Answer:
Brutus' decision to move forward to meet the enemy forces halfway so as not to lose the support of the Philippians who have been forcefully put under their authority.
Step-by-step explanation:
Quoted from William Shakespeare's tragedy play "Julius Caesar", these lines are said by Brutus in Act IV scene III. In these lines, Brutus is in discussion on how best to tackle the upcoming armies of Antony and Octavius.
After the death of Julius Caesar and the fight for power of Rome started, Brutus and Cassius have fled from Rome and are fighting the triumvirate- Antony, Octavius and Lepidus for the right to rule over Rome. The quote in the question is when Brutus suggest they march towards Philippi so that they will meet the enemy halfway, or they will lose their support from the people of Philippi who, ironically, were forcefully put under their own power. So, in the midst of their ever want of being free from the clutches of Brutus and Cassius, Brutus thinks it's best to be there and not further add to the advantage of the Philippians to break free from them and join the army of the Triumvirate.
