The Battle of the Eclipse[2] (or Battle of Halys)[3] was fought in the early 6th century BCE in Anatolia (present-day Turkey) between the Medes and the Lydians. According to ancient Greek historian Herodotus, the battle was interrupted by "day turning into night" – presumably a solar eclipse – and the result was a draw which led to both parties negotiating a peace treaty and ending a six-year war.
