Nelson on track to lose Trafalgar, initially upset (5)
I believe the answer is:
pique
'nelson on track' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for pique that I've seen before include "nark" , "Animosity" , "Show of annoyance" , "Wound (pride); resentment" , "Nettle" .)
