Pierre Georges (21 January 1919 – 27 December 1944), better known as Colonel Fabien, was one of the two members of the French Communist Party who perpetrated the first assassinations of German personnel during the Nazi Occupation of France in the Second World War.

In 1940, Georges joined the French Resistance in the Francs-Tireurs et Partisans, at the time still largely operating by sabotaging German equipment in France.

At a session on 15–17 August it was agreed that members of the JC should receive weapons training and increase sabotage and attacks on occupation troops.

[6] Colonel Fabien organized a Free French (FFI: Forces Françaises de l'Intérieur) column that left Paris soon after the uprising in that city early in September 1944.

The Colonne Fabien was to form the nucleus of a Free French force in Lorraine, which would be joined by volunteers from Paris and the eastern regions of France as soon as possible.
