After the assassination, Brutus was approached with a compromise; if Caesar was declared a tyrant, then all of Caesars' appointments to the Senate were null and void. This meant that Brutus would no longer be a Senator and elections would have to be held. Conversely, if he agreed to recognize and honor Caesar's
will, he and the other assassins would be granted
amnesty and retain their positions. Brutus accepted the offer, and Caesar was not declared a tyrant. Part of the offer was that Brutus had to leave Rome, which he did. After leaving Rome, Brutus lived in
Crete from 44 to 42 BC.
In 43 BC, after
Octavian received his
consulship from the Roman Senate, one of his first actions was to have the people that had assassinated Julius Caesar declared
murderers and enemies of the state.
Marcus Tullius Cicero, angry at Octavian, wrote a letter to Brutus explaining that the forces of Octavian and
Mark Antony were divided. Antony had laid siege to the province of
Gaul, where he wanted a governorship. In response to this siege, Octavian rallied his troops and fought a series of battles in which Antony was defeated. Upon hearing that neither Antony nor Octavian had an army big enough to defend Rome, Brutus rallied his troops, which totaled about 17
legions. When Octavian heard that Brutus was on his way to Rome, he made peace with Antony. Their armies, which together totaled about 19 legions, marched to meet Brutus and
Gaius Cassius Longinus. The following battles are known as the
Battle of Philippi. The
First Battle of Philippi was fought on
October 3, 42 BC, in which Brutus defeated Octavian's forces, although Cassius was defeated by Antony's forces. The
Second Battle of Philippi was fought on
October 23, 42 BC and ended in Brutus' defeat.
After the defeat, he fled into the nearby hills with only about four legions. Knowing his army had been defeated and that he would be captured, Brutus committed
suicide. His last words were allegedly "Yes, we must escape, but this time with our hands, not our feet". As a show of respect, Antony covered Brutus' body with a purple garment. Brutus was
cremated, and his ashes were sent to his mother,
Servilia Caepionis. His wife Porcia also committed suicide upon hearing of her husband's death. This is counter to the popular notion provided in
Shakespeare's Julius Caesar, which says Porcia committed suicide prior to Brutus' death.
