who had charge of his elephants, stood firm until Pyrrhus's troops surrounded them, whereupon they surrendered both themselves and the elephants. Pyrrhus now chased after the rest of Antigonus's army which, demoralised by its earlier defeat, declined to fight. As the two armies faced each other, Pyrrhus called out to the various officers by name and persuaded the whole body of infantry to desert. Antigonus escaped by concealing his identity. Pyrrhus now took control of upper Macedonia and Thessaly, while Antigonus held on to the coastal towns. But Pyrrhus now wasted his victory. Taking possession of Aegae, the ancient capital of Macedonia, he installed a garrison of Gauls, who greatly offended the Macedonians by digging up the tombs of their kings and leaving the bones scattered about as they searched for gold. He also neglected to finish off his enemy. Leaving him in control of the coastal cities, he contented himself with insults. He called Antigonus a shameless man for still wearing the purple, but he did little to destroy the remnants of his power. Before this campaign was finished, Pyrrhus had embarked upon a new one. In 272 BC, Cleonymus, an important Spartan, invited him to invade Laconia. Gathering an army of twenty-five thousand foot, two thousand horse, and twenty-four elephants, he crossed over to the Peloponnese and occupied Megalopolis in Arcadia. Antigonus, after reoccupying part of Macedonia, gathered what forces he could and sailed to Greece to oppose him. As a large part of the Spartan army led by king Areus was in Crete at the time, Pyrrhus besieged Sparta with great hopes of taking the city easily, but the citizens organized stout resistance, allowing one of Antigonus's commanders, Aminias the Phocian, to reach the city with a force of mercenaries from Corinth. Soon after this, the Spartan king, Areus, returned from Crete with 2,000 men. These reinforcements stiffened resistance, and Pyrrhus, finding that he was losing men to desertion every day, broke off the attack and started to plunder the country. The most important Peloponnesian city after Sparta was Argos. The two chief men, Aristippus and Aristeas, were keen rivals. As Aristippus was an ally of Antigonus, Aristeas invited Pyrrhus to come to Argos to help him take over the city. Antigonus, aware that Pyrrhus was advancing on Argos, marched his army there as well, taking up a strong position on some high ground near the city.
