Ravage, plunder (5)
I believe the answer is:
harry
I believe this is a double definition.
'ravage' is the first definition.
(I know that ravage can be written as harry)
'plunder' is the second definition.
(I've seen this in another clue)
(Other definitions for harry that I've seen before include "Hector" , "Persistently harass" , "Male" , "Make repeated attacks on, badger" , "English prince - trouble" .)
