As the 8th Marines advanced, their front expanded, and at 11:30 the commander, Colonel Wallace, ordered his 2d Battalion up on the 1st Battalion's right to attack eastward. This zone included the built-up area around Ushi Point Airfield as well as the strip itself. Since most of the Japanese troops originally assigned to this area had expended themselves against the 1st Battalion, 24th Marines, on the night of Jig-Day, they could oppose this attack only with occasional, ineffective small-arms fire. The advance swept rapidly through the area. The 1st Battalion, too, gained momentum after destroying the beach strong-point and pushed northeastward along the coast. By dark the 8th Marines, having pushed about 200 yards past Objective O-2, stopped and carefully tied in lines for the night.
