"Leahy was by no means ready to accept the tall, vainglorious Frenchman as the natural leader of French interests. In common with most of his staff who had been with him in Vichy, he distrusted de Gaulle and his French Committee of National Liberation (FCNL). As early as the previous September, Leahy had expressed his views to friends in the State Department, and "Doc" Matthews had sent him a collection of letters and reports from Murphy and others naming chapter and verse of how de Gaulle and his followers had consistently undercut Giraud. Leahy had no particular brief for Giraud, but he was the one recognized by the British and Americans as French military leader in the Mediterranean. For the same reason de Gaulle had been kept in the dark before Torch- because his headquarters could not keep a secret- Giraud concealed from the FCNL his invasion of Corsica in September until just before the landings. De Gaulle's response was to use the FCNL, which he now dominated, to deprive "the French Commander-in-Chief of the authority and freedom of action which both he and our own military leaders have felt was essential. Such behavior, Leahy felt, was all of a piece with what was to be expected from Charles de Gaulle and his Free French. There was no living with de Gaulle, but because of decisions made by Churchill and FDR, Leahy had to try."
