One army shattered: are there others? (3,4)
I believe the answer is:
any more
'are there others?' is the definition.
('any more?' can mean 'are there others?')
'one army shattered' is the wordplay.
'shattered' indicates anagramming the letters.
'one'+'army'='onearmy'
'onearmy' with letters rearranged gives 'ANY MORE'.
(Other definitions for any more that I've seen before include "Still further" , "'Annie doesn't live here - - '" .)
