theology. Although Caesar is one of the few primary sources on the Druids, many believe that he had used his influence to portray the Druids to the Roman people as both barbaric, as they performed human sacrifices, and civilized in order to depict the Druids as a society worth assimilating to Rome (DBG 6.16). Vorenus and Pullo Lucius Vorenus and Titus Pullo were two centurions in the garrison of Quintus Tullius Cicero, brother of Marcus Tullius Cicero, and are mentioned in Book 5.44 of De Bello Gallico. They were bitter rivals who both sought to achieve the greatest honors "and every year used to contend for promotion with the utmost animosity" [] (DBG 5.44).

They showed their prowess during this siege by jumping from the wall and directly into the enemy despite being completely outnumbered. During the fighting, they both find themselves in difficult positions and are forced to save each other, first Vorenus saving Pullo and then Pullo saving Vorenus.

Furthermore, the tale of unity on the battlefield between two personal rivals is in direct opposition to the disunity of Sabinus and Cotta, which resulted in the destruction of an entire legion.

Thus, Caesar turns a military blunder into a positive propaganda story. Hostage exchanges In the first two books of De Bello Gallico, there are seven examples of hostage exchanges. First, the Helveti exchange hostages with the Sequani as a promise that the Sequani will let the Helveti pass and that the Helveti will
