Why+the+Invasion+occurred.

** Why did the invasion even take place? ** Officially, "Operation Overlord" was the designated code-name for the Allied offensive that would run from June to August 1944; the naval and beach assault operations on the day of June 6 were code-named "Operation Neptune," that coincided with various other operations, such as airborne drops, given their own code names. The plan of the airborne drops was to gain a foothold on mainland Europe and liberate it from Nazi occupation.
