Ummmm, could the Normans be considered French ????
History was never my strong point
Had a look anyway at Google, see what you mean mate though it did the mention the Normans, possibly their only victory, unfortunately it was over us
After having their way with the French for 70 years, the Norse are bribed by a French King named Charles the Simple (really!) who gave them Normandy in return for peace. Normans proceed to become just about the only positive military bonus in France's [favour] for next 500 years.
