Operations along Red 2 and Red 3 were considerably more difficult. During the night the defenders had set up several new machine gun posts between the closest approach of the forces from the two beaches, and fire from those machine gun nests cut off the American forces from each other for some time. By noon the U.S. forces had brought up their own heavy machine guns, and the Japanese posts were put out of action. By the early afternoon they had crossed the airstrip and had occupied abandoned defensive works on the south side.
