As Secundus mustered his forces, he stripped the borders of their much needed garrisons. With the XXI Rapax now marching behind him, he ventured south leaving a very under manned frontier. This of course did not go unnoticed by the local tribes in the area, who crossed the Rhine in force and destroyed two settlements and their garrisons in early april. To add to the insult, the tribes burnt to the ground two auxiliary forts before disappearing back into the dark forests. A relief column sent by Secundus was also ambushed and masscred as it struggled through the marshland to help the beleaguered Rhine settlements,
Secundus was not happy!
