 two companies waited at the edge of the jungle for reinforcements to arrive before attacking into the open area around the airfield . When no reinforcements joined them , both companies went back to their original positions south of the ridge after daybreak . Most of the rest of Watanabe 's battalion did not participate in the battle because they lost contact with their commander during the night .   As the sun rose on 14 September , pockets of Japanese soldiers remained scattered along both sides of the ridge . But with Tamura 's battalion shattered after losing ¾ of its officers and men , and with heavy casualties to his other attacking units as well , Kawaguchi 's assault on the ridge had effectively ended . About 100 Japanese soldiers still remained in the open on the south slope of Hill 80 , perhaps preparing for one more charge on Hill 123 . At first light , three U.S. Army aircraft from the 67th Fighter Squadron at Henderson Field , acting on a request personally delivered by Bailey , strafed the Japanese near Hill 80 and killed most of them , with the few survivors retreating back into the jungle .   = = = Kuma and Oka attacks = = =   As the battle on the ridge took place , Kawaguchi 's Kuma and Oka units also attacked the Marine defenses on the east and west sides of the Lunga perimeter . The Kuma battalion — led by Major Takeshi Mizuno — attacked the southeastern sector of the Lunga perimeter , defended by Marines of the 3rd Battalion , 1st Marine Regiment ( 3 / 1 ) . Mizuno 's attack started around midnight , with one company attacking through Marine artillery fire and engaging in hand @-@ to @-@ hand combat with the Marine defenders before being thrown back . Mizuno was killed in the attack . After daybreak , the Marines , believing that the rest of Mizuno 's battalion was still in the area , sent forward six light tanks without infantry support to sweep the area in front of the Marine lines ; four Japanese 37 mm ( 1 @.@ 46 in ) anti @-@ tank guns destroyed or disabled three of them . After abandoning their burning tanks , several of the disabled tanks ' crewmembers were bayoneted and killed by the Japanese . One tank tumbled down an embankment into the Tenaru River , drowning its crew .   At 23 : 00 on 14 September , the remnants of the Kuma battalion conducted another attack on the same portion of the Marine lines , but were repulsed . A final " weak " attack by the Kuma unit on the evening of 15 September was also defeated .   Oka 's unit of about 650 men attacked the Marines at several locations on the west side of the Lunga perimeter . At about 04 : 00 on 14 September , two Japanese companies attacked positions held by the 3rd Battalion , 5th Marine Regiment ( 3 / 5 ) near the coast and were thrown back with heavy losses . Another Japanese company captured a small ridge somewhat inland but was then pinned down by Marine artillery fire throughout the day and took heavy losses before withdrawing on the evening of 14 September . The rest of Oka 's unit failed to find the Marine lines and did not participate in the attack .   = = Aftermath = =   At 13 : 05 on 14 September , Kawaguchi led the survivors of his shattered brigade away from the ridge and deeper into the jungle , where they rested and tended to their wounded all the next day . Kawaguchi 's units were then ordered to withdraw west to the Matanikau River valley to join with Oka 's unit , a 6 mi ( 9 @.@ 7 km ) march over difficult terrain . Kawaguchi 's troops began the march on the morning of 16 September . Almost every soldier able to walk had to help carry the wounded . As the march progressed , the exhausted and hungry soldiers , who had eaten their last rations on the morning before their withdrawal , began to discard their heavy equipment and then their rifles . By the time most of them reached Oka 's positions at Kokumbona five days later , only half still carried their weapons . The Kuma battalion 's survivors , attempting to follow Kawaguchi 's Center Body forces , became lost , wandered for three weeks in the jungle , and almost starved to death before finally reaching Kawaguchi 's camp .   In total , Kawaguchi 's forces lost about 830 killed in the attack , including 350 in Tamura 's battalion , 200 in Kokusho 's battalion , 120 in Oka 's force , 100 in the Kuma battalion , and 60 in Watanabe 's battalion . An unknown number of wounded also died during the withdrawal march to the Matanikau . On and around the ridge , the Marines counted 500 Japanese dead , including 200 on the slopes of Hill 123 . The Marines suffered 80 killed between 12 and 14 September .   On 17 September , Vandegrift sent two companies from the 1st Battalion , 1st Marine Regiment ( 1
