Edie's gang managed to separate (9)
I believe the answer is:
disengage
'separate' is the definition.
(I've seen this in another clue)
'edie's gang managed' is the wordplay.
'managed' indicates an anagram.
'edies'+'gang'='ediesgang'
'ediesgang' with letters rearranged gives 'DISENGAGE'.
'to' is the link.
(Other definitions for disengage that I've seen before include "Remove (troops) from a conflict" , "free" , "Withdraw" , "Separate, release, detach" .)
