I believe the answer is:

nelson

I'm a little stuck... Click here to teach me more about this clue!

'victory was doubly his' is the definition.
The definition suggests a singular noun which matches the answer.

This is the entire clue.

Can you help me to learn more?

(Other definitions for nelson that I've seen before include "18th century admiral" , "Trafalgar victor" , "Tar" , "Admiral; wrestling hold" , "'England expects' admiral" .)

I've seen this clue in The Guardian and The Globe and Mail.
