Notoriously, the American troops who landed at Omaha Beach suffered the worst on D-Day. The bombardments before the Landings proved ineffective in wiping out the many German positions dotted along the slopes above the beaches beyond Colleville-sur-Mer, Saint-Laurent-sur-Mer and Vierville-sur-Mer. On top of that, the Allied amphibious tanks were launched too far out from the shore and failed. The infantry coming ashore were decimated by German fire across the long beaches. Despite heavy losses, small groups of Americans made it up the slopes and took German positions from behind, so some gains were made, if at heavy human cost. At the end of the day, the forces that landed here suffered 3,000 casualties, of whom c.1,000 died.
