French Forces of The Interior - Liberation

Liberation

After the invasion of Normandy in June 1944, at the request of the French Committee of National Liberation, SHAEF placed about 200,000 resistance fighters under command of General Marie Pierre Koenig, who attempted to unify resistance efforts against the Germans. General Eisenhower confirmed Koenig's command of the FFI on 23 June 1944.

The FFI were mostly composed of resistance fighters who used their own weapons, although many FFI units included former French soldiers. They used civilian clothing and wore an armband with the letters "F.F.I."

According to General Patton, the rapid advance of his army through France would have been impossible without the fighting aid of the FFI. General Patch estimated that from the time of the Mediterranean landings to the arrival of U.S. troops at Dijon, the help given to the operations by the FFI was equivalent to four full divisions.

FFI units seized bridges, began the liberation of villages and towns as Allied units neared, and collected intelligence on German units in the areas entered by the Allied forces, easing the Allied advance through France in August 1944. According to a volume of the U.S. official history of the war,

In Brittany, southern France, and the area of the Loire and Paris, French Resistance forces greatly aided the pursuit to the Seine in August. Specifically, they supported the Third Army in Brittany and the Seventh U.S. and First French Armies in the southern beachhead and the Rhône valley. In the advance to the Seine, the French Forces of the Interior helped protect the southern flank of the Third Army by interfering with enemy railroad and highway movements and enemy telecommunications, by developing open resistance on as wide a scale as possible, by providing tactical intelligence, by preserving installations of value to the Allied forces, and by mopping up bypassed enemy positions.
