More from LLPSI Capitoluim XLII (Exercitium 11) where Orberg is testing on use of Gerundive - this is question 3:

Aborigines ad arcendam vim advenarum concurrunt.

The indigenous inhabitants ran to prevent the power of the new invaders.

ad arcendam vim is gerundive expressing purpose.

Am I right in taking it that the vim here is the vim of the advenarum?

You’re right.

I might translate arcendam as “ward off” or “defend against”, and vim as “force.”

“The natives rushed to defend against the force of the newcomers.”
