Charles de Gaulle had to be forced to attend, and he met a chilly reception from Roosevelt and Churchill.
No French representatives were allowed to attend the military planning sessions.

The conference called for the official recognition of a joint leadership of the Free French forces by de Gaulle and Henri Giraud.
There was notable tension between the two men, who limited their interactions to formalities like pledging their mutual support.
Roosevelt encouraged them to shake hands for the photographers eager for a photo opportunity, but the ritual handshake was with reluctance and done so quickly that they reportedly had to pose for a second shot.
Roosevelt would later describe this meeting between the French leaders as a "shotgun wedding".

Elliott Roosevelt’s book, As He Saw It (1946) describes how Franklin Roosevelt wanted the French provisional government to be set up with Giraud and de Gaulle, who would be “equally responsible for its composition and welfare.” (
89) That is because Franklin Roosevelt saw de Gaulle as Churchill’s puppet and thought that Giraud would be more compliant with US interests.
Complications arose because most people in the French Resistance considered de Gaulle the undisputed leader of the Resistance and so Giraud was progressively dispossessed of his political and military roles.
Roosevelt eventually recognized de Gaulle as the head of the Free French in mid-1944.
