Sally, raid (6)
I believe the answer is:
sortie
I believe this is a double definition.
'sally' is the first definition.
(I know that sally can be written as sortie)
'raid' is the second definition.
(I have seen 'Military raid' mean 'sortie' so perhaps 'raid' could also mean 'sortie')
(Other definitions for sortie that I've seen before include "Warplane's flight" , "Sudden attack by besieged troops" , "Military aircraft flight" , "Sally" , "Military foray" .)
