If you actually read the de bello gallico you would have a quite different opinion. Julius Caesar avoided battle and military confrontation as much as he could and usually the armies he had available for his campaigns were a fraction of the size of the armies he was confronting.<p>Edit: it is also worth adding that Julius Caesar was regularly agreeing to peace agreements with surrounding tribes and populations. Yet, many of his military activities had to be swiftly planned to reject surprise attacks by those same tribes and populations that had been asking for the peace agreements in the first place.
