Blunder from English soldiers capturing bishop (5)
I believe the answer is:
error
'blunder' is the definition.
(thesaurus)
'english soldiers capturing bishop' is the wordplay.
'english' becomes 'e' (abbreviation).
'soldiers' becomes 'or' (Other Rank).
'capturing' is an insertion indicator.
'bishop' becomes 'rr' (abbreviation for Right Reverend).
'e'+'or'='eor'
'eor' going around 'rr' is 'ERROR'.
'from' acts as a link.
(Other definitions for error that I've seen before include "Trial and ___" , "wrongdoing" , "Mistake or mishap" , "1 down" , "Solecism" .)
