Floral tribute to recollect the war (6)
I believe the answer is:
wreath
'floral tribute' is the definition.
(I've seen this before)
'recollect the war' is the wordplay.
'recollect' is an anagram indicator.
'the'+'war'='thewar'
'thewar' with letters rearranged gives 'WREATH'.
'to' acts as a link.
(Other definitions for wreath that I've seen before include "Circular band of flowers and leaves, often seen on graves" , "Circlet (of laurel)" , "Circle of flowers in honour of dead" , "Flower arrangement" , "Circular band, of flowers say" .)
