Foray: angry about it arising (6)
I believe the answer is:
sortie
'foray' is the definition.
(both can mean an attack)
'angry about it arising' is the wordplay.
'angry' becomes 'sore' (similar in meaning).
'about' means one lot of letters goes inside another.
'arising' is a reversal indicator.
'it' back-to-front is 'ti'.
'sore' placed around 'ti' is 'SORTIE'.
(Other definitions for sortie that I've seen before include "Military manoeuvre" , "Military raid" , "Short trip; attack" , "Sally" , "Raid - short trip" .)
