Glad to have depended on taking victory (8)
I believe the answer is:
relieved
'glad' is the definition.
(I've seen this before)
'depended on taking victory' is the wordplay.
'depended on' becomes 'relied' (I've seen this in another clue).
'taking' means one lot of letters goes inside another.
'victory' becomes 'VE' (VE is short for Victory in Europe).
'relied' enclosing 've' is 'RELIEVED'.
'to have' is the link.
(Other definitions for relieved that I've seen before include "Sort of feeling one gets" , "'Alleviated, lightened (8)'" , "Thankful" , "Not so anxious - replacement has arrived" , "Freed from distress" .)
