The Presidential Unit Citation was awarded to the regiment for action during on 6 June 1944 on the beaches of Normandy.

A great invasion force stood off the Normandy coast of France as dawn broke on 6 June 1944: 9 battleships, 23 cruisers, 104 destroyers, and 71 large landing craft of various descriptions as well as troop transports, mine sweepers, and merchantmen—in all, nearly 5,000 ships of every type, the largest armada ever assembled. The naval bombardment that began at 0550 that morning detonated large minefields along the shoreline and destroyed a number of the enemy’s defensive positions. To one correspondent, reporting from the deck of the cruiser HMS Hillary, it sounded like “the rhythmic beating of a gigantic drum” all along the coast. In the hours following the bombardment, more than 100,000 fighting men swept ashore to begin one of the epic assaults of history, a “mighty endeavor,” as President Franklin D. Roosevelt described it to the American people, “to preserve. . . our civilization and to set free a suffering humanity.”

25 July - 14 September 1944

As July 1944 entered its final week, Allied forces in Normandy faced, at least on the surface, a most discouraging situation. In the east, near Caen, the British and Canadians were making little progress against fierce German resistance. In the west, American troops were bogged down in the Norman hedgerows. These massive, square walls of earth, five feet high and topped by hedges, had been used by local farmers over the centuries to divide their fields and protect their crops and cattle from strong ocean winds. The Germans had turned these embankments into fortresses, canalizing the American advance into narrow channels, which were easily covered by antitank weapons and machine guns. The stubborn defenders were also aided by some of the worst weather seen in Normandy since the turn of the century, as incessant downpours turned country lanes into rivers of mud. By 25 July, the size of the Allied beachhead had not even come close to the dimensions that pre–D-day planners had anticipated, and the slow progress revived fears in the Allied camp of a return to the static warfare of World War I. Few would have believed that, in the space of a month and a half, Allied armies would stand triumphant at the German border.
