At Bastogne, Belgium, the 327 held half of the perimeter (including the 401, which was acting as the Regiment's 3rd Battalion and later officially became a part of the 327). Numerous intense fights erupted along the 327 sector including two brutal fights at Marvie and more to the west in the 401 section. The Germans attacking were of the Volksgrenadiers and the elite tank-based Panzer Lehr. At Marvie the 327 was outnumbered by 15 to 1. Facing only two US companies, G Company, supported by several tanks from the 10th Armored Division and E Company in reserve, the German commander took his whole division further west. At Marvie, the Germans lost six tanks and several half tracks. One tank did break into Marvie, but was destroyed trying to make a run towards Bastogne. Several days later, during the night of 23 December, the enemy attacked in force with tanks. The road through Marvie was blocked when G Company mistook a US tank destroyer for a German tank and destroyed it on the village bridge. The Germans overran Hill 500 just to the west of Marvie and broke through the gap between F and G Company. The enemy then put rear pressure on the F Company Command Post. A platoon sized paratrooper element came to support F Company. The German forces managed to place tanks behind US lines between Marvie and Bastogne. The glider men of Company G and Company F were pushed back from 500 to 1,000 yards during the intense fighting, but did not break. Unable to make quick progress, the Germans pressed the attack until morning, but withdrew when the German Command Center was destroyed by US artillery. Again, the 327 was badly outnumbered by the enemy.
