[13] Soon afterwards, Cicero was writing to the governors already stationed there seeking military support to resist Antony's assumption of the provinces; he wrote both to Plancus and Decimus Brutus.
Plancus defended his caution with the argument that declaring too rashly before preparations would have meant swift consequences like those that befell Decimus Brutus (then besieged in Mutina).
Pedius' passage of the lex Pedia which sentenced the tyrannicides to exile in absentia changed Plancus' calculations; after a few months of cooperation with Decimus, he broke off.
