Hawks wine round hospital showing war damage (5,5)
I believe the answer is:
shell shock
'war damage' is the definition.
(psychological condition caused by war)
'hawks wine round hospital' is the wordplay.
'hawks' becomes 'sells' (I've seen this in another clue).
'wine' becomes 'hock' (hock is a kind of wine).
'round' indicates putting letters inside.
'hospital' becomes 'h' (abbreviation for hospital on maps).
'sells'+'hock'='sellshock'
'sellshock' going around 'h' is 'SHELL-SHOCK'.
'showing' acts as a link.
(Other definitions for shell shock that I've seen before include "it disabled soldiers" , "Mental disturbance due to battle experiences" , "Soldier's trauma" , "it's psychologically damaging" , "Wartime ailment" .)
