From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
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. Thus while the fleet of Attalus went home and the Rhodian fleet remained temporarily at Chios, Philip, who falsely ascribed the victory to himself, was able to continue his voyage and to turn towards Samos, in order to occupy the Carian towns.
On the Carian coast the Rhodians, not on this occasion supported by Attalus, gave battle for the second time to the Macedonian fleet under Heraclides, near the little island of Lade in front of the port of Miletus. The victory, claimed again by both sides, appears to have been this time gained by the Macedonians; for while the Rhodians retreated to Myndus and thence to Cos, the Macedonians occupied Miletus, and a squadron under Dicaearchus the Aetolian occupied the Cyclades.
