The landing beach closest to Normandy's largest port, Cherbourg, and regarded by the Germans as the most important Allied objective, Utah was isolated from the other D-Day beaches, meaning that that troops landing there would have to fight alone until a link-up could be achieved. Accordingly, the US First Army committed a powerful landing force, preceded by a night parachute and glider assault, part of the largest night drop ever mounted. Despite wide scattering, the airborne troops secured the critical communications centre of Ste Mere Eglise on D-Day, the first village in Normandy to be liberated. Supported by a devastating air and naval bombardment, although landing on the wrong beach in bad weather, 4th Infantry Division took only 197 casualties out of 23,000 troops that landed on D-Day, and by the early afternoon had begun to link up with the first of the paratroopers.
