At which 48 BC battle did Pompey defeat Caesar before Pharsalus? He defeated Caesar at Dyrrhachium.

The Battle of Dyrrhachium, fought near modern Durrës in Albania during Caesar’s civil war, was a Pompeian victory in 48 BC. Caesar had tried to seize the important port and supply center, but Pompey reached it first and established a strong position protected by the sea and surrounding heights.

Caesar then built extensive fortifications around Pompey’s camp, attempting to cut off supplies and force a surrender. Pompey answered with his own defensive works. After months of siege warfare and skirmishing, Pompey broke through Caesar’s lines. Caesar attacked a newly occupied position but was repulsed and withdrew toward Apollonia and then Thessaly.

Dyrrhachium was serious but not decisive. Pompey’s army had won the field, yet Pompey did not immediately destroy Caesar’s weakened force. He pursued him toward Thessaly, where the two armies met at Pharsalus. There, on 9 August 48 BC, Caesar won the much more famous and strategically decisive battle.
