Clue:- Piece of armour provided? Didn't have to go to war, we hear.(9)
H-A-P-E-E
I can only come up with HEADPIECE which seems odd as piece is used in the clue, explanations or other ideas most welcome, Thanks
I don't believe the Indy would allow such an unsound clue - unsound in two ways (half the word in the clue; and an inaccurate homophone). But I've no better explanation.
