(( I don't remember claiming that this story had anything to DO with Sweden...this is taking place in Britannia, in 121 AD...A battle is taking place between Briton Celts, and the Local Roman Legion.
Also WJ, I hate to be nit-picky, but they wouldn't move to attack you. They are in a shield wall, a defensive formation, they don't run to attack others.
Javelins, arrows, and firepots ( Oh my! ) continued to rain down on the Barbarians as they continued there charge. Men were set ablaze, impaled, and stabbed as they battered against the Auxilia's shield wall.
The Auxilian shield wall had began to develop a few weak points in it, however, which if not taken care of, could cause it to buckle eventually.
