After Actium, Cleopatra hustled back to Alexandria, and rounded up all of her enemies that she could find and had them executed.
The only time that Cleopatra went to war was in 31 BC at Actium. She lost, big time.
The forces of Octavian (the future Augustus) defeated the combined forced of Mark Antony and Cleopatra VII. Agrippa was the overall commander of Octavian's Fleet. Mark Antony was the overall commander of the Antonine fleet. Cleopatra headed and Egyptian squadron.
The power of Antony and Cleopatra began to erode shortly before the Battle of Actium when many of their allies deserted them. After Actium it was all downhill. Antony's troops began to go over to Octavian and his client king allies defected. When Octavian finally entered Alexandria Antony and Cleopatra were totally defeated.
Cleopatra only went to war once and that was at Actium where she and Antony were defeated.
The Battle of Actium took place on September 2, 31 BC, and lasted for approximately eight hours. It was a decisive naval battle between the forces of Octavian (later known as Augustus) and the combined fleet of Mark Antony and Cleopatra.
Cleopatra was in two wars. One against her brother ptolemy XIII and won against him and was a pharoah. Also another one with octavian and lost. She knew if she would go in the streets she would be murdered slowly and painfully. So she committed suicide
Cleopatra first went to war in 31B.C. at Actium. She was also involved in the Alexandrian war, but other than causing it, took no active part in it.
There's no record of Cleopatra ever going on any expeditions. The only traveling she did was for political purposes, such as up the Nile with Caesar, to Rome, to Antioch and to Actium.
Cleopatra did not fight in any battles. Remember, she was a woman and women did not go into combat in the ancient world, except in stories and myths. However Cleopatra was at Actium, but her role there was that of an observer or a nuisance, depending on perception.
Cleopatra engaged in military conflicts primarily alongside Mark Antony against Octavian, the future Emperor Augustus. Their alliance was marked by the famous naval Battle of Actium in 31 BC, where their forces faced defeat. Additionally, Cleopatra's reign saw conflicts with local rivals and challenges to her rule in Egypt, but her most notable war was against Octavian's forces in the context of the larger power struggle in Rome.
Egypt, where he was killed
Egypt never fought against Rome. Cleopatra VII fought alongside Marc Antony in the civil war between Marc Antony and Octavian which would decide which one of them would become the sole ruler of Rome. Most of the forces of Marc Antony and Cleopatra were Roman. They were defeated and committed suicide. Octavian became the sole ruler of Rome and also annexed Egypt.
