As for the seven Chian ships that were assisting them in the blockade of the vessels at Peiraeum, they withdrew them, freeing the slaves aboard them and putting the freemen in fetters. And in place of all the ships that had gone away they speedily manned others and sent them to continue the blockade of the Peloponnesians, and it was their intention to man thirty more. Great indeed was their ardour, and there was nothing trivial in their efforts to send out reinforcements against Chios.
Meanwhile Strombichides with his eight ships arrived at Samos; then after taking on an additional Samian ship he sailed to Teos, whose inhabitants he begged to keep quiet. But at this moment Chalcideus bore down upon him, sailing from Chios to Teos with twenty-three ships, and at the same time the land-force of the Clazomenians and Erythraeans was moving along the shore.
Strombichides, however, observed the enemy in time and promptly put out to sea, and when he was in the open sea and saw how numerous were the ships from Chios, he made flight toward Samos; and the enemy pursued him.
As for the land-force, the Teïans would not at first admit them, but when the Athenians fled they brought them into the city. These troops waited for a while, expecting Chalcideus to join them after the pursuit; but when he tarried, they proceeded on their own account to demolish the fort which the Athenians had built on the mainland side of the city of Teos; and in this work they were assisted by a few of the Barbarian troops that had come up, their commander being Stages, a lieutenant of Tissaphernes.
