In 1944 prior to D Day the allied planners realised it was vital to isolate the Normandy Battlefield from reinforcements. In particular it was essential to delay or stop the movement of 2 SS Pz Div (Das Reich) from the south of France. The initial plan called for the French Resistance to interdict the French Railway system to stop their movements. Doubts over the effectiveness of the resistance led to the deployment of 1st SAS to do the task. This programme covers both the deployment of a troop of B Sqn into the Poitiers, in what was known as OP BULBASKET, to delay the Das Reich and the movements and actions of the Das Reich as they move through the Dordogne and Vienne Regions culminating in the massacre at Oradour. Part 2 of this programme will cover the SAS actions in delaying the Das Reich.

This programme follows the deployment of the main body of the SAS, the Recces on targets, the raids carried out both by the SAS and the bombing attacks they called in. As the SAS created havoc to the railway system the Germans were hunting them down. Eventually by the use of torture and information by collaborators the Germans tracked them down to their camp near Verrieres. The majority of the SAS were killed or captured. Those captured were later murdered by the Germans.. Their actions tied up large numbers of Germans in guarding the railways and imposed a severe delay on the movements of the 2nd SS Pz Div to Normandy. A few brave men had an impact on the liberation of France out of all proportion to their numbers
