In the months following these events, Thrasybulus commanded the Athenian fleet in several major engagements. At the Battle of Cynossema, he commanded one wing of the fleet and prevented Athenian defeat by extending his flank to prevent encirclement; the battle ended in Athenian victory. Shortly afterwards Thrasybulus again commanded a wing of the Athenian fleet at Abydos, another Athenian victory.
