The pathfinders of the 101st Airborne Division led the way on D-Day in the night drop before the invasion. They left from RAF North Witham, having trained there with the 82nd Airborne Division. These night drops caused a lot of trouble for the gliders. Many crashed and equipment and personnel were lost.

The 101st Airborne Division's objectives were to secure the four causeway exits behind Utah Beach between Saint-Martin-de-Varreville and Pouppeville to ensure the exit route for the 4th Infantry Division from the beach later that morning. The other objectives included destroying a German coastal artillery battery at Saint-Martin-de-Varreville, capturing buildings nearby at Mésières believed used as barracks and a command post for the artillery battery, capturing the Douve River lock at La Barquette (opposite Carentan), capturing two footbridges spanning the Douve at La Porte opposite Brévands, destroying the highway bridges over the Douve at Saint-Côme-du-Mont, and securing the Douve River valley. Their secondary mission was to protect the southern flank of VII Corps. They destroyed two bridges along the Carentan highway and a railroad bridge just west of it. They gained control of La Barquette locks, and established a bridgehead over Douve River which was located north-east of Carentan.
