You mean Gnaeus Duronius Sejanus? He was from Numidia, IIRC, and won, among other things, the battle of Samarobriva (modern Amiens), where his forces were out numbered by (depending on which historian you believe) either four to one or seven to one.I'm still thinking the 500's. I doubt North Africa is going to fall that easily, and the barbarians are greatly over stretching themselves. Granted, once the Romans lose it, they are out of luck. Well, we HAVE butterflied away some important people. Wasn't that one important general from North Africa?
