battle of Adrianople

The second Battle of Adrianople (August 9, 378), sometimes known as the Battle of Hadrianopolis, was fought between a Roman army led by the Roman Emperor Valens and Gothic rebels (largely Thervings as well as Greutungs, non-Gothic Alans, and various local rebels) led by Fritigern. The battle took place about 8 miles or 13 kilometers north of Adrianople (modern Edirne in European Turkey, near the border with Greece and Bulgaria) in the Roman province of Thracia and ended with an overwhelming victory for the Goths.
