The Second Triumvirate declared this [[civil war]] to avenge Julius Caesar's [[murder]]. The battle consisted of two [[engagement]]s in the [[plain]] west of the ancient city of Philippi. The first occurred on the first week of October; Brutus faced Octavian, while Antony's forces were up against those of Cassius. At first, Brutus pushed back Octavian and entered his army's camp. But to the south, Cassius was defeated by Antony, and committed [[suicide]] after hearing a false report that Brutus had also failed. Brutus rallied Cassius' remaining troops and both sides ordered their army to retreat to their camps
