I want to know the answer to the following question:
Who was the leader of French forces in this period?
All the background I'm provided with is that "His first struggles, however, were with Allied leaders and officers on matters vital to the success of the Normandy invasion; he argued with Roosevelt over an essential agreement with De Gaulle to use French resistance forces in covert and sabotage operations against the Germans in advance of Overlord.". Is that enough to answer the question?
