But the Rhodo-Pergamene fleet followed him, and forced him to accept battle in the straits of Chios.

The number of the Macedonian decked vessels was smaller, but the multitude of their open boats made up for this inequality, and the soldiers of Philip fought with great courage.
But he was at length defeated.

Almost half of his decked vessels, 24 sail, were sunk or taken; 6000 Macedonian sailors and 3000 soldiers perished, amongst whom was the admiral Democrates; 2000 were taken prisoners.

The victory cost the allies no more than 800 men and six vessels.

But, of the leaders of the allies, Attalus had been cut off from his fleet and compelled to let his own vessel run aground at Erythrae; and Theophiliscus of Rhodes, whose public spirit had decided the question of war and whose valour had decided the battle, died on the day after it of his wounds.
