In 42 BCE, two battles near Philippi in Macedonia ended Brutus and Cassius’s bid to restore the Republic. Marshes, causeways, and camps sprawled beneath an autumn sky. After the second clash, the Liberators’ hopes died with their generals.
What Happened
The Triumvirs ferried armies across the Adriatic, securing bases at Dyrrhachium and then marching along the Egnatian Way toward Philippi. Brutus and Cassius, well-supplied by eastern revenues, chose the ground: plains cut by marsh and a causeway, anchored on hills.
The first battle saw Cassius overrun on his left while Brutus pushed back Octavian on the right. Confusion and dust the color of ash cloaked the field; Cassius, misinformed, took his own life, thinking Brutus defeated. The camps steadied; both sides dug in behind earthen ramparts.
Weeks later, hunger and foraging pressures forced decision. The second battle broke Brutus’s line; Antony’s men pressed through a gap while Octavian’s recovered. Bronze shields clashed; pila thudded into wicker screens along the ramparts; the marsh water turned murky with churned soil.
Brutus fled to the hills and, facing encirclement, died by his own hand. Macedonian breezes carried the soft clatter of abandoned armor down to the causeway. The Liberators’ war was over; the Republic had no generals left to lead its idea.
Why This Matters
Philippi liquidated the last organized opposition to the Triumvirs. Antony emerged as the superior field commander; Octavian gained stature and the allegiance of soldiers who had seen him endure defeat and return. The outcome shifted the civil war’s center back to internal division among victors.
The battles also proved how finance and supply shape outcomes. Eastern revenues had sustained Brutus and Cassius for a time, but sea lift and interior lines let Antony and Octavian bring weight to bear. Terrain mattered; logistics decided.
With the assassins gone, the question became which triumvir would own the peace. The answer would be written on Sicilian seas against Sextus Pompey, on Parthia’s frontiers with Antony, and, finally, in the narrow waters off Actium.
