Faction involved in exploit did a runner (8)

I believe the answer is:
decamped
'did a runner' is the definition.
The answer and definition can be both to do with motion as well as being past participle verbs.
Maybe there's an association between them I don't understand?
'faction involved in exploit' is the wordplay.
'faction' becomes 'camp' (both can mean a side in an argument).
'involved in' is an insertion indicator.
'exploit' becomes 'deed' (both can mean a feat or escapade).
'camp' put into 'deed' is 'DECAMPED'.
Can you help me to learn more?
(Another definition for decamped that I've seen is " Went away suddenly or secretly".)
