Biography
Early life
Decimus was probably son of the Roman senator
Decimus Junius Brutus and his notorious wife
Sempronia, one of the participants in the conspiracy of
Catilina in 63 BC. His birthday seems to have been 27 April, and he was probably born in the year 81 BC, perhaps slightly earlier. Decimus was of distinguished ancestry: his father,

, the ill-fated popular reformer. He was also
adopted by a
patrician named Postumius Albinus, one of the last members of the ancient noble house which bore that name. Although some ancient sources accordingly refer to Decimus as 'Albinus', and the name also appears on some coins he himself minted, Decimus does not seem to have changed his name to reflect the adoption, as was customary, and his contemporaries continued referring to him by his birth name, even in official contexts.

Veneti in 56 BC. In the decisive
Battle of Morbihan, Decimus Brutus succeeded in destroying the Veneti's fleet. Using sickle-like hooks fitted on long poles, Decimus Brutus attacked the enemy's sails, leaving them immobilized and easy prey to Roman boarding parties. He also served against

When the
Republican Civil War broke out, Decimus Brutus sided with his commander, Caesar, and was entrusted once again with fleet operations.
Richard Billows argued that Caesar loved Decimus Brutus almost as a son. In 50 BC he married Paula Valeria, the sister of
Gaius Valerius Triarius, a friend of Cicero who later fought alongside Pompey at Pharsalus.

Defeating Decimus Brutus was a way for Antony to regain his ascendancy and get control of the strategically important Italian Gaul; while conversely Cicero encouraged the former to destroy Antony and thereby restore the commonwealth.
In 43 BC Decimus Brutus occupied Mutina, laying in provisions for a protracted siege. Antony obliged him, and blockaded Decimus Brutus' forces, intent on starving them out.

circumvallation as Vercingetorix had done to Caesar at

With the siege raised, Decimus Brutus cautiously thanked Octavian, now commander of the legions that had rescued him, from the other side of the river. Octavian coldly indicated he had come to oppose Antony, not aid Caesar's murderers. Decimus Brutus was given the command to wage war against Antony, but many of his soldiers deserted to Octavian.

With Cicero's support, however, Decimus Brutus crossed the Alps to join
Plancus in the war against Antony; but when Plancus switched sides his position became untenable and he was forced to flee. He attempted to reach
