The Battle of Xiphard Base ultimately did not lead to the massive losses that the Larkinson Clan had feared.
With much of its defenses and secret weapons crippled, the Crona Lords stood no chance against the Penitent Sisters. Their mechs, despite outnumbering the second-class mechs by five-to-one, only served to give the exiled Hexers more exercise.
The mech pilots of the Crona Lords mostly died in vain. Their feeble attacks did not cross the threshold that allowed them to overcome the superior armor of their opponents.
Certainly, with quantity they might have been able to circle around and attack the weak points of the Penitent Sister mechs, but they needed at least twice or thrice as much mechs to pull off such a plan.
