Answer:
The turning point that was the most significant to the Allied victory in Europe was Operation Overlord, the landing in Normandy.
Step-by-step explanation:
During World War II, Operation Overlord was the code name for the invasion by Western Allies in German-occupied Western Europe. Operation Overlord began on June 6, 1944 with the largest amphibious invasion in history. It was the beginning of the liberation of Western Europe. In Eastern Europe, the Germans were already losing the Soviet Union, and two days earlier, Rome had been conquered by the Allies.
The operation started with airborne landings and a massive amphibious assault in the early morning of June 6. After the landing, efforts were first made to preserve and expand the Norman bridgehead. Various operations were undertaken for this and during Operation Cobra the Allies finally broke through the German lines. When the Germans got trapped at Falaise, the battle was decided in the Allied favor. The road to Paris was open and the French capital was captured. The liberation of Paris is generally considered to be the end of Operation Overlord.
Overlord's first day was referred to as D-day, a term often associated with the entire operation.
