'dispute' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'or ban low gear manoeuvres?' is the wordplay.
'manoeuvres?' indicates an anagram (I've seen 'manoeuvring' mean this).
'or'+'ban'+'low'+'gear'='orbanlowgear'
'orbanlowgear' is an anagram of 'ANGLO-BOER WAR'.
