What was the goal of the D-Day invasion for the allies?

The goal of the D-Day invasion, officially known as Operation Overlord, was to establish a strong Allied foothold in Nazi-occupied Europe by landing troops on the beaches of Normandy, France, on June 6, 1944. This operation aimed to break through German defenses, liberate Western Europe from Nazi occupation, and ultimately facilitate the defeat of Germany in World War II. By opening a new front, the Allies sought to divert German resources and attention, aiding the Soviet Union in the east. Successful execution of D-Day was pivotal in shifting the momentum of the war in favor of the Allies.
