Two companies from Kawaguchi's 2nd Battalion charged up the southern edge of the ridge and pushed Edson's troops back to Hill 123 on the center part of the ridge. Throughout the night Marines at this position, who were supported by artillery, defeated wave after wave of frontal Japanese attacks, some of which resulted in hand-to-hand fighting. Japanese units that infiltrated past the ridge to the edge of the airfield were also repulsed. Attacks by the Kuma battalion and Oka's unit at other locations on the Lunga perimeter were also defeated. On 14 September Kawaguchi led the survivors of his shattered brigade on a five-day march west to the Matanikau Valley to join with Oka's unit. In total Kawaguchi's forces lost about 850 killed and the Marines 104.
