After the Battle of Aegospotami the Spartan navy sailed where it pleased unopposed. A fleet of 150 ships entered the Saronic Gulf to impose a blockade on Piraeus. Athens was cut off. In the winter of 404 the Athenians sent a delegation to King Agis at Deceleia proposing to become a Spartan ally if only they would be allowed to keep the walls intact. He sent them on to Sparta. The delegation was turned back on the road by the ephors. After hearing the terms they suggested the Athenians return with better ones.
