When talking about Caesar going to Hispania many sites are pretty sure about his forces....like this for an example..."Caesar crossed the Rhône and the Pyrenees with the legions VI, VII, VIIII, X, XI, XIV", but I searched the ancient sources and couldn't find so many clues. Maybe I'm missing something. As far as I know he had 3 legions in Narbo, 3 were with him at Massilia (where did he got those?!) and others (no number or location here) from Gaul had orders to follow as fast as they can.
