Aratus' soldiers scaled the walls of the citadel and the garrison surrendered. By dawn, the Achaeans held both citadel and city, in a victory owing partly to luck but also to good planning and nerve. The storming of the near-impregnable Acrocorinth was another major accomplishment for Aratus, following his taking of Sicyon. Very few achieved the feat; among those who did was Demetrius I, "the Besieger". Aratus went on to capture Lechaeum, the harbour of Corinth, and secure the 25 Macedonian warships docked there. He garrisoned the captured citadel with 400 Achaeans and 50 watchdogs.
