Publius Crassus
Caesar is compelled to modify his assessment of the situation when he writes his account of the third year of the war, in which he himself plays a diminished role and which is markedly shorter than his other six books. Instead, Book 3 of the "Bellum Gallicum" focuses on Sulpicius Galba’s travails in the Alps, and campaigns led by the two junior officers Publius Crassus and Decimus Brutus.
