Some 'hero' haltingly retiring somewhere in Asia (6)

I believe the answer is:

lahore

I'm a little stuck... Click here to teach me more about this clue!

'somewhere in asia' is the definition.
The definition suggests a singular noun which matches the answer.

'some hero haltingly retiring' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'retiring' says the letters should be written in reverse.
'erohal' is hidden within 'hero haltingly'.
'erohal' reversed gives 'LAHORE'.

Can you help me to learn more?

(Other definitions for lahore that I've seen before include "West Pakistan capital, 1955-70" , "Large domestic pigeon - city in Pakistan" , "City in NE Pakistan" , "Pak. Punjab city" , "Possible home for Pakistani" .)

I've seen this clue in The Everyman puzzle in The Observer.
