Thucydides, History of the Peloponnesian War

57. Before the Athenian ships had actually touched, the Aeginetans quitted a fort on the seashore¹ which they were just building and retired to the upper city, where they lived, a distance of rather more than a mile. [2] One of the country garrisons of the Lacedaemonians which was helping to build the fort was entreated by the Aeginetans to enter the walls, but refused, thinking that to be shut up inside them would be too dangerous. So they ascended to the high ground, and then, considering the enemy to be more than a match for them, would not come down. [3] Meanwhile the Athenians landed, marched straight upon Thyrea with their whole army, and took it. They burnt and plundered the city, and carried away with them to Athens all the Aeginetans who had not fallen in the battle, and the Lacedaemonian governor of the place, Tantalus the son of Patrocles, who had been wounded and taken prisoner. [4] They also had on board a few of the inhabitants of Cythera, whose removal seemed to be required as a measure of precaution. These the Athenians determined to deposit in some of the islands; at the same time they allowed the other Cytherians to live in their own country, paying a tribute of four talents². They resolved to kill all the Aeginetans whom they had taken in satisfaction of their long-standing hatred, and to put Tantalus in chains along with the captives from Sphacteria.
