Sense a battle with European head (9)

I believe the answer is:

awareness

I'm a little stuck... Click here to teach me more about this clue!

'sense' is the definition.
(thesaurus)

'a battle with european head' is the wordplay.
'battle with' becomes 'war' (I've seen this before. I am not sure about the 'with' bit.).
'european' becomes 'E' (abbreviation e.g. EU).
'head' becomes 'ness' (ness is a headland).
'a'+'war'+'e'+'ness'='AWARENESS'

Can you help me to learn more?

(Other definitions for awareness that I've seen before include "Knowing" , "Perception" , "Grasp" , "Consciousness,knowingness" , "Knowledge (of a fact)" .)

I've seen this clue in The Telegraph.
