 Titus Manlius' reputation grew on account of his filially pious actions, which helped him to be elected as a military tribune later in the year.In 361 BC, Titus Manlius fought in the army of Titus Quinctius Poenus Capitolinus Crispinus against the Gauls during the Battle of the Anio River.When a Gaul of enormous size and strength challenged the Romans to single combat, Manlius accepted the challenge with the approval of Poenus after the rest of the army had held back from responding for a long period of time.
