Aratus remained determined to liberate Argos. In 235 BC he made another attempt, and succeeded in entering the city by attacking at night. But the Argives were once again reluctant to support him, leaving the Achaeans to fight alone. Aratus was wounded in the thigh by a spear. He ordered a retreat, but the timing was unfortunate. The retreat emboldened the tyrant, Aristippus of Argos, who had been preparing to flee the city. Instead, he held his ground and prepared for battle.
