 / 1 ) to pursue the retreating Japanese . The Marines were ambushed by two Japanese companies acting as rear @-@ guards for the withdrawal , and one Marine platoon was pinned down as the rest of the Marines retreated . The Marine company commander requested permission to attempt to rescue his platoon but was denied by Vandegrift . By nightfall , the Japanese overran and nearly annihilated the platoon , killing 24 Marines with only a few wounded members of the platoon surviving . On 20 September , a patrol from Edson 's Raiders encountered stragglers from Kawaguchi 's retreating column and called in artillery fire that killed 19 of them .   As the Japanese regrouped west of the Matanikau , the U.S. forces concentrated on shoring up and strengthening their Lunga defenses . On 14 September , Vandegrift moved another battalion , the 3rd Battalion , 2nd Marine Regiment ( 3 / 2 ) , from Tulagi to Guadalcanal . On 18 September , an Allied naval convoy delivered 4 @,@ 157 men from the 3rd Provisional Marine Brigade ( the U.S. 7th Marine Regiment augmented by additional support units ) to Guadalcanal . These reinforcements allowed Vandegrift — beginning on 19 September — to establish an unbroken line of defense around the Lunga perimeter . Vandegrift 's forces ' next significant clashes with the Japanese occurred along the Matanikau River from 23 – 27 September and 6 – 9 October .   = = Significance = =   On 15 September , General Hyakutake at Rabaul learned of Kawaguchi 's defeat , the Imperial Japanese Army 's first defeat involving a unit of this size in the war . The general forwarded the news to the Imperial General Headquarters in Japan . In an emergency session , the top Japanese army and navy command staffs concluded that , " Guadalcanal might develop into the decisive battle of the war . " The results of the battle began to have a telling strategic impact on Japanese operations in other areas of the Pacific . Hyakutake realized that , in order to send sufficient troops and materiel to defeat the Allied forces on Guadalcanal , he could no longer support the major Japanese offensive on the Kokoda Track in New Guinea . Hyakutake — with the concurrence of the General Headquarters — ordered his troops on New Guinea , who were within 30 mi ( 48 km ) of their objective of Port Moresby — to withdraw until the Guadalcanal matter was resolved . The Japanese were never able to restart their drive towards Port Moresby ; the defeat at Edson 's Ridge contributed not only to Japan 's defeat in the Guadalcanal campaign , but also to Japan 's ultimate defeat throughout the South Pacific .   After delivering more forces during the next month the Japanese mounted a major ground offensive on Guadalcanal , led by Hyakutake , in late October 1942 at the Battle for Henderson Field , but it resulted in an even more decisive defeat for the Japanese . Vandegrift later stated that Kawaguchi 's assault on the ridge in September was the only time during the entire campaign he had doubts about the outcome and that had it succeeded , " we would have been in a pretty bad condition . " Historian Richard B. Frank adds , " The Japanese never came closer to victory on the island itself than in September 1942 , on a ridge thrusting up from the jungle just south of the critical airfield , best known ever after as Bloody Ridge . "   = New Jersey Route 50 =   Route 50 is a state highway in the southern part of the U.S. state of New Jersey . It runs 26 @.@ 02 mi ( 41 @.@ 88 km ) from an intersection with U.S. Route 9 ( US 9 ) and the Garden State Parkway in Upper Township , Cape May County to an intersection with US 30 and County Route 563 ( CR 563 ) in Egg Harbor City , Atlantic County . The route , which is mostly a two @-@ lane undivided road , passes through mostly rural areas of Atlantic and Cape May counties as well as the communities of Tuckahoe , Corbin City , Estell Manor , and Mays Landing . NJ 50 intersects several roads , including Route 49 in Tuckahoe , US 40 in Mays Landing , and US 322 and the Atlantic City Expressway in Hamilton Township .   The portion of current Route 50 between Seaville and Petersburg received funding in 1910 to become a spur of the Ocean Highway . In 1917 , what is now Route 50 was designated a part of pre @-@ 1927 Route 14 , a route that was to run from Cape May to Egg Harbor City . Route 50 was designated onto its current alignment in 1927 , replacing this portion of pre @-@ 1927 Route 14 . In 1960 , a freeway was proposed for Route 50 , running from the Garden State Parkway in Dennis Township to US 30 in Mullica Township . This proposal was canceled by the
