Also, Caracalla perhaps felt more comfortable about campaigning in the upper Main because he was not declaring war on any specific historic tribe, such as the Chatti or Cherusci, against whom Rome had suffered grievous losses.
Måske følte Caracalla sig mere tryg ved at drive krig i øvre Main, eftersom han ikke havde erklæret krig mod nogen bestemt historisk stamme, så som chattere og cheruskere, stammer som Rom havde lidt store tab til.
