Francis Basin LdH CdeG MBE (1903–1975), code named Olive, was an agent of the United Kingdom's clandestine Special Operations Executive in France during the Second World War.

The purpose of SOE was to conduct espionage, sabotage, and reconnaissance in countries occupied by the Axis powers, especially Nazi Germany.

In August 1940, he enlisted in the British army on the advice of Colonel Massip to whom he was secretary and who was close to General de Gaulle.

On 28 August 1941, he sailed from England to Gibraltar in HMS Fidelity in Operation AUTOGYRO and on the night of 19/20 September 1941 landed by submarine at Le Barcarès near Perpignan with Robert Leroy "Louis", Raymond Roche "François", and Georges Duboudin "Alain".

Baron Henri Ravel of Malval "Antoine", whom he knew at the beginning of the war and whom he met by chance in Cannes, put his house at his disposal.

[4][6] Impressed by the possibilities of contact with London that Basin could assure, André Girard agreed to send one of his officers to England, and chose Henri Frager, his second in command.

Taking advantage of the departure of Max Hymans "Frédéric" for London, Basin sent a report on his relations with the MAP network.

On the night of 27/ 28 August 1942 Peter Churchill returned to the south of France to take over the URCHIN network in the Midi under the name of SPINDLE.

[5] On 4 September 1942 there was a failed attempt by the MAP network to rescue Basin in a train taking him to Montluc prison in Lyon.
