In Italy, the senate at Cicero's urging fought against Antony at the battle of Mutina, where both consuls (Hirtius and Pansa) were killed. During this time, the republicans enjoyed the support of the senate, which confirmed Brutus and Cassius' commands in Macedonia and Syria, respectively. Dolabella switched sides in 43, killing Trebonius in Syria and raising an army against Cassius. Brutus decamped for Syria in early May, writing letters to Cicero criticising Cicero's policy to support Octavian against Antony; at the same time, the senate had declared Antony an enemy of the state. In late May, Lepidus (married to Brutus' half-sister) – possibly forced by his own troops – joined Antony against Cicero, Octavian, and the senate, leading Brutus to write to Cicero asking him to protect both his own and Lepidus' family. The next month, Brutus' wife Porcia died. Cicero's policy of attempting to unify Octavian with the senate against Antony and Lepidus started to fail in May; he requested Brutus to take his forces and march to his aid in Italy in mid-June. It seems that Brutus and Cassius in the east had substantial communications delays and failed to recognise that Antony had not been defeated, contra earlier assurances after Mutina. Over the next few months from June to 19 August, Octavian marched on Rome and forced his election as consul. Shortly afterwards, Octavian and his colleague, Quintus Pedius, passed the lex Pedia making the murder of a dictator retroactively illegal, and convicting Brutus and the assassins in absentia. The new consuls also lifted the senate's decrees against Lepidus and Antony, clearing the way for a general Caesarian rapprochement. Under that law, Decimus was killed in the west some time in autumn, defeating the republican cause in the west; by 27 November 43, the Caesarians had fully settled their differences and passed the lex Titia, forming the Second Triumvirate and instituting a series of brutal proscriptions. The proscriptions claimed many lives, including that of Cicero. When news of the triumvirate and their proscriptions reached Brutus in the east, he marched across the Hellespont into Macedonia to quell rebellion and conquered a number of cities in Thrace. After meeting Cassius in Smyrna in January 42, both generals also went on a campaign through southern Asia minor sacking cities which had aided their enemies. Brutus' depiction among certain authors, like Appian, suffered considerably from this eastern campaign: where Brutus marched
