Keeping a pretty busy axe shaped the battle record (6,8)
I believe the answer is:
bayeux tapestry
'battle record' is the definition.
The definition suggests a singular noun which matches the answer.
'keeping a pretty busy axe shaped' is the wordplay.
'keeping' indicates putting letters inside (some letters kept inside).
'shaped' indicates an anagram.
'pretty'+'busy'+'axe'='prettybusyaxe'
'prettybusyaxe' is an anagram of 'byeuxtapestry'.
'a' put within 'byeuxtapestry' is 'BAYEUX TAPESTRY'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for bayeux tapestry that I've seen before include "Historic needlework item" , "long old length of carpet" .)
