Battle to establish a male line? (2,7)
I believe the answer is:
el alamein
'battle' is the definition.
(Second World War battle)
'establish a male line?' is the wordplay.
'a male line' anagrams to 'EL ALAMEIN'.
Though, I'm not sure how the anagram is indicated.
'to' is the link.
Can you help me to learn more?
(Other definitions for el alamein that I've seen before include "Place in Egypt where Montgomery defeated Rommel" , "WWII battle" , "North African World War two battle" , "North African WW2 battle site" , "victory" .)
