Aulus understood his orders to make sure he got the attention of the opposing forces when the battle would commence. He left to collect the extra legionaries that the legatus gave to Aulus and he set up his position at the left flank, with the extra legionaries that the legatus provided his legion will have a better chance of using their hit and run strategy to their fullest. 

Aulus went to his men and started to give them a speech "alright legionaries their lies our enemy! they will not stop till they hit your homes, they will try and beat us down and attack our women and our children. Don't let these Carthaginian bastards get through! our strength as a legion will destroy them are you with me!" as the men cheered they got into their positions. the legionnaires got ready as the cavalry were in the front ready to take their full charge and then the legion would follow after them to attack the enemy while the cavalry fell back to charge back into the fray and cause a bigger commotion.
