Attorney General attending trial, battle ensuing (9)
I believe the answer is:
agincourt
'attorney general attending trial battle ensuing' is the definition.
I can't judge whether this defines the answer.
'attorney general attending trial battle ensuing' is the wordplay.
'attorney general' becomes 'AG' (abbreviation).
'attending trial battle' becomes 'incourt' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ensuing' means one lot of letters go next to another (ensue can mean to follow).
'ag'+'incourt'='AGINCOURT'
Can you help me to learn more?
(Other definitions for agincourt that I've seen before include "Battleground" , "1415 battle in the Pas-de-Calais" , "Battle in Hundred Years' War" , "English victory in 1415" , "battle site" .)
