In the Battle of Naulochus, Marcus Vipsanius Agrippa, admiral of Octavian, defeats Sextus Pompey, son of Pompey, thus ending Pompeian resistance to the Second Triumvirate.

The naval Battle of Naulochus was fought on 3 September 36 BC between the fleets of Sextus Pompeius and Marcus Vipsanius Agrippa, off Naulochus, Sicily. The victory of Agrippa, admiral of Octavian, marked the end of the Pompeian resistance to the Second Triumvirate.

Marcus Vipsanius Agrippa was a Roman general, statesman and architect who was a close friend, son-in-law and lieutenant to the Roman emperor Augustus. Agrippa is well known for his important military victories, notably the Battle of Actium in 31 BC against the forces of Mark Antony and Cleopatra. He was also responsible for the construction of some of the most notable buildings of his era, including the original Pantheon.

Admiral is one of the highest ranks in many navies. In the Commonwealth nations and the United States, a "full" admiral is equivalent to a "full" general in the army or the air force. Admiral is ranked above vice admiral and below admiral of the fleet, or fleet admiral.

Gaius Julius Caesar Augustus, also known as Octavian, was the founder of the Roman Empire, who reigned as the first Roman emperor from 27 BC until his death in AD 14. The reign of Augustus initiated an imperial cult and an era of imperial peace in which the Roman world was largely free of armed conflict. The Principate system of government was established during his reign and lasted until the Crisis of the Third Century.

Sextus Pompeius Magnus Pius, also known in English as Sextus Pompey, was a Roman military leader who, throughout his life, upheld the cause of his father, Pompey the Great, against Julius Caesar and his supporters during the last civil wars of the Roman Republic.
