Hi all, I'm doing a research question on the battle of Cannae and whether or not after the battle should Hannibal have marched for Rome. I do have some idea of what happened during and after the battle which would help my arguments but do you guys have any other advice of what to do?

heres what i know (pretty sure i know more but cant think right now and need guidance):

• Hannibal destroyed Rome's army, so lot of Roman casualties

• some of the allies kinda defected? not sure what word to use

• one of the greatest military battles but huge disappointment history wise for rome

• afterwards Rome was like panicing cause they got defeated and loss allies = less numbers for their armies ( this is after the latin alliance citizenship thing where they make other states give troops right?)

• battle led to the change and reformation of the Roman army

• something happened and Carthage stopped supporting Hannibal (guess this means lack of resources to march upon rome)

• at some point after the battle Hannibal did march upon Rome but was unsuccessful

• this was during the second punic war

• read somewhere forgot where that Hannibal was like exiled

• Roman battle formation was so bad that it was why they lost the battle

i apologise in advanced for the shitty grammar i have been awake since 5:30 am on Wednesday and now its 1:40 am on Thursday.
