Antony's association with Publius Clodius Pulcher allowed him to achieve greater prominence. Clodius, through the influence of his benefactor Marcus Licinius Crassus, had developed a positive political relationship with Julius Caesar. Clodius secured Antony a position on Caesar's military staff in 54 BC, joining his conquest of Gaul. Serving under Caesar, Antony demonstrated excellent military leadership. Despite a temporary alienation later in life, Antony and Caesar developed friendly relations which would continue until Caesar's assassination in 44 BC. Caesar's influence secured greater political advancement for Antony. After a year of service in Gaul, Caesar dispatched Antony to Rome to formally begin his political career, receiving election as quaestor for 52 BC as a member of the Populares faction. Assigned to assist Caesar, Antony returned to Gaul and commanded Caesar's cavalry during his victory at the Battle of Alesia against the Gallic chieftain Vercingetorix. Following his year in office, Antony was promoted by Caesar to the rank of Legate and assigned command of two legions (approximately 7,500 total soldiers).
