As the title says, this is about being a Frank, Alemanni, Saxon, or Vandal in the 355 campaign.
Now, I just got back to this game after a break of a while, and having remembered that I had tried both Roman factions and the Lakhmid Arabs, I decided on something different.
Now, I remember how hectic, difficult, and chaotic it was to play as Julian during this campaign, and it is not much different as a Alemannian! I quickly organized my army and went after the two cities of Augustus, which I forced the Romans into giving me via treaty.
Yet the same turn I ambushed a Roman army with my faction leader and destroyed them. I have now decided on a plan of setting my major forces along the roads which the major Roman armies will travel, thereby negating their superior troops.
It is working, I am about to give battle again on my own terms!
