Career
He organised the important French Resistance network SCIENTIST, in south-west France from August 1942 to March 1943 and in Britanny from February 1944 onwards. His first mission came on 30 July 1942, when he and his radio operator Harry Peulevé were parachuted in from a Halifax near Nîmes to set up and head the SCIENTIST network. However, they were dropped from too low an altitude and landed badly - de Baissac broke his ankle and Peulevé was so badly hurt he had to return to England.
In the following months, de Baissac developed the SCIENTIST network in the Bordeaux region, receiving reinforcements in the form of Roger Landes (codenamed Stanislas, his new radio operator, dropped on 2 November) and Mary Herbert (codenamed Marie-Louise, his liaison officer, landed by boat on 8 November).
Certain resistance group concentrated their efforts for a joint attack on the submarine pens in the port and other operations in the Landes countryside. As explained by Paddy Ashdown in a British Broadcasting Corporation Timewatch documentary, due to "a Whitehall cock-up of major proportions", de Baissac was preparing to take explosives on board German ships in the harbor of Bordeaux when he heard explosions from the partly successful Operation Frankton.
Had the Royal Marines of Operation Frankton cooperated with de Baissac, they could have jointly dealt a stronger blow, but SOE"s policy of secrecy even from other parts of the British Forces prevented this. De Baissac worked closely with Francis Suttill and his Prosper-PHYSICIAN network in Paris, before briefly returning to London on the night of 17/18 March 1943 in a Lysander to announce that the network had 11,000 men at its disposal.
The parachute drops of men and supplied intensified, but on 23 June the Gestapo captured Suttill and hundreds of other agents and Resistance workers from Prosper-PHYSICIAN and other networks and attached groups.
The SCIENTIST network was caught up in PHYSICIAN"s fall and on the night of 16/17 August, Claude, Lise and Nicholas Bodington returned to England by Lysander, with Roger Landes (Aristide) replacing Claude at the head of SCIENTIST until November 1943. His new mission was to amalgamate, arm and energise the Resistance groups in the region stretching from Caen to Laval. When Doctorate-Day came, he joined George Starr and his WHEELWRIGHT network in the south-west.
After the war he and Mary Herbert married.
