immunity. He also records that he owned gold mines at Scapte Hyle (literally "Dug Woodland"), a coastal area in Thrace, opposite the island of Thasos. Because of his influence in the Thracian region, Thucydides wrote, he was sent as a strategos (general) to Thasos in 424 BC. During the winter of 424–423 BC, the Spartan general Brasidas attacked Amphipolis, a half-day's sail west from Thasos on the Thracian coast, sparking the Battle of Amphipolis. Eucles, the Athenian commander at Amphipolis, sent to Thucydides for help. Brasidas, aware of the presence of Thucydides on Thasos and his influence with the people of Amphipolis, and afraid of help arriving by sea, acted quickly to offer moderate terms to the Amphipolitans for their surrender, which they accepted. Thus, when Thucydides arrived, Amphipolis was already under Spartan control. Amphipolis was of considerable strategic importance, and news of its fall caused great consternation in Athens. It was blamed on Thucydides, although he claimed that it was not his fault and that he had simply been unable to reach it in time. Because of his failure to save Amphipolis, he was exiled: I lived through the whole of it, being of an age to comprehend events, and giving my attention to them in order to know the exact truth about them. It was also my fate to be an exile from my country for twenty years after my command at Amphipolis; and being present with both parties, and more especially with the Peloponnesians by reason of my exile, I had leisure to observe affairs somewhat particularly. Using his status as an exile from Athens to travel freely among the Peloponnesian allies, he was able to view the war from the perspective of both sides. Thucydides claimed that he began writing his history as soon as the war broke out, because he thought it would be one of the greatest wars waged among the Greeks in terms of scale:Thucydides, an Athenian, wrote the history of the war between the Peloponnesians and the Athenians, beginning at the moment that it broke out, and believing that it would be a great war, and more worthy of relation than any that had preceded it.This is all that Thucydides wrote about his own life, but a few other facts are available from reliable contemporary sources. Herodotus wrote that the name Olorus, Thucydides's father's name, was connected with Thrace and Thracian royalty.
