Litter of battle (5)
I believe the answer is:
sedan
I believe this clue is a double definition.
'litter' is the first definition.
(sedan is a kind of litter)
'battle' is the second definition.
(I've seen this before)
'of' is the link.
(Other definitions for sedan that I've seen before include "Chair used as transport" , "Saloon-car" , "Enclosed chair" , "Palanquin; car" , "Old carrying chair" .)
