Operation Dingson

Operation Dingson (5–18 June 1944) was an operation in the Second World War, conducted by about 178 Free French paratroops of the 4th Special Air Service (SAS), commanded by Colonel Pierre-Louis Bourgoin, who jumped into German occupied France near Vannes, Morbihan, Southern Brittany, in Plumelec, on the night of 5 June 1944 (11 h 30) with Captain Pierre Marienne and 17 men, then into Saint-Marcel (8–18 June).

At this time, there were approximately 100,000 German troops, and artillery, preparing to move to the Normandy landing areas.

Immediately upon landing in Brittany, on the night of 5 June 1944 (11 h 30), 18 Free French SAS who jumped in near Plumelec, went into action fighting against German troops (Vlassov's army).

One hour later (0 h 40), the first victim of the liberation of his country, Corporal Emile Bouétard (born in Brittany, 1915) was killed near Plumelec.

The Free French SAS established a base (Saint-Marcel) and began to arm and equip members of local resistance fighters, operating with up to 3,000 Maquis fighters. However, their base was heavily attacked by a German paratroop division on 18 June and were forced to disperse.

Captain Pierre Marienne with 17 of his companions (6 paratroopers, 8 resistance fighters and 3 farmers) died a few weeks later in Kerihuel, Plumelec, (12 July at dawn).

The Dingson team was joined by the men who had just completed Operation Cooney. Dingson was conducted alongside Operation Samwest and Operation Lost. Parts of Overlord.
