So Nelson had the Victory, I had heard (3-4)
I believe the answer is:
one-eyed
'so nelson had' is the definition.
I can't judge whether this definition defines the answer.
'victory i had heard' is the wordplay.
'victory' becomes 'one' (I can't explain this - if you can you should believe this answer much more).
'i had' becomes 'i'd' (I'd).
'heard' indicates a 'sounds like' (homophone) clue.
'id' is a homophone of 'eyed'.
'one'+'eyed'='ONE-EYED'
'the' is the link.
(Other definitions for one-eyed that I've seen before include "''In the country of the blind, the . . .-. . . . man is King''" , "Like the Jack of spades or hearts" , "Like Cyclops" , "Monocular" .)
