Did 138 Sqn or 161 Sqn RAF use RAF Christchurch in 1943-44?

An old Fleet Air Arm contact of mine who was based at RAF Christchurch, Hampshire (now Dorset!) from November 1943 till VE-Day remembers seeing black painted Westland Lysanders on the airfield on a few occasions. Could it be that this airfield was a forward base for SOE ops over the Cherbourg Peninsula, in the same way that Tangmere was also a forward base. Some people have suggested these arrivals & departures were to do with the SOE training base at Beaulieu, at Lord Montague's Mansion but they could just have easily used RAF Beaulieu! And from what I have read of SOE & 138 & 161 Sqns, the trained SOE agents were usually taken to RAF Tempsford in great secrecy, rather than be picked up on the way by an aircraft coming down south to get them!

The only other explanation for this sighting is that there was some other RAF Sqn that operated black painted Lysanders for some other purpose!

Has anyone studied the ORB for either Sqn & seen reference to RAF Christchurch?
