Caught on battlefield, in the soup (8)
I believe the answer is:
consomme
'soup' is the definition.
(consomme is a kind of soup)
'caught on battlefield' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'battlefield' becomes 'somme' (I've seen this before).
'c'+'on'+'somme'='CONSOMME'
'in the' is the link.
(Other definitions for consomme that I've seen before include "Clear soup made with concentrated stock" , "liquid course" , "starter course" , "Clear initial course" , "Clear soup usually of beef, veal or chicken" .)
