Like the two people you mention, she was patriot.
She wasn't a soldier and probably wasn't even a warrior herself, but the abuse she and her people suffered unjustly drove her to it.
She deserves a statue as much as the other two, Vincingetorix and Arminius.
"She deserves a statue as much as the other two"
Indeed she does.
She did her level best to avenge her husband and daughters.
Any Celtic woman [and most Celtic men] would honor her for that, alone.
She sure as hell doesn't deserve one more than Catavellanus or Caratacus.
