フィリッピの戦い
Claudianus became a supporter of Brutus and Cassius and joined them in the war against Octavian and Mark Antony. The decision would have serious consequences for him and for Livia's family. He fought alongside Brutus and Cassius at the Battle of Philippi in 42 BC. When Brutus and Cassius were defeated, they committed suicide. Claudianus killed himself in his tent to avoid being captured alive by the victors.
