Died next to bones — that's war's story (5)
I believe the answer is:
iliad
'war's story' is the definition.
'died next to bones' is the wordplay.
'died' becomes 'd'.
'next to' is a charade indicator (letters next to each other).
'bones' becomes 'ilia' (plural of ilium).
'd' put after 'ilia' is 'ILIAD'.
'that's' is the link.
(Other definitions for iliad that I've seen before include "tale of woes" , "Homer's work" , "Work by Homer" , "Epic piece of writing" , "Homer Trojan war epic" .)
