context_page_description: The Battle for Henderson Field, also known as the Battle of Guadalcanal or Battle of Lunga Point by the Japanese, took place from 23 to 26 October 1942 on and around Guadalcanal in the Solomon Islands. The battle was a land, sea, and air battle of the Pacific campaign of World War II and was fought between the Imperial Japanese Army and Navy and Allied forces, mainly U.S. Marine and Army. The battle was the last of three major land offensives conducted by the Japanese during the Guadalcanal campaign.
  In the battle, U.S. Marine and Army forces under the overall command of Major General Alexander Vandegrift repulsed an attack by the Japanese 17th Army under the command of Lieutenant General Harukichi Hyakutake. However, on the 23rd of October, Vandegrift had flown to Noumea, New Caledonia to meet with Vice Admiral William Halsey Jr., at Halsey's direction. Major General William Rupertus, who was Deputy Commander of the 1st Marine Division, remained in Guadalcanal and commanded the offensive on the ground in Vandegrift's absence.
context_section_description: On 7 August 1942, Allied forces (primarily U.S.) landed on Guadalcanal, Tulagi, and Florida Islands in the Solomon Islands. The landings on the islands were meant to deny their use by the Japanese as bases for threatening the supply routes between the U.S. and Australia, and to secure the islands as starting points for a campaign with the eventual goal of isolating the major Japanese base at Rabaul while also supporting the Allied New Guinea campaign. The landings initiated the six-month-long Guadalcanal campaign.
  Taking the Japanese by surprise, by nightfall on 8 August, the 11,000 Allied troops—under the command of then Major General Alexander Vandegrift and mainly consisting of U.S. Marine Corps units—had secured Tulagi and nearby small islands, as well as an airfield under construction at Lunga Point on Guadalcanal. The airfield was later named "Henderson Field" by Allied forces. The Allied aircraft that subsequently operated out of the airfield became known as the "Cactus Air Force" (CAF) after the Allied codename for Guadalcanal. To protect the airfield, the U.S. Marines established a perimeter defense around Lunga Point.
  In response to the Allied landings on Guadalcanal, the Japanese Imperial General Headquarters assigned the Imperial Japanese Army's 17th Army—a corps-sized command based at Rabaul and under the command of Lieutenant-General Harukichi Hyakutake—with the task of retaking Guadalcanal from Allied forces. On 19 August, various units of the 17th Army began to arrive on Guadalcanal with the goal of driving Allied forces from the island.
  Because of the threat from CAF aircraft based at Henderson Field, the Japanese were unable to use large, slow transport ships to deliver troops and supplies to the island. Instead, the Japanese used warships based at Rabaul and the Shortland Islands to carry their forces to Guadalcanal. The Japanese warships, mainly light cruisers or destroyers from the Eighth Fleet under the command of Vice Admiral Gunichi Mikawa, were usually able to make the round trip down "The Slot" to Guadalcanal and back in a single night, thereby minimizing their exposure to CAF air attack. Delivering the troops in this manner, however, prevented most of the soldiers' heavy equipment and supplies, such as heavy artillery, vehicles, and much food and ammunition, from being carried to Guadalcanal with them. These high speed warship runs to Guadalcanal occurred throughout the campaign and came to be called the "Tokyo Express" by Allied forces and "Rat Transportation" by the Japanese.
  The first Japanese attempt to recapture Henderson Field failed when a 917-man force was defeated on 21 August in the Battle of the Tenaru. The next attempt took place from 12–14 September, with the 6,000 soldiers under the command of Major General Kiyotake Kawaguchi being defeated in the Battle of Edson's Ridge. After their defeat at Edson's Ridge, Kawaguchi and the surviving Japanese troops regrouped west of the Matanikau River on Guadalcanal.
  Hyakutake immediately began to prepare for another attempt to recapture Henderson Field. The Japanese navy promised to support Hyakutake's next offensive by delivering the necessary troops, equipment, and supplies to the island, and by stepping-up air attacks on Henderson Field and sending warships to bombard the airfield.
  As the Japanese regrouped, the U.S. forces concentrated on shoring up and strengthening their Lunga defenses. On 18 September, an Allied naval convoy delivered 4,157 men from the U.S. 7th Marine Regiment to Guadalcanal. This regiment had previously formed part of the 3rd Provisional Marine Brigade and was fresh from garrison duty in Samoa. These reinforcements allowed Vandegrift, beginning on 19 September, to establish an unbroken line of defense completely around the Lunga perimeter.
  General Vandegrift and his staff were aware that Kawaguchi's troops had retreated to the area west of the Matanikau and that numerous groups of Japanese stragglers were scattered throughout the area between the Lunga perimeter and the Matanikau River. Vandegrift, therefore, decided
