America's first ground offensive of WWII began with soldiers waving giant American flags at French troops they hoped wouldn't fire — and it mostly worked.
When 107,000 Allied troops landed on the beaches of French Morocco and Algeria on November 8, 1942, many carried giant American flags. The hope was that Vichy French defenders would hesitate to fire on Americans specifically, since the US had stayed neutral and French officers harbored particular resentment toward Britain.
Operation Torch was America's first major ground offensive of the war in Europe — and politically as complicated as it was military. The 125,000 Vichy French defenders were simultaneously allied with Germany, nominally independent, and being asked by an invading force to switch sides.
Resistance was wildly inconsistent. Some French units fought fiercely around Casablanca, sinking Allied ships and inflicting significant casualties. Others laid down arms immediately or simply stepped aside. Individual French officers made individual choices, and the outcome at each location depended entirely on who was in command.
The political solution came through Admiral François Darlan, a senior Vichy official who happened to be in Algiers visiting his ill son when the landings occurred. After initial resistance, Darlan agreed to order all French forces to cease fighting in exchange for being named High Commissioner of French North Africa.
Admiral Darlan was assassinated on Christmas Eve 1942 by a French monarchist acting alone. The killing was never fully explained, feeding conspiracy theories that persist today — Darlan was deeply unpopular with almost everyone involved, including the Americans who had made the deal with him.
Operation Torch was the strategic compromise that held the Allied coalition together. Churchill had pushed hard for North Africa; the Americans wanted to invade France directly. North Africa was the middle ground — and it gave American forces their first real combat experience before the much harder fights in Sicily, Italy, and Normandy.
