Flee, abscond (6)
I believe the answer is:
decamp
I believe this clue is a double definition.
'flee' is the first definition.
(decamping is a kind of fleeing)
'abscond' is the second definition.

(Other definitions for decamp that I've seen before include "Fold up tent and depart" , "Leave suddenly" , "Run away (from responsibility)" , "Make off - from tent?" , "Make sudden breakaway" .)
