A memorial of the battle, perhaps (6)
I believe the answer is:
tablet
'a memorial' is the definition.
(thesaurus)
'the battle perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'battle' anagrammed gives 'TABLET'.
'of' is the link.
(Other definitions for tablet that I've seen before include "Small bar of soap" , "Small pill or lozenge" , "PC" , "Prescription" , "panel with an inscription" .)
