Is there a word for the act of subduing something?

I'm referring to military forces subduing another group of military forces. Subduction is what I initially thought of but that specifically refers to the geological process involving tectonic plates. I'm trying to say that "the ... (act of subduing) the x guard was legitimate and legal" but was hoping for a word (like subduction except it doesn't mean what I want it to mean) instead of a phrase. Thank you!


Solution 1:

I think you have answered your own question:

I'm trying to say that "the ... (act of subduing) the x guard was legitimate and legal"

Subduing

"The subduing of the x guard was legitimate and legal."

In that sentence, "subduing" acts as a verbal noun.

Or

"Subduing the x guard was legitimate and legal."

In that sentence, "subduing" acts as a gerund.

Both express the action of their verb.
