Pagan with 500 depressed troops going up gully? (9)
I believe the answer is:
infielder
'pagan' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for infielder that I've seen before include "Baseballer" , "gully, perhaps" .)
