... captured and tied up (8)
I believe the answer is:
occupied
I believe this clue is a double definition.
'captured' is the first definition.
(e.g. an occupied country or castle)
'tied up' is the second definition.
(I've seen this before)
'and' acts as a link.
(Other definitions for occupied that I've seen before include "In nineteen forty, Norway was" , "Employed" , "Inhabited or engaged" , "Busy or inhabited" , "as ladies often seem to be ..." .)
