Move back, withdraw (7)
I believe the answer is:
retreat
I believe this is a double definition.
'move back' is the first definition.
(synonyms)
'withdraw' is the second definition.
(I know that retreat is a more specific form of the action the withdraw)
(Other definitions for retreat that I've seen before include "unhappy manoeuvre" , "care home" , "snug" , "concession" , "place for meditation" .)
