One chap’s rival wins fresh conflict (7,5,3)

I believe the answer is:

spanish civil war

'conflict' is the definition.
(1930s conflict)

'one chap's rival wins fresh' is the wordplay.
'one' becomes 'i' (Roman numeral).
'fresh' is an anagram indicator.
'i'+'chaps'+'rival'+'wins'='ichapsrivalwins'
'ichapsrivalwins' is an anagram of 'SPANISH CIVIL WAR'.

I've seen this clue in The Times.
