Omaha beach was one of the landing beaches assigned to the Americans for landing in France on D-Day. This is where they suffered the most casualties while fighting against Germans troops in hopes of liberating Europe (30% of all casualties of the D-Day). Hence the name « Bloody Omaha » or « the Beach of blood ».
The name Omaha was used as a code name during Operation Overlord, chosen because it was the place of birth of one of the officers engaged in the operation (the city of Omaha in Nebraska). The same with the other American beach, Utah beach, state of birth of another American officer.
Located a few meters away, the American cemetery of Colleville-sur Mer overlooks the beach.
