In Shakespeare's *Julius Caesar*, Brutus believes that by killing Caesar, they have freed Rome from tyranny. However, Antony is a powerful figure and has a strong following. Brutus knows that a direct confrontation with Antony's forces would be disastrous.
Therefore, Brutus proposes to march to Philippi to meet Antony and Octavius. He believes that the location will give them a strategic advantage and force Antony and Octavius to fight on their terms.
However, this ultimately proves to be a fatal mistake. The battle at Philippi is a decisive victory for Antony and Octavius, leading to Brutus's tragic suicide.
