect of an attack at all points at once, he was compelled to demolish the palisade in his front, and to lead out his whole force in line by one side of his position. A recall was sounded on the bugle for the light-armed troops of both sides, who were on the ground between the two armies: and the phalanxes shouting their war cries, and with spears couched, charged each other. Then a fierce struggle arose: the Macedonians sometimes slowly giving ground and yielding to the superior courage of the soldiers of Sparta, and at another time the Lacedaemonians being forced to give way before the overpowering weight of the Macedonian phalanx. At length Antigonus ordered a charge in close order and in double phalanx; the enormous weight of this peculiar formation proved sufficient to finally dislodge the Lacedaemonians from their strongholds, and they fled in disorder and suffering severely as they went. Cleomenes himself, with a guard of cavalry, effected his retreat to Sparta: but the same night he went down to Gythium, where all preparations for crossing the sea had been made long before in case of mishap, and with his friends sailed to Alexandria. +70.+ Having surprised and taken Sparta, Antigonus treated the citizens with magnanimity and humanity; and after re-establishing their ancient constitution, he left the town in a few days, on receiving intelligence that the Illyrians had invaded Macedonia and were laying waste the country. This was an instance of the fantastic way in which Fortune decides the most important matters. For if Cleomenes had only put off the battle for a few days, or if when he returned to Sparta he had only held out for a brief space of time, he would have saved his crown.
