Here's the issue, Charlemagne lived more 700 years after Cesar. The Franks under Charlemagne used different fighting tatics the the Gauls Caesar fought. Caesar will have next to know information on the Franks from Charlemagne time, who I'd also like to point out by the time Charlemagne became king were no longer conisdered Barbarians, and under Charlemagne started to being and end to the Dark Ages with the Carolingian renaissance.
