octavian (later known as augustus) and mark antony soon arrived. cassius planned to starve them out, by using his superior position in the country. however, they were forced into a pair of battles by antony, in the battle of philippi. brutus was successful against octavian, and took his camp. cassius, however, was defeated and overrun by antony. cassius, unaware of brutus' victory, committed suicide. he was mourned by brutus as "the last of the romans". brutus, like octavian, was not an experienced military commander and, ten days later, antony completed the victory. brutus also committed suicide.
