In France's darkest hours of World War II, a lone French voice emanated from BBC radio in an attempt to rally free French forces to resist the power of invading Germany. Recognizing his value as an ally, Winston Churchill acknowledged de Gaulle as the French leader despite the fact that a national government still existed in France. As he was forced to the sidelines of Allied Command decisions, de Gaulle led military campaigns defending France's colonies, building his reputation. Despite this, he was excluded from Normandy operations. He nonetheless accompanied US forces with great theatricality as they arrived in Paris, and was soon elected head of the French government. Years after his retirement, the French people turned to de Gaulle for guidance during the Algerian crisis, but his mythic position as the face of France would end during the social upheaval of the 1960s.
