Caesar's Civil War In 49 BC, when Julius Caesar crossed the Rubicon and ignited the Civil War, Sulla chose to support him against the Senate. Given a command in the Caesarian army, Sulla accompanied Caesar on his campaign in Greece against Pompey. At Dyrrachium, Sulla was left in charge of Caesar's camp and successfully repulsed a Pompeian attack which broke through the fortifications while the bulk of the army was elsewhere fighting with Caesar. Upon driving the Pompeians back, Sulla determined not to pursue and instead withdrew back to the camp. Caesar remarks in his commentaries that if Sulla had instead pursued the fleeing enemy and followed up on his victory, the entire Civil War might have been ended on that day. However, he does not blame Sulla's cautious conduct or his decision to stay in the camp, which was his responsibility to protect. Sulla commanded the right wing of Caesar's army at the Battle of Pharsalus. In the battle, the Caesarians were victorious and the defeated Pompey fled to Egypt, where he was murdered. Publius Cornelius Sulla died in 45 BC. References 45 BC deaths Publius 1st-century BC Roman generals 1st-century BC Roman praetors Roman patricians Year of birth unknown
