Raid and plunder (6)
I believe the answer is:
maraud
'raid and plunder' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for maraud that I've seen before include "Sack" , "Go searching for people to attack" , "Go in search of plunder" , "Go raiding for plunder" , "Wander in search of plunder" .)
