Scene of evacuation is done, we hear, at church (7)
I believe the answer is:
dunkirk
'scene of evacuation' is the definition.
'Dunkirk' can be an answer for 'evacuation' (Dunkirk is an example). I am unsure of the 'scene of' bit.
'done we hear at church' is the wordplay.
'we hear' indicates a 'sounds like' (homophone) clue.
'at' says to put letters next to each other.
'church' becomes 'kirk' (kirk is a kind of church).
'done' is a homophone of 'dun'.
'dun'+'kirk'='DUNKIRK'
'is' is the link.
Can you help me to learn more?
(Other definitions for dunkirk that I've seen before include "Crisis where a desperate effort is the only alternative to defeat?" , "Site of nineteen forty nine Allied evacuation" , "French port, scene of a 1940 Allied evacuation" , "Withdrawal" , "French seaport from which British troops were evacuated in 1940" .)
