The craft bearing the U.S. 4th Infantry Division assaulting Utah were pushed by the current to a spot about south of their intended landing zone. The troops met light resistance, suffering fewer than 200 casualties. Their efforts to push inland fell far short of their targets for the first day, but they were able to advance about , making contact with the 101st Airborne Division. The airborne landings west of Utah were not very successful, as only ten per cent of the paratroopers landed in their drop zones. Gathering the men together into fighting units was made difficult by a shortage of radios and by the terrain, with its hedgerows, stone walls and marshes. The 82nd Airborne Division captured its primary objective at Sainte-Mère-Église and worked to protect the western flank. Its failure to capture the river crossings at the River Merderet resulted in a delay in sealing off the Cotentin Peninsula. The 101st Airborne Division helped protect the southern flank and captured the lock on the River Douve at La Barquette, but did not capture the assigned nearby bridges on the first day.
