Famous solver's friend in battle? (8)
I believe the answer is:
hastings
'battle?' is the definition.
(Battle of Hastings, 1066 battle)
'famous solver's friend in' is the wordplay.
I cannot really see how this works, but
'in' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for hastings that I've seen before include "somewhere in Sussex" , "His angst (anag.)" , "Ten sixty six battle" , "place of battle" , "Not a good place for Harold" .)
