Run away from rebel operations (5)
I believe the answer is:
elope
'run away' is the definition.
(I've seen this before)
'from rebel operations' is the wordplay.
'from' says the answer is hidden in the clue.
'ELOPE' is hidden within 'rebel operations'.
(Other definitions for elope that I've seen before include "Run away with lover" , "Run away to Gretna Green?" , "escape" , "Do a runner" , "(Lovers) run away" .)
