Operation THEOREM/VALIANT

From the point of view of John Austin’s crew this was a smooth, uneventful and successful operation to drop a pair of agents. The journey out is via Dives-sur-Mer, Tours, Chateauroux and Montluçon. The agents are dropped at 01.54, three minutes after reaching the target, near the village of St. Désiré, north of Montluçon. Austin probably pinpointed on Montluçon before backtracking to the target. On the way back pigeons are dropped near Argentan, and Austin lands back at Newmarket at 05.55.

For one of the agents it is a different story: although Jacques de Vaillant Guelis (VALIANT) a senior ‘F’ Section officer, lands without difficulty and is recovered by Lysander on the night of 4 September (Operation ‘Night Embarkation’ as the pilot, S/Ldr John Nesbitt-Dufort, entitles his report), but Gilbert Turck (THEOREM) is knocked out in an awkward landing. He wakes to find himself in a Vichy police station in Montluçon. During the Phoney War he had been a liaison officer between the sabotage-oriented Section ‘D’ of SIS and the similarly-tasked 5ème Bureau; his old boss, now working for Vichy’s intelligence service, has him released. Turck regains contact with de Guelis, and starts his mission.

(Operation ADJUDICATE)

Knowles and his crew take off at 22.07, quite late for a sortie heading for the south of France at that time of year. The rear gunner is a Squadron Leader Stephens, a gunnery instructor from 3 Group’s HQ Flight.

They fly a near-regular route: Abingdon, Tangmere, near-Cabourg, then Tours to Limoges, which they reach at 1.34. They find the target without difficulty, but they are greeted by the signal code ‘MD’, meaning that to land the agent would be dangerous. They circle for about ten minutes, but no further signals are seen. Headlights are seen on the ground and the Whitley leaves the area. Knowles offers to drop the agent elsewhere in Unoccupied France, an offer declined.

They fly back via Tours, landing back at Newmarket at 05.52.

The reason the operation name and agent are in brackets is that the evidence to identify them is circumstantial. In his operations report Knowles incorrectly ascribes it to the FELIX network, which did not operate in that area of south-west France. (Three nights earlier Knowles and his crew had flown an attempt to drop a W/T set to FELIX near Fontainebleau, but had turned back early with engine-trouble.) Characteristically Knowles does not include the date of the sortie in his report, but the take-off and landing times match those recorded in the Stradishall log for an otherwise unascribed sortie by Whitley (letter ‘D’) on 6th August. The target description in Knowles’s report, and the fact that the cargo is an agent not a W/T set, points towards another attempt to insert Count Dzieřgowski into the Unoccupied Zone near Limoges.

Operational cross-country

This Lysander sortie appears in Nesbitt-Dufort’s logbook, with a take-off from Tangmere at 23:00 hrs, and landing 5 hours 40 minutes later.

For all his other operational sorties, Nesbitt-Dufort records them as either ‘Ops as ordered successful or ‘Ops as ordered unsuccessful, and notes the number of passengers. This one is recorded merely as ‘Ops as ordered’, and as a solo effort, with no passengers.

This looks like a similar operation to the one described by Hugh Verity as an ‘operational cross-country’, in which Verity, soon after he joined 161 Squadron, was ordered to fly to a point in France, note what he saw, and to fly back and report. In Verity’s case the target was a brightly-lit prison camp in the countryside south of Saumur. Such sorties provided a realistic test of the pilot’s solo navigational abilities without exposing a valuable agent to any risk. Nesbitt-Dufort has flown several Whitley operations, and has proved himself as a competent map-reader, but those sorties are rather different from flying alone to a pinpoint on the map, several hundred miles into Occupied France. Next time he will do it with an agent aboard.
