Hung second painting depicting battle, though they resisted strongly (3,2,1,5)
I believe the answer is:
put up a fight
'they resisted strongly' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'hung second painting depicting battle' is the wordplay.
I cannot really see how this works, but
'hung' could be 'up' (hung up) and 'up' is found within the answer.
'battle' could be 'fight' (synonyms) and 'fight' is present in the answer.
'second painting' could be 'a' (2nd letter of 'painting') and 'a' is located in the answer.
The remaining letters 'put' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'though' is the link.
Can you help me to learn more?
