Under the narrow doctrinal definition used here, an amphibious operation begins with a force based at sea and maneuvering against the shore. Many of the larger Normandy landing craft instead sailed directly from Britain across the Channel. On that basis, D-Day is classified as an immense shore-to-shore movement, closer to an expanded river crossing than to an assault launched from a sea base. The deliberately counterintuitive distinction concerns basing and maneuver; it says nothing about the landings' scale, danger, or complexity.

Was D-Day technically an amphibious operation?
Under a narrow doctrinal definition, the Normandy landings were an enormous shore-to-shore movement rather than an assault launched from a sea base.
