Five Turkish and British commanders in Rover (8)
I believe the answer is:
vagabond
'rover' is the definition.
(vagabond is a kind of rover)
'five turkish and british commanders' is the wordplay.
I cannot quite understand how this works, but
'five' could be 'v' (Roman numeral) and 'v' is found within the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is present in the answer.
'british' could be 'b' (abbreviation e.g. in 'BBC') and 'b' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for vagabond that I've seen before include "Down-and-out" , "One wandering" , "An idle or dishonest wanderer" , "An idle or dishonest vagrant" , "Roving" .)
