To complete the capture of Carentan, Gen. Courtney Hodges of First Army created a task force under Gen. Anthony McAuliffe to coordinate the final assault. The mission to take Hill 30 was reassigned to the 506th PIR, the attack along the Bassin à Flot was renewed, and the 501st PIR was relieved of its defensive positions to circle behind the 327th GIR and approach Hill 30 from the east. The movements were covered by an all-night artillery bombardment of Carentan using naval gunfire, Corps artillery, 4.2-inch mortars, and tank destroyers that had joined the 327th GIR along the eastern canal.

Both units encountered machine gun fire from the rear guard, but the 2nd/506th was also sporadically shelled by artillery to the south of Carentan. Despite this, both units swiftly cleaned out the rear guard in a short fight near the railroad station and met at 07:30 in the center of town. The 1st/506th PIR engaged in more serious combat south of town when it had to rescue Col. Sink's command post, surrounded because it had pushed too far towards the German lines in the dark.
In the afternoon both the 506th and 501st advanced southwest but after a mile were stopped by heavy contacts with new German units including a few tanks. The 17th SS Panzergrenadier Division had intended to counterattack to retake Carentan, but its assault guns were held up in the assembly areas by Allied air a...
