Cassius Dio's accounts reveal a different perspective on Caesar's bravery and leadership from the one portrayed by Caesar himself. While Caesar's soldiers were either mutinous or terrified, he was able to "rally those troops" and lead them against the German leader, Ariovistus, according to his self-described accounts.
Cassius Dio and other historians offer alternative interpretations of Caesar's motives and actions in his military campaigns in Gaul, including portraying the Roman soldiers as reluctant pawns in Caesar's career ambitions rather than fearless warriors ready for battle.
Caesar's ability to rally troops and put them in a state of mind where they could face Germany's leader speaks volumes about the man that Caesar really was.
