Led a Naval Fleet Against Octavian
When Cleopatra and Antony married, it caused quite a few problems for him in Rome, and that was when his ex-brother-in-law decided to stage a coup, leading the Senate to declare war on the new bride. It led to a huge naval battle.
Cleopatra actually led dozens of Egyptian warships alongside Antony, but they were unsuccessful. In fact, the two newlyweds were actually forced to leave Rome and return to Egypt in order to save their own lives.
