Help With 199 Sq. Operations

Gentlemen. I recently acquired a log book to a Stirling bomb aimer with 199 Squadron. The log book contains many remarks “Spec Ops”, usually without target / destination names other than on some occasions, France.
Can anyone tell me if any of these were of a clandestine nature?

8.2.44 EE953 – France
11.2.44 EF192 – France
15.2.44 EF262 – France

7.3.44 EE910 – France
5.4.44 EE262 – France

8.8.44 LJ518
12.8.44 LJ

After this date he moved to 171 Squadron and all Special Ops are annotated with a destination in Germany.
Many thanks for your help.
