Omaha Beach and Utah Beach were two of five sectors that made up the Allied invasion of German occupied France. They are located on the coast of Normandy, facing the English Channel, and are each 5 miles long.
Taking Omaha was the responsibility of the United States soldiers, with sea transport and naval artillery support provided by the U.S. Navy and elements of the British Royal Navy.
These two maps of Omaha beach alerted the 1st and 29th U.S. Divisions, the 5th Ranger Battalion, and 5th Engineer Special Brigade to the expected obstacles that they would encounter when they landed on June 6, 1944.
In addition to Omaha Beach, the U.S. soldiers assaulted Utah Beach. These two maps of Utah Beach alerted the VII U.S. Corps and the U.S. 82nd and 101st Airborne Divisions to the obstacles that they would encounter when they landed.
