The meaning of てくれん in 「アギマの領地を削り取ってくれん」

Question

I came across this line recently and don't know how to interpret it. For context, the speaker is the commander of a foreign army and his forces have just met those of the アギマ王国 on the battlefield. He says this line to the アギマ army's commander before the battle.

ついに追い詰めたぞ！この度こそワシが勝利し、アギマの領地を削り取ってくれん！

I initially assumed くれん was the shortened form of 呉れない but that doesn't make much sense, does it? Could someone explain what くれん is doing here?

Answer 1

This is a combination of the followings:

1. "Arrogant and derogatory くれる", used when the speaker does something bad to others or when someone does something bad to the speaker

   • Why is くれる used here and not あげる (see the third example)
   • Using くれる for doing something bad

2. Archaic volitional auxiliary む, which is also written as ん

   • archaic -an conjugation
   • What is the verb ending of われん mean?

So 削り取ってくれん is an even more pompous/arrogant/old-fashioned version of 削り取ってくれよう or 削り取ってやろう (This やる is used in the second sense here.)
