Hordeonius Flaccus
Marcus Hordeonius Flaccus (c. 14 – 69 AD) was a Roman senator. He was consul in 47, and commander of the Rhine army during the Batavian rebellion.
In 69, the year of the four emperors, Emperor Vitellius ordered troops from the Rhine borders redeployed to Italy to support him against the rebellion of Vespasian which Flaccus refused because he had heard rumors of a possible uprising of the Batavians. When Vittellius ordered forced recruitment of Batavians, they did rise in rebellion against the Romans.
His indecision in which emperor to support (Vitellius or Vespasian), and his resulting inactivity in the containment of the Batavian rebellion, made his later reputation suffer in the works of Tacitus. He was murdered by his own troops (still loyal to Vitellius) after trying to celebrate the victory of Vespasian.
