Battle of Cannae - Roman Command

Roman Command

Ordinarily, each of the two consuls would command their own portion of the army, but since the two armies were combined into one, the Roman law required them to alternate their command on a daily basis. It appears that Hannibal had already realized that the command of the Roman army alternated, and planned his strategy accordingly. The traditional account puts Varro in command on the day of the battle, and much of the blame for the defeat has been laid on his shoulders. However, his low origins seem to be exaggerated in the sources, and Varro may have been made a scapegoat by the aristocratic establishment. Varro lacked the powerful descendants that Paullus had: descendants who were willing and able to protect his reputation — most notably, Paullus was the grandfather of Scipio Aemilianus, the patron of Polybius.
