End of serenade — wordless singing — my German is a battle (2,7)
I believe the answer is:
el alamein
'battle' is the definition.
(Second World War battle)
I don't understand how the rest of the clue works.
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" , "North African WW2 battle site" , "victory" , "North African World War two battle" , "WWII battle" .)
