Females, having gained victory, surrounding me (5)
I believe the answer is:
women
'females' is the definition.
(woman is a kind of female)
'victory surrounding me' is the wordplay.
'victory' becomes 'won' (I've seen this before).
'surrounding' means one lot of letters goes inside another.
'won' going around 'me' is 'WOMEN'.
'having gained' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for women that I've seen before include "Ladies" , "half of our race" , "Adult human females" .)
