Fighting here in North Wales (2,11)

I believe the answer is:

at loggerheads

'fighting here' is the definition.
(to be at loggerheads with someone is to fight them)

I can't explain the remainder of the clue.

(Other definitions for at loggerheads that I've seen before include "In confrontation" , "In violent dispute" , "Disagreeing with" , "In violent disagreement" , "Quarrelling" .)

I've seen this clue in The Guardian.
