I agree that we will probably need a Dictator this year, what with the two wars. It is unlikely that we can finish the Carthaginians this year, with the strength of Hamilcar and the legions required for the ground campaign. The Gauls will be easier to deal with and with a Dictator we have a good chance of getting them off our plate.
So the Assidui propose getting Aemilius back to 15 fleets, and letting him tangle again with Hamilcar as proconsul, while using the rest of our resources to face the Gauls. With 4-6 additional legions and a Dictator/Master of Horse, we should have good odds against the Gauls.
Alternatively, we can recall Aemilius and send a military consul in his place, but I’m not sure there’s a good reason for that. The inability of the navy to meet its goals last year was despite Aemilius’ efforts, not because of them.
